First time configuring the FWSM. I come from the days where firewalls were actually appliances. I know, so 2007!
I am having trouble following the nice 700 page guide on the FWSM. I am going through the chapter on Configuring Failover.
I ran into an error when configuring the faolover lan interface.
Here is what I want to do and hopefully you can walk me through this.
I have a server that will be plugged into VLAN 100 on port 6/1 on my CoreA 6513 and CoreB 6513. He will be bonded active/passive. I want him to use a default gateway of 10.10.10.1.
I need the FWSM to present the 10.10.10.1 ip address to the server on both the FWSMs. In the olden days (prior to FWSM) I would put an IP of 10.10.10.2 and a standby of 10.10.10.1 on CoreA and an IP of 10.10.10.3 and a standby of 10.10.10.1 on CoreB to make this happen.
On both FWSM I have created interface VLAN 100 with name TrafficCtrlA. On FWSM A I put IP 10.10.10.2/24 standby 10.10.10.1 and on FWSM B I put IP 10.10.10.3/24 standby 10.10.10.1.
I can add the failover lan unit primary command but then when I add the failover lan interface (if_name) vlan (vlan) part, I get an error that says the interface already exists. Of course it does! I just added it!
Not sure what to do with that.
