adjust-cost enable
Use adjust-cost enable to enable the HA group to adjust the link cost for the specified routing protocol on the standby device.
Use undo adjust-cost enable to disable the HA group from adjusting the link cost for the specified routing protocol on the standby device.
Syntax
adjust-cost { bgp | isis | ospf | ospfv3 } enable { absolute [ absolute-cost ] | increment [ increment-cost ] }
undo adjust-cost { bgp | isis | ospf | ospfv3 } enable
Default
The HA group does not adjust the link cost for the specified routing protocol on the standby device.
Views
HA group view
Predefined user roles
network-admin
Parameters
bgp: Specifies the BGP protocol.
isis: Specifies the IS-IS protocol.
ospf: Specifies the OSPF protocol.
ospfv3: Specifies the OSPFv3 protocol.
absolute [ absolute-cost ]: Specifies an absolute cost in the range of 1 to 65535. The default value is 65500. If you specify this option, the standby device will advertise an absolute link cost for the specified routing protocol.
increment [ increment-cost ]: Specifies an increment cost in the range of 1 to 65535. The default value is 100. If you specify this option, the standby device will advertise the original link cost plus this increment cost for the specified routing protocol.
Usage guidelines
In an HA group, the routing protocols on the HA group member devices advertise link cost according to their respective operation mechanisms. This command allows you to enable the routing protocols to advertise link cost modified as configured. The active device still uses the original link cost advertisement method.
To ensure switchover of both uplink and downlink traffic to the new active device, configure this command with the same parameters on both HA group member devices.
In dual-active mode, both devices advertise link cost according to the operation mechanisms of the running routing protocols. When one device is faulty and becomes the standby device, it will advertise link cost modified as configured.
To enable the feature for multiple routing protocols, execute this command multiple times by specifying the protocols.
If you execute the command multiple times for a specific routing protocol, the most recent configuration takes effect.
Examples
# Enable the HA group to adjust OSPF link cost on the standby device by specifying an absolute value of 6000.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] adjust-cost ospf enable absolute 6000
backup-mode
Use backup-mode to configure the HA mode.
Use undo backup-mode to restore the default.
Syntax
backup-mode dual-active
undo backup-mode
Default
The HA mode is active/standby.
Views
HA group view
Predefined user roles
network-admin
Usage guidelines
The HA group supports active/standby mode and dual-active mode. In active/standby mode, only the active device processes services. In dual-active mode, both devices process services.
Changing the dual-active mode to active/standby mode might affect services. Make sure you understand the potential impact before performing the operation.
Examples
# Configure the dual-active mode.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] backup-mode dual-active
configuration auto-sync enable
Use configuration auto-sync enable to enable automatic configuration synchronization.
Use undo configuration auto-sync enable to disable automatic configuration synchronization.
Syntax
configuration auto-sync enable
undo configuration auto-sync enable
Default
Automatic configuration synchronization is disabled.
Views
HA group view
Predefined user roles
network-admin
Usage guidelines
The automatic configuration synchronization feature synchronizes existing configuration on the primary device in bulk to the secondary device. Consequent synchronization for added, deleted, or modified configuration will be performed in real time.
If the amount of configuration to be synchronized is large, bulk synchronization might take one to two hours.
Examples
# Enable automatic configuration synchronization.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] configuration auto-sync enable
configuration manual-sync
Use configuration manual-sync to manually synchronize the configuration of the primary device to the secondary device.
Syntax

