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:
To determine whether proxy explorers has been configured for response to all explorer packets, look
in the configuration file for the source-bridge proxy-explorer entry 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-bridge proxy-netbios-only entry 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:
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:
Command Purpose
show startup-config Determine whether or not the proxy
explorers feature has been enabled.
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.
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.
