Default Setting
The priority is not set, and the default value for untagged frames
received on the interface is zero.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• The precedence for priority mapping is 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.
• This switch provides eight priority queues for each port. It is
configured to use Weighted Round Robin, which can be viewed with
the
show queue bandwidth
command. Inbound frames that do not
have VLAN tags are tagged with the input port’s default ingress user
priority, and then placed in the appropriate priority queue at the
output port. The default priority for all ingress ports is zero.
Therefore, any inbound frames that do not have priority tags will be
placed in queue 0 of the output port. (Note that if the output port is
an untagged member of the associated VLAN, these frames are
stripped of all VLAN tags prior to transmission.)
Example
The following example shows how to set a default priority on port 3 to 5
Console(config)#interface ethernet 1/3
Console(config-if)#switchport priority default 5
