AppleTalk Commands
AppleTalk is a LAN system designed and developed by Apple Computer, Inc. It runs over Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI) networks, and LocalTalk, Apple's proprietary twisted-pair media access system. AppleTalk specifies a protocol stack comprising several protocols that direct the flow of traffic over the network.
Apple Computer uses the name AppleTalk to refer to the Apple networking architecture. Apple refers to the actual transmission media used in an AppleTalk network as LocalTalk (Apple's proprietary twisted-pair transmission medium for AppleTalk), TokenTalk (AppleTalk over Token Ring), EtherTalk (AppleTalk over Ethernet), and FDDITalk (AppleTalk over Fiber Distributed Data Interface).
Use the commands in this chapter to configure and monitor AppleTalk networks. For AppleTalk configuration information and examples, refer to the "Configuring AppleTalk" chapter in the Network Protocols Configuration Guide, Part 1.
Note
One or more of the commands that previously appeared this chapter have been replaced by new commands. See the Configuration Fundamentals Command Reference for command information. The old commands continue to perform their normal function in the current release, but support for them will cease in future releases.
access-list additional-zones
To define the default action to take for access checks that apply to zones, use the access-list additional-zones global configuration command.
access-list access-list-number {deny | permit} additional-zones
Syntax Description
access-list-number
Number of the access list. This is a decimal number from 600 to 699.
deny
Denies access if the conditions are matched.
permit
Permits access if the conditions are matched.
Default
No access lists are predefined.
Command Mode
Global configuration
Usage Guidelines
The access-list additional-zones command defines the action to take for access checks not explicitly defined with the access-list zone command. If you do not specify this command, the default action is to deny other access.
You apply access lists defined with the access-list additional-zones command to outgoing routing updates and GZL filters (using the appletalk distribute-list out, and appletalk getzonelist-filter commands). You cannot apply them to data-packet filters (using the appletalk access-group command) or to incoming routing update filters (using the appletalk distribute-list in command).
Example
The following example creates an access list based on AppleTalk zones:
access-list 610 deny zone Twilightaccess-list 610 permit additional-zonesRelated Commands

appletalk distribute-list in
appletalk distribute-list out
appletalk getzonelist-filter
appletalk permit-partial-zonesaccess-list cable-range
To define an AppleTalk access list for a cable range (for extended networks only), use the access-list cable-range global configuration command. To remove an access list, use the no form of this command.
access-list access-list-number {deny | permit} cable-range cable-range
[broadcast-deny | broadcast-permit]
no access-list access-list-number [{deny | permit} cable-range cable-range
[broadcast-deny | broadcast-permit]]Syntax Description
Default
No access lists are predefined.
Command Mode
Global configuration
Usage Guidelines
When used as a routing update filter, the access-list cable-range command affects matching on extended networks only. The conditions defined by this access list are used only when a cable range in a routing update exactly matches that specified in the access-list cable-range command. The conditions are never used to match a network number (for a nonextended network).
When used as a data-packet filter, the access-list cable-range command affects matching on any type of network number. The conditions defined by this access list are used only when the packet's source network lies in the range defined by the access list.
You apply access lists defined with the access-list cable-range command to data-packet and routing-update filters (using the appletalk access-group, appletalk distribute-list in, and appletalk distribute-list out). You cannot apply them to GZL filters (using the appletalk getzonelist-filter command).
To delete an access list, specify the minimum number of keywords and arguments needed to delete the proper access list. For example, to delete the entire access list, use the following command:
no access-list access-list-number
To delete the access list for a specific network, use the following command:
no access-list access-list-number {deny | permit} cable-range cable-range
Priority queuing for AppleTalk operates on the destination network number, not the source network number.
Example
The following access list forwards all packets except those from cable range 10 to 20:
access-list 600 deny cable-range 10-20access-list 600 permit other-accessRelated Commands

To define an AppleTalk access list that overlaps any part of a range of network numbers or cable ranges (for both extended and nonextended networks), use the access-list includes global configuration command. To remove an access list, use the no form of this command.
access-list access-list-number {deny | permit} includes cable-range
[broadcast-deny | broadcast-permit]
no access-list access-list-number [{deny | permit} includes cable-range
[broadcast-deny | broadcast-permit]]Syntax Description
Default
No access lists are predefined.
Command Mode
Global configuration
Usage Guidelines
When used as a routing update filter, the access-list includes command affects matching on extended and nonextended AppleTalk networks. The conditions defined by this access list are used when a cable range or network number overlaps, either partially or completely, one (or more) of those specified in the access-list includes command.
When used as a data-packet filter, the conditions defined by this access list are used when the packet's source network lies in the range defined in the access-list includes command.
You apply access lists defined with the access-list includes command to data-packet and routing-update filters (using the appletalk access-group, appletalk distribute-list in, and appletalk distribute-list out). You cannot apply them to GZL filters (using the appletalk getzonelist-filter command).
To delete an access list, specify the minimum number of keywords and arguments needed to delete the proper access list. For example, to delete the entire access list, use the following command:
no access-list access-list-number
To delete the access list for a specific network, use the following command:
no access-list access-list-number {deny | permit} includes cable-range
Priority queuing for AppleTalk operates on the destination network number, not the source network number.
Example
The following example defines an access list that permits access to any network or cable range that overlaps any part of the range 10 to 20. This means, for example, that cable ranges 13 to 16 and 17 to 25 will be permitted. This access list also permits all other ranges.

priority-list protocol †access-list nbp
To define an AppleTalk access-list entry for a particular NBP named entity (object), class of NBP named entities (type), or NBP named entities belonging to a specific area (zone), use the access-list nbp global configuration command. To remove an NBP access-list entry from the access list, use the no form of this command.
access-list access-list-number {deny | permit} nbp seq {type | object | zone} string
no access-list access-list-number {deny | permit} nbp seq {type | object | zone} stringSyntax Description
Default
No particular access-list entry for an NBP named entity is defined and the default filtering specified by the access-list other-nbps command takes effect.
Command Mode
Global configuration
Usage Guidelines
The access-list nbp command defines the action to take for filtering NBP packets from a particular type (class of named entities), object (particular named entity), or zone (AppleTalk zone in which named entities reside) superceding the default action for NBP packets from all named entities specified by the access-list other-nbps command. For each command that you enter, you must specify a sequence number. The sequence number serves two purposes. Its principal purpose is to allow you to associate two or three portions of an NBP three-part name, referred to as an NBP tuple. To do this, you enter two or three commands having the same sequence number but each specifying a different keyword and NBP name portion: type, object, or zone. The same sequence number binds them together. This provides you with the ability to restrict forwarding of NBP packets at any level, down to a single named entity.
The second purpose of the sequence number is to allow you to keep track of the number of access-list nbp entries you have made. You must enter a sequence number even if you do not use it to associate portions of an NBP name.
Examples
The following example adds entries to access-list number 607 to allow forwarding of NBP packets from specific sources and deny forwarding of NBP packets from all other sources. The first command adds an entry that allows NBP packets from all printers of type LaserWriter. The second command adds an entry that allows NBP packets from all AppleTalk file servers of type AFPServer. The third command adds an entry that allows NBP packets from all applications called HotShotPaint. For example, there might be an application with a zone name of Accounting and an application with a zone name of engineering, both having the object name of HotShotPaint. NBP packets forwarded from both applications will be allowed.
The final access-list other-nbps command denies forwarding of NBP packets from all other sources.

