[c-nsp] 3750 running jumbo frames ?

[Jeff Fitzwater]

	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


Jeff
