I have one 6509 (core L3 router) switch with sup2/msfc2 running 12.1(13)E11 connected to two 6513's running catos 8.1(3).
We recently change the management vlan ip addresses on all three switches. The 6509 and one of the 6513's operates normally, but one of the 6513's seems to lose arp entries for our management stations. Which causes us to lose the ability to telnet to this switch. We can telnet to the core 6509 and then to the 6513. And if we ping our workstations from the suspect 6513 we then can telnet directly to it. But if we disconnect from the 6513 and wait a few minutes, we again lose connectivity.
Doing a trace on sc0 on the suspect switch (6513b) shows that it does not see any arp broadcasts when we
try to ping the device from our workstations. We can see the broadcasts if we span the trunk port on 6513b but we don't see it on sc0. When we connect a workstation to a port on the 6513b switch and configure it for vlan 10 and span that port, we also don't see any arp broadcasts when doing a trace.
