Parameters

different: Displays the settings that must be configured differently between the peer devices but are configured the same.

interface: Displays settings configured differently between the interfaces numbered the same on the peer devices.

verbose: Displays the detailed configuration comparison result between the peer devices (settings in all views). If you do not specify this keyword, this command displays the brief configuration comparison result (different settings in the same view).

by-table: Displays the configuration comparison result by table. If you do not specify this keyword, this command displays the settings in the order as they appear in the configuration file.

display mc-configure unsync-info

Use display mc-configure unsync-info to display settings not synchronized to the peer during bulk configuration sync.

Syntax

display mc-configure unsync-info

Views

Any view for multichassis configuration sync

Predefined user roles

network-admin

network-operator

mdc-admin

mdc-operator

Usage guidelines

Bulk configuration sync will not synchronize the settings that must be different between the peers. To know the configuration sync status and view commands that have not been synchronized to the peer, execute the display mc-configure unsync-info command.

Examples

# Display settings not synchronized to the peer during bulk configuration sync.

<Sysname> system-view mc-config

System View: return to User View with Ctrl+Z.

All commands in this view will be synchronized to the peer device.

+[Sysname] mc-configure batch-synchronize

7 commands were not synchronized. To view the detailed information, execute the display mc-configure unsync-info command.

+[Sysname] display mc-configure unsync-info

* indicates an unsynchronized command.

The following commands were not synchronized to the peer device in the last batch synchronization.

*gir snapshot add ipv4routes

*vrrp isolate enable

interface Vlan-interface100

* ip address 1.2.3.4 255.255.255.0

* m-lag system-number 1

Related commands

mc-configure batch-synchronize

mc-configure access-local enable

Use mc-configure access-local enable to permit access of the peer device to the local device via the sync channel.

Use undo mc-configure access-local enable to disallow access of the peer device to the local device via the sync channel.

Syntax

mc-configure access-local enable

undo mc-configure access-local enable

Default

The peer device is permitted to access the peer device via the sync channel.

Usage guidelines

After configuring this command on the local M-LAG member device, you can use the mc-configure switch-to-peer command on the M-LAG peer device to switch from any view for configuration sync to the same view on the local M-LAG member device and configure and manage the local device.

Examples

# Permit access of the peer device to the local device.

<Sysname> system-view

[Sysname] mc-configure access-local enable

Related commands

mc-configure switch-to-peer

mc-configure backup-to-peer

Use mc-configure backup-to-peer to back up the local configuration file to the peer device.

Syntax

mc-configure backup-to-peer local-filename

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

local-filename: Specifies the local configuration file name. The file must be a .cfg file, and the file path cannot exceed 64 characters.

Usage guidelines

To update an M-LAG member device, for example, update the software version or replace the device, you can use the mc-configure backup-to-peer command to back up its configuration file to the M-LAG peer in advance. After the update is completed, you can use the mc-configure get-from-peer command to retrieve the previously saved configuration file from the peer device.

Examples

# Save local configuration file abc.cfg to the peer device.

<Sysname> mc-configure backup-to-peer abc.cfg

Transferring the configuration file. Please wait……

File successfully transferred.

mc-configure batch-synchronize

Use mc-configure batch-synchronize to bulk synchronize configurations to the peer device.

Syntax

mc-configure batch-synchronize

Views

Any view for multichassis configuration sync

Predefined user roles

network-admin

mdc-admin

Usage guidelines

To fast deploy the services that are required to be consistent across the M-LAG member devices, configure the services on one of the M-LAG member device before M-LAG system setup. After the M-LAG system is set up and the peer link comes up, you can execute this command in configuration sync view to bulk synchronize the configurations to the M-LAG peer. For example, if you execute this command in +[Sysname] view, the device will bulk synchronize the configurations in [Sysname] view and its sub-views to the peer device. If you execute this command in [Sysname1-GigabitEthernet1/0/1] view, the device will bulk synchronize the configurations in [Sysname1-GigabitEthernet1/0/1] view and its sub-views to the peer device.

Bulk synchronization synchronizes only configurations that must be consistent between the peers.

Examples

# Bulk synchronize configurations to the peer device.

<Sysname> system-view mc-config

System View: return to User View with Ctrl+Z.

All commands in this view will be synchronized to the peer device.

+[Sysname] mc-configure batch-synchronize

7 commands were not synchronized. To view the detailed information, execute the display mc-configure unsync-info command.

Usage guidelines

To update an M-LAG member device, for example, update the software version or replace the device, you can the mc-configure backup-to-peer command to back up its configuration file to the M-LAG peer in advance. After the update is completed, you can use the mc-configure get-from-peer command to retrieve the previously saved configuration file from the peer device.

Examples

# Retrieve configuration file test from the peer device.

<Sysname> mc-configure get-from-peer test.cfg

Retrieving the configuration file. Please wait……
