Redundant Ports

NiteshS — Tue, 09 Sep 2014 10:18:32 GMT

Hi,

the customer is looking for a redundant ports as there looking for a cross connection between two different switches.

is this possible? etherchannel/aggregate port configuration doesn't solve that issue as aggregate port goes in the same switch only.

Please suggest a way to resolve this.

Thanks & Regards

Nitesh

Hi Nitesh

if your switch supports spanning portgroups/aggregates across different chassis in a stack, you can solve this issue with an aggregate port group

If you are unable to stack your switches, you could try setting multiple ports in L2 mode

hence you are saying we will do the following

1. Create a VLAN

2. Create a VLAN SVI and assign this to zone and vr

3. assign multiple ports in the same vlan

4. connect to the FW port to different switch and let spanning-tree on the switch do the blocking of the port.

Hi Nitesh,

You are almost correct. Follow bellow instructions.

1.) Created new VLAN

2.) Created new VLAN interface (with L3-forwarding enabled)

3.) Placed new VLAN interface into appropriate security zone (L3-Trust in my configuration)

4.) Assigned new VLAN interface an IP Address (192.168.1.1/24 in my config)

5.) Configured 2 firewall ports as "Layer 2" and placed them into the newly created VLAN from step #1

Commit

On the switch side, I created a vlan in a Brocade switch with 3 access ports. I also enabled spanning-tree in this VLAN. Of the 3 ports, 2 go to the firewall and one to a test laptop.

In this configuration, everything works fine! It takes 30-45 seconds to fail over, and about 15s to fail back - which is expected for standard spanning-tree behavior.
