Hi Everyone I am trying to find out it i can do a direct replacement of a CE550 cache engine with a CE590 Content engine. If i can are there any new commands to put in the routers to allow the 590 to perform basic caching. Thanks in advance for your help Dave Craddock Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=12820&t=12820 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
