the maximum threshold. After a queue depth exceeds the maximum threshold, all other packets that attempt to enter the queue are discarded. In S5148F-ON, flow based coloring is not supported. Consider the following for buffer configuration on S5148F-ON. • Ingress buffer configuration: • Configure the lossy buffer profile on the port and not on priority group, with shared static threshold reaching the maximum switch buffer size. Dynamic threshold mode is not supported. • Configure the lossless LLFC buffer profile on the port and not on priority group, without enabling sharing. The total reserved buffer size is the minimum guaranteed size + headroom size. • Egress buffer configuration: • When ingress is lossy, configure a reserved buffer size for the egress queue. The shared threshold can be either static or dynamic. • When ingress is lossless, configure a static shared threshold with the maximum buffer size. • Configure the reserved buffer size or shared static threshold in multiples of 128. The minimum guaranteed buffer size on a queue is 128. 1 Configure WRED profile in the CONFIGURATION mode. wred wred-profile-name 2 Configure WRED threshold parameters for different colors in the WRED CONFIGURATION mode. random-detect color color-name minimum-threshold threshold-value maximum-threshold thresholdvalue drop probability percent 3 Configure the exponential weight value for the WRED profile in the WRED CONFIGURATION mode. random-detect weight weight-value Configure WRED on a queue and on a port OS10(config)# wred wred_prof_1 OS10(config-wred)# random-detect color yellow minimum-threshold 100 maximum-threshold 300 dropprobability 40 OS10(config-wred)# random-detect weight 4 OS10(config)# class-map type queuing c1 OS10(config-cmap-queuing)# match queue 2 OS10(config-cmap-queuing)# exit OS10(config)# policy-map type queuing p1 OS10(config-pmap-queuing)# class c1 OS10(config-pmap-c-que)# random-detect wred_prof_1 OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# random-detect wred_prof_1 Verify configuration You can view the QoS configuration information related to active class-maps, policy-maps, and match criteria.

discarded.
In S5148F-ON,
flow
based coloring is not supported.
Consider the following for
buffer
configuration
on S5148F-ON.
Ingress
buffer
configuration:
Configure
the lossy
buffer
profile
on the port and not on priority group, with shared static threshold reaching the maximum switch
buffer
size. Dynamic threshold mode is not supported.
Configure
the lossless LLFC
buffer
profile
on the port and not on priority group, without enabling sharing. The total reserved
buffer
size is the minimum guaranteed size + headroom size.
Egress
buffer
configuration:
When ingress is lossy,
configure
a reserved
buffer
size for the egress queue. The shared threshold can be either static or dynamic.
When ingress is lossless,
configure
a static shared threshold with the maximum
buffer
size.
Configure
the reserved
buffer
size or shared static threshold in multiples of 128. The minimum guaranteed
buffer
size on a queue is
128.
