Hopefully somone can help me with this annoying issue.
In our organisation we have a ASA5510 thats connected to a HP switch with several different vlans and they all work fine.
Now I would like to add a new vlan to trunk over to the switch, whats happening is this:
* I add the subif, set the vlan id and ip address.
* Then the ASA5510´s mac address is visible on the paticular vlan in the switch for like 5 mins and then it disappears!
Int wont retun until I re inter the ip address on the interface, but then again after 5 mins its gone from the switch.
Note that this vlan is not i service yet i am still setting this up.
Erlier I did this on a 5520 we have without any problems at all.
Anyone have any ideas how to solve this?
