Change the VRRP Priorities for a Redundant Master Pair
If your deployment uses VRRP to define the primary master in a pair of redundant master switches, and you
are replacing only the primary master switch, and you must change the VRRP priority levels of the switches so
the primary master switch has a lower priority than the backup master switch. This will allow the configuration
from the backup master to be copied to the new master switch, and prevent an old or inaccurate configuration
from being pushed to the local switches.
For details on changing VRRP priorities, see Configuring VRRP Redundancy on page 643.
Back Up the Flash File System
To start the migration process, access the backup or master switch being replaced and create a backup of the
flash file system. You can create a backup file using the WebUI or command-line interfaces.
In the WebUI
To back up the flash from the WebUI, log in to the current backup or master switch and create a flash backup
using the procedure below.
1. Navigate to Maintenance > File >Backup Flash.
2. Select Create Backup.
3. Select Copy Backup to create a copy of the backup file. By default, the flash backup file is named
flashbackup.tar.gz.
4. Next, move the backup the flash file system to an external server. Navigate to Maintenance>Copy Files.
5. In the Source Selection section, select Flash File System.
6. In the Destination Selection section, select one of the server options to move the flash backup off the
switch, and enter the name of the flash backup file to be exported.
In the CLI
To create a flash backup from the command-line interface, access the active master switch and issue the
backup flash command, as shown in the example below.
(host) #backup flash
Please wait while we tar relevant files from flash...
Please wait while we compress the tar file...
File flashbackup.tar.gz created successfully on flash.
Please copy it out of the switch and delete it when done.
(active_host) #dir
-rw-r--r-- 1 root root 17338 Dec 6 08:34 default.cfg
drwxr-xr-x 4 root root 1024 Dec 6 08:34 fieldCerts
-rw-r--r-- 1 root root 21760 Dec 6 09:29 flashbackup.tar.gz
drwx------ 2 root root 1024 Dec 5 08:20 tpm
(host) #copy flash: flashbackup.tar.gz tftp: <your TFTP server IP> flashbackup.tar.gz
Stage the New Switch
The next step in the procedure is to stage the new backup master or active master switch with basic IP
connectivity. Power up the new switch, connect a laptop computer to the switch's serial port, and follow the
prompts to configure basic settings, as shown below:
