Syntax Description
access-list-number
Number of the access list. This is a number from 900 to 999.
deny
Denies access if the conditions are matched.
permit
Permits access if the conditions are matched.
protocol
Name or number of an IPX protocol type. This is sometimes referred to as the packet type. Table 3 in the "Usage Guidelines" section lists some IPX protocol names and numbers.
source-network
(Optional) Number of the network from which the packet is being sent. This is an eight-digit hexadecimal number that uniquely identifies a network cable segment. It can be a number in the range 1 to FFFFFFFE. A network number of -1 matches all networks.
You do not need to specify leading zeros in the network number; for example, for the network number 000000AA, you can enter AA.
.source-node
(Optional) Node on the source-network from which the packet is being sent. This is a 48-bit value represented by a dotted triplet of four-digit hexadecimal numbers (xxxx.xxxx.xxxx).
source-node-mask
(Optional) Mask to be applied to the source-node argument. This is a 48-bit value represented as a dotted triplet of four-digit hexadecimal numbers (xxxx.xxxx.xxxx). Place ones in the bit positions you want to mask.
source-network-mask.
(Optional) Mask to be applied to the source-network argument. This is an eight-digit hexadecimal mask. Place ones in the bit positions you want to mask.
The mask must immediately be followed by a period, which must in turn immediately be followed by the source-node-mask argument.
source-socket
(Optional) Socket name or number (hexadecimal) from which the packet is being sent. Table 4 in the "Usage Guidelines" section lists some IPX socket names and numbers.
destination.network
(Optional) Number of the network to which the packet is being sent. This is an eight-digit hexadecimal number that uniquely identifies a network cable segment. It can be a number in the range 1 to FFFFFFFE. A network number of -1 matches all networks.

Usage Guidelines
Extended IPX access lists filter on protocol type. All other parameters are optional.
If a network mask is used, all other fields are required.
Use the dipx access-group command to assign an access list to an interface. You can apply only one extended or one standard access list to an interface. The access list filters all outgoing packets on the interface.
Note
Table 3 lists some IPX protocol names and numbers. Table 4 lists some IPX socket names and numbers. For additional information about IPX protocol numbers and socket numbers, contact Novell.
To delete an extended 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 protocol, use the following command:
no access-list access-list-number {deny | permit} protocol
Examples
The following example denies access to all RIP packets from the RIP process socket on source network 1 that are destined for the RIP process socket on network 2. It permits all other traffic. This example uses protocol and socket names rather than hexadecimal numbers.
access-list 900 deny -1 1 rip 2 ripaccess-list 900 permit -1The following example permits type 2 packets from any socket from host 10.0000.0C01.5234 to access any sockets on any node on networks 1000 through 100F. It denies all other traffic (with an implicit deny all):

access-list (SAP filtering)
To define an access list for filtering Service Advertising Protocol (SAP) requests, use the SAP filtering form of the access-list command in global configuration mode. To remove the access list, use the no form of this command.
access-list access-list-number {deny | permit} network[.node] [network-mask.node-mask] [service-type [server-name]]
no access-list access-list-number {deny | permit} network[.node] [network-mask.node-mask] [service-type [server-name]]
Syntax Description
access-list-number
Number of the SAP access list. This is a number from 1000 to 1099.
deny
Denies access if the conditions are matched.
permit
Permits access if the conditions are matched.
network
Network number. This is an eight-digit hexadecimal number that uniquely identifies a network cable segment. It can be a number in the range 1 to FFFFFFFE. A network number of -1 matches all networks.
You do not need to specify leading zeros in the network number. For example, for the network number 000000AA, you can enter AA.
.node
(Optional) Node specified on the network. This is a 48-bit value represented by a dotted triplet of four-digit hexadecimal numbers (xxxx.xxxx.xxxx).
network-mask.node-mask
(Optional) Mask to be applied to network and node. Place ones in the bit positions to be masked.
service-type
(Optional) Service type on which to filter. This is a hexadecimal number. A value of 0 means all services.
Table 5 in the "Usage Guidelines" section lists examples of service types.
server-name
(Optional) Name of the server providing the specified service type. This can be any contiguous string of printable ASCII characters. Use double quotation marks (" ") to enclose strings containing embedded spaces. You can use an asterisk (*) at the end of the name as a wildcard to match one or more trailing characters.
Defaults
No access lists are predefined.
Command Modes