priority-list protocol †access-list network
To define an AppleTalk access list for a single network number (that is, for a nonextended network), use the access-list network global configuration command. To remove an access list, use the no form of this command.
access-list access-list-number {deny | permit} network network
[broadcast-deny | broadcast-permit]
no access-list access-list-number [{deny | permit} network network
[broadcast-deny | broadcast-permit]]Syntax Description
Default
No access lists are predefined.
Command Mode
Global configuration
Usage Guidelines
When used as a routing-update filter, the access-list network command affects matching on nonextended networks only. The conditions defined by this access list are used only when the a nonextended number in a routing update matches a network number specified in one of the access-list network commands. The conditions are never used to match a cable range (for an extended network) even if the cable range has the same starting and ending number.
When used as a data-packet filter, the conditions defined by this access list are used only when the packet's source network matches the network number specified in the access-list network command.
You apply access lists defined with the access-list network command to data-packet and routing-update filters (using the appletalk access-group, appletalk distribute-list in, and appletalk distribute-list out). You cannot apply access lists to GZL filters (using the appletalk getzonelist-filter command).
In software releases before 9.0, the syntax of this command was access-list access-list-number {deny | permit} network. The current version of the software is still able to interpret commands in this format if it finds them in a configuration or boot file. However, it is recommended that you update the commands in your configuration or boot files to match the current syntax.
Use the no access-list command with the access-list-number argument only to remove an entire access list from the configuration. Specify the optional arguments to remove a particular clause.
To delete an access list, specify the minimum number of keywords and arguments needed to delete the proper access list. For example, to delete the entire access list, use the following command:
no access-list access-list-number
To delete the access list for a specific network, use the following command:
no access-list access-list-number {deny | permit} network network
Priority queuing for AppleTalk operates on the destination network number, not the source network number.

No access lists are predefined.
Command Mode
Global configuration
Usage Guidelines
The access-list other-access command defines the action to take for access checks not explicitly defined with an access-list network, access-list cable-range, access-list includes, or access-list within command. If you do not specify this command, the default action is to deny other access.
You apply access lists defined with the access-list other-access command to data-packet and routing-update filters (using the appletalk access-group, appletalk distribute-list in, and appletalk distribute-list out). You cannot apply them to GZL filters (using the appletalk getzonelist-filter command).
In software releases before 9.0, the syntax of this command was access-list access-list-number {deny | permit} -1. The current version of the software is still able to interpret commands in this format if it finds them in a configuration or boot file. However, it is recommended that you update the commands in your configuration or boot files to match the current syntax.
Priority queuing for AppleTalk operates on the destination network number, not the source network number.

no access-list access-list-number {deny | permit} other-nbpsSyntax Description
access-list-number
Number of the access list for AppleTalk. This is a decimal number from 600 to 699.
deny
Denies access if conditions are matched.
permit
Permits access if conditions are matched.
Default
Access is denied.
Command Mode
Global configuration
Usage Guidelines
The access-list other-nbps command defines the action to take for filtering of NBP packets from named entities not explicitly defined by an access-list nbp command. It allows you to implement the default AppleTalk network security state at the named entity level. Any access-list nbp commands you enter affect a particular named entity object, class of named entities, or all named entities within a zone. This command sets the security state for all other NBP named entities. If you do not specify this command, the default action is to deny access.
You can use this command to create an entry in an access list before or after you issue access-list nbp commands. The order of the command in the access list is irrelevant.
Examples
The following example permits forwarding of all NBP packets from all sources except AppleTalk file servers of type AFPServer:

To define an AppleTalk access list for an extended or a nonextended network whose network number or cable range is included entirely within the specified cable range, use the access-list within global configuration command. To remove this access list, use the no form of this command.
access-list access-list-number {deny | permit} within cable-range
no access-list access-list-number [{deny | permit} within cable-range]Syntax Description
Default
No access lists are predefined.
Command Mode
Global configuration
Usage Guidelines
When used as a routing update filter, the access-list within command affects matching on extended and nonextended AppleTalk networks. The conditions defined by this access list are used when a cable range or network number overlaps, either partially or completely, one (or more) of those specified in the access-list within command.
When used as a data-packet filter, the conditions defined by this access list are used when the packet's source network lies in the range defined in the access-list within command.
You apply access lists defined with the access-list within command to data-packet and routing-update (using the appletalk access-group, appletalk distribute-list in, and appletalk distribute-list out). You cannot apply them to GZL filters (using the appletalk getzonelist-filter command).
To delete an access list, specify the minimum number of keywords and arguments needed to delete the proper access list. For example, to delete the entire access list, use the following command:
no access-list access-list-number
To delete the access list for a specific network, use the following command:
no access-list access-list-number {deny | permit} within cable-range
Priority queuing for AppleTalk operates on the destination network number, not the source network number.
Example
The following example defines an access list that permits access to any network or cable range that is completely included in the range 10 to 20. This means, for example, that cable range 13 to 16 will be permitted, but cable range 17 to 25 will not be. The second line of the access list permits all other packets.

You apply access lists defined with the access-list zones command to outgoing routing update and GZL filters (using the appletalk distribute-list out and appletalk getzonelist-filter commands). You cannot apply them to data-packet filters (using the appletalk access-group command) or to incoming routing update filters (using the appletalk distribute-list in command).
To delete an access list, specify the minimum number of keywords and arguments needed to delete the proper access list. For example, to delete the entire access list, use the following command:
no access-list access-list-number
To delete the access list for a specific network, use the following command:
no access-list access-list-number {deny | permit} zone zone-name
Use the access-list additional-zones command to define the action to take for access checks not explicitly defined with the access-list zone command.

Default
No access lists are predefined.
Command Mode
Interface configuration
Usage Guidelines
The appletalk access-group command applies data-packets filter to an interface. These filters check data packets being sent out an interface. If the packets' source network has access denied, these packets are not transmitted but rather are discarded.
Data-packet filters use access lists that define conditions for networks and cable ranges only. They ignore any zone information that may be in the access list.
When you apply a data-packet filter to an interface, you should ensure that all networks or cable ranges within a zone are governed by the same filters.
Example
The following example applies access list 601 to Ethernet interface 0:

Default
Disabled
Command Mode
Interface configuration
Usage Guidelines
You must enable routing on the interface before assigning zone names.
Specifying an address of 0.0, or 0.node places the interface into discovery mode. When in this mode, the Cisco IOS software attempts to determine network address information from another router on the network. You also can enable discovery mode with the appletalk discovery command. Discovery mode does not run over serial lines.
Example
The following example enables nonextended AppleTalk routing on Ethernet interface 0:

no appletalk alternate-addressingSyntax Description
This command has no arguments or keywords.
Default
Disabled
Command Mode
Global configuration
Usage Guidelines
The appletalk alternate-addressing command displays cable ranges in the alternate format wherever applicable. This format consists of printing the upper and lower bytes of a network number as 8-bit decimal values separated by a decimal point. For example, the cable range 511-512 would be printed as 1.255-2.0.
Example
The following example enables the display of network numbers in a two-octet format:
appletalk alternate-addressingappletalk arp interval
To specify the time interval between retransmissions of ARP packets, use the appletalk arp interval global configuration command. To restore both default intervals, use the no form of this command.
appletalk arp [probe | request] interval interval
no appletalk arp [probe | request] interval intervalSyntax Description
Default
If you omit the keywords, probe is the default.
probe—200 ms
request—1000 msCommand Mode
Global configuration
Usage Guidelines
The time interval you specify takes effect immediately.
Lengthening the interval between AARP transmissions permits responses from devices that respond slowly, such as printers and overloaded file servers, to be received.
AARP uses the appletalk arp probe interval value when obtaining the address of the local router. This is done when the Cisco IOS software is being configured. You should not change the default value of this interval unless absolutely necessary, because this value directly modifies the AppleTalk dynamic node assignment algorithm.
AARP uses the appletalk arp request interval value when attempting to determine the hardware address of another node so that it can deliver a packet. You can change this interval as desired, although the default value is optimal for most sites.
The no appletalk arp command restores both the probe and request intervals specified in the appletalk arp interval and appletalk arp retransmit-count commands to their default values.
Example
In the following example, the AppleTalk ARP retry interval is lengthened to 2000 ms:
appletalk arp request interval 2000Related Commands
appletalk arp retransmit-count
appletalk arp-timeout
appletalk glean-packets

