switchport
dot1q-tunnel
priority map
This command copies the inner tag 802.1p value to the outer tag 802.1p value. Use
the no form of this command to use port default priority.
Syntax
[no] switchport dot1q-tunnel priority map
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
◆ The command is configured on a QinQ access port to take packet tag's 1p value
as ingress priority for the S-VLAN. If disabled, the access port always takes the
default 1p priority setting as ingress priority.
◆ When using many-to-one bundling, untagged and priority tagged packets can
be mapped to the S-VLAN with this command. This ensures consistent
treatment of priority tagged packets across the S-VLAN.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#switchport dot1q-tunnel priority map
Console(config-if)#
switchport
dot1q-tunnel
