Term Description
ICR cluster Group of E Series routers participating in interchassis redundancy
(ICR) deployment.
ICR interface Physical interface, for example, gigabitEthernet 3/1/3, on an E Series
router on which ICR is enabled. The ICR interface is always tied to
a unique router.
ICR partition A logical group of subscriber interfaces within a single ICR interface.
For example, the ICR partition can be a group of S-VLANs configured
on a single physical interface. You can create multiple partitions on
each ICR interface and configure the number of partitions, as well
as assign subscribers to the partition. An ICR partition can be
configured as master or backup.
VRRP Virtual Router Redundancy Protocol. Use VRRP to prevent loss of
network connectivity by configuring backup routers. The backup
routers maintain network connectivity when the master router fails.
You can configure unique VRRP instances to manage each ICR
partition.
VSA Vendor-specific attributes. VSAs are defined by remote-access server
vendors to customize how RADIUS works on their servers. VSAs can
be used in combination with RADIUS-defined attributes.