Command History
Usage Guidelines
When configuring SAP filters for NetWare 3.11 and later servers, use the server's internal network and node number (the node number is always 0000.0000.0001) as its address in the access-list command. Do not use the network.node address of the particular interface board.
Table 5 lists some sample IPX SAP types. For more information about SAP types, contact Novell. Note that in the filter (specified by the service-type argument), we define a value of 0 to filter all SAP services. If, however, you receive a SAP packet with a SAP type of 0, this indicates an unknown service.
To delete a SAP 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
Examples
The following access list blocks all access to a file server (service Type 4) on the directly attached network by resources on other Novell networks, but allows access to all other available services on the interface:
access-list 1001 deny -1 4access-list 1001 permit -1Related Commands
clear ipx accounting
To delete all entries in the accounting database when IPX accounting is enabled, use the clear ipx accounting command in EXEC mode.
clear ipx accounting [checkpoint]
Syntax Description
Command Modes
EXEC
Command History
Usage Guidelines
Specifying the clear ipx accounting command with no keywords copies the active database to the checkpoint database and clears all entries in the active database. When cleared, active database entries and static entries, such as those set by the ipx accounting-list command, are reset to zero. Dynamically found entries are deleted.
Any traffic that traverses the router after you issue the clear ipx accounting command is saved in the active database. Accounting information in the checkpoint database at that time reflects traffic prior to the most recent clear ipx accounting command.
You can also delete all entries in the active and checkpoint database by issuing the clear ipx accounting command twice in succession.
Examples
The following example first displays the contents of the active database before the contents are cleared. Then, the clear ipx accounting command clears all entries in the active database. As a result, the show ipx accounting command shows that there is no accounting information in the active database. Lastly, the show ipx accounting checkpoint command shows that the contents of the active database were copied to the checkpoint database when the clear ipx accounting command was issued.

dipx access-group
To apply generic input and output filters to an interface, use the ipx access-group command in interface configuration mode. To remove filters, use the no form of this command.

no ipx access-group {access-list-number | name} [in | out]
Syntax Description
Defaults
No filters are predefined.
Command Modes
Interface configuration
Command History
Usage Guidelines
Generic filters control which data packets an interface receives or sends out based on the packet source and destination addresses, IPX protocol type, and source and destination socket numbers. You use the standard access-list and extended access-list commands to specify the filtering conditions.
You can apply only one input filter and one output filter per interface or subinterface.
When you do not specify an input (in) or output (out) filter in the command line, the default is an output filter.
You cannot configure an output filter on an interface where autonomous switching is already configured. Similarly, you cannot configure autonomous switching on an interface where an output filter is already present. You cannot configure an input filter on an interface if autonomous switching is already configured on any interface. Likewise, you cannot configure input filters if autonomous switching is already enabled on any interface.
Examples
The following example applies access list 801 to Ethernet interface 1. Because the command line does not specify an input filter or output filter with the keywords in or out, the software assumes that it is an output filter.
interface ethernet 1ipx access-group 801The following example applies access list 901 to Ethernet interface 0. The access list is an input filter access list as specified by the keyword in.
interface ethernet 0ipx access-group 901 inTo remove the input access list filter in the previous example, you must specify the in keyword when you use the no form of the command. The following example correctly removes the access list:

ipx accounting
To enable IPX accounting, use the ipx accounting command in interface configuration mode. To disable IPX accounting, use the no form of this command.
ipx accounting

Syntax Description
This command has no arguments or keywords.
Defaults
Disabled
Command Modes
Interface configuration
Command History
Usage Guidelines
IPX accounting allows you to collect information about IPX packets and the number of bytes that are switched through the Cisco IOS software. You collect information based on the source and destination IPX address. IPX accounting tracks only IPX traffic that is routed out an interface on which IPX accounting is configured; it does not track traffic generated by or terminated at the router itself.
The Cisco IOS software maintains two accounting databases: an active database and a checkpoint database. The active database contains accounting data tracked until the database is cleared. When the active database is cleared, its contents are copied to the checkpoint database. Using these two databases together allows you to monitor both current traffic and traffic that has previously traversed the router.
IPX accounting statistics will be accurate even if IPX access lists are being used or if IPX fast switching is enabled. Enabling IPX accounting significantly decreases performance of a fast switched interface.
IPX accounting does not keep statistics if autonomous switching is enabled. In fact, IPX accounting is disabled if autonomous or SSE switching is enabled.
Examples
The following example enables IPX accounting on Ethernet interface 0:
interface ethernet 0ipx accountingRelated Commands
ipx ipxwan
To enable the IPX wide-area network (IPXWAN) protocol on a serial interface, use the ipx ipxwan command in interface configuration mode. To disable the IPXWAN protocol, use the no form of this command.

