ipx default-output-rip-delay
To set the default interpacket delay for RIP updates sent on all interfaces, use the ipx default-output-rip-delay command in global configuration mode. To return to the initial default delay value, use the no form of this command.
ipx default-output-rip-delay delay
no ipx default-output-rip-delay
Syntax Description
delay
Delay, in milliseconds (ms), between packets in a multiple-packet RIP update. The default delay is 55 ms. Novell recommends a delay of 55 ms.
Defaults
55 ms
Command Modes
Global configuration
Command History
Usage Guidelines
The interpacket delay is the delay between the individual packets sent in a multiple-packet routing update. The ipx default-output-rip-delay command sets a default interpacket delay for all interfaces.
The system uses the delay specified by the ipx default-output-rip-delay command for periodic and triggered routing updates when no delay is set for periodic and triggered routing updates on an interface. When you set a delay for triggered routing updates, the system uses the delay specified by the ipx default-output-rip-delay command for only the periodic routing updates sent on all interfaces.
To set a delay for triggered routing updates, see the ipx triggered-rip-delay or ipx default-triggered-rip-delay commands.
Novell recommends a delay of 55 ms for compatibility with older and slower IPX machines. These machines may lose RIP updates because they process packets more slowly than the router sends them. The delay imposed by this command forces the router to pace its output to the slower-processing needs of these IPX machines.
The default delay on a NetWare 3.11 server is about 100 ms.
This command is also useful on limited bandwidth point-to-point links or X.25 and Frame Relay multipoint interfaces.
Examples
The following example sets a default interpacket delay of 55 ms for RIP updates sent on all interfaces:

Usage Guidelines
The interpacket delay is the delay between the individual packets sent in a multiple-packet routing update. A triggered routing update is one that the system sends in response to a "trigger" event, such as a request packet, interface up/down, route up/down, or server up/down.
The ipx default-triggered-rip-delay command sets the default interpacket delay for triggered routing updates sent on all interfaces. On a single interface, you can override this global default delay for triggered routing updates using the ipx triggered-rip-delay interface command.
The global default delay for triggered routing updates overrides the delay value set by the ipx output-rip-delay or ipx broadcast-fastswitching command for triggered routing updates.
If the delay value set by the ipx output-rip-delay or ipx broadcast-fastswitching command is high, then we strongly recommend a low delay value for triggered routing updates so that updates triggered by special events are sent in a more timely manner than periodic routing updates.
Novell recommends a delay of 55 ms for compatibility with older and slower IPX machines. These machines may lose RIP updates because they process packets more slowly than the router sends them. The delay imposed by this command forces the router to pace its output to the slower-processing needs of these IPX machines.
The default delay on a NetWare 3.11 server is approximately 100 ms.
When you do not set the interpacket delay for triggered routing updates, the system uses the delay specified by the ipx output-rip-delay or ipx broadcast-fastswitching command for both periodic and triggered routing updates.
When you use the no form of the ipx default-triggered-rip-delay command, the system uses the delay set by the ipx output-rip-delay or ipx broadcast-fastswitching command for triggered RIP updates, if set. Otherwise, the system uses the initial default delay as described in the "Defaults" section.
This command is also useful on limited bandwidth point-to-point links, or X.25 and Frame Relay multipoint interfaces.

ipx delay
To set the tick count, use the ipx delay command in interface configuration mode. To reset the default increment in the delay field, use the no form of this command.
ipx delay ticks
no ipx delay
Syntax Description
ticks
Number of IBM clock ticks of delay to use. One clock tick is 1/18 of a second (approximately 55 ms).
Defaults
The IPX default delay is determined from the interface delay configured on the interface with the delay command. It is (interface delay + 333) / 334. Therefore, unless you change the delay by a value greater than 334, you will not notice a difference.
Command Modes
Interface configuration
Command History
Usage Guidelines
The ipx delay command sets the count used in the IPX RIP delay field, which is also known as the ticks field.
IPXWAN links determine their delay dynamically. If you do not specify the ipx delay command on an interface and you have not changed the interface delays with the interface delay interface configuration command, all LAN interfaces have a delay of 1 and all WAN interfaces have a delay of 6. The preferred method of adjusting delays is to use the ipx delay command, not the interface delay command. The show ipx interface EXEC command display only the delay value configured with the ipx delay command.
With IPXWAN, if you change the interface delay with the interface delay command, the ipx delay command uses that delay when calculating a delay to use. Also, when changing delays with IPXWAN, the changes affect only the link's calculated delay on the side considered to be the master.
Leaving the delay at its default value is sufficient for most interfaces.
Examples
The following example changes the delay for serial interface 0 to 10 ticks:

Syntax Description
Defaults

Command Modes
Interface configuration
Command History
Usage Guidelines
The ipx down command administratively shuts down the specified network. The network still exists in the configuration, but is not active. When shutting down, the network sends out update packets informing its neighbors that it is shutting down. This allows the neighboring systems to update their routing, SAP, and other tables without having to wait for routes and services learned via this network to time out.
To shut down an interface in a manner that is considerate of one's neighbor, use ipx down before using the shutdown command.
Examples
The following example administratively shuts down network AA on Ethernet interface 0:
interface ethernet 0 ipx down AAipx eigrp-sap-split-horizon
To configure Enhanced Interior Gateway Routing Protocol (EIGRP) SAP split horizon, use the ipx eigrp-sap-split-horizon command in global configuration mode. To revert to the default, use the no form of this command.
ipx eigrp-sap-split-horizon
no ipx eigrp-sap-split-horizon
Syntax Description
This command has no argument or keywords.
Defaults
Enabled on LANs and disabled on WANs.
Command Modes
Global configuration
Command History
Usage Guidelines
When split horizon is enabled, Enhanced IGRP SAP update and packets are not sent back to the same interface where the SAP is received from. This reduces the number of Enhanced IGRP packets on the network.
Split horizon blocks information about SAPs from being advertised by a router about any interface from which that information originated. Typically, this behavior 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.
Note
When the ipx sap-incremental split-horizon interface configuration command is configured, it takes precedence over the ipx eigrp-sap-split-horizon command.
Examples
The following example disables split horizon on the router:
no ipx eigrp-sap-split-horizonRelated Commands
ipx encapsulation
To set the Ethernet frame type of the interface to that of the local file server, use the ipx encapsulation command in interface configuration mode. To reset the frame type to the default, use the no form of this command.
ipx encapsulation encapsulation-type
no ipx encapsulation encapsulation-type
Syntax Description
encapsulation-type
(Required) Type of encapsulation (framing). For a list of possible encapsulation types, see Table 48.
Table 48 describes the types of encapsulation available for specific interfaces.
Defaults
novell-ether
Command Modes
Interface configuration
Command History
Usage Guidelines
You can configure an IPX network on any supported interface as long as all the networks on the same physical interface use a distinct encapsulation type. For example, you can configure up to four IPX networks on a single Ethernet cable because Ethernet supports four encapsulation types.
The interface processes only packets with the correct encapsulation and the correct network number. IPX networks that use other encapsulations can be present on the physical network. The only effect on the router is that it uses some processing time to examine packets to determine whether they have the correct encapsulation.
Note
To determine the frame type of the server, use the config command at the prompt of the local server.
Examples
The following example sets the frame type to Novell Ethernet II:

Usage Guidelines
Using the ipx flooding-unthrottled command may result in excessive NLSP traffic, causing network congestion. You can configure the router to throttle NLSP packets by using the no ipx flooding-unthrottled command.
Examples
The following example applies the default setting for unthrottled NLSP packets:

