Configuring failover interface set

A Failover Interface Set (FIS) is a logical group of interfaces. In an HA configuration, using a FIS is a way to prevent failover by grouping interfaces so that, when one interface fails, other functioning interfaces are still available. A FIS can also be configured for the nodes of a Citrix ADC cluster.

HA MON interfaces that are not bound to an FIS are known as critical interfaces (CI) because if any of them fails, failover is triggered.

Note:

An FIS does not create an active and standby configuration. It also does not prevent bridging loops when connecting to links to the same VLAN.

Creating or Modifying an FIS

To add an FIS and bind interfaces to it by using the command line interface

At the command prompt, type:

add fis <name>
bind fis \<name\> \<ifnum\> ...
show fis \<name\>

Example

> add fis fis1
 Done
> bind fis fis1 1/3 1/5
 Done
<!--NeedCopy-->

An unbound interface becomes a critical interface (CI) if it is enabled and HA MON is on.

To unbind an interface from an FIS by using the command line interface

At the command prompt, type:

unbind fis \<name\> \<ifnum\> ...
show fis \<name\>

Example

> unbind fis fis1 1/3
 Done
<!--NeedCopy-->

To configure an FIS by using the GUI

Navigate to System > High Availability and, on the Failover Interface Set tab, add a new FIS, or edit an existing FIS.

Removing an FIS

When the FIS is removed, its interfaces are marked as critical interfaces.

To remove an FIS by using the command line interface

At the command prompt, type:

rm fis <name>

Example

> rm fis fis1
  Done
<!--NeedCopy-->

To remove an FIS by using the GUI

Navigate to System > High Availability and, on the Failover Interface Set tab, delete the FIS.
