Have a question about trunking on an ASA5510. Here is my setup.
3Com switch VLAN300 = ports 5-8 and VLAN301 = ports 9-12. I have both VLANs trunked to port 13.
ASA5510 VLAN300 on ethernet0/3.300 and VLAN301 on ethernet0/3.301. Port 13 on the 3Com switch is attached to ethernet0/3 on the ASA. I assume the next step would be to trunk the two VLANs to ethernet0/3?
I tried to run the following commands:
ciscoasa(config)# interface ethernet0/3
ciscoasa(config-if)# switchport mode trunk
but i get an "Error: % Invalid input detected at '^' marker." The ^ is pointing to the switchport command. Any ideas?
Thanks for your help.
