[blackmetal]

Hello,

I have a 4500x with 5-6x gre tunnel and totally my gre tunnels are using 200-400mbps traffic and i want to set tcp mss for my gre tunnels ,so in 4500x does TCP MSS support in hardware?

because i do not want TCP MSS affect on my switch CPU

THanks,

". . . 4500x does TCP MSS support in hardware?"

Don't know, but possibly not.  If not, unless you have lots of new TCP flows starting up (MSS adjust not done for every TCP packet), doubtful it would have much of an impact on the switch's CPU.
