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.
