Novell IPX Commands
Novell Internet Packet Exchange (IPX) is derived from the Xerox Network Systems (XNS) Internet Datagram Protocol (IDP). One major difference between IPX and XNS is that they do not always use the same Ethernet encapsulation format. A second difference is that IPX uses Novell's proprietary Service Advertisement Protocol (SAP) to advertise special network services.
Our implementation of Novell's IPX protocol has been certified as providing full IPX router functionality.
Note
One or more of the commands that previously appeared this chapter have been replaced by new commands. See the Router Products Command Reference publication 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.
Use the commands in this chapter to configure and monitor Novell IPX networks. For IPX configuration information and examples, refer to the "Configuring Novell IPX" chapter in the Router Products Configuration Guide.
Note
For all commands that previously had the keyword novell, this keyword has been changed to ipx. However, you can still use the keyword novell in all commands.
access-list (extended)
To define an extended Novell IPX access list, use the extended version of the access-list global configuration command. To remove an extended access list, use the no form of this command.

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 ipx 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
For some versions of NetWare, the protocol type field is not a reliable indicator of the type of packet encapsulated by the IPX header. In these cases, use the source and destination socket fields to make this determination. For additional information, contact Novell.

area-address
To define a set of network numbers to be part of the current NLSP area, use the area-address router configuration command. To remove a set of network numbers from the current NLSP area, use the no form of this command.
area-address address mask
no area-address address mask
Syntax Description
address
|
Network number prefix. This is a 32-bit hexadecimal number.
|
mask
|
Mask that defines the length of the network number prefix. This is a 32-bit hexadecimal number.
|
Default
No area address is defined by default.
Command Mode
Router configuration
Usage Guidelines
You must configure at least one area address before NLSP will operate.
The area-address command defines a prefix that includes all networks that are in the area. This prefix allows a single route to an area address to substitute for a longer list of networks.
All networks on which NLSP is enabled must fall under the area address prefix. This configuration is for future compatibility: when Level 2 NLSP becomes available, the only route advertised for the area will be the area address prefix (the prefix represents all networks within the area).
All routers in an NLSP area must be configured with a common area address, or they will form separate areas. You can configure up to three area addresses on the router.
The area address must have zero bits in all bit positions where the mask has zero bits. The mask must consist of only left-justified contiguous one bits.
Examples
The following example defines an area address that includes networks AAAABBC0 through AAAABBDF:
area-address AAAABBC0 FFFFFFE0
The following example defines an area address that includes all networks:

IPX accounting allows you to collect information about IPX packets and the number of bytes that are switched through the router. You collect information based on the source and destination IPX address. Accounting tracks only IPX traffic that is passing out of the router; it does not track traffic generated by or terminating at the router.
IPX accounting statistics will be accurate even if IPX fast switching is enabled or if IPX access lists are being used. However, IPX accounting does not keep statistics if autonomous switching is enabled.
The router software maintains two accounting databases, an active database and a checkpointed database.
Example
The following example enables IPX accounting on Ethernet interface 0:

ipx accounting-list
ipx accounting-threshold
ipx accounting-transits
show ipx accounting
ipx accounting-list
To filter the networks for which IPX accounting information is kept, use the ipx accounting-list global configuration command. To remove the filter, use the no form of this command.
ipx accounting-list number mask
no ipx accounting-list number mask
Syntax Description
number
|
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 FFFFFFFD.
You do not need to specify leading zeroes in the network number. For example, for the network number 000000AA you can enter AA.
|
mask
|
Network mask.
|
Default
No filters are predefined.
Command Mode
Global configuration
Usage Guidelines
The source and destination addresses of each IPX packet are logically ANDed with the mask and compared with the network number. If there is a match, accounting information about the IPX packet is entered into the 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.
Example
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 0000.0000.0000
Related Commands

