We have a couple of ASA 5510s running OS v7.0(6) setup with A/S failover.
The firewall has 4x 100mbps interfaces. These interfaces have been configured as follows
e0: Outside (internet facing)
e1: Inside (internal facing)
e2: 802.1Q trunk (DMZ subinterfaces with various security levels)
e3: 802.1Q trunk (DMZ subinterfaces with various security levels)
I am attempting to setup 802.1Q trunk on the e1 interface which connects back to a 6509 running CatOS 8.4(6) on the active firewall and IOS 12.2(17) on the standby firewall.
When I complete the setup, connectivity between the FW devices and the 6509's fails. By that I mean L2 and L3 connectivity (ie. SPAN shows no traffic on the uplink to the firewall)
Can anyone offer any insight on the root cause of my problem?
I have inlcuded an extract of the configuration here for your review:
no ip address
no nameif inside
ip address 172.19.1.1 255.255.255.0 standby 172.19.1.2
ip address 192.168.7.1 255.255.255.0 standby 192.168.7.2
Set vlan 8 name ABC
trunk 1/5 on dot1q 1-4094
sw trunk encap dot1q
sw mode trunk
sw trunk allow vlan add 1
sw trunk allow vlan add 8
Thanks in advance
