no switchport priority default
default-priority-id - The priority number for untagged ingress traffic.

Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• The precedence for priority mapping is IP Port, IP Precedence or IP
DSCP, and default switchport priority.
• The default priority applies for an untagged frame received on a port set
to accept all frame types (i.e, receives both untagged and tagged frames).
This priority does not apply to IEEE 802.1Q VLAN tagged frames. If
the incoming frame is an IEEE 802.1Q VLAN tagged frame, the IEEE
802.1p User Priority bits will be used.
