Well, better you check current MTU settings using command # sh interfaces | inc MTU
And cheers :) Yes of course you need to adjust routers MTU as well; if you are running with MPLS or gre Regards, Masood Ahmad Shah -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, January 03, 2008 9:19 AM To: [email protected] Subject: Re: [c-nsp] MTU Issue on QinQ Eth link with MPLS Quoting Matt Carter <[EMAIL PROTECTED]>: > Catalyst 2950/2955 Series > http://www.cisco.com/en/US/products/hw/switches/ps700/products_configuration > _example09186a008010edab.shtml#c5 > > You can classify the Catalyst 2950/2955 Series switches into two major > groups, where one supports baby giants (up to 1530 bytes), but the other > does not.
