Take a look at: http://wiki.centos.org/TipsAndTricks/BondingInterfaces?highlight=% 28Bonding%29 1. Can you try at least try the other Bonding Modes please? 2. Try another Switch? 3. What info I can glean is the 2dot3ad will work on the IOS version you have. 4. Did you validate that Both NIC Cards in the Server works and there not like flaking out? 5. Another thought is are they the same brand? Linux it should not matter but you never know. 6. Validate the NICS working separatly? Instead of in Bonding mode? 7. Faulty cableling, connectors and such. 8. Do you have the bunding configured right on the server? Some of questions may sound rhetorical and stupid but I have found many times it was the simplist thing that was wrong. The link on the wiki bonding will work. It is a good example, clear and concise. > > > --Tim > _________________________________________________________________________ > / You know it's going to be a bad day when you want to put on the clothes \ > \ you wore home from the party and there aren't any. / > ------------------------------------------------------------------------- > \ > \ \ > \ /\ > ( ) > .( o ). > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos -- ~/john OpenPGP Sig:BA91F079
