...on the Serial Ports? The Cisco 3000 has a 50 PIN serial V2 cable and the Cisco 2501 has a standard serial port, like that on the back of a PC.What type of cable should i use? There are perhaps 4 different types, I think in the manuals, RS-232, X.25.... The manuals do show connecting the Routers to hubs, switches, etc, BUT NOT EACH OTHER. ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
