20-134
Function:
After configure this command, the queue bandwidth guarantee is set.
Parameters:
<
queue-id
>
is the queue ID to configure the bandwidth guarantee, the different chip supports the different queue
count, the range is different too, and the ranging from 1 to 8.
<
minimum-bandwidth
>
is the minimum-bandwidth, ranging from 0 to 128000, when input 0, it means the
min-bandwidth function is not take effect.
<
maximum-bandwidth
>
is the maximum-bandwidth, ranging from 0 to 128000, when input 0, it means the
max-bandwidth function is not take effect. The minimum-bandwidth must not bigger than maximum-bandwidth.
Default:
The queue bandwidth have no guarantee.
Command mode:
Port Mode.
Usage Guide:
The minimum-bandwidth guarantee and maximum-bandwidth limit can be configured at the different or same queue.
The queue bandwidth pledge for egress is relative to management mode, for example: one port is the strict
priority-queue, the highest priority is queue 1 now, it will satisfy this queue traffic when block is happened. But if user
want the lower priority of queue having bandwidth, it can remain bandwidth via this command, the lower priority
queue’s minimum-bandwidth will be satisfied at first, then the excess bandwidth is managed according to SP.
Example:
Configure the minimum-bandwidth is 64kbps and the maximum-bandwidth is 128kbps for ethernet1/2 queue1.
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)# mls qos queue 1 bandwidth 64 128
20.13 mls qos trust
Command:
mls qos trust dscp
no mls qos trust dscp
Function:
Configures port trust; the no command disables the current trust status of the port.
