Step 2: Clear the NVRAM Contents

Purpose

Currently the storage area for the logs on the NVRAM is limited to 4 KB. You need to delete old NVRAM logs to make room for new ones.

Action

To clear the content of the NVRAM after you have captured the necessary information, follow these steps:

1. Exit from the CLI environment and create a UNIX-level shell by entering the start shell command:

user@host> start shell 

2. Type su and the root password when prompted. You are now in the shell and the prompt is % instead of >, for example:

% su

Password: ****

3. Establish a vty session to the appropriate component. Use the vty command followed by the abbreviation for the component, for example:

root@host% vty sfm0

The vty prompt will vary depending on the component, for example:

SFM3(host vty)# 

FPC1(host vty)# 

4. Type the clear nvram command, for example:

SFM3(host vty)# clear nvram

FPC1(host vty)# clear nvram
