Re: loopback test
A Cisco router actually does a loopback by default every 10 seconds on Ethernet and Fast Ethernet interfaces. Cisco calls it a keepalive, but it's the same as the old-fashioned loopback frame. There's no command to start a loopback test, though. It's an interface configuration command.

RE: loopback test
Hi, If you want to check your protocol stack you should be able to ping yourself, check you ip interfaces and/or check your route table (assuming IP is used). There are a number of utilities that check network cards. Teunis Hobart, Tasmania Australia On Monday, March 19, 2001 at 07:56:26 AM, David A. Lauer wrote: > > Why would you need to?

RE: loopback test
Why would you need to? Do you have a link light at the interface port and the hub/switch? Does the interface show Interface UP line Protocol up? Cat 5 ethernet uses the 568B pinout for the RJ45 connectors. You could create loopback plug by cross-connecting pins 1-3 and 2-6. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of zd z Sent: Monday, March 19, 2001 4:26 AM To: [EMAIL PROTECTED] Subject: loopback test Is there any one knows how to do the loopback test on ethernet or fastethernet port ? __ Do You Yahoo!?
