Table 11 show appletalk arp Field Descriptions 

Field
Description

Address

AppleTalk network address of the interface.

Age (min)

Time, in minutes, that this entry has been in the ARP table. Entries are purged after they have been in the table for 240 minutes (4 hours). A hyphen indicates that this is a new entry.

Type

Indicates how the ARP table entry was learned. It can be one of the following:

Dynamic—Entry was learned via AARP.

Hardware—Entry was learned from an adapter in the router.

Pending—Entry for a destination for which the router does not yet know the address. When a packet requests to be sent to an address for which the router does not yet have the MAC-level address, the Cisco IOS software creates an AARP entry for that AppleTalk address, then sends an AARP Resolve packet to get the MAC-level address for that node. When the software gets the response, the entry is marked "Dynamic." A pending AARP entry times out after 1 minute.

Hardware Addr

MAC address of this interface.

Encap

Encapsulation type. It can be one of the following:

ARPA—Ethernet-type encapsulation

Subnetwork Access Protocol (SNAP)—IEEE 802.3 encapsulation

Interface

Type and number of the interface.

Usage Guidelines

The information in the show appletalk macip-servers display can help you quickly determine the status of your MacIP configuration. In particular, the STATE field can help identify problems in your AppleTalk environment.

Examples

The following is sample output from the show appletalk macip-servers command:

Router# show appletalk macip-servers

MACIP SERVER 1, IP 172.18.199.221,  ZONE 'S/W Test Lab' STATE is server_up
Resource #1 DYNAMIC 172.18.199.1-172.18.199.10, 1/10 IP in use
Resource #2 STATIC 172.18.199.11-172.18.199.20, 0/10 IP in use

Table 25 describes the fields shown in the display.

Table 25 show appletalk macip-servers Field Descriptions 

Field
Description

MACIP SERVER 1

Number of the MacIP server. This number is assigned arbitrarily.

IP 172.18.199.221

IP address of the MacIP server.

ZONE `S/W Test Lab'

AppleTalk server zone specified with the appletalk macip server command.

STATE is server_up

State of the server. Table 27 lists the possible states.

If the server remains in the "resource_wait" state, check that resources have been assigned to this server with either the appletalk macip dynamic or the appletalk macip static command.

Resource #1 DYNAMIC 172.18.199.1-172.18.199.10, 1/10 IP in use

Resource specifications defined in the appletalk macip dynamic and appletalk macip static commands. This list indicates whether the resource address was assigned dynamically or statically, identifies the IP address range associated with the resource specification, and indicates the number of active MacIP clients.


Use the show appletalk macip-servers command with show appletalk interface to identify AppleTalk network problems, as follows:


Step 1 Determine the state of the MacIP server using show appletalk macip-servers. If the STATE field continues to indicate an anomalous status (something other than "server_up," such as "resource_wait" or "zone_wait"), there is a problem.

Step 2 Determine the status of AppleTalk routing and the specific interface using the show appletalk interface command.

Step 3 If the protocol and interface are up, check the MacIP configuration commands for inconsistencies in the IP address and zone.


The STATE field of the show appletalk macip-servers command indicates the current state of each configured MacIP server. Each server operates according to the finite-state machine table described in Table 26. Table 27 describes the state functions listed in Table 26. These are the states that are displayed by the show appletalk macip-servers command.

State
Description

ck_resource

The server verifies that at least one client range is available. If not, it deregisters NBP names and returns to the resource_wait state.

del_server

State at which all servers end. In this state, the server deregisters all NBP names, purges all clients, and deallocates server resources.

initial

The state at which all servers start.

resource-wait

The server waits until a client range for the server has been configured.

send_confirms

The server tickles active clients every minute, deletes clients that have not responded within the last 5 minutes, and checks IP and AppleTalk interfaces used by MacIP server. If the interfaces are down or have been reconfigured, the server restarts.

server_start

The server registers configured IPADDRESS and registers as IPGATEWAY. It then opens an ATP socket to listen for IP address assignment requests, sends NBP lookup requests for existing IPADDRESSes, and automatically adds clients with addresses within one of the configured client ranges.

server_up

The server has registered. Being in this state enables routing to client ranges. The server now responds to IP address assignment requests.

zone_wait

The server waits until the configured AppleTalk zone name for the server is up. The server will remain in this state if no such zone has been configured or if AppleTalk routing is not enabled.

*

An asterisk in the first column represents any state. An asterisk in the second column represents a return to the previous state.

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@Marketing

Registering 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.

