Chapter 29 Configuring IP Unicast Routing
Configuring ISO CLNS Routing
Monitoring and Maintaining IS-IS
You can remove all contents of a CLNS cache or remove information for a particular neighbor or route.
You can display specific CLNS or IS-IS statistics, such as the contents of routing tables, caches, and
databases. You can also display information about specific interfaces, filters, or neighbors.
Table 29-13
lists the privileged EXEC commands for clearing and displaying ISO CLNS and IS-IS
routing. For explanations of the display fields, see the Cisco IOS Apollo Domain, Banyan VINES,
DECnet, ISO CLNS and XNS Command Reference, Release 12.2, use the Cisco IOS command reference
master index, or search online.
