When the Request VLAN parameter is set to Non-specified, the packets are added with 0 VLAN tags.

Association with other parameters:

You need to set the PW Type parameter to Ethernet Tagged Mode.

Before changing the parameter value of a PW, you need to ensure that the PW is not bound with the service. After the change, you need to bind the PW with the service, and then check whether the parameter value is changed.

Table 3-351  QoS parameters for service access ports

Field

Value Range

Description

Role

For example, Working Source

Displays and specifies the role of a service access port.

Based on different protection types, service access ports can be classified into different roles, for example, working source, working sink, protection source, protection sink, FRR source, and FRR sink.

SAI

-

Displays and specifies the service access port.

Direction

Ingress, Egress

Displays and specifies the direction of a service access port.

  • Ingress indicates the ingress direction of the service.
  • Egress indicates the egress direction of the service.

Bandwidth Limited

Enabled, Disabled

Default: Disabled

Specifies or displays the bandwidth limit.

If you set Bandwidth Limited to Enabled, bandwidth limit is performed based on the specified CIR, PIR, CBS, and PBS.

Committed Information Rate (kbit/s)

1024 to 10000000, Unlimited

Default: 4294967295 (FFFFFFFFFF is invalid)

Committed Information Rate (kbit/s) specifies the committed information rate (CIR) of a queue. When the packet rate is smaller than or equal to the CIR, all packets can be forwarded. If the packet rate is greater than the CIR, some packets are discarded based on specified packet discarding policy.

Recommendations:

The greater CIR, the higher rate of allowed traffic, and the more packets forwarded.

It is recommended that the packet rate is smaller than or equal to the CIR.

Association with other parameters:

This parameter can be set only when Bandwidth Limit is set to Enabled.

If the specified CIR are applied to function points, such as PWs and ports, ensure that the sum of CIRs in all policies applied to the function point is smaller than or equal to the CIR for the function point.

Committed Burst Size (byte)

64-10000000

Default: 4294967295 (FFFFFFFFFF is invalid)

The Committed Burst Size (byte) parameter specifies the committed burst size.

When the bandwidth is insufficient, some packets cannot be forwarded. Therefore, a buffer is required to store these packets for forwarding when the bandwidth is sufficient. CBS is the size of the buffer. When the size of the stored packets is less than the CBS, all these packets can be forwarded.

Recommendations:

If the CBS is small, the buffer easily overflows and some packets are discarded when the bandwidth is insufficient.

The greater the CBS is, the more packets can be buffered when the bandwidth is insufficient, and the less the packet loss ratio is. The greater the CBS, the more serious the delay jitter when packets are forwarded.

For the OptiX OSN equipment, the CBS is reserved and cannot be set.

Peak Information Rate (kbit/s)

64 to 10000000

Default: 4294967295 (FFFFFFFFFF is invalid)

Peak Information Rate (kbit/s) specifies the maximum rate of services allowed by the PIR.

Recommendations:

It is recommended that the PIR be greater than or equal to the (committed information rate) CIR.

Peak Burst Size (byte)

64-10000000

Default: 4294967295 (FFFFFFFFFF is invalid)

The Peak Burst Size (byte) parameter specifies the size of the PBS.

When the bandwidth is insufficient and the CBS buffer is full, the packets that cannot be stored in the CBS buffer are stored in the PBS buffer. When the PBS buffer is full, the extra packets are discarded. The packets stored in the PBS buffer may also fail to be forwarded. The packets whose rates are more than the CIR and less than the PIR attempt to preempt the remaining bandwidth. The packets are forwarded only when they preempt the remaining bandwidth.

Recommendations:

Although the packets in the PBS buffer may also fail to be forwarded, the PBS buffer decreases the packet loss ratio.

The greater the PBS, the less the packet loss ratio, and the more serious the delay jitter when packets are forwarded.

Local QoS Policy

-

Displays the QoS policy at the local end.

Default Forwarding Priority

CS6, CS7, EF, AF1, AF2, AF3, AF4, BE, None

Displays the service forwarding priority.

Different values represent different service classes.
  • CS6-CS7: indicate the highest service class, which is mainly applicable to signaling transmission.
  • EF: indicates the expedited forwarding of service, which is applicable to services (for example, voice services) of low transmission delay and low packet loss rate.
  • AF1-AF4: indicate the ensured forwarding class of service, which is applicable to services that require an ensured rate rather than delay or jitter limit.
  • BE: is applicable to services that do not need to be processed in a special manner.

Default Packet Marking Color

Red, Yellow, Green, None

Displays the default packet marking color.

Based on the labels carried by the packets, different colors are set for marking the packets. Red packets have the highest discarding priority.

Default: Enabled

If you enable APS, you can determine whether to start switching based on the detection mode.

Switching Mode

Single-ended Switching, Dual-ended Switching

The switching mode includes single-ended and dual-ended switching.

  • In the case of single-ended switching, if one end detects a fault, switching occurs at the local end but does not occur at the opposite end.
  • In the case of dual-ended switching, if one end detects a fault, switching occurs at both the local and opposite ends.
NOTE:

PW APS protection supports dual-ended switching.

Revertive Mode

Revertive Mode, Non-revertive Mode

Default: Revertive Mode

The restoration mode includes revertive mode and non-revertive mode.

  • In the non-revertive mode, a service is not reverted back from the protection channel to the working channel even if the working channel returns to normal.
  • In the revertive mode, a service is reverted back from the protection channel to the working channel if the working channel returns to normal within the WTR time.
Switching Revertive Time(min)

1-12

Default: 1

The switching restoration time is the time taken to switch from the protection channel to the working channel after the working channel returns to normal.

NOTE:
In certain situations, the working channel is unstable. In this case, you can set the switching restoration time to prevent a service from being excessively switching between the working and protection channels.
Switching Delay Time(100ms)

0-100

Default: 0

The switching delay time is the time taken to perform switching after the equipment detects a fault. You can set the switching delay time to enable other protection mechanisms to first start switching.

Description

MTU

-

This parameter cannot be set.

BPDU Private Service

Yes, No, BPDU and Service Forwarding

Default: No

Indicates the Bridge Protocol Data Unit (BPDU) packet, a type of Layer 2 protocol packets. BPDU packets are usually used to transmit the Spanning Tree Protocol (STP) and Multiple Spanning Tree Algorithm and Protocol (MSTP) information to calculate the spanning tree. The available options are as follows:

  • Yes: Indicates that the SAI use BPDU packets as service packets and transparently transmits them to the peer.
  • No: Indicates that the function of transparently transmitting BPDU packets is disabled for the SAI and the SAI discards BPDU packets from the user side.
  • BPDU and Service Forwarding: Indicates that the SAI transmits BPDU and service packets to the peer.

In an L2VPN scenario, if the user networks on the two sides both need to run MSTP to calculate the spanning tree, the SAIs on PEs must be capable of transparently transmitting BPDU packets from the user side. Then, BPDU packets from the user side can be used as service packets and transmitted across the L2VPN, and reach the peer user network. If the function of transparently transmitting BPDU packets is disabled, the SAIs discard BPDU packets from the user side. As a result, MSTP between users is unavailable and the spanning tree cannot be calculated.

Indicates the nodes, including source interface, sink interface and the switching node. This parameter cannot be set.

Service Tag

User

Indicates the service tag of E-line service.

User: The outer C/SVLAN tag of user packets is used as the user VLAN tag. When the packets are forwarded, the packet forwarding is based on the user VLAN tag.
