Question : WS-X4448-GB-SFP setting  MTU size per interface

Hi,

Can anybody tell me if you can set the MTU size for an individual interface on the WS-X4448-GB-SFP? I dont have the card here and cant test it myself. Any help is appreciated.

Thanks

Answer : WS-X4448-GB-SFP setting  MTU size per interface

I have a few of these cards in 4507's.  On my switch, individual ports cannot be configured for individual MTU, it is a system-wide command.  Here's what happens if I try to specify a MTU size on an indvidual port.  Maybe there's a different controller board and/or firmware that can do it.  You might want to call your Cisco reseller/presales support and see if they can confirm if your controller board/firmware combo can do it or not.

SWITCH_01#sh system mtu
Global Ethernet MTU is 1500 bytes.

SWITCH_01#config t
Enter configuration commands, one per line.  End with CNTL/Z.
SWITCH_01(config)#int gi3/1
SWITCH_01(config-if)#mtu ?
  <1500-9198>  MTU size in bytes

SWITCH_01(config-if)#mtu 1500
% Interface GigabitEthernet3/1 does not support user settable mtu.
SWITCH_01(config-if)#mtu 9000
% Interface GigabitEthernet3/1 does not support user settable mtu.
SWITCH_01(config-if)#end