ipx accounting
ipx accounting-threshold
ipx accounting-transits
show ipx accounting
ipx accounting-threshold
To set the maximum number of accounting database entries, use the ipx accounting-threshold global configuration command. To restore the default, use the no form of this command.
ipx accounting-threshold threshold
no ipx accounting-threshold threshold
Syntax Description
threshold
|
Maximum number of entries (source and destination address pairs) that the router can accumulate.
|
Default
512 entries
Command Mode
Global configuration
Usage Guidelines
The accounting threshold defines the maximum number of entries (source and destination address pairs) that the router 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.
Example
The following example sets the IPX accounting database threshold to 500 entries:
ipx accounting-threshold 500
Related Commands
clear ipx accounting
ipx accounting
ipx accounting-list
ipx accounting-transits
show ipx accounting
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 global configuration command. To disable this function, use the no form of this command.
ipx accounting-transits count
no ipx accounting-transits
Syntax Description
count
|
Number of transit entries that will be stored in the IPX accounting database.
|
Default
0 entries
Command Mode
Global configuration
Usage Guidelines
Transit entries are those that do not match any of the filters specified by ipx accounting-list global configuration commands. If you have not defined any filters, no transit entries are possible.
To maintain accurate accounting totals, the router software maintains two accounting databases: an active database and a checkpointed database.
Example
The following example specifies a maximum of 100 transit records to be stored in the IPX accounting database:
ipx accounting-transits 100

ipx advertise-default-route-only
To advertise only the default route via the specified network, use the
ipx advertise-default-route-only interface configuration command. To advertise all known 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
network
|
Number of the network via which to advertise the default route.
|
Default
Disabled; that is, all known routes are advertised out the interface.
Command Mode
Interface configuration
Usage Guidelines
If you specify the ipx advertise-default-route-only command, only the default route, if known, will be 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.
Note
Services are not considered to be reachable via the default route. They are not added to the service table unless an explicit route to the server's network is known. Therefore, do not specify the ipx advertise-default-route-only command if you want services advertised via this interface.
Note
Not all routers recognize and support the default route. Use this command with caution if you are not sure if all routers in your network support the default route.
Example
The following example enables the advertising of the default route only:
ipx advertise-default-route-only 1234
Related Command
ipx default-route
ipx backup-server-query-interval
To change the time between successive queries of each Enhanced IGRP neighbor's backup server table, use the ipx backup-server-query-interval global configuration command. 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.
|
Default
15 seconds
Command Mode
Global configuration
Usage Guidelines
A lower interval may use more CPU resources, but may cause lost server information to be retrieved from other servers' tables sooner.
Example
The following example changes the server query time to 5 seconds:
ipx backup-server-query-interval 5
ipx bandwidth-percent eigrp
To configure the percentage of bandwidth that may be used by Enhanced IGRP on an interface, use the ipx bandwidth-percent eigrp interface configuration command. 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
as-number
|
Autonomous system number.
|
percent
|
Percentage of bandwidth that Enhanced IGRP may use.
|
Default
50 percent
Command Mode
Interface configuration
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.
Example
The following example allows Enhanced IGRP to use up to 75 percent (42 kbps) of a 56 kbps serial link in autonomous system 209.
ipx bandwidth-percent eigrp 209 75

ipx broadcast-fastswitching
To enable the router to fast switch IPX directed broadcast packets, use the ipx broadcast-fastswitching global configuration command. To disable fast switching of IPX directed broadcast packets, use the no form of the command.
ipx broadcast-fastswitching
no ipx broadcast-fastswitching
Syntax Description
This command has no arguments or keywords.
Default
Disabled
The default behavior is to process-switch directed broadcast packets.
Command Mode
Global configuration
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.
Example
The following example enables the router to fast switch IPX directed broadcast packets:
ipx broadcast-fastswitching

ipx helper-address
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 global configuration command. 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 [delay]
Syntax Description
delay
|
Delay, in milliseconds, between packets in a multiple-packet RIP update. With Cisco IOS Release 10.0 and Release 10.2, the default delay is 0 ms. With Cisco IOS Release 10.3 and Release 11.0, the default delay is 5 ms. Novell recommends a delay of 55 ms.
|
Default
With Cisco IOS Release 10.0 and Release 10.2, the default delay is 0 ms (that is, no additional delay between routing update packets). With Cisco IOS Release 10.3 and Release 11.0, the default delay is 5 ms.
Command Mode
Global configuration
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.
Example
The following example sets a default interpacket delay of 55 ms for RIP updates sent on all interfaces:
ipx default-output-rip-delay 55
