HiWe are in a process of starting to work on a design with several IPS 4270. The demand is to make the design redundant and with high availability. As I am aware of there no redundant support (e.g. no protocol support like HSRP) within the IPS itself...
HiIPS 42xx does not support failover. You can however still make a redundant design. Please have a look at this:http://www.cisco.com/en/US/partner/prod/collateral/vpndevc/ps5729/ps5713/ps4077/prod_white_paper0900aecd806e724b.htmlRegardsJohan