•
•
Usage Guidelines
If you omit all optional arguments and keywords, the ipx ipxwan command defaults to ipx ipxwan 0 unnumbered router-name (which is equivalent to ipx ipxwan 0 local-server-name), where router-name is the name of the router as configured with the hostname global configuration command. For this configuration, the show ipx interface command displays
ipx ipxwan 0 0local-server-name.If you enter a value of 0 for the network-number argument, the output of the show running-config EXEC command does not show the 0 but rather reports this value as "unnumbered."
The name of each device on each side of the link must be different.
IPXWAN is a start-up end-to-end options negotiations protocol. When a link comes up, the first IPX packets sent across are IPXWAN packets negotiating the options for the link. When the IPXWAN options have been successfully determined, normal IPX traffic starts. The three options negotiated are the link IPX network number, internal network number, and link delay (ticks) characteristics. The side of the link with the higher local-node number (internal network number) gives the IPX network number and delay to use for the link to the other side. Once IPXWAN finishes, no IPXWAN packets are sent unless link characteristics change or the connection fails. For example, if the IPX delay is changed from the default setting, an IPXWAN restart will be forced.
To enable the IPXWAN protocol on a serial interface, you must not have configured an IPX network number (using the ipx network interface configuration command) on that interface.
To control the delay on a link, use the ipx delay interface configuration command. If you issue this command when the serial link is already up, the state of the link will be reset and renegotiated.
Examples
The following example enables IPXWAN on serial interface 0:
interface serial 0encapsulation pppipx ipxwanThe following example enables IPXWAN on serial interface 1 on device CHICAGO-AS. When the link comes up, CHICAGO-AS will be the master because it has a larger internal network number. It will give the IPX number 100 to NYC-AS to use as the network number for the link. The link delay, in ticks, will be determined by the exchange of packets between the two access servers.

Syntax Description
This command has no arguments or keywords.
Defaults
Fast switching is enabled.
Command Modes
Interface configuration
Command History
Usage Guidelines
Fast switching allows higher throughput by switching packets using a cache created by previous transit packets. Fast switching is enabled by default on all interfaces that support fast switching, including Token Ring, Frame Relay, PPP, Switched Multimegabit Data Service (SMDS), and ATM.
On ciscoBus-2 interface cards, fast switching is done between all encapsulation types. On other interface cards, fast switching is done in all cases except the following: transfer of packets with sap encapsulation from an Ethernet, a Token Ring, or an FDDI network to a standard serial line.
You might want to disable fast switching in two situations. One is if you want to save memory on the interface cards: fast-switching caches require more memory than those used for standard switching. The second situation is to avoid congestion on interface cards when a high-bandwidth interface is writing large amounts of information to a low-bandwidth interface.

ipx accounting-list
To filter networks for which IPX accounting information is kept, use the ipx accounting-list command in global configuration mode. To remove the filter, use the no form of this command.
ipx accounting-list number mask
no ipx accounting-list number mask
Syntax Description
Defaults
No filters are predefined.
Command Modes
Global configuration
Command History
Usage Guidelines
The source and destination addresses of each IPX packet traversing the router are compared with the network numbers in the filter. If there is a match, accounting information about the IPX packet is entered into the active accounting database. If there is no match, the IPX packet is considered to be a transit packet and may be counted, depending on the setting of the ipx accounting-transits global configuration command.
Examples
The following example adds all networks with IPX network numbers beginning with 1 to the list of networks for which accounting information is kept:
ipx accounting-list 1 0000.0000.0000Related Commands
ipx accounting-threshold
To set the maximum number of accounting database entries, use the ipx accounting-threshold command in global configuration mode. To restore the default, use the no form of this command.

no ipx accounting-threshold threshold
Syntax Description
threshold
Maximum number of entries (source and destination address pairs) that the Cisco IOS software can accumulate.
Defaults
512 entries
Command Modes
Global configuration
Command History
Usage Guidelines
The accounting threshold defines the maximum number of entries (source and destination address pairs) that the software accumulates. The threshold is designed to prevent IPX accounting from consuming all available free memory. This level of memory consumption could occur in a router that is switching traffic for many hosts. To determine whether overflows have occurred, use the show ipx accounting EXEC command.
Examples
The following example sets the IPX accounting database threshold to 500 entries:
ipx accounting-threshold 500Related Commands
ipx accounting-transits
To set the maximum number of transit entries that will be stored in the IPX accounting database, use the ipx accounting-transits command in global configuration mode. To disable this function, use the no form of this command.