To specify the number of AARP probe or request transmissions, use the appletalk arp retransmit-count global configuration command. To restore both default values, use the no form of this command.
appletalk arp [probe | request] retransmit-count number
no appletalk arp [probe | request] retransmit-count numberSyntax Description
Default
If you omit the keyword, probe is the default.
probe—10 transmissions
request—5 transmissionsCommand Mode
Global configuration
Usage Guidelines
The value you specify takes effect immediately.
Increasing the number of retransmissions permits responses from devices that respond slowly, such as printers and overloaded file servers, to be received.
AARP uses the appletalk arp probe retransmit-count value when obtaining the address of the local router. This is done when the Cisco IOS software is being configured. You should not change the default value unless absolutely necessary, because this value directly modifies the AppleTalk dynamic node assignment algorithm.
AARP uses the appletalk arp request retransmit-count value when attempting to determine the hardware address of another node so that it can deliver a packet. You can change this interval as desired, although the default value is optimal for most sites.
The no appletalk arp command restores both the probe and request intervals specified in the appletalk arp interval and appletalk arp retransmit-count commands to their default values.
Example
The following example specifies an AARP retransmission count of 10 for AARP packets that are requesting the hardware address of another node on the network:

Usage Guidelines
If the tunnel peer has not been heard from with the time specified by the least-heard-from timer value, the Cisco IOS software sends tickle packets to check that the tunnel peer is still up.
You can use this command only on tunnel interfaces.
Example
The following example changes the AURP last-heard-from timer value on tunnel interface 0 to 120 seconds:

Specifying a cable range value of 0-0 places the interface into discovery mode. When in this mode, the Cisco IOS software attempts to determine cable range information from another router on the network. You can also enable discovery mode with the appletalk discovery command. Discovery mode does not run over serial lines.
Example
The following example assigns a cable range of 3 to 3 to the interface:
interface ethernet 0appletalk cable-range 3-3Related Commands

To enable the generation and verification of checksums for all AppleTalk packets (except routed packets), use the appletalk checksum global configuration command. To disable checksum generation and verification, use the no form of this command.
appletalk checksum
no appletalk checksumSyntax Description
This command has no arguments or keywords.
Default
Enabled
Command Mode
Global configuration
Usage Guidelines
When the appletalk checksum command is enabled, the Cisco IOS software discards incoming DDP packets when the checksum is not zero and is incorrect, and when the router is the final destination for the packet.
You might want to disable checksum generation and verification if you have very early devices, such as LaserWriter printers, that cannot receive packets that contain checksums.
The Cisco IOS software does not check checksums on routed packets, thereby eliminating the need to disable checksum to allow operation of some networking applications.
Example
The following example disables the generation and verification of checksums:

appletalk client-mode
To allow users to access an AppleTalk zone when dialing into an asynchronous line (on Cisco routers, only via the auxiliary port) use the appletalk client-mode interface configuration command. To disable this function, use the no form of this command.

no appletalk client-modeSyntax Description
This command has no arguments or keywords.
Default
Client mode is disabled.
Command Mode

Usage Guidelines
The appletalk client-mode command allows a remote client to use an asynchronous interface to access AppleTalk zones, use networked peripherals, and share files with other Macintosh users.
This command works only an asynchronous interfaces on which PPP encapsulation is enabled. Also, you must first create an internal network for the Macintosh client using the appletalk virtual-net global configuration command.
An interface configured with the appletalk client-mode and appletalk virtual-net global commands does not support routing.

Command Mode
Interface configuration
Usage Guidelines
If an interface is connected to a network that has at least one other operational AppleTalk router, you can dynamically configure the interface using discovery mode. In discovery mode, an interface acquires network address information about the attached network from an operational router and then uses this information to configure itself.
If you enable discovery mode on an interface, when the Cisco router starts up, that interface must acquire information to configure itself from another operational router on the attached network. If no operational router is present on the connected network, the interface will not start.
If you do not enable discovery mode, then when the router starts, the interface must acquire its configuration from memory. If the stored configuration is not complete, the interface will not start. If there is another operational router on the connected network, the router will verify the interface's stored configuration with that router. If there is any discrepancy, the interface will not start. If there are no neighboring operational routers, the router will assume the interface's stored configuration is correct and will start.
Once an interface is operational, it can seed the configurations of other routers on the connected network regardless of whether you have enabled discovery mode on any of the routers.
If you enable appletalk discovery and the interface is restarted, another operational router must still be present on the directly connected network in order for the interface to start.
It is not advisable to have all routers on a network configured with discovery mode enabled. If all routers were to restart simultaneously (for instance, after a power failure), the network would become inaccessible until at least one router were restarted with discovery mode disabled.
You can also enable discovery mode by specifying an address of 0.0. in the appletalk address command or a cable range of 0-0 in the appletalk cable-range command.
Discovery mode is useful when you are changing a network configuration or when you are adding a router to an existing network.
Discovery mode does not run over serial lines.
Use the no appletalk discovery command to disable discovery mode. If the interface is not operational when you issue this command (that is, if you have not issued an access-list zone command on the interface), you must configure the zone name next. If the interface is operational when you issue the no appletalk discovery command, you can save the current configuration (in running memory) in nonvolatile memory by issuing the copy running-config startup-config command. (The copy running-config startup-config command replaces the write memory command. Refer to the description of the copy running-config startup-config command for more information).

To filter routing updates received from other routers over a specified interface, use the appletalk distribute-list in interface configuration command. To remove the routing table update filter, use the no form of this command.
appletalk distribute-list access-list-number in
no appletalk distribute-list [access-list-number in]Syntax Description
Default
No routing filters are preconfigured.
Command Mode
Interface configuration
Usage Guidelines
The appletalk distribute-list in command controls which networks and cable ranges in routing updates will be entered into the local routing table.
Filters for incoming routing updates use access lists that define conditions for networks and cable ranges only. They cannot use access lists that define conditions for zones. All zone information in an access list assigned to the interface with the appletalk distribute-list in command is ignored.
An input distribution list filters network numbers received in an incoming routing update. When AppleTalk routing updates are received on the specified interface, each network number and cable range in the update is checked against the access list. Only network numbers and cable ranges that are permitted by the access list are inserted into the Cisco IOS software AppleTalk routing table.
Example
The following example prevents the router from accepting routing table updates received from network 10 and on Ethernet interface 3:

