what is the function of mls qos srr-queue input buffers and mls qos srr-queue input bandwidth command? doesn't it do same thing?
The buffer allocation together with the bandwidth allocation control how much data can be buffered and sent before packets are dropped.
when its used with ingress though it can only be set as shared by default when bandwidth is used on egress it can be set as limit shape or share
what is the difference between bandwidth assigned using mls qos srr-queue command and bandwidth assigned using MQC policy-map? does bandwidth assignment for both need to be same?
Layer 2 and layer 3 , srr is for the actual port/interface and its specific queues per hardware based on that port while MQC is for the whole class and everything in it , whether based on access-list or match statements , subnets etc anything that you put under the class and specify the BW statement will be effected by it
The bandwidth command provides a minimum bandwidth guarantee during congestion. There are three forms of the command syntax, as illustrated in this table:
| Command Syntax |

|
