|
any |
Specifies to match all packets. |
|
customer-dot1p 8021p-list |
Specifies to match packets by 802.1p precedence of the customer network. The 8021p-list argument is a list of CoS values, in the range of 0 to 7. |
|
customer-vlan-id vlan-id-list |
Specifies to match the packets of specified VLANs of user networks. The vlan-id-list argument specifies a list of VLAN IDs, in the form of vlan-id to vlan-id or multiple discontinuous VLAN IDs (separated by space). You can specify up to eight VLAN IDs for this argument at a time. VLAN ID is in the range 1 to 4094. |
|
destination-mac mac-address |
Specifies to match the packets with a specified destination MAC address. |
|
dscp dscp-list |
Specifies to match packets by DSCP precedence. The dscp-list argument is a list of DSCP values in the range of 0 to 63. |
|
ip-precedence ip-precedence-list |
Specifies to match packets by IP precedence. The ip-precedence-list argument is a list of IP precedence values in the range of 0 to 7. |
|
protocol protocol-name |
Specifies to match the packets of a specified protocol. The protocol-name argument can be IP. |
|
service-dot1p 8021p-list |
Specifies to match packets by 802.1p precedence of the service provider network. The 8021p-list argument is a list of CoS values in the range of 0 to 7. |
|
service-vlan-id vlan-id-list |
Specifies to match the packets of the VLANs of the operator’s network. The vlan-id-list argument is a list of VLAN IDs, in the form of vlan-id to vlan-id or multiple discontinuous VLAN IDs (separated by space). You can specify up to eight VLAN IDs for this argument at a time. VLAN ID is in the range of 1 to 4094. |
|
source-mac mac-address |
Specifies to match the packets with a specified source MAC address. |
The matching criteria listed below must be unique in a traffic class with the operator being AND. Therefore, even though you can define multiple if-match clauses for these matching criteria or input multiple values for a list argument (such as the 8021p-list argument) listed below in a traffic class, avoid doing that. Otherwise, the QoS policy referencing the class cannot be applied to interfaces successfully.
l customer-dot1p 8021p-list
l customer-vlan-id vlan-id-list
l destination-mac mac-address (you cannot specify a MAC address list)
l dscp dscp-list
l ip-precedence ip-precedence-list
l service-dot1p 8021p-list
l service-vlan-id vlan-id-list
l source-mac mac-address (you cannot specify a MAC address list)
To create multiple if-match clauses or specify multiple values for a list argument for any of the matching criteria listed above, ensure that the operator of the class is OR.
A QoS policy referencing the clause listed below cannot be applied in the outbound direction.
l customer-dot1p 8021p-list
l customer-vlan-id vlan-id-list
l ip-precedence ip-precedence-list
Description
Use the if-match command to define a match criterion.
Use the undo if-match command to remove the match criterion.
Use the if-match not command to define a criterion for matching traffic not conforming to the specified criterion.
Use the undo if-match not command to remove the criterion for matching traffic not conforming to the specified criterion.
When defining match criteria, note the following:
1) Define an ACL-based match criterion
l If the ACL referenced in the if-match command does not exist, the class cannot be applied to hardware.
l For a class, you can reference an ACL twice by its name and number respectively with the if-match command.
2) Define a criterion to match a destination MAC address or a source MAC address
l You can configure multiple destination MAC address match criteria in a class.
3) Define a criterion to match DSCP values
l You can configure multiple DSCP match criteria in a class. All the defined DSCP values are arranged in ascending order automatically.
l You can configure up to eight DSCP values in one command line. If multiple identical DSCP values are specified, the system considers them as one. If a packet matches one of the defined DSCP values, it is considered matching the if-match clause.
l To delete a criterion matching DSCP values, the specified DSCP values must be identical with those defined in the rule (sequence may be different).
4) Define a criterion to match the 802.1p precedence values of the customer network or service provider network
l You can configure multiple 802.1p precedence match criteria in a class. All the defined 802.1p values are arranged in ascending order automatically.
l You can configure up to eight 802.1p precedence values in one command line. If the same 802.1p precedence value is specified multiple times, the system considers them as one. If a packet matches one of the defined 802.1p precedence values, it is considered matching the if-match clause.
l To delete a criterion matching 802.1p precedence values, the specified 802.1p precedence values in the command must be identical with those defined in the criterion (sequence may be different).
5) Define a criterion to match IP precedence values
l You can configure multiple IP precedence match criteria in a class. The defined IP precedence values are arranged automatically in ascending order.
l You can configure up to eight IP precedence values in one command line. If the same IP precedence is specified multiple times, the system considers them as one. If a packet matches one of the defined IP precedence values, it is considered matching the if-match clause.
l To delete a criterion matching IP precedence values, the specified IP precedence values in the command must be identical with those defined in the criterion (sequence may be different).
6) Define a criterion to match customer network VLAN IDs or service provider network VLAN IDs
l You can configure multiple VLAN ID match criteria in a class. The defined VLAN IDs are automatically arranged in ascending order.
l You can configure multiple VLAN IDs in one command line. If the same VLAN ID is specified multiple times, the system considers them as one. If a packet matches one of the defined VLAN IDs, it is considered matching the if-match clause.
l To delete a criterion matching VLAN IDs, the specified VLAN IDs in the command must be identical with those defined in the criterion (sequence may be different).

