I tend to run into this table often and has been a good reference for me. This table relates specifically to system MTU: http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note 09186a00801350c8.shtml#topic2
This would suggest 'system mtu 1504' would be appropriate. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dan Armstrong Sent: Wednesday, March 26, 2008 16:02 To: [email protected] Subject: [c-nsp] System MTU on trunks for Q in Q I've been bashing my head against the wall all day for a definitive answer on this: On a Cisco switch that supports QinQ (3550, 3750, ME3400, 3560 etc) What is the _minimum_ value I need to set the system MTU to, to do QinQ? 1504? 1522? 1526? 1546? I can't seem to find one concise answer...