Usage Guidelines
The appletalk distribute-list out command controls which network numbers and cable ranges are included in routing updates and which zones the local router includes in its GetZoneList replies.
When an AppleTalk routing update is generated on the specified interface, each network number and cable range in the routing table is checked against the access list. If an undefined access list is used, all network numbers and cable ranges are added to the routing update. Otherwise, if an access list is defined, only network numbers and cable ranges that satisfy the following conditions are added to the routing update:
•
•
•
A zone is considered partially obscured when one or more network numbers or cable ranges that are members of the zone is explicitly or implicitly denied.
When a ZIP GetZoneList reply is generated, only zones that satisfy the following conditions are included:

Default
No domain number is assigned to the interface.
Command Mode

Usage Guidelines
Before you can assign a domain number to an interface, you must create a domain with that domain number using the appletalk domain name global configuration command.
One or more interfaces on a router can be members of the same domain. However, a given interface can be in only one domain.
After you assign AppleTalk interenterprise features to an AppleTalk domain, you can attribute those features to a tunnel interface configured for AURP by assigning the AppleTalk domain-group number to the tunnel interface.
Examples
The following example assigns domain group 1 to Ethernet interface 0:
interface ethernet 0appletalk domain-group 1The following example assigns domain group 1 to tunnel interface 2. Assuming that domain group 1 is configured for AppleTalk interenterprise and that tunnel interface 2 is configured for AURP, any features configured for domain group 1 are ascribed to AURP on tunnel interface 2.

no appletalk domain domain-number hop-reductionSyntax Description
Default
Reduction of hop-count values is disabled.
Command Mode
Global configuration
Usage Guidelines
Before you can specify the appletalk domain hop-reduction global configuration command, you must have created a domain with that domain number using the appletalk domain name global configuration command.
DDP and RTMP both impose a 15-hop limit when forwarding packets. A packet ages out and is no longer forwarded when its hop count reaches 16. To overcome RTMP's 15-hop limit, the domain router represents all networks accessible to routers on its local network as one hop away. This allows routers to maintain and send routing information about networks beyond the 15-hop limit and achieve full connectivity.
When you enable hop-count reduction, delivery of packets from networks that are farther than
15 hops apart is guaranteed.When you enable hop-count reduction, the hop count in a packet is set to 1 as it passes from one domain to another. For example, if the hop count was 8 when the packet left one domain, its hop count is 1 when it enters the next segment of the domain.
Example
The following example enables hop-count reduction for domain number 1:

no appletalk domain domain-number remap-range {in | out} [cable-range]Syntax Description
Default

Usage Guidelines
Before you can specify the appletalk domain remap-range command, you must create a domain with that domain number using the appletalk domain name global configuration command.
Inbound and outbound packets are relative to the domain router.
Ensure that the domain range you specify does not overlap any network addresses or cable ranges that already exist in the AppleTalk interenterprise network.
Each domain can have two domain mapping ranges to which to remap all incoming or outgoing network numbers or cable ranges. Incoming remapping ranges cannot overlap. However, outbound remapping ranges can overlap.
When an AppleTalk network in a domain becomes inactive, its remapped entry is removed from the remapping table. This frees the space for another network to be remapped.
If there are more remote domains than available remapping range numbers, the Cisco IOS software displays an error message and shuts down domains.
Example
The following example remaps all network addresses and cable ranges for packets inbound from domain 1 into the address range 1000 to 1999. It also remaps packets inbound from domain 2.

This command allows you to configure the length of time that Enhanced IGRP routes can remain active. When a route reaches the active state time limit, the Cisco IOS software logs an error and removes the route from the routing table. You can view the current setting of the Enhance IGRP active state time by using the show appletalk globals command.

To configure split horizon, use the appletalk eigrp-splithorizon interface configuration command. To disable split horizon, use the no form of this command.
appletalk eigrp-splithorizon
no appletalk eigrp-splithorizonSyntax Description
This command has no arguments or keywords.
Default
Enabled
Command Mode
Interface configuration
Usage Guidelines
If you enable split horizon on an interface, AppleTalk Enhanced IGRP update and query packets are not sent if this interface is the next hop to that destination. This reduces the number of Enhanced IGRP packets of the network.
Split horizon blocks information about routes from being advertised by a router out any interface from which that information originated. This behavior usually optimizes communication among multiple routers, particularly when links are broken. However, with nonbroadcast networks, such as Frame Relay and SMDS, situations can arise for which this behavior is less than ideal. For these situations, you may wish to disable split horizon.
Example
The following example disables split horizon on serial interface 0:
interface serial 0no appletalk eigrp-splithorizonappletalk eigrp-timers
To configure the AppleTalk Enhanced IGRP hello packet interval and the route hold time, use the appletalk eigrp-timers interface configuration command. To return to the default values for these timers, use the no form of this command.

For low-speed NBMA networks: 60 seconds
For all other networks: 5 seconds
hold-time:
For low-speed NBMA networks: 180 seconds
For all other networks: 15 secondsCommand Mode
Interface configuration
Usage Guidelines
If the current value for the hold time is less than two times the hello interval, the hold time is reset to three times the hello interval.
If the Cisco IOS software does not receive a hello packet within the specified hold time, routes through this device are considered available.
Increasing the hold time delays route convergence across the network.
Note
The default of 180 seconds for hold-time applies only to low-speed, nonbroadcast, multiaccess (NBMA) media. Low speed is considered to be a rate of T1 or slower, as specified with the bandwidth interface configuration command.
The default of 60 seconds for hello-interval applies only to low-speed NBMA media. Low speed is considered to be a rate of T1 or slower, as specified with the bandwidth interface configuration command. Note that for purposes of Enhanced IGRP, Frame Relay and SMDS networks may or may not be considered to be NBMA. These networks are considered NBMA if the interface has not been configured to use physical multicasting; otherwise they are considered not to be NBMA.
Example
The following example changes the hello interval to 10 seconds:

A free-trade zone is a part of an AppleTalk internet that is accessible by two other parts of the internet, neither of which can access the other. You might want to create a free-trade zone to allow the exchange of information between two organizations that otherwise want to keep their internets isolated from each other or that do not have physical connectivity with one another.
You apply the appletalk free-trade-zone command to each interface attached to the common-access network. This command has the following effect on the interface:
•

•
The GZL for free-trade zone nodes will be empty.
Example
The following example establishes a free-trade zone on Ethernet interface 0:

no appletalk getzonelist-filter [access-list-number]Syntax Description
Default
No filters are preconfigured.
Command Mode
Interface configuration
Usage Guidelines
GZL filters define conditions for zones only. They cannot use access lists that define conditions for network numbers or cable ranges. All network number and cable range information in the access list assigned to an interface with the appletalk getzonelist-filter command is ignored.
Using a GZL filter is not a complete replacement for anonymous network numbers. In order to prevent users from seeing a zone, all routers must implement the GZL filter. If there are any routers from other vendors on the network, the GZL filter will not have a consistent effect.
The Macintosh Chooser uses ZIP GZL requests to compile a list of zones from which the user can select services. Any router on the same network as the Macintosh can respond to these requests with a GZL reply. You can create a GZL filter on the router to control which zones the router mentions in its GZL replies. This has the effect of controlling the list of zones that are displayed by the Chooser.
When defining GZL filters, you should ensure that all routers on the same internetwork filter GZL reply identically. Otherwise, the Chooser will list different zone depending upon which router responded to the request. Also, inconsistent filters can result in zones appearing and disappearing every few seconds when the user remains in the Chooser. Because of these inconsistencies, you should normally use the appletalk getzonelist-filter command only when all routers in the internetwork are our routers, unless the other vendors' routers have a similar feature.
Replies to GZL requests are also filtered by anyappletalk distribute-list out filter that has been applied to the same interface. You need to specify an appletalk getzonelist-filter command only if you want additional filtering to be applied to GZL replies. This filter is rarely needed except to eliminate zones that do not contain user services.

