qos default
This command defines the queue, that will be used for packets without any preconfigured rules. The queue with the value of 6 is considered the highest priority.
Syntax
qos default <QUEUE>
Parameters
<QUEUE> – priority queue number, may take values [0 .. 6].
Default value
0
Command mode
CONFIG
Example
qos default 6
Packets for which no other rules are set are queued with priority 6.
qos type
This command allows you to set a rule by which to select the priority field for the package.
The traffic prioritization method will be chosen depending on the configured system rules (IEEE 802.1p/DSCP).
The system distinguishes the following traffic prioritization methods:
- all the priorities are equal;
- packet selection according to IEEE 802.1p;
- packet selection only according to IP ToS (Type of Service) on 3 level - support for Differentiated Services Codepoint (DSCP);
- interaction according to either 802.1p or DSCP/TOS.
Syntax
qos type <TYPE>
Parameters
<TYPE> – traffic prioritization type:
- 0 – all the priorities are equal;
- 1 – package selection only by 802.1p only (Priority field in 802.1Q tag);
- 2 – packet selection only by DSCP/TOS (field Differentiated Services IP packet header, senior 6 bits);
- 3 – interaction either via 802.1p or DSCP/ToS.
Default value
All the priorities are equal.
Command mode
CONFIG
Example
ma4000(config)# qos type 2
Traffic prioritization will be done only via DSCP/TOS.
qos map
This command sets the parameters for the priority queue:
- specifies the value of the field Differentiated Services IP packet header, senior 6 bits;
- value of the Priority field in 802.1Q tag.
Based on the rules set by the qos type command and the specified priority values, packages are selected for this priority queue.
The use of the negative form of the command (no) allows you to remove the entry from the queue settings table.
Syntax
[no] qos map <TYPE> <VALUES> to <QUEUE>
Parameters
<TYPE> – traffic prioritization type:
- 0 – by the 1p standard (used on level 2);
- 1 – by the DSCP/TOS standard (used on level 3).
<VALUES> – value of the field by which the packets are selected is set according to <TYPE> (the values of the fields are entered with a comma or as a range with hyphen ( - )):
- if <TYPE> = 0, then the Priority field value is set to 802.1Q Tag: [0 ... 7];
- if <TYPE> = 1, then set the values of the fields Differentiated Services of the IP packet header, the highest 6 bits. The value is entered in hexadecimal format: [0 .. 63].
<QUEUE> – priority queue number, may take values [0 .. 6].
Command mode
CONFIG
Example
ma4000(config)# qosmap 0 0 to 1
For the 7th priority queue the value of the field priority = 7 in 802.1Q tag.
show qos
This command is used to view the priorities assigned to the queues. The default queue priority is 0. The priority value for the queue is set in the range [0 .. 6], the queue with the priority 6 is considered the most priority.
