I have a 6509 at a remote office that is being replaced by a pair of 3750's (6509 was overkill). I have a port on the 6509 that is configured like this -
description Riverbed:Inpath 0_0 then to Firewall
ip address 10.1.1.1 255.255.255.0
I have never seen a port on a 6509 configured like this. Havent been able to find out why it was set up this way. The rest of the office is on another subnet i.e. 10.1.2.0 255.255.255.0. I can only guess why the port was setup this way. Unfortunately, I am working with a "managed" network, so the carrier handles the router at the office and I cant make any changes myself and have to go though a series of requests/explanations/etc with them to get any changes mande. It will be easiest to make the 3750 work in a similar manner.
I have tried to configure the 3750 to do the replacement port Gi1/0/1 exactly the same way and have been able to get it to take the ip address command. Only thing I can figure out is to create another vlan on the switch, put the ip address for gi1/1 in that vlan interface and then put the port that will replace Gi1/1 on the 3750 into that new vlan.
I am not running any routing protocols on the 6509 and only see a static route pointing to a different address on the 10.1.1.0 subnet from the 6509 which I believe is the onsite firewall. If there is another way around this, I would appreciate any suggestions. A junior engineer will be going out instead of me, so I would like to have this as plug and play as possible.
Many thanks for that. Wouldnt have thought about that. Also appreciate the clarification on the differences between the two platforms. I have my CCNP Security but this reinforces why I need to get my CCNP R/S.
