VSRP commands
VSRP basic commands
backup id
Use backup id to specify a backup ID for a VSRP instance.
Use undo backup id to restore the default.
Syntax
backup id backup-id peer peer-name
undo backup id
Default
A VSRP instance has no backup ID.
Views
VSRP instance view
Predefined user roles
network-admin
Parameters
backup-id: Specifies a VSRP instance by its backup ID in the range of 1 to 1024.
peer-name: Specifies a VSRP group by its name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
A VSRP instance can be associated with only one VSRP group. The backup ID uniquely identifies a VSRP instance in a VSRP group.
You must specify the same backup ID for a VSRP instance on both devices in a VSRP group.
When you specify a backup ID for a VSRP instance, make sure the following conditions are met:
· The associated VSRP group already exists.
· The backup ID is unique in the VSRP group.
To specify a new backup ID for a VSRP instance, first execute the undo form of the command to remove the existing backup ID setting.
Examples
# Specify the backup ID of VSRP instance aaa as 5 in VSRP group pname.
<Sysname> system-view
[Sysname] vsrp instance aaa
[Sysname-vsrp-instance-aaa] backup id 5 peer pname
backup mode
Use backup mode to set the backup mode for a VSRP instance.
Use undo backup mode to restore the default.
Syntax
backup mode { cold | hot [ dual-active ] }
undo backup mode
Default
A VSRP instance operates in hot backup mode.
Views

Predefined user roles
network-admin
Parameters
cold: Specifies cold backup mode.
hot: Specifies hot backup mode.
dual-active: Specifies dual-active hot backup mode. To specify single-active hot backup mode, do not specify this keyword together with the hot keyword. The dual-active keyword is supported only in the VSRP and S-Trunk collaboration network. Do not configure this keyword in other networks.
Usage guidelines
In cold backup mode, two devices deployed with VSRP provide only device-level service redundancy. Service data is backed up between the master and backup devices. When a switchover occurs, the new master device might experience a temporary service interruption due to the lack of service data. This mode is applicable to the scenarios that are not sensitive to temporary service interruptions.
In hot backup mode, the backup device issues backup information to the data plane immediately upon receiving the information from the master. This allows the VSRP instance to perform a fast master and backup switchover to enable the backup to forward packets when the master fails. VSRP provides the following hot backup modes:
· Dual-active hot backup mode—Both the master and backup devices are active to load share traffic.
· Single-active hot backup mode—The master device is active to process service traffic, and the backup device takes over when the master device fails.
Examples
# Set VSRP instance aaa to operate in hot backup mode.
<Sysname> system-view
[Sysname] vsrp instance aaa
[Sysname-vsrp-instance-aaa] backup mode hot
bind s-trunk
Use bind s-trunk to bind a VSRP instance to a smart trunk member interface.
Use undo bind s-trunk to restore the default.
Syntax
bind s-trunk s-trunk-id interface route-aggregation interface-number
undo bind s-trunk
Default
A VSRP instance is not bound to any smart trunk member interface.
Views

Predefined user roles
network-admin
Parameters
s-trunk-id: Specifies a smart trunk ID in the range of 1 to 128.
interface route-aggregation interface-number: Specifies a Layer 3 aggregate interface in the smart trunk by its interface number.
Usage guidelines
A VSRP instance is bound to a smart trunk to determine the device role (master or backup) in the VSRP instance. You can bind a VSRP instance to only one smart trunk.
A VSRP instance is in initialized state in one of the following conditions:
· The Layer 3 aggregate interface bound to the VSRP instance is not in the specified smart trunk.
· The specified smart trunk does not exist.
If you execute the following commands multiple times for a VSRP instance, the most recent configuration takes effect:
· bind interface
· bind s-trunk
Examples
# Bind VSRP instance aaa to Route-Aggregation 1 in smart trunk 1.
<Sysname> system-view
[Sysname] vsrp instance aaa
[Sysname-vsrp-instance-aaa] bind s-trunk 1 interface route-aggregation 1

Parameters
ipv6: Specifies IPv6 addresses. To specify IPv4 addresses, do not specify this keyword.
peer-ip-address: Specifies the IPv4 address of the peer.
local local-ip-address: Specifies the IPv4 address of the local device.
port port-id: Specifies the TCP port number for establishing the control channel. The value range is 1024 to 65535 and the default is 60032. The specified port number cannot be one that is in use. To view the TCP port numbers in use, execute the display [ ipv6 ] tcp command.
Usage guidelines
You must specify different unicast IP addresses for the peer device and the local device in a VSRP group. The IP addresses cannot be all zeros or loopback addresses.
If you have multiple VSRP groups, make sure their IP address pairs are unique.
You cannot configure both IPv4 and IPv6 VSRP channels for the same VSRP peer. To change the TCP parameters for VSRP channel establishment, first execute the undo form of the command to remove the existing VSRP channels.
Examples
# Specify channel establishment parameters for VSRP group pname. Set the local IPv4 address to 11.0.0.2, the peer IPv4 address to 10.0.0.1, and the TCP port number for the control channel to 7000.

Predefined user roles
network-admin
Parameters
track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.
Usage guidelines
By default, a VSRP group can detect the state of the failover link based only on the state of the TCP control channel.
You can associate a VSRP group with a track entry to identify the state of the failover link.
· When the track entry is in Positive or NotReady state, a device in the VSRP group attempts to establish a TCP control channel to the peer.
· When the track entry changes to Negative state, the device terminates the TCP control channel.
A VSRP group takes effect only when a TCP control channel is established.
For more information about track entries, see High Availability Configuration Guide.

