Enabling Jumbo MTU in Dell & Cisco Switches
I have 2 Cisco WS-CBS3130G-S-F & 5 Dell PCM6220s connected a Cisco 6506 switch. the Uplinks are configured as port channels.
Now i want to set the MTU size of these port channels as 9198. Is it advisable to increase the MTU in the port channel alone or to the entire switch.
If i need to implement it for the Po...then should i increase it for Po alone or to the ports that are binded for the Pos.
Also for a Cisco switch how to increase the MTU for one particular interface.
In Dell I am able to loginto the interface and set it, but in Cisco I am not able to.

Hi Tamas,
Thanks. But it works only the higher end switches like 6500 series not on a chassis switch module (CBS3130G)

On the 3130, use "system mtu jumbo":

Yes "system mtu jumbo" will work on global mode...not on interface mode. (for particular Interface)

This is for layer 2. You can configure L3 MTU with "ip mtu <mtu>".
