tag-swithing mtu 1600 results in giants

Hi, last friday we upgraded our first E3 mpls connection to 1Gigabit (Cat6513 IOS 12.2.18SXD4 with WS-X6516-GBIC and WS-G5487). The connection seems to work well but I see a lot of input errors (which are all giants) on the interface. I configured tag-swithing mtu 1600. Does anyone know if I should change the interface mtu size as well ?

Best regards, Peter

You seeem to be running into CSCef94635, which is fixed in 12.2(18)SXE.

The workaround is to configure the "mtu" statement on the interface.

Hope this helps,

Try mtu 1524 for tag-switching instead of 1600.
