HP Procurve e5400zl - Stacking / failover question

Hi all

 

i have atm one HP e5400zl in my network working as default gateway and main switch.

 

but is it possible to buy another E5400zl switch and make them Stacking or failover? so if the one switch dies, the 2nd takes over?

 

i known my cisco 3750 switch are stack able and it works like a single unit, one IP address. can the HP 5400zl do that ?

 

 

as far as i know - it isnt - but cant that really be true ?

No, you can't stack 5400s.

 

What you can do is set them up as a VRRP pair, per VLAN.

Both Switches:
ip routing
router vrrp
enable
 
Switch A:
vlan 100
ip address 10.1.1.1 255.255.255.0
vrrp vrid 100
owner
virtual-ip-address 10.1.1.1 255.255.255.0
enable
 
Switch B:
vlan 100
ip address 10.1.1.2 255.255.255.0
vrrp vrid 100
backup
virtual-ip-address 10.1.1.1 255.255.255.0
priority 200
enable

So, the VRRP "owner" will send regular messages to the VRRP "backup" to keep it suppressed.

 

The Owner has 10.1.1.1 on VLAN 100 and so any device on VLAN100 that uses 10.1.1.1 as a default gateway or router address will get its traffic routed by that address.

 

The Backup has 10.1.1.2 on VLAN100 and it functions perfectly well as a layer3 device using 10.1.1.2, but it does nothing with packets addressed to 10.1.1.1.

 

If the Backup stops getting messages from the Owner, it will start responding to packets on VLAN100 aimed at 10.1.1.1 and essentially take over routing for the VLAN.

 

 - The VLAN ID and the VRRP VRID do not have to match. I like it to because I think it looks good. Depends on your VLAN design.

 - Your VRRP VRID has to be in the range 1-255, so you can have many more VLANs than VRIDs. You can use a single VRID for all your VLANs, or you can use seperate ones for each VLAN, up to a maximum of 255 VRIDs.