Predefined user roles
network-admin
Parameters
vsrp-instance-name: Specifies a VSRP instance by its name, a case-sensitive string of 1 to 31 characters.
apply sub-interface: Associates the specified VSRP instance with ARP on all subinterfaces that do not have a VSRP instance association. If you do not specify the apply sub-interface keyword, this command does not associate the VSRP instance with the subinterfaces of the specified interface. This keyword is supported only by main interfaces.
Usage guidelines
This command enables the master to back up the ARP entries of the interface to the backup in real time through the data channel of VSRP. When the master fails or its links fail, the backup can take over to forward traffic immediately without traffic loss.
On an interface, the time taken to create or remove a VSRP instance association for ARP increases with the number of entries to synchronize. You cannot execute this command again before the creation or removal operation is complete.
To modify the VSRP instance association for ARP on an interface, first remove the existing association.
Examples
# Associate ARP with VSRP instance vsrp 1 on GigabitEthernet 1/0/6.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/6
[Sysname-GigabitEthernet1/0/6] arp vsrp-instance vsrp1
Related commands
arp vsrp-port
arp vsrp-port

Predefined user roles
network-admin
Parameters
port-number: Specifies a TCP port number in the range of 1 to 65535. The specified port number cannot be used by other services or be a well-known port.
Usage guidelines
To back up ARP entries, the master must establish a TCP data channel with the backup. You can use this command to change the TCP port number for establishing the data channel.
Examples
# Specify TCP port 20000 for VSRP to establish data channels for ARP service backup.
<Sysname> system-view
[Sysname] arp vsrp-port 20000

Predefined user roles
network-admin
Parameters
vsrp-instance-name: Specifies a VSRP instance by its name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
You can specify a nonexistent VSRP instance for this command, but this command takes effect only after the VSRP instance is created.
You can associate an interface or subinterface with only one VSRP instance.
You can associate a VSRP instance with one interface or multiple subinterfaces on the same interface.
If a VSRP instance has been associated with one interface, you must remove the VSRP instance from that interface before you can specify it on another interface.
Removing or configuring a VSRP instance association will cause the removal of multicast group information for offline users.
Examples
# Associate GigabitEthernet 1/0/6 with VSRP instance vsrp1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/6
[Sysname-GigabitEthernet1/0/6] igmp vsrp-instance vsrp1
igmp vsrp-load-balance
Use igmp vsrp-load-balance to enable VSRP load sharing on an IGMP-enabled interface.
Use undo igmp vsrp-load-balance to restore the default.
Syntax
igmp vsrp-load-balance [ no-restore | restore-delay delay-time ]
undo igmp vsrp-load-balance
Default
VSRP load sharing is disabled on an IGMP-enabled interface. Only the master device forwards multicast traffic.

Predefined user roles
network-admin
Parameters
no-restore: Disables multicast traffic fallback upon recovery of the failed peer device. If you specify this option, the local device will continue forwarding all multicast traffic after the peer device recovers from failure.
restore-delay delay-time: Sets the delay in seconds for switching multicast traffic to the local device after it recovers from failure. The value range for the delay-time argument is 1 to 65535, and the default value is 180.
Usage guidelines
In a VSRP group, the master device by default forwards all multicast traffic. After you enable VSRP load sharing, the master and backup devices forward multicast traffic for odd multicast group addresses and even multicast group addresses, respectively.
If you do not specify any parameters, the multicast traffic fallback delay is set to the default value. After recovering from failure, the local device must wait 180 seconds before it can forward multicast traffic.
You must configure the same VSRP load sharing settings on the two member devices in the same VSRP group.
If you configure VSRP load sharing on a subinterface, follow these restrictions:
· Make sure the subinterface and its main interface are associated with the same VSRP instance.
· Configure VSRP load sharing on the main interface. Otherwise, VSRP load sharing does not take effect on the subinterface.
If the member devices in a VSRP group fail simultaneously, the member device that first recovers forwards all multicast traffic. When the other member device also recovers, it loads share multicast traffic immediately, whether you enable VSRP load sharing or not. In this situation, transient multicast traffic loss will occur.
In a VSRP group, if a non-direct uplink fails on a member device, the other member device forwards all multicast traffic. When the non-direct uplink recovers, the downstream VSRP member device loads share multicast traffic immediately, whether you enable VSRP load sharing or not. In this situation, transient multicast traffic loss will occur.
When you set the multicast traffic fallback delay, follow these restrictions and guidelines:
· To prevent absence of multicast forwarding entries from causing multicast traffic loss, increase this delay.
· To prevent a recovered member device from being idle, decrease this delay.
· Make sure this delay is longer than the maximum response time for IGMP general queries (configurable with the igmp max-response-time command).
· If you do not set the maximum response time for IGMP general queries, set this delay to be longer than 60 seconds.
During multicast traffic fallback, multicast traffic loss or duplication might occur. In an environment that requires high availability of multicast services, disable multicast traffic fallback.

Usage guidelines
Enable IGMP data synchronization if you are not sure whether the master and the backup can both receive IGMP packets.
Disable IGMP data synchronization if the master and the backup can both receive IGMP packets. For example, you can disable IGMP data synchronization if you have not configured IPoE, PPP, or portal authentication for multicast users.
The synchronized IGMP data will age out after you disable IGMP data synchronization.
