www.dell.com | support.dell.com Defaults none Command Modes POLICY-MAP-OUT-ETS Command History Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module Usage Information By default, equal bandwidth is assigned to each port queue and each dot1p priority in a priority group. Use the bandwidth-percentage command to configure bandwidth amounts in associated dot1p queues. When specified bandwidth is assigned to some port queues and not to others, the remaining bandwidth (100% minus assigned bandwidth amount) is equally distributed to unassigned non-strict priority queues in the priority group. The sum of the allocated bandwidth to all queues in a priority group should be 100% of the bandwidth on the link. ETS-assigned bandwidth allocation applies only to data queues, not to control queues. The configuration of bandwidth allocation and strict-queue scheduling is not supported at the same time for a priority group. If both are configured, the configured bandwidth allocation will be ignored for priority-group traffic when you apply the output policy on an interface. By default, equal bandwidth is assigned to each priority group in the ETS output policy applied to an egress port if no bandwidth allocation is configured. The sum of configured bandwidth allocation to dot1p priority traffic in all ETS priority groups must be 100%. You must allocate at least 1% of the total bandwidth to each priority group and queue. If bandwidth is assigned to some priority groups but not to others, the remaining bandwidth (100% minus assigned bandwidth amount) is equally distributed to non-strict-priority groups which have no configured scheduler.

Usage

Information

By default, equal bandwidth is assigned to each port queue and each dot1p priority in a priority group.

Use the

bandwidth-percentage

command to configure bandwidth amounts in associated dot1p

queues. When specified bandwidth is assigned to some port queues and not to others, the remaining

bandwidth (100% minus assigned bandwidth amount) is equally distributed to unassigned non-strict

priority queues in the priority group. The sum of the allocated bandwidth to all queues in a priority

group should be 100% of the bandwidth on the link.

ETS-assigned bandwidth allocation applies only to data queues, not to control queues.

The configuration of bandwidth allocation and strict-queue scheduling is not supported at the same

time for a priority group. If both are configured, the configured bandwidth allocation will be ignored

for priority-group traffic when you apply the output policy on an interface.

By default, equal bandwidth is assigned to each priority group in the ETS output policy applied to an

egress port if no bandwidth allocation is configured. The sum of configured bandwidth allocation to

dot1p priority traffic in all ETS priority groups must be 100%. You must allocate at least 1% of the

total bandwidth to each priority group and queue. If bandwidth is assigned to some priority groups but

not to others, the remaining bandwidth (100% minus assigned bandwidth amount) is equally

distributed to non-strict-priority groups which have no configured scheduler.
