Configuring System Classes
S e n d f e e d b a c k t o n x 5 0 0 0 - d o c f e e d b a c k @ c i s c o . c o m
In the following example, the default Ethernet system class is configured to support the jumbo MTU:
switch(config)# policy-map jumbo
switch(config-pmap)# class class-default
switch(config-pmap-c)# mtu 9216
switch(config)# system qos
switch(config-system)# service-policy jumbo
The system jumbomtu command defines the maximum MTU size for the switch. However, jumbo MTU
Note
is only supported for system classes that have mtu configured.

Verifying Jumbo MTU

To verify that jumbo MTU is enabled, enter the show interface ethernet slot/port command for an
Ethernet interface that carries traffic with jumbo MTU.
The following example shows how to display summary jumbo MTU information for Ethernet 2/1 (the
relevant part of the output is shown in bold font):
switch# show interface ethernet 2/1
Ethernet2/1 is up
...

The following example shows how to display detailed jumbo MTU information for Ethernet 2/1 (the
relevant part of the output is shown in bold font):
switch# show interface ethernet 2/1 counters detailed