Usage guidelines
This command does not take effect when bulk configuration backup is in progress. To view the backup progress, execute the display remote-backup-group status command.
Examples
# Manually synchronize the configuration of the primary device to the secondary device.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] configuration manual-sync
Related commands
display remote-backup-group status
configuration sync-check
Use configuration sync-check to enable configuration consistency check.
Use undo configuration sync-check to restore the default.
Syntax
configuration sync-check [ interval interval ]
undo configuration sync-check
Default
Configuration consistency check is disabled.
Views
HA group view
Predefined user roles
network-admin
Parameters
interval interval: Specifies the configuration consistency check interval, in the range of 1 to 168 hours. The default value is 24.
Usage guidelines
The HA group verifies configuration consistency between the HA group member devices to avoid service interruption upon active/standby switchover. If a device detects configuration inconsistency, it generates a log for you to manually synchronize configuration.
Examples
# Enable configuration consistency check and set the check interval to 120 hours.
<Sysname>system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] configuration sync-check interval 120
Related commands
configuration manual-sync
data-channel
Use data-channel to configure an HA data channel.
Use undo data-channel to restore the default.
Syntax
data-channel interface interface-type interface-number
undo data-channel
Default
No HA data channel is configured.
Views
HA group view
Predefined user roles
network-admin
Parameters
interface interface-type interface-number: Specifies an interface by its type and number to set up a data channel between the HA group member devices.
Usage guidelines
The HA group member devices use the interface specified in the command to set up an HA data channel. The data channel transmits only backup packets and the packets that require transparent transmission.
The data channel is a Layer 2 channel that can transverse only Layer 2 switches.
Examples
# Set up an HA data channel using interface GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] data-channel interface gigabitethernet 1/0/1
delay-time
Use delay-time to enable traffic switchover upon failure recovery.
Use undo delay-time to disable traffic switchover upon failure recovery.
Syntax
delay-time delay-time
undo delay-time
Default
Traffic switchover upon failure recovery is disabled.
Views
HA group view
Predefined user roles
network-admin
Parameters
delay-time: Specifies the switchover delay time in the range of 1 to 1440 minutes.
Usage guidelines
After an active/standby switchover in an HA group, if the original active device recovers, traffic will not be switched back by default. Perform this task to enable traffic switchover to the original active device upon failure recovery. You can set a delay timer to ensure smooth service switchover.
In dual-active mode, you must configure this command to ensure that both devices can operate after the failure is recovered.
Examples
# Enable traffic switchover upon failure recovery and set the switchover delay time to two minutes.
<Sysname>system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] delay-time 2
device-role
Use device-role to configure the HA role.
Use undo device-role to restore the default.
Syntax
device-role { primary | secondary }
undo device-role
Default
The HA role is not configured.
Views
HA group view
Predefined user roles
network-admin
Parameters
primary: Assigns the primary role to the device.
secondary: Assigns the secondary role to the device.
Usage guidelines
The HA group backs up important configuration from the primary device to the secondary device to prevent service interruption when an active/standby switchover occurs. The configuration on the secondary device is overwritten. The unidirectional backup mechanism avoids configuration conflicts, especially in dual-active mode, and ensures configuration consistency on the HA group member devices.
The HA group must contain one primary device and one secondary device.
As a best practice, configure service features on the primary device.
Examples
# Assign the primary role to the device.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] device-role primary

Predefined user roles
network-admin
Parameters
ipv4-address: Specifies the peer IPv4 address for setting up the HA control channel.
port port-number: Specifies a port by its number used for establishing TCP connection. The value range for the port-number argument is 1024 to 65535, and the default value is 60064.
Usage guidelines
The HA control channel transmits data by using packets, including HA group status packets, configuration consistency check packets, and configuration synchronization packets. Each member device compares the specified local and peer IP address to determine the device role for setting up the control channel. The device with higher IP address acts as the server to listen for TCP connection requests, and the other device acts as the client to initiate the TCP connection.
If the port number is configured on the server, the port provides services for the client. If the port number is configured on the client, the port serves as the destination port to establish TCP connection to the server. The source port is randomly generated on the client.
You can specify only one peer IP address with the same port number on the HA group member devices.
You can configure a remote IPv4 address or a remote IPv6 address, but not both.
Examples
# Configure the peer IPv4 address and port number as 1.1.1.1 and 4456 for setting up the HA control channel.

Parameters
ipv6-address: Specifies the peer IPv6 address for setting up the HA control channel.
port port-number: Specifies a port by its number used for establishing TCP connection. The value range for the port-number argument is 1024 to 65535, and the default value is 60064. Make sure the port number is not in use.
Usage guidelines
The HA control channel transmits data by using packets, including HA group status packets, configuration consistency check packets, and configuration synchronization packets. Each member device compares the specified local and peer IPv6 address to determine the device role for setting up the control channel. The device with higher IPv6 address acts as the server to listen for TCP connection requests, and the other device acts as the client to initiate the TCP connection.
If the port number is configured on the server, the port provides services for the client. If the port number is configured on the client, the port serves as the destination port to establish TCP connection to the server. The source port is randomly generated on the client.
You can specify only one peer IPv6 address with the same port number on the HA group member devices.

Syntax
switchover request
Views
HA group view
Predefined user roles
network-admin
Usage guidelines
If you want to replace components or upgrade software on the current active device, you can execute this command to switch services to the standby device.
This command applies only when the HA group operates in active/standby mode.
In an HA group and VRRP associated network, executing this command might cause temporary virtual IP address conflict in the VRRP group, which is considered a normal condition.
Examples
# Perform an active/standby switchover.
<Sysname> system-view
[Sysname] remote-backup group
[Sysname-remote-backup-group] switchover request
track
Use track to associate the HA group with Track.

Parameters
track-entry-number: Specifies a track entry by its ID in the range of 1 to 1024.
Usage guidelines
Use this command to associate the HA group with Track to monitor links. If one of the monitored track entries becomes Negative, the HA group performs an active/standby switchover and switches traffic to the new active device to ensure service continuity. For more information about Track, see High Availability Configuration Guide.
To associate the HA group with multiple track entries, execute this command multiple times.
Examples
# Associate the HA group with track entries 1 and 2.

