VRRP commands The term "interface" in this chapter refers to Layer 3 Ethernet interfaces, and VLAN interfaces. You can configure an Ethernet port as a Layer 3 interface by using the port link-mode route command (see Layer 2—LAN Switching Configuration Guide). IPv4 VRRP commands display vrrp Use display vrrp to display the states of IPv4 VRRP groups.
Vlan2 1 Master 150 100 Simple 1.1.1.1 Table 1 Command output (in standard mode) Field Description Running Mode VRRP operating mode (standard mode). Total number of virtual routers Total number of VRRP groups. Interface Interface where the VRRP group is configured. VRID Virtual router ID (VRRP group number). Status of the router in the VRRP group: • • • • State Master. Backup. Initialize. Inactive. Current priority of the router.
Become Master : 2370ms left Auth Type : None Virtual IP : 1.1.1.11 Master IP : 1.1.1.12 Table 2 Command output (in standard mode) Field Description Running Mode VRRP operating mode (standard mode). Total number of virtual routers Total number of VRRP groups. Interface Interface where the VRRP group is configured. VRID Virtual router ID (VRRP group number). Adver Timer VRRP advertisement sending interval in centiseconds. Admin Status Administrative status: up or down.
Field Description Track entry state: State • Negative. • Positive. • NotReady. Pri Reduced Value by which the priority decreases when the status of the associated track entry becomes negative. Switchover Switchover mode. When the status of the associated track entry becomes negative, the backup immediately becomes the master. display vrrp statistics Use display vrrp statistics to display statistics for IPv4 VRRP groups.

Invalid Pkts Rcvd Number of received packets of invalid packet types.
Syntax reset vrrp statistics [ interface interface-type interface-number [ vrid virtual-router-id ] ] Views User view Predefined user roles network-admin Parameters interface interface-type interface-number: Specifies an interface by its type and number. vrid virtual-router-id: Specifies an IPv4 VRRP group by its virtual router ID in the range of 1 to 7. Usage guidelines • If no interface or VRRP group is specified, this command clears statistics for all IPv4 VRRP groups.
Usage guidelines When the notification function is enabled, the device can send notifications to the destination host. To specify the notification type (inform or trap) and target host, use the snmp-agent target-host command. Examples # Generate notifications as defined in RFC 2787 when the device in a VRRP group receives a VRRP advertisement with the authentication type or key not matching the local configuration.
Syntax vrrp dscp dscp-value undo vrrp dscp Views System view Predefined user roles network-admin Parameters dscp-value: Specifies a DSCP value for VRRP packets, in the range of 0 to 63. The default is 48. Usage guidelines The DSCP value identifies the packet priority during transmission. A greater DSCP value means a higher packet priority. Examples # Configure the DSCP value for VRRP packets as 30.
[Sysname-Vlan-interface10] vrrp version 2 vrrp vrid authentication-mode Use vrrp vrid authentication-mode to configure the authentication mode and the authentication key for an IPv4 VRRP group to send and receive VRRP packets. Use undo vrrp vrid authentication-mode to restore the default.
IMPORTANT: • You can configure different authentication modes and authentication keys for the VRRP groups on an interface. However, members of the same VRRP group must use the same authentication mode and authentication key. • For VRRPv3, this command does not take effect. Examples # Set the authentication mode to simple and the authentication key to Sysname for VRRP group 1 on VLAN-interface 2.
In preemptive mode, a backup takes over as the master and sends VRRP advertisements when it detects that it has a higher priority than the master. The previous master then becomes a backup. This mechanism makes sure the master is always the device with the highest priority.
system-view [Sysname] interface vlan-interface 2 [Sysname-Vlan-interface2] vrrp vrid 1 priority 150 Related commands • display vrrp • vrrp vrid track vrrp vrid shutdown Use vrrp vrid shutdown to disable an IPv4 VRRP group. Use undo vrrp vrid shutdown to restore the default. Syntax vrrp vrid virtual-router-id shutdown undo vrrp vrid virtual-router-id shutdown Default An IPv4 VRRP group is enabled.
Default No source interface is specified for a VRRP group. The interface where the VRRP group resides sends and receives VRRP packets. Views Interface view Predefined user roles network-admin Parameters virtual-router-id: Specifies an IPv4 VRRP group by its virtual router ID in the range of 1 to 7. interface-type interface-number: Specifies an interface by its type and number.
range of 10 to 100, 101 to 200, and 4001 to 4095, the actual values are 100, 200, and 4100, respectively. For VRRPv3, the value of the adver-interval argument that you configured takes effect. Usage guidelines The master in an IPv4 VRRP group periodically sends VRRP advertisements to declare its presence. You can use this command to configure the interval at which the master sends VRRP advertisements.
Parameters virtual-router-id: Specifies an IPv4 VRRP group number in the range of 1 to 7. track-entry-number: Specifies a track entry. The track-entry-number argument is in the range of 1 to 1024. reduced priority-reduced: Reduces the priority of the router in the VRRP group by a specific value when the state of the specified track entry changes to negative. The priority-reduced argument is in the range of 1 to 255.
Default No IPv4 VRRP group is created. Views Interface view Predefined user roles network-admin Parameters virtual-router-id: Specifies an IPv4 VRRP group by its virtual router ID in the range of 1 to 7. virtual-ip virtual-address: Specifies a virtual IP address, which cannot be an all-zero address (0.0.0.0); a broadcast address (255.255.255.255); a loopback address; an IP address of other than Class A, Class B, and Class C; or an invalid IP address (for example, 0.0.0.1).
BFD commands The term "interface" in this chapter collectively refers to Layer 3 interfaces, including VLAN interfaces and Layer 3 Ethernet interfaces. You can set an Ethernet port as a Layer 3 interface by using the port link-mode route command (see Layer 2—LAN Switching Configuration Guide). bfd authentication-mode Use bfd authentication-mode to configure the BFD authentication mode for single-hop BFD control packets. Use undo bfd authentication-mode to restore the default.

Examples # Configure the minimum interval for receiving BFD echo packets on VLAN-interface 11 as 500 milliseconds.
Examples # Configure the minimum interval for receiving single-hop BFD control packets on VLAN-interface 11 as 500 milliseconds. system-view [Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] bfd min-receive-interval 500 bfd min-transmit-interval Use bfd min-transmit-interval to configure the minimum interval for transmitting single-hop BFD control packets.