no ipx gns-response-delay
Syntax Description
Defaults
0 (no delay)
Command Modes
Global configuration (globally changes the delay for the router)
Interface configuration (overrides the globally configured delay for an interface)Command History
Usage Guidelines
This command can be used in two modes: global configuration or interface configuration. In both modes, the command syntax is the same. A delay in responding to GNS requests might be imposed so that, in certain topologies, any local Novell IPX servers respond to the GNS requests before our software does. It is desirable to have these end-host server systems get their reply to the client before the router does because the client typically takes the first response, not the best response. In this case the best response is the one from the local server.
NetWare 2.x has a problem with dual-connected servers in parallel with a router. If you are using this version of NetWare, you should set a GNS delay. A value of 500 ms is recommended.
In situations in which servers are always located across routers from their clients, there is no need for a delay to be imposed.
Examples
The following example sets the delay in responding to GNS requests to 500 ms (0.5 seconds):
ipx gns-response-delay 500Related Commands
Disables the sending of replies to IPX GNS queries.
ipx rip-response-delay
Changes the delay when responding to RIP requests.
ipx gns-round-robin
To rotate using a round-robin selection method through a set of eligible servers when responding to Get Nearest Server (GNS) requests, use the ipx gns-round-robin command in global configuration mode. To use the most recently learned server, use the no form of this command.
ipx gns-round-robin
no ipx gns-round-robin
Syntax Description
This command has no arguments or keywords.
Defaults
The most recently learned eligible server is used.
Command Modes
Global configuration
Command History
Usage Guidelines
In the normal server selection process, requests for service are responded to with the most recently learned, closest server. If you enable the round-robin method, the Cisco IOS software maintains a list of the nearest servers eligible to provide specific services. It uses this list when responding to GNS requests. Responses to requests are distributed in a round-robin fashion across all active IPX interfaces on the router.
Eligible servers are those that satisfy the "nearest" requirement for a given request and that are not filtered either by a SAP filter or by a GNS filter.
Examples
The following example responds to GNS requests using a round-robin selection method from a list of eligible nearest servers:

ipx hello-interval eigrp
To configure the interval between Enhanced Interior Gateway Routing Protocol (EIGRP) hello packets, use the ipx hello-interval eigrp command in interface configuration mode. To restore the default interval, use the no form of this command.

no ipx hello-interval eigrp autonomous-system-number seconds
Syntax Description
Defaults
For low-speed NBMA networks: 60 seconds
For all other networks: 5 secondsCommand Modes
Interface configuration
Command History
Usage Guidelines
The default of 60 seconds 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. 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.
Examples
The following example changes the hello interval to 10 seconds:

