Parameters
critical-vlan-id: Specifies the ID of the 802.1X critical VLAN on the port. The value range for the VLAN
ID is 1 to 4094. Make sure the VLAN has been created.
Usage guidelines
An 802.1X critical VLAN accommodates users who fail 802.1X authentication because all the
RADIUS servers in their ISP domains are unreachable. Users in the critical VLAN can access a
limited set of network resources depending on the configuration.
You cannot specify a VLAN as both a super VLAN and an 802.1X critical VLAN on a port. For more
information about super VLANs, see Layer 2—LAN Switching Configuration Guide.
To delete a VLAN that has been configured as an 802.1X critical VLAN, you must first use the undo
dot1x critical vlan command.
Examples
# Specify VLAN 100 as the 802.1X critical VLAN on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] dot1x critical vlan 100

Parameters
string: Specifies a set of 1 to 16 domain name delimiters for 802.1X users. No space is required
between delimiters. Available delimiters include the at sign (@), backslash (\), dot (.), and forward
slash (/). If you want to use backslash (\) as the domain name delimiter, you must enter the escape
character (\) along with the backslash (\) sign.
Usage guidelines
Any character in the configured set can be used as the domain name delimiter for 802.1X
authentication users. Usernames that include domain names can use the format of
username@domain-name,
username/domain-name.
domain-name\username,