Examples

The following is sample output from the show appletalk nbp command:

Router# show appletalk nbp

Net  Adr Skt Name                    Type            Zone

Depending on the configuration of the appletalk lookup-type and appletalk name-lookup-interval global configuration commands, a node name may appear in this display instead of a node address.

Table 34 show appletalk route Field Descriptions 

Field
Description

Codes:

Codes defining how the route was learned.

    R - RTMP derived

Route learned from an RTMP update.

    C - Connected

Directly connected network.

    A - AURP

Route learned from an AURP update.

    S - Static

Statically defined route.

    P - Proxy

Proxy route. 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 internetwork, 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.

routes

Number of routes in the table.

Net

Network to which the route goes.

Net 999-999

Cable range to which the route goes.

directly connected

Indicates that the network is directly connected to the router.

uses

Fair estimate of the number of times a route gets used. It actually indicates the number of times the route has been selected for use prior to operations such as access list filtering.

Ethernet

Possible interface through which updates to the remote network will be sent.

zone

Name of zone of which the destination network is a member.

[1/G]

Number of hops to this network, followed by the state of the link to that network. The state can be one of the following letters:

G—Link is good.

S—Link is suspect.

B—Link is bad.

The state is determined from the routing updates that occur at 10-second intervals. A separate and nonsynchronized event occurs at 20-second intervals, checking and flushing the ratings for particular routes that have not been updated. For each 20-second period that passes with no new routing information, a rating changes from G to S and then from S to B. After 1 minute with no updates, that route is flushed. Every time the Cisco IOS software receives a useful update, the status of the route in question is reset to G. Useful updates are those advertising a route that is as good or better than the one currently in the table.

When an AppleTalk route is poisoned by another router, its metric gets changed to poisoned (that is, 31 hops). The software then will age this route normally during a holddown period, during which the route will still be visible in the routing table.

via 258.179

Address of a router that is the next hop to the remote network.

via gatekeeper

Node name of a router that is the next hop to the remote network.

sec

Number of seconds that have elapsed since an RMTP update about this network was last received.


The following is sample output from the show appletalk route command when you specify a network number:

Router# show appletalk route 69

Codes: R - RTMP derived, C - connected, A - AURP 
P - proxy, S - static

The first zone listed for each entry is its default (primary) zone.

R Net 69-69 [2/G] via gatekeeper, 0 sec, Ethernet0, zone Empty Guf
Route installed 125:20:21, updated 0 secs ago
Next hop: gatekeeper, 2 hops away
Zone list provided by gatekeeper
Route has been updated since last RTMP was sent
Valid zones: "Empty Guf"

routes in internet

Number of routes in the Apple Talk internet.

Net

Cable range to which the route goes. This is the number of the network you specified on the show appletalk route command line.

[2/G]

Number of hops to this network, followed by the state of the link to that network. The state can be one of the following letters:

G—Link is good.

S—Link is suspect.

B—Link is bad.

The state is determined from the routing updates that occur at 10-second intervals. A separate and nonsynchronized event occurs at 20-second intervals, checking and flushing the ratings for particular routes that have not been updated.

When an AppleTalk route is poisoned by another router, its metric gets changed to poisoned (that is, 31 hops). The software then will age this route normally during a holddown period, during which the route will still be visible in the routing table.

via gatekeeper

Address or node name of a router that is the next hop to the remote network.

0 sec

Number of seconds that have elapsed since an RMTP update about this network was last received.

Ethernet0

Possible interface through which updates to the remote network will be sent.

zone Empty Guf

Name of zone of which the destination network is a member.

Route installed 125:20:21

updated 0 secs ago

Time (in seconds) since the software received an update for this route.

Next hop: gatekeeper

Address or node name of the router that is one hop away.

2 hops away

Number of hops to the network specified in the show appletalk route command line.

Zone list provided by gatekeeper

Address or node name of the router that provided the zone list included with the RTMP update.

Route has been updated since last RTMP was sent

Indicates whether the software has received a routing update from a neighboring router since the last time the software sent an RTMP update for this route.

Valid zones: "Empty Guf"

Zone names that are valid for this network.

Field
Description

Rcvd:

This section describes the packets received.

    357741 total

Total number of packets received.

    0 checksum errors

Number of packets that were discarded because their DDP checksum was incorrect. The DDP checksum is verified for packets that are directed to the router. It is not verified for forwarded packets.

    264 bad hop count

Number of packets discarded because they had traveled too many hops.

    321006 local destination

Number of packets addressed to the local router.

    0 access denied

Number of packets discarded because they were denied by an access list.

