CSS11051 redundancy: Will it work on varying CSS license?

[a.manosca]

Hello,

I am trying to setup redundancy between 2 CSS11051 loadbalancers on Active/Standby. Whenever I connect them both to the network they both act as Master.

They have the same code but varying in flash and feature set. Will redundancy work on this varying items?

CSS11050> sh version

Version: ap0500105 (5.00 Build 105)

Flash (Locked): 3.10 Build 33

Flash (Operational): 5.03 Build 15

Type: PRIMARY

Licensed Cmd Set(s): Standard Feature Set

CSS11050WC_A# sh ver

Version: ap0500105 (5.00 Build 105)

Flash (Locked): 5.00 Build 105

Flash (Operational): 5.00 Build 105

Type: PRIMARY

Licensed Cmd Set(s): Standard Feature Set

Enhanced Feature Set

SSH Server

I connected the cross cable PRIOR to powering up the standby CSS to avoid making both CSS master.

Both CSS have the same config EXCEPT:

On the primary CSS:

************************** CIRCUIT **************************

circuit VLAN404

ip address 10.128.138.38 255.255.255.0

ip virtual-router 1 priority 200

ip virtual-router 2 priority 200

ip redundant-vip 1 10.128.138.36

ip redundant-vip 2 10.128.138.37

On the secondary CSS (standby):

!************************** CIRCUIT **************************

circuit VLAN404

ip address 10.128.138.39 255.255.255.0

ip virtual-router 1 priority 150

ip virtual-router 2 priority 150

ip redundant-vip 1 10.128.138.36

ip redundant-vip 2 10.128.138.37

They were working before the secondary CSS got RMA.

Please advise..

The CSS doesn't check the license.

The cross-cable woul be used for box-to-box redundancy and the command you show are for interface/vip redundancy.

These are 2 different redundance modes that should not co-exist.

So, determine which mode you need first.

Box-to-box redundancy works with a cross-cable.

But if you do interface/vip redundancy, the CSS will communicate through the vlan itself.

In this case vlan404.

If the standby is not attached to vlan404 you are in trouble.
