Configure Port Speeds 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 with 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. The sys vim-speed command is supported only on VIMs that must operate with all ports at the same speed. An error message displays if you run the command on an unsupported VIM.

Before you begin

Install the VIM before performing this procedure.

About this task

Note

As a best practice, do not mix 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

Enter Global Configuration mode:

enable

configure terminal
Configure the speed for all of the VIM ports:

sys vim-speed {1000 | 10000 | 25000 | auto}
Configure all VIM ports into two speed setting groups:

sys vim-speed group <1-2> {1000 | 10000 | 25000}

Variable Definitions

The following table defines parameters for the sys vim-speed command.


Variable	Value
1000 \| 10000 \| 25000 \| auto Note: Exception: 1 Gbps port speed applies to 5720-VIM-6YE only.	Configures all ports in a multi-port VIM to operate at either 1 Gbps, 10 Gbps, 25 Gbps, or auto. The command auto vim-speed is enabled by default.
group`<1-2>` Note: Exception: only applies to 5720-VIM-6YE.	Configures all ports into two speed setting groups. group 1: ports 2/1, 2/2, 2/3 group 2: 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.
