QoS for NI-MLX-1Gx48-T modules
The NI-MLX-1Gx48-T module supports 48 1G port. In a fully loaded 32 slot chassis, there are only 8
queues supported on the TM port. The Brocade chassis supports 1008 ports with 8 queues per
port. Beginning with this release, the Brocade configuration allows you configure more ports in the
system by changing the TM port to use 4 queues instead of 8. The Brocade chassis supports 2016
ports using 4 queues per port.
Limitations on TM ports
The TM Port limitations are reached under the following situations.
1. When a new module type is configured.
2. When a new line card is inserted (no configured type).
3. When the user tries to configure the max-tm-queue parameter from 4 to 8.
The relationship between max TM queues and max TM ports are supported in the system as
follows:
Configuring priority queues from 8 to 4
The system-init max-tm-queues command allows you to configure the maximum number of queues
in TM to 4. To configure priority queues from 8 to 4, enter the following command.
Brocaden(config)# system-init max-tm-queues 4
Syntax: [no] system-init max-tm-queues num
The num value specifies changing the number of queues to 4.
