RSRB: Host Cannot Connect to Server (Peers Open)
Possible Problem
Solution
End system
misconfiguration
1.
If the end system is on the ring local to the router, use the
show lnm station
privileged exec command on the local
router. This command lists the stations on the local ring.
The following is an example of the
show lnm station
command:
show lnm station [
address
]
Syntax description:
•
address
—(Optional) Address of a specific LNM
1
station
Sample Display:
The following is sample output from the
show lnm station
command when a particular address (in this case, 1000.5abc15)
has been specified:
Router# show lnm station 1000.5a6f.bc15

2.
Check the command output for the MAC address of the
workstation or server. If the MAC address is not present in
the output, check the configuration of the end system.
3.
If the problem persists, use a network analyzer to check
network traffic generated by the end system. If you do not
have a network analyzer, use the
debug token-ring
and the
debug source-bridge
commands.
Caution:
Using the
debug token-ring
and the
debug
source-bridge
commands on a heavily loaded router is not
advised. These commands can cause further network degradation
or complete network failure if not used judiciously.
Check the output of the
debug
commands to see whether the
end system is sending traffic to the correct MAC addresses
or destination names (in the case of NetBIOS).