    0 for MacIP

Number of AppleTalk packets the Cisco IOS software received that were encapsulated within an IP packet.

    0 bad MacIP

Number of bad MacIP packets the software received and discarded. These packets may have been malformed or may not have included a destination address.

    0 no client

Number of packets discarded because they were directed to a nonexistent MacIP client.

    13510 port disabled

Number of packets discarded because routing was disabled for that port (extended AppleTalk only). This is the result of a configuration error or a packet's being received while the software is in verification/discovery mode.

    2437 no listener

Number of packets discarded because they were directed to a socket that had no services associated with it.

    0 ignored

Number of routing update packets ignored because they were from a misconfigured neighbor or because routing was disabled.

    0 martians

Number of packets discarded because they contained bogus information in the DDP header. What distinguishes this error from the others is that the data in the header is never valid as opposed to not being valid at a given point in time.

Bcast:

Number of broadcast packets sent and received.

    191881 received

Number of broadcast packets received.

    270406 sent

Number of broadcast packets sent.

Sent:

Number of packets generated.

    66495 forwarded

Number of packets forwarded using routes derived from process switching.

    1840 fast forwarded

Number of packets sent using routes from the fast-switching cache.

    0 loopback

Number of packets that were broadcast out an interface on the router for which the device simulated reception of the packet because the interface does not support sending a broadcast packet to itself. The count is cumulative for all interfaces on the device.

    0 forwarded from MacIP

Number of IP packets forwarded that were encapsulated within an AppleTalk DDP packet.

    0 MacIP failures

Number of MacIP packets sent that were corrupted during the MacIP encapsulation process.

    436 encapsulation failed

Number of packets the router could not send because encapsulation failed. This can happen because encapsulation of the DDP packet failed or because AARP address resolution failed.

    0 no route

Number of packets the router could not send because it knew of no route to the destination.

    0 no source

Number of packets the router sent when it did not know its own address. This should happen only if something is seriously wrong with the router or network configuration.

DDP:

This section describes DDP packets seen.

    387265 long

Number of DDP long packets.

    0 short

Number of DDP short packets.

    0 macip

Number of IP packets encapsulated in an AppleTalk DDP packet that the router sent.

Number of packets whose physical packet length and claimed length differed.

NBP:

This section describes NBP packets.

    302779 received

Total number of NBP packets received.

    0 invalid

Number of invalid NBP packets received. Causes include invalid op code and invalid packet type.

    0 proxies

Number of NBP proxy lookup requests received by the router when it was configured for NBP proxy transition usage.

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 following example is associated with two network numbers and four cable ranges.

Examples

The following is sample output from the show appletalk zone command:

Usage Guidelines

The SMRP forwarding table describes the relationship between the SMRP router and the distribution tree for each SMRP group on the internetwork. 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.


Note Because SMRP is currently supported over AppleTalk networks only, sample output resulting from the show smrp forward command is the same as output from the show smrp forward appletalk command.


Examples

The following is sample output from the show smrp forward command that shows all entries:

Router# show smrp forward

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 the 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, 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.

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.


Note Because SMRP is currently supported over AppleTalk networks only, sample output resulting from the show smrp neighbor command is the same as output from show smrp neighbor appletalk command.

Usage Guidelines

For all SMRP ports, the show smrp port command displays the interface of the SMRP port, the current state of the port, the network protocol type (currently only AppleTalk is supported) and its address, the address of the primary router on the local network, the address of the secondary router on the local network, the current groups on the port, and the last group on the port.

If the interface of a specific SMRP port is given, this information is displayed for that port only.


Note Because SMRP is currently supported over AppleTalk networks only, sample output resulting from the show smrp port command is the same as output from show smrp port appletalk command.


Examples

The following is sample output from the show smrp port command:

Router# show smrp port

Usage Guidelines

For all SMRP routes, the show smrp route command displays the number of SMRP routes in the internetwork. For each route, it shows the SMRP network range of the route, the version of the route, the elapsed time since the route was updated, the number of hops away the route is from the route's origin, the number of hops away the route is from the tunnel origin, the interface from which the route was received, and the router that sent the route.

If a specific network range is given, this information is displayed for that network range only.

If the interface is specified, the routes that came from this interface are displayed.

If the appletalk keyword is specified with or without an SMRP network range, the number of SMRP routes in the internetwork is not specified. Connected routes have a hop value of 0 and no address value.


Note Because SMRP is currently supported over AppleTalk networks only, sample output resulting from the show smrp port command is the same as output from show smrp port appletalk command.

15.0(1)M

This command was removed.


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 to fast switch SMRP data packets out the interfaces specified by the forwarding table.

