Hello everyone,

I have a CloudEngine S5731-S24P4X switch running V200R019C10SPC500.

Does this switch model support any sort of bandwidth guarantee for the specific queue? Ie something like QoS queue 6 bandwidth-guarantee percent 1. This will essentially mean in times of congestion this queue will have a bandwidth guarantee of 1 percent of the interface bandwidth.

interface XGigabitEthernet0/0/1

port link-type trunk

port trunk pvid vlan 555

undo port trunk allow-pass vlan 1

port trunk allow-pass vlan 50 555

stp disable

port-isolate enable group 1

qos queue 5 wrr weight 0

qos queue 6 wrr weight 0

qos queue 7 wrr weight 0

trust dscp

Hi WDNJSQ,
The feature you are looking for is bandwidth management.
Bandwidth management technology provides bandwidth guarantee and limiting to improve the bandwidth use efficiency and prevent bandwidth exhaustion. It has 2 functions:
1. Bandwidth guarantee: guarantees the bandwidth required by key services. When a network is busy, the bandwidth for key services is not affected.
2. Bandwidth limiting: limits the bandwidth occupied by non-key services and prevents the non-key services from consuming much bandwidth to affect other services.
The guaranteed Bandwidth per IP address or user group is the minimum bandwidth obtained by packets based on the IP address or user group. The device allocates part of the bandwidth to the traffic of the matching IP address or user group. The specified traffic can use the guaranteed bandwidth exclusively even if the network is busy.
Unfortunately, this feature is only supported on AR100&AR120&AR150&AR160&AR200.
