Configure Port Speed for All VIM Ports

Note

This procedure only applies to 5520 Series and 5720 Series.

Configure all of the ports on an installed Versatile Interface Module (VIM) to operate at the same speed.

Note

Some VIMs must operate with all ports at the same speed, or a group of ports at the same speed, while others can operate with ports at different speeds. For more information, see Fabric Engine Release Notes. You can configure VIM ports speed only on VIMs that must operate with all ports at the same speed.

Before you begin

Install the VIM before performing this procedure.

About this task

Note

It is a best pratice not to use a mix of 10Gbps and 25Gbps VIMs with the auto parameter.

Use this procedure to configure the speed of all ports in a multi-port VIM to operate at either 1 Gbps, 10 Gbps, 25 Gbps, or auto.

Procedure

In the navigation pane, expand Configuration > Edit.
Select Chassis.
Select the VIM tab.
Select mbps1000, mbps10000, mbps25000, or auto.
Select Apply.

VIM Field Descriptions

Use the data in the following table to use the VIM tab.


Name	Description
AdminSpeed Note: Exception: 1 Gbps port speed applies to 5720-VIM-6YE only.	mbps1000: Configures all ports or a group of ports in a multi-port VIM to operate at 1 Gbps. mbps10000: Configures all ports in a multi-port VIM to operate at 10 Gbps. mbps25000: Configures all ports in a multi-port VIM to operate at 25 Gbps. auto: Configures all ports in a multi-port VIM to operate at the detected link speed. The command auto vim-speed is enabled by default.
GroupSpeed Exception: only applies to 5720-VIM-6YE.	Configures all ports into two speed setting groups. group1: ports 2/1, 2/2, 2/3 group2: ports 2/4, 2/5, 2/6 Ports in groups must be configured to operate at the same speed. For example, ports 2/1, 2/2, 2/3 can be configured for 10 Gbps, and ports 2/4, 2/5, 2/6 can be configured for 25 Gbps. If 5720-VIM-6YE uses the LRM/MACsec Adapter, you must configure the groups according to the SFP or SFP+ inserted in the Adapter.
