aaa accounting vrrs

To enable authentication, authorization, and accounting (AAA) accounting of requested services for billing or security purposes when you use the Virtual Router Redundancy Service (VRRS), use the aaa accounting vrrs command in global configuration mode. To disable AAA accounting for VRRS, use the no form of this command.

aaa accounting vrrs default | list-name start-stop method1 [ {method2...} ]

no aaa accounting vrrs default | list-name start-stop method1 [ {method2...} ]

Syntax Description

default	Uses the listed accounting methods that follow this keyword as the default list of methods for accounting services.
list-name	Character string used to name the list of accounting methods. If no list name is specified, the system uses the default value.
start-stop	Sends an accounting-on notice. The accounting-on record is sent in the background. The requested user process begins regardless of whether the accounting-on notice is received by the accounting server.
method1 [method2...]	(Optional) Character string used to name at least one of the accounting methods, tried in the specified sequence.

Command Default

AAA accounting is disabled for VRRS

Command Modes

Global configuration (config)

Command History

Release	Modification
Cisco IOS XE Release 2.6	This command was introduced.
15.1(1)S	This command was integrated into Cisco IOS Release 15.1(1)S.

Usage Guidelines

Use the aaa accounting vrrs command to define a AAA accounting method list. If you define the AAA default accounting method list, you are defining the AAA accounting method list for all the VRRS servers. The default AAA accounting method list is applied to all VRRS groups. To specify a group-specific VRRS method list, use the accounting method command in VRRS configuration mode.

Examples

The following example shows how to configure VRRP group 1 with the group name âvrrp-name-1â to use VRRS method list vrrs-mlist-1:

Router(config)# aaa accounting vrrs vrrp-mlist-1 start-stop group radius
!
Router(config-if)# vrrs vrrp-name-1
Router(config)# accounting mlist vrrs-mlist-1
!
Router(config)# interface gigabitethernet0/2/2
Router(config-if)# ip address 10.0.1.
Router(config-if)# vrrp 1 ip 10.1.0.10
Router(config-if)# vrrp 1 name vrrp-name-1

Related Commands

Command	Description
vrrp ip	Enables the VRRP on an interface and identifies the IP address of the virtual router.
vrrp name	Links a VRRS client to a VRRP group.

accounting delay (VRRS)

To specify a delay time for sending accounting-off messages for the Virtual Router Redundancy Service (VRRS), use the accounting delay command in VRRS configuration mode. To return to the default accounting delay value, use the no form of this command.

accounting delay seconds

no accounting delay

Syntax Description

seconds

Time, in seconds, to wait before sending accounting-off messages. Range is from 1 to 30. The default is 0.

Command Default

Accounting-off messages for VRRS are sent without delay.

Command Modes

VRRS configuration (config-vrrs)

Command History

Release	Modification
Cisco IOS XE Release 2.6	This command was introduced.
15.1(1)S	This command was integrated into Cisco IOS Release 15.1(1)S.

Usage Guidelines

Use the accounting delay command to control the timing of sending accounting-off messages for VRRS. This command does not apply to accounting-on messages. If the default is specified, this command is not saved to the running configuration and accounting-off messages are sent immediately when the event occurs. Otherwise, a delay of the configured number of seconds is applied.

Examples

The following example shows how to specify a delay time of 10 seconds for sending accounting-off messages for the VRRS:

Router(config)# vrrs vrrp-name-1
Router(config-vrrs)# accounting delay 10

Related Commands

Command	Description
aaa accounting vrrs	Enables AAA accounting of requested services for billing or security purposes when you use VRRS.
accounting method (VRRS)	Enables VRRS accounting for a VRRP group.
attribute list (VRRS)	Specifies additional attributes to include in VRRS accounting-on and accounting-off messages.
vrrs	Enables VRRS and enters VRRS configuration mode.

accounting method (VRRS)

To enable Virtual Router Redundancy Service (VRRS) accounting for a Virtual Router Redundancy Protocol (VRRP) group, use the accounting method command in VRRS configuration mode. To specify the default VRRS accounting method list as the target for VRRS accounting, use the no form of this command.

accounting method {default | accounting-method-list}

no accounting method

Syntax Description

default	Enables VRRS accounting for all VRRP groups.
accounting-method-list	Name of the accounting method list for which VRRS must be enabled.

