Customizing NetBIOS over IP
117358-A Rev. A 8-7
If the router receives a broadcast name query request from a client and finds the
name and associated IP address of the requested server in its cache, the router
replaces the broadcast address on the name query request with the unicast IP
address. The router also assigns the entry a short time to live. If the entry is valid,
the router will receive a positive name query response (which will validate the
entry) from the server within the specified time to live. If the entry is invalid, the
name query request will not reach the server. In this case, the entry quickly ages
out.
By default, inactive NetBIOS names expire from the NetBIOS name cache after
300 seconds.
You can use Site Manager to specify any time value that can rapidly age
infrequently referenced names out of the NetBIOS name cache.
Choose an aging value that allows infrequently referenced or obsolete server
names to expire from the name cache. The smaller the value, the less efficient
broadcast reduction is, but the more quickly the network recovers topology
changes.
