CSS failover

I have 2 CSS 11150 , I want to configure for fault-tolerant (Active and Standby). If one is down, another will take over.But I don’t know the way that I did it right or not. It is the first time i have worked with CSS. Any advice would much appreciate. Thanks

CSS1(Active)

Circuit VLAN1 (Connect to Server farm)

Ip address 192.168.4.253/24

Ip virtual-router 1 priority 110 preempt

Ip redundant-interface 1 192.168.2.4.252

Ip critical-service 1 Critical

Circuit VLAN2 (Public Network)

Ip address x.y.z.186 /24

Service Critical

Ip address 192.168.4.254 # Ip address of Css2

type redundancy-up

active

CSS2(Standby)

Circuit VLAN1 (Connect to Server farm)

Ip address 192.168.4.254/24

Ip virtual-router 1 priority 100 preempt

Ip redundant-interface 1 192.168.4.252

Ip critical-service 1 Critical

Circuit VLAN2 (Public Network)

Ip address x.y.z.187 /24

Service Critical

Ip address 192.168.4.253 # Ip address of Css1

type redundancy-up

active

Default Gateway of server farm points to 192.168.4.252. Vlan on each CSS is connected to L2 switch. I also have 2 3640 routers connected to same switch with CSS Vlan2 running HSRP.

Re: CSS failover

It looks like you may have configured critical services and VIP and Interface redundancy. Box-Box redundancy is a bit easier to configure if you are looking for simple Active-Stndby failover (also known as box-box) redundancy. Here is a link that may help you out with configuring this:

or more specifically:

Remember to rate these docs if they helped you or not as docs are kept on or taken off of CCO by the feedback we receive from our customers. I hope this helps!!
