Oh cool, I only mentioned it because I've witnessed some very odd behavior in
GNS3 on both Windows and Mac OS-X where two interfaces are configured, one for
VLAN X and one for VLAN Y. The issue is that even though the interfaces are in
the correct VLAN's according to the running configs, on VLAN X actually exists
in the VLAN database, and VLAN Y isn't there. Now this is where it gets fun,
when you go into VLAN database mode and try to add the VLAN you're presented
with the following error:
SW1#vlan database
SW1(vlan)#vlan 200
VLAN 200 added:
Name: VLAN0200
SW1(vlan)#exit
% not enough space on flash to store vlan database. trying squeeze...First
create squeeze log by erasing the entire device
At this point the squeeze fails and we have to resort to more drastic measures
% error squeezing flash - (Missing or corrupted log)
Error on database apply 40: NV storage failure
Use 'abort' command to exit
SW1(vlan)#
The only way I've been able to add any new VLAN's when this occurs is to delete
VLAN.DAT, erase flash, and then reload.
SW1#erase flash:
SW1#delete /force /recu vlan.dat
It seemed like you may have been suffering from this same issue, however
clearing the ARP in your case is a much simpler resolution than this one :)

Are they in the same vlan? Does the vlan exist? Go into vlan database mode on
cat1 and verify.
Vlan database
Show current
If its not there add it in and try again.
