MTU Issues on Fast Ethernet Interfaces

[johnso100]

Hi All,

I'm currently experience MTU issues between 7609 and various 7X00 platforms via the fast ethernet interfaces. We MPLS enabled, so there are labels being appended, but there doesn't appear to be any fragmentation on these interfaces. Has anyone experienced these issues on these interfaces before?

Regards

Mark

Not sure of the issue, but you check for the configuration from this link on Jumbo/Giant Frame Support on Catalyst Switches Configuration Example :
