One of my customers sent the following information to me.
Is this a documented bug?
What is the bug ID?
IOS bug on 3750 switches 12.2(37)SE
Switch drops arp packets to certain mac addresses with version 12.2(37)SE.
Wwitches sharing cat3750 architecture may drop arp packets destined to mac addresses that are close to switch own mac address block
- downgrade to 12.2(35)SE
- If affected device supports it, change the mac address for which arps are dropped (very likely the mac address affected will also be of Cisco device)
Issue is being investigated
