3Com 10014299 manual Configure length of route reserve queue

376CHAPTER 24: CONFIGURING IPX

When the length of a route reserve queue is 1, the system only saves one route for a destination. If this unique route is faulty, it will be deleted by the system and there will be no route to the destination while searching for the substitute routes, resulting in huge loss of packets. When the length of a route reserve queue exceeds 1, if one route is deleted, it will be replaced with another one as soon as possible, so as to prevent huge loss of packets. However, increasing the length of the route reserve queue in turn increases the system memory that will be occupied by IPX module.

Perform the following task in system view.

Table 414 Configure length of route reserve queue

Operation	Command
Configure length of route reserving queue	ipx rip max-reserve-paths
	length
Restore default value of length of route reserving	undo ipx rip
queue	max-reserve-paths

By default, the length of a route reserve queue is 4.

4Configure Relative Parameters of IPX SAP

aConfigure IPX static service information table item

Generally, only the service notified by NetWare server and saved by the router can be used. In special cases, special services can be specified to use, so that the client can always use this special service. Similar to IPX routes, IPX service information priority is adopted, and smaller value means higher priority of service information. If the route related to the static service information is invalid or deleted, the static service information will be prevented from broadcasting, until the router finds a new valid route related to the service information.

Perform the following task in system view.

Table 415 Configure static service information table item

Operation	Command
Add one static service information	ipx service service-type name
	network.node socket hop hopcount [
	preference preference ]
Delete one static service information	undo ipx service { service-type[
	name [ network.node ] ] [ preference
	preference] } all

By default, the priority of static service information is 10, and that of dynamic service information is 60.

bConfigure updating period of IPX SAP

In a huge network, one IPX SAP broadcast occupies much of the bandwidth. For interfaces running protocols such as PPP, X.25 and frame relay, the bandwidth is limited, therefore changing IPX SAP updating period is an effective method to reduce bandwidth occupation. You should make sure that all servers and routers on the network have the same SAP updating period, otherwise, the router might think that a server fails to work, while the server is still working.