Specifies the length of time a lost Enhanced IGRP route is placed in the hold-down state.
ipx helper-address
To forward broadcast packets to a specified server, use the ipx helper-address command in interface configuration mode. To disable this function, use the no form of this command.
ipx helper-address network.node
no ipx helper-address network.node
Syntax Description
Defaults
Disabled
Command Modes
Interface configuration
Command History
Usage Guidelines
Routers normally block all broadcast requests and do not forward them to other network segments. This is done to prevent the degradation of performance over the entire network. The ipx helper-address command allows broadcasts to be forwarded to other networks. This is useful when a network segment does not have an end-host capable of servicing a particular type of broadcast request. This command lets you forward the broadcasts to a server, network, or networks that can process them. Incoming unrecognized broadcast packets that match the access list created with the ipx helper-list command, if it is present, are forwarded.
You can specify multiple ipx helper-address commands on a given interface.
The Cisco IOS software supports all-networks flooded broadcasts (sometimes referred to as all-nets flooding). These are broadcast messages that are forwarded to all networks. To configure the all-nets flooding, define the IPX helper address for an interface as follows:
ipx helper-address -1.FFFF.FFFF.FFFFOn systems configured for IPX routing, this helper address is displayed as follows (via the show ipx interface command):
FFFFFFFF.FFFF.FFFF.FFFFAlthough our software takes care to keep broadcast traffic to a minimum, some duplication is unavoidable. When loops exist, all-nets flooding can propagate bursts of excess traffic that will eventually age out when the hop count reaches its limit (16 hops). Use all-nets flooding carefully and only when necessary. Note that you can apply additional restrictions by defining a helper list.
To forward type 20 packets to only those nodes specified by the ipx helper-address command, use the ipx helper-address command in conjunction with the ipx type-20-helpered global configuration command.
To forward type 20 packets to all nodes on the network, use the ipx type-20-propagation command. See the ipx type-20-propagation command for more information.
Examples
The following example forwards all-nets broadcasts on Ethernet interface 0 (except type 20 propagation packets) are forwarded to IPX server 00b4.23cd.110a on network bb:
interface ethernet 0 ipx helper-address bb.00b4.23cd.110aRelated Commands
ipx helper-list
To assign an access list to an interface to control broadcast traffic (including type 20 propagation packets), use the ipx helper-list command in interface configuration mode. To remove the access list from an interface, use the no form of this command.
ipx helper-list {access-list-number | name}
no ipx helper-list {access-list-number | name}
Syntax Description
Defaults
No access list is preassigned.
Command Modes
Interface configuration
Command History
Usage Guidelines
The ipx helper-list command specifies an access list to use in forwarding broadcast packets. One use of this command is to prevent client nodes from discovering services they should not use.
Because the destination address of a broadcast packet is by definition the broadcast address, this command is useful only for filtering based on the source address of the broadcast packet.
The helper list, if present, is applied to both all-nets broadcast packets and type 20 propagation packets.
The helper list on the input interface is applied to packets before they are output via either the helper address or type 20 propagation packet mechanism.
Examples
The following example assigns access list 900 to Ethernet interface 0 to control broadcast traffic:
interface ethernet 0ipx helper-list 900Related Commands
ipx hold-down eigrp
To specify the length of time a lost Enhanced Interior Gateway Routing Protocol (EIGRP) route is placed in the hold-down state, use the ipx hold-down eigrp command in interface configuration mode. To restore the default time, use the no form of this command.
ipx hold-down eigrp autonomous-system-number seconds
no ipx hold-down eigrp autonomous-system-number seconds
Syntax Description
autonomous-system-number
Enhanced IGRP autonomous system number. It can be a number from 1 to 65,535.
seconds
Hold-down time, in seconds. The default hold time is 5 seconds.
Defaults
5 seconds
Command Modes
Interface configuration
Command History
Usage Guidelines
When an Enhanced IGRP route is lost, it is placed into a hold-down state for a period of time. The purpose of the hold-down state is to ensure the validity of any new routes for the same destination.
The amount of time a lost Enhanced IGRP route is placed in the hold-down state is configurable. Set the amount of time to a value longer than the default of 5 seconds if your network requires a longer time for the unreachable route information to propagate.
Examples
The following example changes the hold-down time for autonomous system from 4 to 45 seconds:
interface ethernet 0ipx network 10ipx hold-down eigrp 4 45ipx hold-time eigrp
To specify the length of time for which a neighbor should consider Enhanced IGRP hello packets valid, use the ipx hold-time eigrp command in interface configuration mode. To restore the default time, use the no form of this command.
ipx hold-time eigrp autonomous-system-number seconds
no ipx hold-time eigrp autonomous-system-number seconds
Syntax Description
Defaults
For low-speed nonbroadcast, multiaccess (NBMA) networks: 180 seconds
For all other networks: 15 secondsCommand Modes
Interface configuration
Command History
Usage Guidelines
If the current value for the hold time is less than two times the interval between hello packets, the hold time will be reset to three times the hello interval.
If a router does not receive a hello packet within the specified hold time, routes through the router are considered available.
Increasing the hold time delays route convergence across the network.
The default of 180 seconds 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.
Examples
The following example changes the hold time to 45 seconds:
interface ethernet 0ipx network 10ipx hold-time eigrp 4 45Related Commands
ipx input-network-filter (RIP)
To control which networks are added to the Cisco IOS software routing table, use the ipx input-network-filter command in interface configuration mode. To remove the filter from the interface, use the no form of this command.

no ipx input-network-filter {access-list-number | name}
Syntax Description
Defaults
No filters are predefined.
Command Modes

Command History
Usage Guidelines
The ipx input-network-filter command controls which networks are added to the routing table based on the networks learned in incoming IPX routing updates (RIP updates) on the interface.
You can issue only one ipx input-network-filter command on each interface.
Examples
In the following example, access list 876 controls which networks are added to the routing table when IPX routing updates are received on Ethernet interface 1. Routing updates for network 1b will be accepted. Routing updates for all other networks are implicitly denied and are not added to the routing table.