Usage Guidelines
The Cisco IOS software automatically derives AARP table entries from incoming packets. This process is referred to as "gleaning." Gleaning speeds up the process of populating the AARP table.
Our implementation of AppleTalk does not forward packets with local source and destination network addresses. This behavior does not conform with the definition of AppleTalk in Apple Computer's Inside AppleTalk publication. However, this behavior is designed to prevent any possible corruption of the AARP table in any AppleTalk node that is performing MAC-address gleaning.
Example
The following example disables the building of the AARP table using information derived from incoming packets:

To enable IPTalk encapsulation on an interface that already has a configured IP address, use the appletalk iptalk interface configuration command. To disable IPTalk encapsulation, use the no form of this command.
appletalk iptalk network.node zone
no appletalk iptalk [network.node zone]Syntax Description
Default
Disabled
Command Mode
Interface configuration
Usage Guidelines
Use the appletalk iptalk command to enable IPTalk encapsulation on an interface that already has a configured IP address. This command encapsulates AppleTalk in IP packets in a manner compatible with the Columbia AppleTalk Package (CAP) IPTalk and the Kinetics IPTalk implementations.
This command allows AppleTalk communication with UNIX hosts running older versions of CAP that do not support native AppleTalk EtherTalk encapsulations. Typically, Apple Macintosh users wishing to communicate with these servers would have their connections routed through a Kinetics FastPath router running Kinetics IPTalk software.
This command is provided as a migration command; newer versions of CAP provide native AppleTalk EtherTalk encapsulations, and the IPTalk encapsulation is no longer required. Our implementation of IPTalk assumes that AppleTalk is already being routed on the backbone; there is currently no LocalTalk hardware interface for our routers.
Our implementation of IPTalk does not support manually configured AppleTalk-to-IP address mapping (atab). The address mapping provided is the same as the Kinetics IPTalk implementation when the atab facility is not enabled. This address mapping functions as follows: The IP subnet mask used on the Ethernet interface on which IPTalk is enabled is inverted (ones complement). This result is then masked against 255 (0xFF hexadecimal). This is then masked against the low-order 8 bits of the IP address to obtain the AppleTalk node number.
Example
The following example configuration illustrates how to configure IPTalk:
interface Ethernet 0ip address 131.108.1.118 255.255.255.0appletalk address 20.129appletalk zone Native AppleTalkappletalk iptalk 30.0 UDPZoneIn this configuration, the IP subnet mask would be inverted:
255.255.255.0 inverted yields: 0.0.0.255Masked with 255 it yields 255, and masked with the low-order 8 bits of the interface IP address it yields 118.
This means that the AppleTalk address of the Ethernet 0 interface seen in the UDPZone zone is 30.118. This caveat should be noted, however: Should the host field of an IP subnet mask for an interface be more than 8 bits wide, it will be possible to obtain conflicting AppleTalk node numbers. For instance, consider a situation where the subnet mask for the Ethernet 0 interface above is 255.255.240.0, meaning that the host field is 12 bits wide.

port-number
First UDP port number in the range of UDP ports used in mapping AppleTalk well-known DDP socket numbers to UDP ports.
Default
768
Command Mode
Global configuration
Usage Guidelines
Implementations of IPTalk prior to April 1988 mapped well-known DDP socket numbers to privileged UDP ports starting at port number 768. In April 1988, the NIC assigned a range of UDP ports for the defined DDP well-known sockets starting at UDP port number 200 and assigned these ports the names at-nbp, at-rtmp, at-echo, and at-zis. Release 6 and later of the CAP program dynamically decides which port mapping to use. If there are no AppleTalk service entries in the UNIX system's /etc/services file, CAP uses the older mapping starting at UDP port number 768.
The default UDP port mapping supported by our implementation of IPTalk is 768. If there are AppleTalk service entries in the UNIX system's /etc/services file, you should specify the beginning of the UDP port mapping range with the appletalk iptalk-baseport command.
Example
The following example sets the base UDP port number to 200, which is the official NIC port number, and configures IPTalk on Ethernet interface 0:

To display information that is stored in the name cache about the services being used by our routers and other vendors' routers, use the show appletalk name-cache command.
If a neighboring router is not our device or is running our software that is earlier than Release 9.0, it is possible our device will be unable to determine the name of the neighbor. This is normal behavior, and there is no workaround.
If AppleTalk routing is enabled, enabling SNMP will automatically enable SNMP over DDP.
Name cache entries are deleted after several interval periods expire without being refreshed. (You set the interval with the appletalk name-lookup-interval command.) At each interval, a single request is sent via each interface that has valid addresses.

The following example caches information about GatorBox services, Apple internet routers, MacIP services, and workstations. Information about our devices is automatically cached.

Usage Guidelines
Use the appletalk macip dynamic command when configuring MacIP.
Dynamic clients are those that accept any IP address assignment within the dynamic range specified.
In general, it is recommended that you do not use fragmented address ranges in configuring ranges for MacIP. However, if this is unavoidable, use the appletalk macip dynamic command to specify as many addresses or ranges as required and use the appletalk macip static command to assign a specific address or address range.
To shut down all running MacIP services, use the following command:

Usage Guidelines
Use the appletalk macip server command when configuring MacIP.
You can configure only one MacIP server per AppleTalk zone, and the server must reside in the default zone. A server is not registered via NBP until at least one MacIP resource is configured.
You can configure multiple MacIP servers for a router, but you can assign only one MacIP server to a particular zone and only one IP interface to each MacIP server. In general, you must be able to establish an alias between the IP address you assign with the appletalk macip server command and an existing IP interface. For implementation simplicity, it is suggested that the address specified in this command match an existing IP interface address.
To shut down all active MacIP servers, use the following command:
no appletalk macip
To delete a specific MacIP server from the MacIP configuration, use the following command:
no appletalk macip server ip-address zone server-zone
Example
The following example establishes a MacIP server on Ethernet interface 0 in AppleTalk zone Engineering. It then assigns an IP address to the Ethernet interface and enables AppleTalk routing on a router and its Ethernet interface.

Usage Guidelines
Use the appletalk macip static command when configuring MacIP.
Static addresses are for users who require fixed addresses for IP name domain name service and for administrators who do want addresses to change so they can always know who has what IP address.
In general, it is recommended that you do not use fragmented address ranges in configuring ranges for MacIP. However, if this is unavoidable, use the appletalk macip dynamic command to specify as many addresses or ranges as required, and then use the appletalk macip static command to assign a specific address or address range.
To shut down all running MacIP services, use the following command:

To set the interval between service pollings by the router on its AppleTalk interfaces, use the appletalk name-lookup-interval global configuration command. To purge the name cache and return to the default polling interval, use the no form of this command.
appletalk name-lookup-interval seconds
no appletalk name-lookup-interval [seconds]Syntax Description
seconds
Interval, in seconds, between NBP lookup pollings. This can be any positive integer; there is no upper limit. It is recommended that you use an interval between 300 seconds (5 minutes) and 1200 seconds (20 minutes). The smaller the interval, the more packets are generated to handle the names. Specifying an interval of 0 purges all entries from the name cache and disables the caching of service type information that is controlled by the appletalk lookup-type command, including the caching of information about our routers.
Default
Zero (0), which purges all entries from the name cache and disables the caching of service type information.
Command Mode
Global configuration
Usage Guidelines
The Cisco IOS software collects name information only for entities on connected AppleTalk networks. This reduces overhead.
If you enter an interval of 0, all polling for services (except ciscoRouter) is disabled. If you reenter a nonzero value, the configuration specified by the appletalk lookup-type command is reinstated. You cannot disable the lookup of ciscoRouter.