Predefined user roles
network-admin
Parameters
interface-type interface-number: Specifies an interface by its type and number. You can specify a Layer 2 Ethernet interface in the current software version. If you do not specify this argument, the undo form of the command removes the monitoring for all interfaces.
Usage guidelines
Use this command to enable the HA group to monitor the interfaces connecting the uplink and downlink devices. The monitored interfaces can forward packets only when they are all up. If any of the monitored interfaces goes down, none of them will be able to forward packets.
To enable the HA group to monitor multiple interfaces, execute this command multiple times.
The track vlan, track interface, and track commands are mutually exclusive.
The HA group does not support monitoring member ports of aggregate interfaces.
Examples
# Enable the HA group to monitor interfaces GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2.
<Sysname> system-view

Views
HA group view
Predefined user roles
network-admin
Parameters
vlan-id: Specifies a VLAN by its ID in the range of 1 to 4094. If you do not specify this argument, the undo form of the command removes the monitoring for all VLANs.
Usage guidelines
Use this command to enable the HA group to monitor the VLANs of the uplink and downlink devices. The monitored VLANs are active and the member ports can forward packets only when the member ports are all up. If any of the member ports goes down, none of them will be able to forward packets, and all the monitored VLANs will become inactive.
In active/standby mode, the state of monitored VLANs is active on the primary device and inactive on the secondary device.
In dual-active mode, the state of monitored VLANs is active on both HA group member devices.
Do not enable the HA group to monitor VLAN 1 (to which all access ports belong by default). This restriction prevents an unused interface in down state from interrupting operation of other interfaces in VLAN 1.
To enable the HA group to monitor multiple VLANs, execute this command multiple times.
The track vlan, track interface, and track commands are mutually exclusive.
Examples
# Enable the HA group to monitor VLAN 10.

virtual-ip virtual-address: Specifies a virtual IPv6 address. If you do not specify this option, the undo vrrp ipv6 vrid command removes all virtual IPv6 addresses from the specified IPv6 VRRP group.
link-local: Specifies a link-local address as the virtual IPv6 address.
active: Associates the IPv6 VRRP group with the HA group by adding the device to the IPv6 VRRP active group. The initial role of the device is master.
standby: Associates the IPv6 VRRP group with the HA group by adding the device to the IPv6 VRRP standby group. The initial role of the device is backup.
Usage guidelines
You can execute this command multiple times to assign multiple virtual IPv6 addresses to an IPv6 VRRP group. An IPv6 VRRP group can have a maximum of 16 virtual IPv6 addresses.
The first virtual IPv6 address that you assign to an IPv6 VRRP group must be a link-local address, and it must be removed last.
An IPv6 VRRP group can have only one link-local address as its virtual IPv6 address. For an IPv6 VRRP group to work correctly, you must also assign it a global unicast address as a virtual IPv6 address.
The virtual IPv6 address of an IPv6 VRRP group and the downlink interface IPv6 address of the VRRP group members must be on the same subnet. Otherwise, the hosts on the subnet might fail to access external networks.
You cannot associate an IPv6 VRRP group operating in load balancing mode with the HA group.
You can assign multiple virtual IPv6 addresses to an IPv6 VRRP group associated with the HA group. Make sure the interfaces in the IPv6 VRRP group do not own the virtual IPv6 addresses.
You cannot associate an IPv6 VRRP group with both the HA group and Track.
To modify the settings for the command, first execute the undo form of the command, and then execute the vrrp ipv6 vrid command again.
Examples
# Create IPv6 VRRP group 1, assign virtual IPv6 address fe80::10 to the VRRP group, and assign the device to the VRRP active group. Then assign virtual IPv6 address 1::10 to the VRRP group.

vrrp vrid
Use vrrp vrid to create an IPv4 VRRP group and assign a virtual IP address to it, or to assign a virtual IP address to an existing IPv4 VRRP group.
Use undo vrrp vrid to remove all configurations of an IPv4 VRRP group, or to remove a virtual IP address from an IPv4 VRRP group.
Syntax
vrrp vrid virtual-router-id virtual-ip virtual-address { active | standby }
undo vrrp vrid virtual-router-id [ virtual-ip [ virtual-address ] ]
Default
No IPv4 VRRP groups exist.

Parameters
virtual-router-id: Specifies an IPv4 VRRP group by its virtual router ID in the range of 1 to 255.
virtual-ip virtual-address: Specifies a virtual IP address. You cannot specify the virtual IP address as any of the following IP addresses:
· All-zero address (0.0.0.0).
· Broadcast address (255.255.255.255).
· Loopback address.
· IP address of other than Class A, Class B, and Class C.
· Invalid IP address (for example, 0.0.0.1).
If you do not specify the virtual-address argument, the undo vrrp vrid command removes all virtual IP addresses from the specified IPv4 VRRP group.
active: Associates the VRRP group with the HA group by adding the device to the VRRP active group. The initial role of the device is master.
standby: Associates the VRRP group with the HA group by adding the device to the VRRP standby group. The initial role of the device is backup.

You cannot associate a VRRP group operating in load balancing mode with the HA group.
For VRRP to operate correctly, make sure a virtual IP address of an IPv4 VRRP group is not the IP address of any interface in the VRRP group.
You can assign multiple virtual IPv4 addresses to an IPv4 VRRP group associated with the HA group. Make sure the interfaces in the IPv4 VRRP group do not own the virtual IPv4 addresses.
You cannot associate a VRRP group with both the HA group and Track.
To modify the settings for the command, first execute the undo form of the command, and then execute the vrrp vrid command again.
