ADC-VX Management
Backing Up and Restoring vADCs
ADC-VX supports multiple backup and restore mechanisms for quick and efficient disaster recovery.
vADCs are entities that can be exported and imported in their entirety, similar to virtual machines.
The exported vADCs can be imported to any site or ADC-VX platform available for recovery or for
simple service creation.
The Global Administrator has the following options for backing up and restoring vADC
configurations:
• Backup and recovery of vADC—Backup of a vADC and, upon disaster, recovery of the backed
up vADC to any location with an active ADC-VX platform, with a simple import action (no
configuration necessary).
• Export of vADC—Export a vADC and template creation for quick service creation.
• Global backup and restore—All elements are backed up, including the Global Administration
configuration (vADCs, allocated resource, system settings, and so on) and all vADC
configurations files.
• Selective vADC backup and restore—Individual vADC configurations are backed up.
• Global Administrator infrastructure backup and restore—The Global Administrator
configuration is backed up, but not the vADC configuration files.
For more details, see the section on the
Application Switch Operating System Command Reference.
Integrating vADCs into a Shared Network Design
A shared external interface is a connectivity option that is designed to simplify the integration of
vADCs into existing environments and avoid risky and invasive changes to the existing
infrastructure. Shared interfaces are dedicated tagged or untagged ports that can be assigned to
one or more vADCs as a new interface type.
A shared interface consolidates multiple private vADC communications links with a shared physical
network. Even though each vADC instance is virtualized, they appear and perform in the same
manner as physical ADCs, having dedicated MAC addresses and establishing relationships with
adjacent network ADCs.
To minimize risk when integrating vADCs into a network infrastructure, a shared interface enables
you to integrate into the existing infrastructure without having to make configuration changes or to
allocate new subnets or VLAN IDs. A shared external interface further benefits integration by
enabling you to mirror the connectivity of physical ADCs with the a shared infrastructure.
When you assign a shared external interface to vADCs, the vADCs share a VLAN in the same way
that ADCs in a physical network do. When you set a vADC to be part of a shared network, the vADC
is assigned a virtual MAC address. Both the VLAN (subnet IP) and virtual MAC addresses are visible
to the network and the Internet in the same way that the VLAN and physical MAC addresses are
visible in a traditional ADC design.
You can also have a mixed environment where some of your vADCs are part of the shared network,
while others are not. You may do this, for example, if you want to first test a new vADC
configuration before integrating it into your shared network.
To configure a vADC to be part of a shared network, you set the
to enabled. For an example configuration, see
428.
