With this feature, a call setup and call disconnect "start-stop" accounting record tracks the progress of the
resource connection to the device. A separate user authentication "start-stop" accounting record tracks the user
management progress. These two sets of accounting records are interlinked by using a unique session ID for
the call.
The figure below illustrates a call setup sequence with AAA resource start-stop accounting enabled.

VRRS Accounting
Virtual Router Redundancy Service (VRRS) provides a multiclient information abstraction and management
service between a First Hop Redundancy Protocol (FHRP) and a registered client. The VRRS multiclient
service provides a consistent interface with FHRP protocols by abstracting over several FHRPs and providing
an idealized view of their state. VRRS manages data updates, allowing interested clients to register in one
place and receive updates for named FHRP groups or all registered FHRP groups.
Virtual Router Redundancy Protocol (VRRP) is an FHRP that acts as a server that pushes FHRP status
information out to all registered VRRS clients. Clients obtain status on essential information provided by the
FHRP, including current and previous redundancy states, active and inactive L3 and L2 addresses, and, in
some cases, information about other redundant gateways in the network. Clients can use this information to
provide stateless and stateful redundancy information to clients and protocols.
VRRS Accounting Plug-in
The VRRS Accounting plug-in provides a configurable AAA method list mechanism that provides updates
to a RADIUS server when a VRRS group transitions its state. The VRRS accounting plug-in is an extension
of existing AAA system accounting messages. The VRRS Accounting plug-in provides accounting-on and
accounting-off messages and an additional Vendor-Specific Attribute (VSA) that sends the configured VRRS
name in RADIUS accounting messages. The VRRS name is configured using the vrrp name command in
interface configuration mode.

The VRRS accounting plug-in is an extension of existing AAA system accounting messages. The VRRS
Accounting plug-in provides accounting-on and accounting-off messages and an additional Vendor-Specific
Attribute (VSA) that sends the configured VRRS name in RADIUS accounting messages. The VRRS name
is configured using the vrrp name command in interface configuration mode. The VRRS Accounting plug-in
sends an accounting-on message to RADIUS when a VRRS group transitions to the master state, and it sends
an accounting-off message when a VRRS group transitions from the master state.
The following RADIUS attributes are included in VRRS accounting messages by default:
• Attribute 4, NAS-IP-Address
• Attribute 26, Cisco VSA Type 1, VRRS Name
