User can configure a default priority for incoming packets on a port. The default-priority acts on incoming packets without a special field which is dscp, ieee-802.1 or inet-precedence.

For example, when trust mode is dscp on an interface, if the incoming packets can‘t match dscp field, these packets will be transmitted by default-priority configured in the interface. Otherwise, these packets will be transmitted by dscp value.  

Traffic class for default priority:

Command Syntax

set class-of–service interface <port> default-priority <default-priority-type> <default-priority-int>

delete class-of–service interface ge-1/1/1 default-priority

Parameter

<port> Gigabit Ethernet Interface. e.g. ge-1/1/1.

<default-priority-type> the type of default priority, which can be dscp, ieee 802.1p or inet-precedence. The default value is ieee 802.1p.

<default-priority-int> the value of default priority, the valid range is 0~7 for ieee-802.1 and inet-precedence, 0~63 for dscp. The default value is 0 for dscp, ieee 802.1p or inet-precedence.

Example

When not configuring any trust mode, configure default priority dscp 16 on ge-1/1/1.

 When trust mode is dscp, configure default priority dscp 16 on ge-1/1/2.
