ASA5550 VLAN Trunking

Unanswered Question

Hi,


Ive been having issues when creating subinterfaces with vlan id's on the 5550.

The port connecting to the ASA5550 is a trunked port and has the same vlan id as the sub-int on the 5550 and is allowed to trunk the vlan. When this is configured you are unable to ping between the ASA and the switch, icmp is allowed and the security level is configured to 100.


I have the excact same config on ASA 5540'S & 5520'S in the organisation and that is working with out any issues, I don't have different contexts configured. The switch has the mac-address of the ASA but won't pass traffic at layer3.


From what I can see the ASA5550 is configured in the same way as the other models, but the vlan doesn't apper to be trunked across. If the sub-int is deleted and the config moved on to the physical interface the traffic is passed at layer 3 without any issues


Is there anything im missing????
