Enabling Jumbo Frame con Catalyst 4500 WS-X4648-RJ45-E

Hello,

I want to enable jumbo frame con a Catalyst 4500, specifically in the WS-X4648-RJ45-E card. (running this  IOS version Version 12.2(53)SG1).

For what I checked, this are the only needed commands:

vlan xxx

mtu 9000

interface port 4

mtu 9000

exit

I want to be sure that these are the only needed comands and that they won t generate any disruption.

Thanks a lot for your help,

Sergio

Hi,

That is the only command you need.  Verify with show command:

see below:

This example shows how to configure the MTU size on Gigabit Ethernet port 1/1:

switch# conf terminal

switch(config)# interface gi1/1

switch(config-if)# mtu 9198

switch(config-if)# end

switch(config)# end

switch# show interface gigabitethernet 1/2

GigabitEthernet1/2 is administratively down, line protocol is down

  Hardware is C6k 1000Mb 802.3, address is 0030.9629.9f88 (bia 0030.9629.9f88)

  MTU 9216 bytes, BW 1000000 Kbit, DLY 10 usec,

HTH
