auto: Configures the interface to negotiate the defense mode by using LLDP.
Usage guidelines
If a device is not assigned to a CND, you cannot configure this command on its interfaces.
The CND settings for an interface take precedence over the global CND settings.
Examples
# Configure defense mode disabled and alternate value 0 for Ten-GigabitEthernet 1/0/1 in the CND
with CNPV 1.
<Sysname> system-view
[Sysname] qcn priority 1 auto
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] qcn port priority 1 admin defense-mode disabled
alternate 0
# Configure Ten-GigabitEthernet 1/0/2 to negotiate the defense mode by using LLDP.
<Sysname> system-view
[Sysname] qcn priority 2 admin
[Sysname] interface ten-gigabitethernet 1/0/2
[Sysname-Ten-GigabitEthernet1/0/2] qcn port priority 2 auto