Description
Use the qos trust command to configure the trusted precedence type on an interface.
Use the undo qos trust command to restore the default.
By default, the port priority is trusted.
When packets enter the device, the device assigns a set of parameters (including 802.1p precedence, DSCP values, IP precedence, local precedence, and drop precedence) to the packets as configured.
The local precedence and drop precedence are defined as follows:
l A local precedence is locally significant and corresponds to an output queue.
l A drop precedence is used for packet drop. The value 2 corresponds to red packets, the value 1 corresponds to yellow packets, and the value 0 corresponds to green packets.
In interface view, the setting is effective on the current interface only; in port group view, the setting is effective on all the ports in the port group.

Default Level
2: System level
Parameters
queue-id: Output queue ID, in the range of 0 to 7.
group group-id: Specifies a WRR priority group. The group-id argument can be 1 or 2. The WRR priority groups are scheduled by priority.
weight queue-weight: Specifies weight for the queue. The queue-weight argument is in the range 8 to 100.
sp: Specifies the SP queue scheduling algorithm.
Description
Use the qos wrr command to configure the WRR or SP + WRR queue scheduling algorithm for a port or port group.
Use the undo qos wrr command to restore the default.
By default, all the output queues of a port are scheduled using the strict priority (SP) algorithm.
A port on an S5810 switch supports eight output queues. Different queues can adopt different queue scheduling algorithms. As required, you can configure part of the queues on a port to adopt the SP queue scheduling algorithm and part of the queues to adopt the WRR queue scheduling algorithm. The SP+WRR queue scheduling algorithm is implemented by adding queues on a port to SP scheduling queues and WRR queue scheduling queues respectively. For example, queue 0 and queue 1 are in the SP queue scheduling group, and queue 2, queue 3, and queue 4 are in the WRR queue scheduling group 1, queue 5, queue 6, and queue 7 are in WRR queue scheduling group 2. Round robin is performed in WRR group 2 firstly. If no packet is to be sent in WRR group 2, round robin is performed in WRR group 1. At last, packets in the SP queue scheduling group are processed.
When you use the WRR or SP+WRR queue scheduling algorithm, make sure that the queues in the same scheduling group are consecutive.
Examples
# Configure queue 0 and queue 1 on GigabitEthernet1/0/1 to be in SP queue scheduling group. Configure queue 2, queue 3, and queue 4 on GigabitEthernet1/0/1 to be in WRR queue scheduling group 1, with the weight being 20, 70, and 100 respectively. Configure queue 5, queue 6, and queue 7 on GigabitEthernet1/0/1 to be in WRR queue scheduling group 2, with the weight being 10, 50, and 80 respectively.

2: System level
Parameters
cpu: Mirrors traffic to the CPU.
Description
Use the mirror-to cpu command to configure the action of mirroring traffic to the CPU for the traffic behavior.
Use the undo mirror-to cpu command to remove the action.
By default, the action of mirroring traffic to the CPU is not configured for a traffic behavior.
In a traffic behavior, the action of mirroring traffic to an interface and the action of mirroring traffic to the CPU are mutually exclusive. Therefore, you can configure only one of them for a traffic behavior.
Examples
# Configure the action of mirroring traffic to the CPU for the traffic behavior 1.

View

Default Level
3: Manage level
Parameters
ingress: Sets the receive buffer shared by all ports on the switch.
egress: Sets the transmit buffer shared by all ports on the switch.
size-value: Sets the size in blocks of the shared receive buffer or transmit buffer. For the shared receive buffer, the value range is 0 to 2048. For the shared transmit buffer, the value range is 1776 to 7976.
Description
Use the buffer-manage share-size command to set the size in blocks of the receive or transmit buffer shared by all ports on the switch.
Use the undo buffer-manage share-size command to restore the default.
By default, there is no shared receive buffer and the size of the shared transmit buffer is 1776.
The switch supports transmit and receive buffering for ports to eliminate packet loss when traffic is arriving at a rate greater than the physical medium can support or when forwarding decision is made.
With the buffering implementation of the switch, the buffer memory is divided into a shared buffer area and a dedicated buffer area. The shared buffer area is shared by all ports and is user configurable. The remaining buffer memory after the shared buffer area is deducted is the dedicated buffer area, which is assigned evenly among the ports. The dedicated buffer memory of a port cannot be shared by any other ports and is used prior to the shared buffer. A port uses the shared buffer only when its dedicated buffer is inadequate.
You can tune the shared buffer area depending on traffic patterns. If transient large traffic bursts may occur on some ports, you can expand the shared buffer to accommodate the bursts to prevent traffic loss. If transient small traffic bursts often occur on the ports, you can decrease the shared buffer so that each port can get more dedicated buffer memory.
