[c-nsp] Intermittent management vlan conectivity

[Kelvin Goei]

Hi I have one 6513 edge switch with SUP32, its connected to 2 Up stream Distribution Switch using portchannel. There is another 3550 edge switch connected to the 6513 edge switch with single uplink. All have management Vlan on Vlan2. The problem now is the ping to interface Vlan2 for the edge switch6513 and other 3550 switch connected to it is intermittent. I checked on the interface Vlan2 for both the 6513 and 3550 both have proxy-arp enable, but not on the Distribution Switch. What could be the reason for this? The switch is up all the time, and user traffic on other vlan is ok, just traffic from Vlan2 is intermittent. Any help really appreciated.

Thanks.

Regards,

Kelvin.
