LAN has Switch A (2900XL) connected to Router. Switch B (2950) is connected to Switch A. Both switches only have VLAN1 and each has its own IP address. Network info: 192.168.2.0/255.255.255.0.
Switch A has server 192.168.2.8 and workstation 192.168.2.226 connected.
Switch B has workstations 192.168.2.13, 192.168.2.229, and printer 192.168.2.232 connected.
Cluster management is not enabled; trunk is not enabled between switches.
Symptoms:
192.168.2.13 can not ping or tracert 192.168.2.232 or 192.168.2.229. Can ping and tracert 192.168.2.8 and 192.168.2.226.
192.168.2.229 can not ping or tracert 192.168.2.232 or 192.168.2.13. Can ping and tracert 192.168.2.8 and 192.168.2.226.
192.168.2.8 can ping and tracert everyone.
Switch B can ping everyone but can not trace ip to 192.168.2.232.
Switch A can ping everyone but can not trace ip to 192.168.2.232.
MAC Address table on Switch B is empty.
MAC Address table on Switch A is populated.
This problem didn't used to exist but don't know what changes caused it. Any ideas?

This looks pretty default. You could try to reload the switch and I would add the following for each access-port:
switchport mode access
spanning-tree portfast
Please let me know if this helps, I will have another look at it tomorrow.

It looks as if the problem is with switch B.
All misbehaving nodes are on it and it's mac-table definitely should contain some adresses. It may have turned on the private vlan feature or something like that. Could you post the config of switch B?

I rebooted the switch and the mac-address-table was instantly populated and the other problems went away. Thanks.
