I forgot to mention that the hosts that will be using jumbo frames,
will be on a separate VLAN between the two switches. The concern was
since the jumbo frame was a global change (all gig ports on 3750), how
would it impact the other vlan that only has 1500 MTU hosts on. I
would assume there isn't any impact for hosts with a 1500 MTU, its
just that the switch can now pass 9k frames if present. The switch
management was the other key issue.
Thanks

(That is, if this will work)
If I enable jumbo frames (which is a global change) and leave the
management interface MTU at 1500 so the switch will use 1500 as
packet size for all management, is there any NEGATIVE ISSUES I
should be aware because of them being connected to the non-jumbo
environment?
Thanks for any help,
