MTU on GSR

Unanswered Question
Jun 18th, 2008

Hi,

I have a GSR configured for default MTU (1500) on the Gigabit SPA (5 port SPA). The interface is used to configure EoMPLS tunnel with 7600s. So when a large EoMPLS packet (with IP Payload > 1492) which has PPPoE header reaches this interface, does the GSR drop it or pass through?. As it is a L2 packet it cannot be fragmented. If it drops it can affect the traffic, right? Where can I see the drops in the GSR...I do not see the same in the show interfaces..

Thanks,

Prakash

Hi,

You can see in the L2 tunnel information.

ie; show mpls l2transport vc detail.

You will see an output at last like below..

VC statistics:

packet totals: receive <>, send <>

byte totals: receive <>, send <>

packet drops: receive <>, send <>

rate me if this helps you..
