Enable the Proxy Explorers Feature on the Appropriate Interface

In order to enable NetBIOS name caching on an interface, the proxy explorers feature must first be enabled on that interface. This feature must either be enabled for response to all explorer packets or for response to NetBIOS packets only.

To determine whether the proxy explorers feature has been enabled, use the following command in EXEC mode:

Command	Purpose
show startup-config	Determine whether or not the proxy
	explorers feature has been enabled.

To determine whether proxy explorers has been configured for response to all explorer packets, look in the configuration file for the source-bridgeproxy-explorerentry for the appropriate interface. For example, if the appropriate interface is Token Ring 0, look for an entry similar to the following:

interface tokenring 0 source-bridge proxy-explorer

If that entry does not exist, look for the source-bridgeproxy-netbios-onlyentry for the appropriate interface.

If neither entry exists, proxy explorers has not yet been enabled for the appropriate interface. To enable proxy explorers for response to all explorer packets, refer to the section “Configure Proxy Explorers” later in this chapter.

Otherwise, enable proxy explorers only for the NetBIOS name caching function by using the following command in global configuration mode:

Command	Purpose
source-bridge proxy-netbios-only	Enable use of proxy explorers only
	for the NetBIOS name caching
	function and not for their general
	local response to explorers.

Specify Timeout and Enable NetBIOS Name Caching

After you have ensured that the proxy explorers feature has been enabled for the appropriate interface, you can specify a cache timeout and enable NetBIOS name caching. To do this, use the following commands:

Step	Command	Purpose
1	netbios name-cache timeout minutes	Specify the timeout for entries in the
		NetBIOS name cache.

2	netbios enable-name-cache	Enable NetBIOS name caching for
		the appropriate interfaces.
