VRRP and VRRP-E virtual router configuration table

The following table replaces the VRRP virtual router table, which uses a slot or port number to index entries. This new table uses the ifindex method to present the configuration and statistics for VRRP and VRRP-E. Each entry in the table describes one VRRP or VRRP-E router.

Description

snVrrpVirRtr2Table

brcdIp.1.2.12.5.1

None

The VRRP virtual router 2 table.

snVrrpVirRtr2Id

brcdIp.1.2.12.5.1.1.1

Syntax: Integer

Read-only

Shows one of the VRIDs configured on this interface. If multiple VRIDs are configured on the interface, there is an entry for each VRID.

snVrrpVirRtr2Ownership

brcdIp.1.2.12.5.1.1.2

Syntax: Integer

Read-write

Indicates the owner of the VRRP router interface. The owner or master router owns the IP addresses associated with the VRID:

  • incomplete(0) - No IP address has been assigned to this VRRP or VRRP-E interface.
  • owner(1) - The owner or the master router is the owner of the VRRP router interface. This applies only to VRRP.
  • backup(2) - The backup router (VRRP or VRRP-E) is the owner of the interface. This is the only value that can be assigned to a VRRP-E router interface.
snVrrpVirRtr2CfgPriority

brcdIp.1.2.12.5.1.1.3

Syntax: Integer

Read-write

Indicates the preferability of a router for becoming the active router for the interface. A higher number indicates a higher priority. If two or more devices are tied with the highest priority, the backup interface with the highest IP address becomes the active router for the VRID.

Valid values: 0 - 255, where:

  • 0 - The master no longer participates in the VRRP and a backup router should transition to be the new master.
  • 255 - The router is the owner.

Default: 100.

snVrrpVirRtr2TrackPriority

brcdIp.1.2.12.5.1.1.4

Syntax: Integer

Read-write

Applies to interfaces that are configured with track ports.

It indicates the priority of the track ports. The higher the number, the higher the priority. Track port priority is always lower than the “snVrrpVirRtrCfgPriority” priority.

This object dynamically adjusts the value of the VRRP and VRRP-E virtual router configuration table object when the track port state first changes from up to down.

Valid values: 1 - 254

snVrrpVirRtr2CurrPriority

brcdIp.1.2.12.5.1.1.5

Syntax: Integer

Read-only

The current VRRP or VRRP-E priority of this Layer 3 Switch for the VRID. The current priority can differ from the configured priority for the following reasons:

  • The VRID is still in the initialization stage and has not become a master or backup yet. In this case, the current priority is 0.
  • The VRID is configured with track ports and the link on a tracked interface has gone down.

A higher number indicates a higher priority.

This object is adjusted dynamically when the tracked port first changes from up to down.

Valid values: 1 - 254

snVrrpVirRtr2HelloInt

brcdIp.1.2.12.5.1.1.6

Syntax: Integer

Read-write

Shows the number of seconds between hello advertisements from the master and the backup.

Valid values: 1 - 84

Default: 1 second.

snVrrpVirRtr2DeadInt

brcdIp.1.2.12.5.1.1.7

Syntax: Integer

Read-write

Applies only to VRRP or VRRP-E backups.

It shows the configured value for the dead interval. The dead interval is the number of seconds that a backup router waits for a hello message from the VRID master before determining that the master is no longer active.

If the Master does not send a hello message before the dead interval expires, the backups negotiate (compare priorities) to select a new master for the VRID.

Valid values: 1 - 84

Default: 0, which means that this object has not been configured.

snVrrpVirRtr2PreemptMode

brcdIp.1.2.12.5.1.1.8

Syntax: Integer

Read-write

Indicates if the backup preempt mode is enabled:

  • disabled(0) - Prohibit preemption.
  • enabled(1) - Allow preemption.

