CODE

qos enable

The command enables QoS on the interface. If a QoS policy is not associated with an interface (the policy binding is described in section service-policy), then the interface operates in Basic QoS mode, otherwise Policy-based QoS.

Basic QoS – traffic classification is performed based on DSCP and/or 802.1p codes depending on the selected trust mode (the command is described in section qos trust). Traffic is sent to the queues in accordance with the DSCP-Queue and/or CoS-Queue tables.

Policy-based QoS — classification and direction of traffic in the queue is based on QoS policies. Each policy defines a set of classes into which traffic should be divided. The ratio of traffic to a specific class of policy is defined at the entrance to the router by ACL rules (the ACL binding is described in section match access-group), for this purpose, a QoS policy is assigned to the incoming direction. To limit the bandwidth of previously classified traffic and other functions, a QoS policy is assigned to the outbound direction.

The use of a negative form (no) of the command disables QoS service on the interface.

Syntax
[no] qos enable

traffic-shape

Set the outgoing traffic rate limiting for a certain queue or interface in total. The command is relevant only for BasicQoS mode of the interface.

The use of a negative form (no) of the command removes the restriction.

Syntax
traffic-shape { <BANDWIDTH> [BURST] | queue <QUEUE> <BANDWIDTH> [BURST] }
no traffic-shape [ queue <QUEUE> ]
Parameters

<QUEUE> – queue identifier, takes values in the range of [1..8];

<BANDWIDTH> – average traffic rate in Kbps, may take values:

  • for gigabitethernet, loopback, e1 interfaces: [1..10000000];
  • for tengigabitethernet interfaces: [3000..100000000];
  • for fortyengigabitethernet interfaces: [3000..40000000];
  • for loopback interfaces:

<BURST> – size of the restrictive threshold in KB, takes the value [4..16000]. It is only possible to specify a value that is a multiple of 4.

Default values:

<BANDWIDTH> – none

<BURST> – 128
