2610/2950 Duplex Mismatch

[RLEE5]

Greetings All:

I've recently installed a bunch of 2610 routers & 2950 switches at our branch offices. I set the ether0/0 (on the router) and the coresponding port on the swt(fast0/24) to 10MB / full-duplex (hard). They all set up & work well except for 1 set. 1 of the 2950's keeps giving me:

14:43:45: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on FastEthernet0/24 (not half duplex), with ****** Ethernet 0/0 (half duplex).

I've tried every trick I know of & it still gives me the above error. The strange thing is I'm NOT getting alot of collisions,etc on either interface.

Is the switch just confused?

If you have not already done so, move a known good and working router to the switch and test again. If that resolves the problem try reconfiguring or replacing the router. If the test yields the same result, try connecting the original router to a known good switch. If that resolves the problem try reconfiguring or replacing the switch. If that yields the same result, try replacing cables etc.

interface fastethernet0/2

duplex full

speed 100

Just spitballing...
