cdp enable/disable?
Hi,
I have a Cisco 2610 (I think) router connected to a switch connected to my network. We recently received a couple of VOIP phones (Cisco IP-Phone 7940 series). When I plug these into the network, my syslog receives the following error from the router once a minute:
05-15-2007 16:39:39 Local7.Warning hope.jellico.com 387: 10w3d: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/0 (not full duplex), with SEP001AE22A943D Port 1 (full duplex).I googled it and found some suggestions to just turn cdp off on the Ethernet0/0 interface of the router.
This would get rid of the messages I'm receiving, but do I really want to do that? Are the messages I'm seeing real error messages indicating a problem I should resolve, or are they just informational, letting me know of something that is harmless?
Thanks,
Lisa Casey
