Port Priority

Introduction
Typically, networks operate on a best-effort delivery basis, which means that all traffic
has equal priority and an equal chance of being delivered in a timely manner. When
congestion occurs, all traffic has an equal chance of being dropped.
Using Port Priority feature, you can select specific network traffic, and prioritize it
according to its relative importance. Implementing Port Priority in your network makes
network performance more predictable and bandwidth utilization more effective.

CLI Configuration

This command displays the current 802.1p priority
mapping to the service queue.
This command displays the current QoS
scheduling mode of IEEE 802.1p.
This command configures the 802.1p priority
mapping to the service queue.
This command configures the 802.1p priority
mapping to the service queue to default.
This command configures the QoS scheduling
mode to high_first, each hardware queue will
transmit all of the packets in its buffer before
permitting the next lower priority to transmit its
packets.
This command configures the QoS scheduling
mode to Weighted Round Robin.
This command allows the user to specify a default
priority handling of untagged packets received by
the Switch. The priority value entered with this
command will be used to determine which of the
hardware priority queues the packet is forwarded
to. Default: 0.
This command configures the default priority for
the specific port to default (0).
This command displays DiffServ configurations.
This command disables / enables the DiffServ
function.
This command sets the DSCP-to-IEEE 802.1q
mappings.
