VRRP configuration commands
NOTE:
•Support of the H3C WX series access controllers for commands may vary by device model. For the
command matrixes, see
About the WX Series Access Controllers Command References .
•At present, the interfaces that VRRP involves can be only LAN interfaces.
display vrrp
Syntax
display vrrp [ verbose ] [ interface interface-type interface-number [ vrid virtual-router-id ] ] [ |{ begin |
exclude | include } regular-expression ]
View
Any view
Default level
1: Monitor level
Parameters
verbose: Displays detailed state information of VRRP groups.
interface interface-type interface-number: Displays VRRP group state information of the specified
interface. The interface-type interface-number arguments specify an interface by its type and number.
vrid virtual-router-id: Displays state information of the specified VRRP group. The virtual-router-id
argument specifies a VRRP group by its group number, which ranges from 1 to 255.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use display vrrp to display the state information of VRRP groups.
If you do not specify verbose, only the brief state information of VRRP group is displayed.
If you specify both an interface and a VRRP group, only the state information of the specified VRRP group
on the interface is displayed. If you only specify an interface, the state information of all the VRRP groups
on the interface is displayed. If you specify neither, the state information of all the VRRP groups on the
router is displayed.

VRRP group. It is displayed only when the router is the master.
Master IP Primary IP address of the interface where the router in master state
resides.
VRRP Track Information
Information about the tracked interface or object. It is displayed only
when the vrrp vrid track or vrrp vrid track interface command is
executed.
Track Interface The interface to be tracked. It is displayed only when the vrrp vrid track
interface command is executed.
Track Object The track entry to be tracked. It is displayed only when the vrrp vrid track
command is executed.
State
State of the tracked interface or track entry.
