We have 6506's with 6724 series line cards (with DFC's) that exibit unicast flooding after the mac timer has expired. Has anyone else seen this problem?

Hi Matt

You need a command doing MAC address synchronization between different dfc cards and the pfc. If you like, I can find it in a configuration.

Hi Matt

The statement you need is:

"mac-address-table synchronize"

else are the mac addresses not exchange between the different dfc cards.

The description can be found at at the release notes of C6500 IOS 12.2SX.
