I have a major problem. I have a catalyst 2950 to a catalyst 4006 via fiber. I can ping a normal size packet from one to the other, but when I use a datagram of 1500 it fails.. Would appreciate any ideas... repaced 2950 with two other switches and a new fiber patch cable to fiber box... 4006 moved to two other gbic locations..
Figured it out.. Turns out the two gbic's where not the same manufacture which caused large issues... Changed over to Cisco GBICS and problem is now gone and can send a 1500 datagram size in ping.. Thanks for all the suggestions.
I know when you ping from a 4006 it will not let you use anything larger than 1472 , try that . Try 1472 or below. You are just pinging the mgt address so try to ping something else within that address range with 1500 . May be something with the 4006 supervisor or a restriction with catos.
