How can i enable Jumbo frame with EHWIC-4ESG?

Dear all

According to the documentation, it should be supported, 

http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/qa_c67-612908.html

However, i cannot found out any documentation, or any cases on the internet, that can enable this .

I have got a cisco 1921 router but failed with common way to enable the mtu

1921#sh int gigabitEthernet 0/1/0
GigabitEthernet0/1/0 is up, line protocol is up
Hardware is EHWIC-4 Gigabit Ethernet, address is b0fa.ebd3.9ce8 (bia b0fa.ebd3.9ce8)
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 1000Mb/s
ARP type: ARPA, ARP Timeout 04:00:00

1921(config)#int gigabitEthernet 0/1/0

1921(config-if)#system mtu?
% Unrecognized command

1921(config-if)#mtu?

% Unrecognized command

Would you please kindly help on this?

Thanks.

Daniel

System MTU is on global configuration mode, not on interface, so try it there...

On Interface, try IP MTU ...

Thanks.

Hi Daniel!

 

It's changed in vlan configuration mode

 

Enter configuration commands, one per line. End with CNTL/Z.
RIGHT_2911(config)#vlan 511
RIGHT_2911(config-vlan)#mtu ?
<1500-18190> Value of VLAN Maximum Tranmission Unit

RIGHT_2911(config-vlan)#mtu

With best regards
