Very simple- I have two 3750's (SwitchA & SwitchB) connected through an uplink. Multiple servers/storage devices connected to each. I need to enable jumbo frames for a few servers on SwitchA to communicate to a few servers on SwitchB. The 3750 cannot do per port jumbo frames only globally. My question is that if I enable the jumbo on both switches how will the other port/devices deal with that since traffic since they won't be configured for jumbo frames? Will there be performance issues or a problem?
Will rate post.
Thanks!

Hello.
There will not be any performance issue. LAN speed ports can easily handle jumbo frames and if anything there will be an improvement as there will be less overhead.
The other devices will continue to send the same size packets as end devices do not know what the port MTU is configured for. The MTU size that is sent is configured on the end devive itself so they will continue as normal sending their packets (normally MTU 1500)

Thanks, Simon. This is what we suspected.
Cheers!