Usage Guidelines
You can configure an interface to use both RTMP and Enhanced IGRP. If you do so, route information learned from Enhanced IGRP will take precedence over information learned from RTMP. The Cisco IOS software will, however, continue to send out RTMP routing updates.
You cannot disable RTMP without first enabling AURP or Enhanced IGRP.
Enabling AURP automatically disables RTMP.
You can enable AURP only on tunnel interfaces.

appletalk proxy-nbp
To assign a proxy network number for each zone in which there is a router that supports only nonextended AppleTalk, use the appletalk proxy-nbp global configuration command. To delete the proxy, use the no form of this command.
appletalk proxy-nbp network-number zone-name
no appletalk proxy-nbp [network-number zone-name]Syntax Description
Default
No proxy network number is assigned.
Command Mode
Global configuration
Usage Guidelines
The appletalk proxy-nbp command provides compatibility between AppleTalk Phase 1 and AppleTalk Phase 2 networks.
Proxy routes are included in outgoing RTMP updates as if they were directly connected routes, although they are not really directly connected, since they are not associated with any interface. Whenever an NBQ BrRq for the zone in question is generated by anyone anywhere in the Internet, an NBP FwdReq is directed to any router connected to the proxy route. The Phase 2 router which is the only router directly connected converts the FwdReq to LkUps, which are understood by Phase 1 routers, and sends them to every network in the zone.
In an environment in which there are Phase 1 and Phase 2 networks, you must specify at least one appletalk proxy-nbp command for each zone that has a nonextended-only AppleTalk router.
The proxy network number you assign with the appletalk proxy-nbp command cannot also be assigned to a router, nor can it also be associated with a physical network.
You need to assign only one proxy network number for each zone. However, you can define additional proxies with different network numbers to provide redundancy. Each proxy generates one or more packets for each forward request it receives. All other packets sent to the proxy network address are discarded. Defining redundant proxy network numbers increases the NBP traffic linearly.
Example
The following example defines network number 60 as an NBP proxy for the zone Twilight:
appletalk proxy-nbp 60 TwilightRelated Command
show appletalk routeappletalk require-route-zones
To prevent the advertisement of routes (network numbers or cable ranges) that have no assigned zone, use the appletalk require-route-zones global configuration command. To disable this option and allow the Cisco IOS software to advertise to its neighbors routes that have no network-zone association, use the no form of this command.
appletalk require-route-zones
no appletalk require-route-zonesSyntax Description
This command has no arguments or keywords.
Default
Enabled
Command Mode
Global configuration
Usage Guidelines
The appletalk require-route-zones command ensures that all networks have zone names prior to advertisement to neighbors.
The no appletalk require-route-zones command enables behavior compatible with Cisco IOS software Release 8.3.
Using this command helps prevent ZIP protocol storms. ZIP protocol storms can arise when corrupt routes are propagated and routers broadcast ZIP requests to determine the network/zone associations.
When the appletalk require-route-zones command is enabled, the Cisco IOS software will not advertise a route to its neighboring routers until it has obtained the network-zone associations. This effectively limits the storms to a single network rather than the entire internet.
As an alternative to disabling this option, use the appletalk getzonelist-filter interface configuration command to filter empty zones from the list presented to users.
You can configure different zone lists on different interfaces. However, you are discouraged from doing this because AppleTalk users expect to have the same user zone lists at any end node in the internet.
The filtering provided by the appletalk require-route-zones command does not prevent explicit access via programmatic methods, but should be considered a user optimization to suppress unused zones. You should use other forms of AppleTalk access control lists to actually secure a zone or network.
Example
The following example configures a router to prevent the advertisement of routes that have no assigned zone:
appletalk require-route-zonesappletalk route-cache
To enable fast switching on all supported interfaces, use the appletalk route-cache interface configuration command. To disable fast switching, use the no form of this command.
appletalk route-cache
no appletalk route-cacheSyntax Description
This command has no arguments or keywords.
Default
Enabled on all interfaces that support fast switching
Command Mode
Interface configuration
Usage Guidelines
Fast switching allows higher throughput by switching a packet using a cache created by previous packets. Fast switching is enabled by default on all interfaces that support fast switching, including Token Ring, Frame Relay, PPP, HDLC, SMDS, and ATM. Note that fast switching is not supported over X.25 and LAPB encapsulations, or on the CSC-R16, CSC-1R, or CSC-2R STR Token Ring adapters.
Packet transfer performance is generally better when fast switching is enabled. However, you may want to disable fast switching in order to save memory space on interface cards and to help avoid congestion when high-bandwidth interfaces are writing large amounts of information to low-bandwidth interfaces.
Fast switching of extended AppleTalk is supported on serial lines with several encapsulation types (for example, SMDS and HDLC). Fast switching of nonextended AppleTalk is not supported on serial lines.
Example
The following example disables fast switching on an interface:

appletalk route-redistribution
To redistribute RTMP routes into AppleTalk Enhanced IGRP and vice versa, use the appletalk route-redistribution global configuration command. To keep Enhanced IGRP and RTMP routes separate, use the no form of this command.
appletalk route-redistribution
no appletalk route-redistributionSyntax Description
This command has no arguments or keywords.
Default
Enabled when Enhanced IGRP is enabled
Command Mode
Global configuration
Usage Guidelines
Redistribution allows routing information generated by one protocol to be advertised in another.
In the automatic redistribution of routes between Enhanced IGRP and RTMP, an RTMP hop is treated as having a slightly worse metric than an equivalent Enhanced IGRP hop on a 9.6-kilobit link. This allows Enhanced IGRP to be preferred over RTMP except in the most extreme of circumstances. Typically, you will see this only when using tunnels. If you want an Enhanced IGRP path in a tunnel to be preferred over an alternate RTMP path, you should set the interface delay and bandwidth parameters on the tunnel to bring the metric of the tunnel down to being better than a 9.6-kilobit link.
Example
In the following example, RTMP routing information is not redistributed:
appletalk routing eigrp 23no appletalk route-redistributionappletalk routing
To enable AppleTalk routing, use the appletalk routing global configuration command. To disable AppleTalk routing, use the no form of this command.
appletalk routing [eigrp router-number]
no appletalk routing [eigrp router-number]Syntax Description
Default
Disabled
Command Mode
Global configuration
Usage Guidelines
If you do not specify the optional keyword and argument, this command enables AppleTalk routing using the RTMP routing protocol.
You can configure multiple AppleTalk Enhanced IGRP processes on a router. To do so, assign each a different router ID number. (Note that IP and IPX Enhanced IGRP use an autonomous system number to enable Enhanced IGRP, while AppleTalk Enhanced IGRP uses a router ID.)
If you configure a device with a router number that is the same as that of a neighboring router, the Cisco IOS software will refuse to start AppleTalk Enhanced IGRP on interfaces that connect with that neighboring router.
CautionWhen disabling Enhanced IGRP routing with the no appletalk routing eigrp command, all interfaces enabled for only Enhanced IGRP (and not also RTMP) lose their AppleTalk configuration. If you want to disable Enhanced IGRP and use RTMP instead on specific interfaces, first enable RTMP on each interface using the appletalk protocol rtmp interface configuration command. Then, disable Enhanced IGRP routing using the no appletalk routing eigrp command. This process ensures that you do not lose AppleTalk configurations on interfaces for which you want to use RTMP.

