Incorrect mapping of
NetBIOS name cache
server-to- client
mapping
The following is an example of the show netbios-cache exec command:
cantatrice#show netbios-cache
HW Addr Name How Idle NetBIOS Packet
Savings
1000.5a89.449a IC6W06_B TR1 6 0
1000.5a8b.14e5 IC_9Q07A TR1 2 0
1000.5a25.1b12 IC9Q19_A TR1 7 0
1000.5a25.1b12 IC9Q19_A TR1 10 0
1000.5a8c.7bb1 BKELSA1 TR1 4 0
1000.5a8b.6c7c ICELSB1 TR1 - 0
1000.5a31.df39 ICASC_01 TR1 - 0
1000.5ada.47af BKELSA2 TR1 10 0
1000.5a8f.018a ICELSC1 TR1 1 0
The following are the fields reported by the show netbios-cache command:
• show netbios—Cache field descriptions
• HW Addr—MAC address mapped to the NetBIOS name in this entry.
• Name—NetBIOS name mapped to the MAC address in this entry.
• How—Interface through which this information was learned.
• Idle—Period of time (in seconds) since this entry was last accessed. A hyphen in
this column indicates that it is a static entry in the NetBIOS name cache.
• NetBIOS Packet Savings—Number of packets to which local replies were
made (thus preventing transmission of these packets over the network).
Step 4 Use the show running-config privileged exec command at each router to examine
the mapping of addresses specified in netbios name-cache global configuration
command entries.
The following example shows a configuration in which the NetBIOS server is
accessed remotely:
source-bridge ring-group 2
rif 0110.2222.3333 0630.021.0030 ring group 2
netbios name-cache 0110.2222.3333 DEF ring-group 2