SMRP fast switching requires that:

A parent port is fast-switch enabled.

One or more child ports are fast-switch enabled.

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:

A child endpoint leaves the SMRP group.

A new child endpoint joins the SMRP group.

A port's fast-switching configuration is enabled or disabled.

A port is restarted.

Examples

The following example disables SMRP fast-switching:

no smrp mroute-cache protocol appletalk

smrp protocol appletalk [network-range beginning-end]

no smrp protocol appletalk [network-range beginning-end]

Syntax Description

network-range

(Optional) SMRP network range for the interface. We recommend that you do not specify an SMRP network range. When you omit the range, the Cisco IOS software uses the AppleTalk cable range configured for the interface as the SMRP network range. If you specify a range, it must fall within the SMRP network range 1 to 65,535.

beginning-end

(Optional) The beginning and end of the SMRP network range for this AppleTalk network. If you specify a range, it must fall within the SMRP network range 1 to 65,535.

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 65,535, 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, 65,520-65,520).

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:

smrp routing
interface ethernet 0
 smrp protocol appletalk

The following example disables SMRP over AppleTalk for the current interface:

interface ethernet 0

Type ? to display the following list of test options:

Router(atalk test)# ? 
end    Exit AppleTalk test mode 
nbp    AppleTalk NBP test commands

Use the test appletalk command with the nbp options to test and to perform informational lookups of NBP-registered entities. Use the NBP options when you find that AppleTalk zones are listed in the Chooser, but services in these zones are unavailable.

Type nbp ? to learn what NBP test commands you can use:

Router(atalk test)# nbp ?
nbp confirm:         send out an NBP confirm packet to the specified entity
nbp lookup:	          lookup an NVE. prompt for name, type and zone
nbp parameters:	      display/change lookup parms (ntimes, ncecs, interval)
nbp poll: 	           for every zone, lookup all devices, using default
?:	                   print command list
end: 	                exit nbptest

The following list summarizes the nbp test commands you can use:

nbp confirm—Sends out an NBP confirm packet to the specified entity.

nbp lookup—Searches for NBP entities in a specific zone.

nbp parameters—Sets the parameters used in subsequent lookup and pool tests.

nbp poll—Searches for all devices in all zones.

?—Displays the list of nbp tests.

end—Exit from the nbp test commands.

The remainder of this section shows and explains the syntax and output of the various NBP test commands.

When running any of the NBP tests, you specify a nonprinting character by entering a three-character string that is the hexadecimal equivalent of the character. For example, type :c5 to specify the test appletalk truncation wildcard.

This is the syntax of the nbp confirm command:

nbp confirm appletalk-address [:skt] object:type@zone

The syntax description is as follows:

appletalk-address

AppleTalk network address in the form network.node. The argument network is the 16-bit network number in the range 1 to 65,279. The argument node is the 8-bit node number in the range 0 to 254. Both numbers are decimal.

:skt

(Optional) Name of socket.

object:type

Name of device and the type of service. The colon (:) between object and type is required.

@zone

Name of the AppleTalk zone where the entity object:type resides.


Examples

The following is sample output from the nbp confirm command. In this example, the test sends a confirm packet to the entity ciscoRouter in zone Engineering.

Router(atalk test)# nbp confirm 24279.173 my-mac:AFPServer@Engineering

confirmed my-mac:AFPServer@Engineering at 24279n,173a,250s

This is the syntax of the nbp lookup command:

nbp lookup object:type@zone

The syntax description is as follows:

object:type

Name of device and the type of service. The colon (:) between object and type is required.

@zone

Name of the AppleTalk zone where the entity object:type resides.


The following is sample output from the nbp lookup command:

Router(atalk test)# nbp lookup =:macintosh:c5@engineering

Number of NBP replies received.


This is the syntax of the nbp parameters command:

nbp parameters retransmissions replies interval

The syntax description is as follows

retransmissions

Maximum number of lookup retransmissions. This is a number from 1 to 5. The default value is 5.

replies

Maximum number of replies to accept for each lookup. This is a number from 1 to 500. The default is 1.

interval

Interval, in seconds, between each retry. This value is from 1 to 60 seconds. The default is 5 seconds.


:

The following is sample output of the nbp parameters command. In this example, the maximum number of retransmission is 1, the maximum number of replies is 100, and there are 10 seconds between each retry.

Router(atalk test)# nbp parameters 1 100 10

The nbp poll command has no keywords or arguments. The following is sample output from the nbp poll command:

Router(atalk test)# nbp poll

poll: sent 2 lookups
