8021p-inbound

Function

The 8021p-inbound command maps 802.1p values of upstream VLAN packets in a DiffServ (DS) domain to internal classes of service (CoSs) and colors the packets.

The undo 8021p-inbound command restores the default mapping relationships from 802.1p values to internal CoSs.

By default, the mappings between 802.1p values and CoSs are displayed as Table 1.

Format

8021p-inbound 8021p-value phb service-class [ color ]

undo 8021p-inbound [ 8021p-value ]

Parameters

Parameter Description Value
8021p-value

Specifies the 802.1p value of VLAN packets.

The value is an integer ranging from 0 to 7.

phb service-class

Specifies the CoS value.

The value is an enumerated type and can be case-insensitive EF, AF1, AF2, AF3, AF4, BE, CS6, or CS7.

color

Specifies the color used to mark the packets.

The value can be green, yellow, or red. By default, the packets are colored green.

Usage Guidelines

Usage Scenario

To implement QoS scheduling on the upstream VLAN packets, run the 8021p-inbound command to configure mapping relationships from 802.1p values of the VLAN packets in a DS domain to internal CoSs defined on the router and color the packets. After the DS domain is bound to the inbound interface of packets, QoS performs congestion management and avoidance based on the CoSs mapped to the packets.

If the CoS is CS6, CS7, EF, or BE, the packets can be colored only green.

If 8021p-value is not specified, you can run the undo 8021p-inbound command to restore all default mappings between 802.1p values and CoSs.

If no mapping between 802.1p values and CoSs is specified, the default mappings are adopted.

Table1 Default mappings between 802.1p values and CoSs

802.1p Service Color
0 be green
1 af1 green
2 af2 green
3 af3 green
4 af4 green
5 ef green
6 cs6 green
7 cs7 green

Configuration Impact

If <8021p-value> is not specified, you can run the undo 8021p-inbound command to restore all default mappings between 802.1p values and CoSs.

If no mapping between 802.1p values and CoSs is specified, the default mappings are adopted.

In VS mode, this command is supported only by the admin VS.

Example

# Map the 802.1p value 2 in the upstream VLAN packets to the CoS AF1 and color the packets green.
