Description

Sometimes it may be required to hard-set the speed and duplex of your appliance's network interfaces due to the nature of auto-negotiation and some vendor switches.

Note:  The following changes should be made from a serial session or from a terminal server if possible since changing the interface settings while in an SSH session may cause the SSH session to drop.

Resolution

1.  Log in as “root.” 

(If you are already logged in as “toor” switch user with su to access the root user CLI.)

2. Type:

> help set

 This will show the usage for changing interface settings. This looks like the following:
Usage: set eth<n> [10baseT-FD | 10baseT-HD | 100baseTx-FD | 100baseTx-HD | 1000baseTx-FD | 1000baseTx-HD | auto]
        Change setting for network interface named eth<n>
        where n is a single digit.

 An example change is to set the interface to 100baseTx-FD (for speed 100, full duplex). 

3. Here is a sample command to make that change that on eth0:
> set eth0 100baseTx-FD
> save

The settings must always be saved, otherwise a reboot of the appliance will reset the values back to previous setting of auto-negotiate.
 
Note: You will be prompted to create a new Blue Coat Proxy certificate during the save process.  If you are pulling logs for Blue Coat choose 0 otherwise choose 1 to not create it.
 

Issue/Introduction

This article explains how to manually change the speed and duplex settings of network interfaces for LogLogic LMI when auto-negotiation fails to set them properly.
