IRONPORT S170 failover

[hkvt012345]

All,                   

we got one CiscoIronport s170 on two site, we would like to implement that if one of applicance failed, then the internet traffic will route to another appliance. I understanding that if device connect to L4 switch, it can do that.

if so, may i ask any document provide to set this up?

We currently connecting the device with Cisco 3560x switch..

Hi,

You can take a look to this other post

https://supportforums.cisco.com/thread/2086719

But here you have a summary

High availability with the WSA can be achieved by the various deployment methods.

1.  PAC files can contain entries directing clients to multiple WSA's based  upon various network factors or machine characeteristics.

2. WCCP protocol includes load sharing across multiple WSA

3. Manually configuring clients to different WSA

4. Automatic configuration scripts to point users to specific WSA's based upon subnets, etc

5. Load Balancers that redirect clients to a VIP that points to multiple WSA

6. Layer 4 redirection that can distribute load across multiple devices.

Web Cache Communication Protocol (WCCP) deny  access control entry (ACE) support on Cisco Catalyst 3560-E, 3750-E,  3560-X, and 3750-X: In previous releases, the WCCP protocol only  supported permit ACEs in the redirect-list ACL. In this release, support  for deny ACEs in the redirect list was added.
