Hi,

I have two spare HP ProCurve 5406zl Switches.

Do they have the capability to be stacked?

Simple Stackable feature is not available but... You can use VRRP, it's working the same way

HP ProCurve 5406zl Switches has VRRP but they require Platinum License

Virtual Router Redundancy Protocol (requires Premium License): VRRP allows groups of two routers to dynamically back each
other up to create highly available routed environments

For Example
If you hae VRRP enabled


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

VRRP is not even  close to stacking. :)

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.

Okay, I think I get you - I've done something simular on the Cisco Nexus Switching before.

If I want to create a 2Gb LACP TRUNK across two of these switches (1Gb on each) will that operate correctly?

No, you need stack for that.

Understood, So if I wanted todo a 2Gb LACP TRUNK I would have to have it on either one core or the other?

Yes.

Nexus use vPC to be able to create etherchannel accross both switches. VRRP is equivalent of HSRP.

Got you - Understood

In terms of connecting both Cores together, would say a 2x 10Gb TRUNK be acceptable?