Default: enabled(1)

The backup preempt mode prevents a backup router with a higher VRRP priority from taking control of the VRID from another backup router that has a lower priority, but has already assumed control of the VRID.

snVrrpVirRtr2State

brcdIp.1.2.12.5.1.1.9

Syntax: Integer

Read-only

Specifies the VRRP or VRRP-E router’s interface state:

  • init(0) - Initialization state
  • master(1) - Master state
  • backup(2) - Backup state
snVrrpVirRtr2IpAddrMask

brcdIp.1.2.12.5.1.1.10

Syntax: Octet String

Read-write

The number of IP addresses of this virtual router of this interface.

snVrrpVirRtr2Activate

brcdIp.1.2.12.5.1.1.11

Syntax: Integer

Read-write

Indicates if VRRP or VRRP-E router is enabled:

  • disabled(0) - The router is deactivated.
  • enabled(1) - The router has been activated.
snVrrpVirRtr2BackupInt

brcdIp.1.2.12.5.1.1.12

Syntax: Integer

Read-write

Time interval between backup routers hello message advertisements in seconds. The default is 60 seconds.

snVrrpVirRtr2RowStatus

brcdIp.1.2.12.5.1.1.13

Syntax: Integer

Read-write

Controls the management of the table rows. The following values can be written:

  • delete(3) - Delete the row.
  • create(4) - Create a new row.
  • modify(5) - Modify an existing row.

If the row exists, then a SET with a value of create(4) returns a "bad value" error. Deleted rows are removed from the table immediately.

The following values can be returned on reads:

  • noSuch(0) - No such row.
  • invalid(1) - Row is inoperative.
  • valid(2) - Row exists and is valid.
snVrrpVirRtr2RxArpPktDropCnts

snVrrpVirRtr2RxPriorityZeroFromMasterCnts

brcdIp.1.2.12.5.1.1.20

Syntax: Counter32

Read-only

Shows the count of the virtual router interfaces that received priority zero from the master.

snVrrpVirRtr2RxHigherPriorityCnts

brcdIp.1.2.12.5.1.1.21

Syntax: Counter32

Read-only

Shows the number of packets received by the interface that had a higher backup priority for the VRID than this interface’s backup priority for the VRID.

snVrrpVirRtr2TransToMasterStateCnts

brcdIp.1.2.12.5.1.1.22

Syntax: Counter32

Read-only

Shows the number of times this interface has changed from the master state to the backup state for the VRID.

snVrrpVirRtr2TransToBackupStateCnts

brcdIp.1.2.12.5.1.1.23

Syntax: Counter32

Read-only

Shows the number of times this interface has changed from the master state to the backup state.

snVrrpVirRtr2CurrDeadInt

brcdIp.1.2.12.5.1.1.24

Syntax: Integer32

Read-only

Shows the current dead interval in increments of 100 milliseconds for the virtual router. This is the time period that a backup waits for a hello message from the master before determining that the master is no longer active. If the master does not send a hello message before the dead interval expires, the backups negotiate (compare priorities) to select a new master for the VRID.

snVrrpVirRtr2TrackPortList

brcdIp.1.2.12.5.1.1.25

Syntax: Octet String

Read-write

Specifies the router’s physical track port membership. The membership includes physical ports and virtual ports whose state is to be monitored.

Each port index is an ifIndex. If there are four or more consecutive ifIndexes, then the encoding and decoding scheme is range-based, as follows:

  • Each range prefix with 0000 (2 octets) is not a valid ifIndex.
  • The first two octets in a set of four octets indicate the beginning of the range. The next two octets show the end of the range.
  • IfIndexes that are not in a range are displayed as they are.

For example, you may see the following lists:

  • Port list: 0001..0005 0015 0032..0047

0001..0005 and 0032..0047 show ranges of ifindexes; whereas, 0015 is one ifindex

  • Port list in PDU: 0000 0001 0005 000f 0000 0020 002f

The list contains ifindexes not in a range.

If this object is configured, then the preference level of this interface will be adjusted dynamically depending on the state of the track port. The interface's preference level is reduced by the value of preference level parameter when the track port states first changes from up to down. When the track port returns to the up state, the interface's preference level is increased by the amount specified by the preference level.

snVrrpVirRtr2AdvertiseBackup

brcdIp.1.2.12.5.1.1.26

Syntax: Integer

Read-write

Indicates if the ability for this backup to advertise itself to the current master is enabled:

  • disabled(0)
  • enabled(1)

Default: disabled(0}

snVrrpVirRtr2MasterIpAddr

snVrrpVirRtr2IpAddrCount

brcdIp.1.2.12.5.1.1.28