appletalk rtmp-stub
no appletalk rtmp-stubSyntax Description
This command has no arguments or keywords.
Default
Disabled
Command Mode
Interface configuration
Usage Guidelines
This command enables routers running Enhanced IGRP and RTMP to reduce the amount of CPU processing that RTMP modules use. RTMP modules send "stub" packets instead of full RTMP packets when you enable stub mode.
A stub packet is only the first tuple of an RTMP packet. The first tuple indicates the network number range assigned to that network. End nodes use stub packets to determine if their node number is in the right network range.
Upon startup, an end node on an extended network uses stub packets to verify that its previous node number is still within the segment's network number range. If it is, the end node reuses the previous node number and stores the network number range information. If an end node learns upon startup that its previous node number does not fall within the segment's new network number range, the end node picks a new node number based on the new network number range and stores the new network number range information.
After startup, end nodes use subsequent stub packets to verify that the network number range sent in the stub packets precisely matches its stored network number range. In this way, stub packets keep end nodes alive.
When routers that have stub mode enabled receive full RTMP packets, they discard these packets because Enhanced IGRP (not RTMP) is expected to deliver routes. Discarding full RTMP packets when stub mode is enabled saves the overhead processing of RTMP routes.
You can also use stub mode on "end" networks. End networks are those to which no other routers attach. Because no other routers are listening for routes on these end segments, there is no need for the end router to send full RTMP packets to these end segments. The end router can send stub packet to keep end nodes alive.
Example
The following example turns on AppleTalk RTMP stub mode:

Default

Command Mode
Global configuration
Usage Guidelines
You cannot delete a particular zone from the zone list without first deleting the static route.
When links associated with static routes are lost, traffic may stop being forwarded even though alternative paths might be available. For this reason, you should be careful when assigning static routes.
Floating static routes are a kind of static route that can be overridden by dynamically learned routes. Floating static routes allow you to switch to another path whenever routing information for a destination is lost. One application of floating static routes is to provide back-up routes in topologies where dial-on-demand routing is used.
If you configure a floating static route, the Cisco IOS software checks to see if an entry for the route already exists in its routing table. If a dynamic route already exists, the floating static route is placed in reserve as part of a floating static route table. When the software detects that the dynamic route is no longer available, it replaces the dynamic route with the floating static route for that destination. If the route is later relearned dynamically, the dynamic route replaces the floating static route and the floating static route is again placed in reserve.
To avoid the possibility of a routing loop occurring, by default floating static routes are not redistributed into other dynamic protocols.
Examples
The following example creates a static route to the remote router whose address is 1.2 on the remote network 100-110 that is in the remote zone Remote:

Defaults

Global configuration
Usage Guidelines
Routes older than the time specified by update-interval are considered suspect. Once the period of time specified by valid-interval has elapsed without having heard a routing update for a route, the route becomes bad and is eligible for replacement by a path with a higher (less favorable) metric. During the invalid-interval period, routing updates include this route with a special "notify neighbor" metric. If this timer expires, the route is deleted from the routing table.
Note that you should not attempt to modify the routing timers without fully understanding the ramifications of doing so. Many other AppleTalk router vendors provide no facility for modifying their routing timers; should you adjust the Cisco IOS software AppleTalk timers such that routing updates do not arrive at these other routers within the normal interval, it is possible to degrade or destroy AppleTalk network connectivity.
If you change the routing update interval, be sure to do so for all routers on the network.
In rare instances, you might want to change this interval, such as when a device is busy and cannot send routing updates every 10 seconds or when slower routers are incapable of processing received routing updates in a large network.
Example
The following example increases the update interval to 20 seconds and the route-valid interval to 40 seconds:

Default
No virtual networks are predefined.
Command Mode

Usage Guidelines
A virtual network is a logical network that exists only within the Cisco IOS software. It enables you—and by extension anyone who dials into the router—to add an asynchronous interface to either a new or an existing AppleTalk zone.
Virtual networks work with both extended and nonextended AppleTalk networks. On Cisco routers, you can only set a virtual network on an asynchronous line on the auxiliary port.
If you issue the appletalk virtual-net command and specify a new AppleTalk zone name, the network number you specify is the only one associated with this zone. If you issue this command and specify an existing AppleTalk zone, the network number you specify is added to the existing zone.
The selected AppleTalk zone (either new or existing) is highlighted when you open the Macintosh Chooser window. From this window, you can access all available zones.

Command Mode
Interface configuration
Usage Guidelines
ZIP reply filters limit the visibility of zones from routers in unprivileged regions throughout the internetwork. These filters screen the zone list for each network provided by a router to neighboring routers to remove restricted zones.
ZIP reply filters apply to downstream routers, not to end stations on networks attached to the local router. If you configure ZIP reply filters, the local router sends only the names of visible zones to downstream routers requesting the names of zones in a network. The local router does not send the names of zones that have been hidden with a ZIP reply filter.
To filter zones from end stations, use GZL filters.
ZIP reply filters determine the networks and cable ranges that the Cisco IOS software sends out in routing updates. Before sending out routing updates, the software excludes the networks and cable ranges whose zones have been completely denied access by ZIP reply filters. Excluding this information ensures that routers receiving these routing updates do not send unnecessary ZIP requests.

To set the zone name for the connected AppleTalk network, use the appletalk zone interface configuration command. To delete a zone, use the no form of this command.
appletalk zone zone-name
no appletalk zone [zone-name]Syntax Description
Default
No zone name is set.
Command Mode
Interface configuration
Usage Guidelines
If discovery mode is not enabled, you can specify the appletalk zone command only after an appletalk address or appletalk cable-range command. You can issue it multiple times if it follows the appletalk cable-range command.
On interfaces that have discovery mode disabled, you must assign a zone name in order for AppleTalk routing to begin.
If an interface is using extended AppleTalk, the first zone specified in the list is the default zone. The Cisco IOS software always uses the default zone when registering NBP names for interfaces. Nodes in the network will select the zone in which they will operate from the list of zone names valid on the cable to which they are connected.
If an interface is using nonextended AppleTalk, repeated execution of the appletalk zone command will replace the interface's zone name with the newly specified zone name.
The no form of the command deletes a zone name from a zone list or deletes the entire zone list if you do not specify a zone name. For nonextended AppleTalk interfaces, the zone name argument is ignored. You should delete any existing zone-name list using the no appletalk zone interface subcommand before configuring a new zone list.
The zone list is cleared automatically when you issue an appletalk address or appletalk cable-range command. The list also is cleared if you issue the appletalk zone command on an existing network; this can occur when adding zones to a set of routers until all routers are in agreement.
Examples
The following example assigns the zone name Twilight to an interface:
interface Ethernet 0appletalk cable-range 10-20appletalk zone TwilightThe following example uses AppleTalk special characters to set the zone name to Cisco:A5Zone.

show appletalk nbp
Syntax Description
This command has no arguments or keywords.
Command Mode
EXEC
Usage Guidelines
The show appletalk nbp command lets you identify specific AppleTalk nodes. It displays services registered by the router. In contrast, use the show appletalk name-cache command to display any AppleTalk services of interest in local zones.
Routers with active AppleTalk interfaces register each interface separately. The Cisco IOS software generates a unique interface NBP name by appending the interface type name and unit number to the router name. For example, for the router named "router" that has AppleTalk enabled on Ethernet interface 0 in the zone Marketing, the NBP registered name is as follows:
router.Ethernet0:ciscoRouter@MarketingRegistering each interface on the router provides you with an indication that the device is configured and operating properly.
One name is registered for each interface. Other service types are registered once for each zone.
The Cisco IOS software deregisters the NBP name if AppleTalk is disabled on the interface for any reason.

