Jumbo frames routing on Catalyst 4507 R+E?

[skagregogo]

Hello everyone,

Does somebody knows if the catalyst 4507R+E with WS-X45-SUP7-E supervisor is able to route jumbo frames? In global config mode I only see the "System mtu" command but not "System mtu routing" such as in the 3750X.

Thanks in advance,

Greg.

FYI: The IOS version is cat4500e-universalk9.SPA.03.03.00.SG.151-1.SG.bin with IPBASE license.

Hi Gregory,

See this:

The Catalyst 4500 series switch allows you to configure a maximum of 32 different maximum transmission unit (MTU) sizes system wide. This means that the maximum number of different MTU sizes that you can configure with the system mtu, mtu, ip mtu, and ipv6 mtu command on all Layer 2 and Layer 3 interfaces combined is 32.

The only commands supported are system mtu, mtu, ip mtu, and ipv6 mtu command so I guess that the one that will be similar is ip mtu.

Here is the link for the IOS you have:

Hope it helps..
