show port jumbo

Use this command to display the status of jumbo frame support and Maximum Transmission Units (MTU) on one or more ports.

Syntax

show port jumbo [port-string]

Parameters

port-string (Optional) Displays the status of jumbo frame support for specific port(s).

Defaults

If port-string is not specified, jumbo frame support status for all ports will display.

Mode

All command modes.

Usage

On the S- and K-Series it is possible for Jumbo Admin Status to be enabled and Jumbo Oper Status to be deferred. Jumbo frame support is supported on all module ports, but some modules can only handle 12 jumbo enabled ports at one time without a reset. Resetting the module will enable deferred ports.

Example

This example shows how to display the status of jumbo frame support for port ge.1.1:

System(rw)->show port jumbo tg.1.1