To display all entries or specified entries in the zone information table, use the show appletalk zone EXEC command.
show appletalk zone [zone-name]
Syntax Description
Command Mode
EXEC
Usage Guidelines
If no zone name is specified, the command displays all entries in the zone information table.
You can use this command on extended and nonextended networks.
A zone name can be associated with multiple network addresses or cable ranges, or both. There is not a one-to-one correspondence between a zone name and a LAN; a zone name may correspond to one or more networks (LANs or network interfaces). This means that a zone name will effectively replace multiple network addresses in zone filtering. This is reflected in the output of the show appletalk zone command. For example, the zone named Mt. View 1 in the sample display below is associated with two network numbers and four cable ranges.

show smrp forward
To display all entries or specific entries in the SMRP forwarding table, use the show smrp forward EXEC command.
show smrp forward [appletalk [group-address]]
Syntax Description
Command Mode
EXEC
Usage Guidelines
The SMRP forwarding table describes the relationship between the SMRP router and the distribution tree for each SMRP group on the Internet. An SMRP router has an entry in this table for every SMRP group for which the router is forwarding data. When data for an SMRP group arrives on the parent interface, it is forwarded to each child interface.
Looking at child and parent interfaces in relation to members of an SMRP group, a child interface is a neighbor that is farther away from the SMRP creator node and a parent interface is one that is closer to the creator node.
If no SMRP group address is specified, then the show smrp forward command displays information for all entries in the SMRP forwarding table. For all entries, the show smrp forward command displays the SMRP group address, the state of the SMRP group, the parent interface and address, and one or more child interfaces and addresses.
If an SMRP group address is specified, the command displays additional information for that group showing the child count, the time elapsed since the entry was updated, and the next poll time.

show smrp mcache
To display the SMRP fast switching cache table, use the show smrp mcache EXEC command.
show smrp mcache [appletalk [group-address]]
Syntax Description
Command Mode
EXEC
Usage Guidelines
An SMRP router has an entry in its forwarding table for every SMRP group for which the router forwards data. For each group, the forwarding table lists the parent interface and address and one or more child interfaces and addresses. When data for an SMRP group arrives on the parent interface, the router forwards it to each child interface. The SMRP fast switching cache table specifies whether or not to fast switch SMRP data packets out the interfaces specified by the forwarding table.
Use show smrp mcache command to view the SMRP fast switching cache table. The command displays which interfaces are fast-switch enabled. If a parent interface is not fast-switch enabled, then there is no entry (row) in the table. If a child interface is not fast-switch enabled, then it is not in the list of child interfaces for an entry in the table.
If you do not specify an SMRP group address, then the show smrp mcache command displays information for all entries in the SMRP fast switching cache table. If you specify an SMRP group address, the command displays cache entries for only that group.
SMRP fast switching is enabled by default.

To display all entries or specific entries in the SMRP neighbor table, use the show smrp neighbor EXEC command.
show smrp neighbor [appletalk [network-address]]
Syntax Description
Command Mode
EXEC
Usage Guidelines
A neighbor is an adjacent router. Neighboring routers keep track of one another by sending and receiving hello packets periodically. Using this method, the Cisco IOS software can determine if it has heard from a neighbor router within a certain amount of time. The software creates an entry in its neighbor table when it finds a neighboring route. The software maintains the entry, indicating, among other information, the current state of the neighbor. The software updates the entry if the state of the neighbor router changes; for example, a secondary router became a primary router. The secondary router is the router that becomes the primary router when the primary router is no longer heard from.
For all neighboring routers, the show smrp neighbor command displays the address of the neighbor router, the state of the neighbor, its interface, the last time it was heard from, its route version number, and whether or not routes need to be sent to the neighbor. If the network address of a specific neighbor is given as a command parameter, this information is displayed for that neighbor router only.

Default
Enabled
Command Mode
Interface configuration
Usage Guidelines
By default, fast switching is enabled on all SMRP ports. A network protocol and interface comprise an SMRP port. Fast switching improves the throughput rate by processing incoming packets more quickly than process switching.
SMRP uses the forwarding table to forward packets for a particular SMRP group. For each group, the forwarding table lists the parent interface and address and one or more child interfaces and addresses. When data for an SMRP group arrives on the parent interface, the router forwards it to each child interface. The SMRP fast switching cache table specifies whether or not to fast switch SMRP data packets out the interfaces specified by the forwarding table.
SMRP fast switching requires that:
•
•
When the parent port is fast-switch enabled, the system populates and validates a fast switching cache table when forwarding packets out child ports.
To populate the fast switching cache table with fast switching information, the first packets are process switched. Thus, the fast switching cache table is populated with information about fast-switch enabled child ports. When succeeding packets arrive, the system uses the SMRP fast switching cache table to fast switch the packets out those child ports.
If there are non-fast switching ports in the forwarding table, then the system process switches the packet out those ports.
To validate the fast switching cache table, the system validates each cache entry when it forwards the first packet out all child ports. If a cache entry is validated, the router can use the entry to fast switch succeeding packets out the child ports.
If a cache entry is invalidated, the router cannot use the entry to fast switch packets. The entry is removed from the fast switching cache table and the router process switches packets out the child ports. A cache entry is invalidated when one of these conditions is met:

Default
SMRP is disabled.
Command Mode
Interface configuration
Usage Guidelines
SMRP supports point-to-multipoint multicasting of packets for AppleTalk networks. This support provides the capability of sending data from a single source to multiple stations without having to send duplicate copies of the data.
The smrp protocol appletalk command configures SMRP support over an AppleTalk network on an interface basis. Before you use this command, you must issue the smrp routing command to enable SMRP. After you enable SMRP, you can use this command to make SMRP services available over AppleTalk for any number of individual interfaces.
We recommend that you do not specify an SMRP network range for the AppleTalk network. Because the upper limit of the AppleTalk network range is 65535, AppleTalk network numbers always fit within the SMRP network range; SMRP network numbers are 3 bytes long, whereas AppleTalk network numbers are 2 bytes long. If the AppleTalk network is a nonextended network, which is defined by a single network number, the AppleTalk network is mapped to the SMRP network range using the single number to define both ends of the range, for example, 65520-65520.
To disable SMRP services for a specific AppleTalk network, use the no form of this command. To disable SMRP services globally, that is, for all AppleTalk networks whose interfaces you have configured for SMRP support, issue the no smrp routing command.
Examples
The following example enables SMRP globally and turns on SMRP support over AppleTalk for the current interface:

Usage Guidelines
Currently SMRP services are supported over AppleTalk only. The smrp routing command enables the use of SMRP. To enable SMRP for an AppleTalk network over a specific interface, you must use the smrp protocol appletalk interface configuration command after you issue this command. The smrp routing command has no effect until you enable SMRP at the interface level.