no ipx accounting-transits
Syntax Description
Defaults
0 entries
Command Modes
Global configuration
Command History
Usage Guidelines
Transit entries are those that do not match any of the networks specified by ipx accounting-list global configuration commands. If you have not defined networks with ipx accounting-list commands, IPX accounting tracks all traffic through the interface (all transit entries) up to the accounting threshold limit.
Examples
The following example specifies a maximum of 100 transit records to be stored in the IPX accounting database:
ipx accounting-transits 100Related Commands
ipx advertise-default-route-only (RIP)
To advertise only the default RIP route via the specified network, use the ipx advertise-default-route-only command in interface configuration mode. To advertise all known RIP routes out the interface, use the no form of this command.
ipx advertise-default-route-only network
no ipx advertise-default-route-only network
Syntax Description
Defaults
All known routes are advertised out the interface.
Command Modes
Interface configuration
Command History
Usage Guidelines
If you specify the ipx advertise-default-route-only command, only a known default RIP route is advertised out the interface; no other networks will be advertised. If you have a large number of routes in the routing table, for example, on the order of 1000 routes, none of them will be advertised out the interface. However, if the default route is known, it will be advertised. Nodes on the interface can still reach any of the 1000 networks via the default route.
Specifying the ipx advertise-default-route-only command results in a significant reduction in CPU processing overhead when there are many routes and many interfaces. It also reduces the load on downstream routers.
This command applies only to RIP. Enhanced IGRP is not affected when you enable this command. It continues to advertise all routes that it knows about.

The following example enables the advertising of the default route only:
interface ethernet 1ipx network 1234ipx advertise-default-route-only 1234Related Commands
ipx default-route
Forwards to the default network all packets for which a route to the destination network is unknown.
ipx advertise-to-lost-route
To enable the sending of lost route mechanism packets, use the ipx advertise-to-lost-route command in global configuration mode. To disable the flooding of network down notifications that are not part of the Novell lost route algorithm, use the no form of this command.
ipx advertise-to-lost-route
no ipx advertise-to-lost-route
Syntax Description
This command has no arguments or keywords.
Defaults
Enabled

Usage Guidelines
You may reduce congestion on slow WAN links when there are many changes in an unstable network by turning off part of the Novell lost route algorithm. To turn off part of the Novell lost route algorithm, use the no ipx advertise-to-lost-route command.
Note
Examples
The following example enables the Novell lost route algorithm:
ipx advertise-to-lost-routeipx backup-server-query-interval (EIGRP)
To change the time between successive queries of each Enhanced Interior Gateway Routing Protocol (EIGRP) neighbor's backup server table, use the ipx backup-server-query-interval command in global configuration mode. To restore the default time, use the no form of this command.
ipx backup-server-query-interval interval
no ipx backup-server-query-interval
Syntax Description
interval
Minimum time, in seconds, between successive queries of each Enhanced IGRP neighbor's backup server table. The default is 15 seconds.
Defaults
15 seconds
Command Modes
Global configuration
Command History
Usage Guidelines
A lower interval may use more CPU resources, but may cause lost server information to be retrieved from other servers' tables sooner.
Examples
The following example changes the server query time to 5 seconds:
ipx backup-server-query-interval 5ipx bandwidth-percent eigrp
To configure the percentage of bandwidth that may be used by Enhanced Interior Gateway Routing Protocol (EIGRP) on an interface, use the ipx bandwidth-percent eigrp command in interface configuration mode. To restore the default value, use the no form of this command.
ipx bandwidth-percent eigrp as-number percent
no ipx bandwidth-percent eigrp as-number
Syntax Description
Defaults
50 percent
Command Modes
Interface configuration
Command History
Usage Guidelines
Enhanced IGRP will use up to 50 percent of the bandwidth of a link, as defined by the bandwidth interface configuration command. This command may be used if some other fraction of the bandwidth is desired. Note that values greater than 100 percent may be configured; this may be useful if the bandwidth is set artificially low for other reasons.
Examples
The following example allows Enhanced IGRP to use up to 75 percent (42 kbps) of a 56-kbps serial link in autonomous system 209:
interface serial 0bandwidth 56ipx bandwidth-percent eigrp 209 75Related Commands
bandwidth (interface)
Sets a bandwidth value for an interface.
ipx router
Specifies the routing protocol to use.
ipx broadcast-fastswitching
To enable the router to fast switch IPX directed broadcast packets, use the ipx broadcast-fastswitching command in global configuration mode. To disable fast switching of IPX directed broadcast packets, use the no form of this command.
ipx broadcast-fastswitching
no ipx broadcast-fastswitching
Syntax Description
This command has no arguments or keywords.
Defaults
Disabled.
The default behavior is to process switch directed broadcast packets.
Command Modes
Global configuration
Command History
Usage Guidelines
A directed broadcast is one with a network layer destination address of the form net.ffff.ffff.ffff. The ipx broadcast-fastswitching command permits the router to fast switch IPX directed broadcast packets. This may be useful in certain broadcast-based applications that rely on helpering.
Note that the router never uses autonomous switching for eligible directed broadcast packets, even if autonomous switching is enabled on the output interface. Also note that routing and service updates are always exempt from this treatment.
Examples
The following example enables the router to fast switch IPX directed broadcast packets:
ipx broadcast-fastswitching
