AC backup commands

backup-ac

Use backup-ac to specify an IPv4/IPv6 backup AC.

Default command level

2: System level

Parameters

ip ipv4-address: Specifies an IPv4 backup AC.

ip ipv6-address: Specifies an IPv6 backup AC.

Usage guidelines

The backup AC configured in AP template view takes effect on the specified AP.

The backup AC configured in AP group view takes effect on all APs in the AP group.

Examples

# Specify the backup AC at 192.168.1.2 for AP 1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4620i-ACN

[Sysname-wlan-ap-ap1] backup-ac ip 192.168.1.2

# Specify the backup AC at 192.168.1.2 for all APs in the AP group named office.

<Sysname> system-view