Command Default

The default VRRS accounting method list is used.

Command Modes

VRRS Configuration (config-vrrs)

Command History

Release	Modification
Cisco IOS XE Release 2.6	This command was introduced.
15.1(1)S	This command was integrated into Cisco IOS Release 15.1(1)S.

Usage Guidelines

Configuring the default keyword does not save it to the running configuration and the VRRS accounting type default method list is automatically applied to the VRRS group being configured. The default keyword also enables VRRS accounting for all VRRP groups.

The valued specified for the accounting-method-list argument must match a named list configured by the aaa accounting vrrscommand. When there is no match, a warning message is displayed. However, the configuration is still saved.

With this approach, you can configure the desired accounting method list using the aaa accounting vrrscommand without configuring the accounting methodcommand again.

Examples

The following example shows how to configure VRRS to use the accounting list named METHOD1:

Router(config)# vrrs VRRS1
Router(config-vrrs)# accounting method METHOD1

Related Commands

Command	Description

attribute list (VRRS)

To specify additional attributes to include in Virtual Router Redundancy Service (VRRS) accounting-on and accounting-off messages, use the attribute list command in VRRS configuration mode. To configure VRRS to send only default attributes in VRRS accounting messages, use the no form of this command.

attribute list list-name

no attribute list

Syntax Description

list-name

Specifies a AAA accounting list, as defined by the aaa attribute list global configuration command.

Command Default

Default attributes are sent in VRRS accounting messages.

Command Modes

VRRS configuration (config-vrrs)

Command History

Release	Modification
Cisco IOS XE Release 2.6	This command was introduced.

Usage Guidelines

Use the attribute list (VRRS) command to specify additional attributes to be included in both VRRS accounting-on and accounting-off messages. Before configuring this command, define a list name using the aaa attribute list global configuration command. If you the enter a list name that is not defined in the aaa attribute list global configuration command, a warning message is displayed. However, this command is still accepted.

The following RADIUS attributes are included in VRRS accounting messages by default:

Attribute 4, NAS-IP-Address
Attribute 26, Cisco VSA Type 1, vrrs
Attribute 40, Acct-Status-Type
Attribute 41, Acct-Delay-Type
Attribute 44 Acct-Session-Id

Examples

The following example configures VRRS to use the AAA accounting list named vrrp-1-attr:

Router(config)# aaa accounting vrrs default start-stop group radius
Router(config)# aaa attribute list vrrp-1-attr
Router(config-attr-list)# attribute type account-delay â10â
Router(config-attr-list)# exit

carrier-delay (tracking)

To enable Enhanced Object Tracking (EOT) to consider the carrier-delay timer when tracking the status of an interface, use the carrier-delay command in tracking configuration mode. To disable EOT from considering the carrier-delay timer when tracking the status of an interface, use the no form of this command.

carrier-delay

no carrier-delay

Command Default

EOT does not consider the carrier-delay timer configured on an interface when tracking the status of the interface.

Command Modes

Tracking configuration (config-track)

Command History

Release	Modification
12.4(9)T	This command was introduced.

Usage Guidelines

If a link fails, by default there is a two-second timer that must expire before an interface and the associated routes are declared as being down. If a link goes down and comes back up before the carrier delay timer expires, the down state is effectively filtered, and the rest of the software on the switch is not aware that a link-down event occurred. You can configure the carrier-delay seconds command in interface configuration mode to extend the timer up to 60 seconds.

When Enhanced Object Tracking (EOT) is configured on an interface, the tracking may detect the interface is down before a configured carrier-delay timer has expired. This is because EOT looks at the interface state and does not consider the carrier delay timer. Use the carrier-delay command in tracking configuration mode to enable tracking to consider the carrier-delay timer configured on an interface.

Examples

The following example shows how to configure the tracking module to wait for the interface carrier-delay timer to expire before notifying clients of a state change:

Router(config)# track 101 interface ethernet1/0 line-protocol
Router(config-track)# carrier-delay

Related Commands
