Restoring Backups

To restore a backup configuration on the Oracle® Enterprise Session Border Controller:

In Superuser mode, enter the restore-backup-config command followed by the backup filename you want to restore to the current configuration. You must explicitly name the backup file you want to restore, including the file extension
```
ORACLE# restore-backup-config 02_Feb_2008.tar.gz
Need to perform save-config and activate/reboot activate for changes to take effect...
task done
ORACLE#
```

Correct the Virtual MAC address configuration established on the former device to be suitable for the new device.

Establish the base MAC needed for HA operation by, first, determining the base MAC by way of the ethernet address value of the show media physical command.

ORACLE#show media physical
s0p0 (media slot 0, port 0)
     Flags: UP BROADCAST MULTICAST ARP RUNNING
     Type: ETHERNET_CSMACD
     Admin State: enabled
     Auto Negotiation: enabled
…
     Ethernet address is 00:08:25:01:08:44

Apply the formula for calculating virtual MAC addressing to the MAC addressing used for this system. This formula is described in the ACLI Configuration Guide.

Configure the physical interfaces with the computed virtual MAC addressing. Refer to the following command line sequence as an example of this procedure.

ORACLE# configure terminal
ORACLE(configure)# system
ORACLE(system)# phy-interface
ORACLE(phy-interface)# select
<name>:
1: s0p0
2: s1p0
selection: 1
ORACLE(phy-interface)# virtual-mac 00:08:25:01:08:48
ORACLE(phy-interface)# done
phy-interface
        name                           s0p0
        operation-type                 Media
        port                           0
        slot                           0
        virtual-mac                    00:08:25:01:08:48

Save the configuration.
```
ORACLE# save-config
```
Activate the configuration.
```
ORACLE# activate-config
```
