Cisco 3560 vswitch Port Speed Limit

Cisco 3560 vswitch Port Speed Limit
1. The network indicates that PC1 is connected to Cisco3550 F0/1 at a rate of 1 M. PC1 is connected to Cisco3550 F0/2 at a rate of 2 M. The G0/1 of Cisco3550 is the egress. Ii. Detailed configuration process Note: Each interface supports only one policy in each direction. One policy can be used for multiple interfaces. Therefore, the download speed limit of all PCs should be defined in the same policy (policy-map user-down in this example ), the difference between different PC rates is defined in Class-map. 1. Start QOS Switch (config) # mls qos // start QOS on the Switch 2. Define PC1 (10.10.1.1) and PC2 (10.10.2.1) respectively) access Control list Switch (config) # access-list 10 permit 10.10.1.0 0.0.255 // control pc1 upstream traffic Switch (config) # access-list 100 permit any 10.10.1.0 0.0.255 // control pc1 downstream traffic Switch (config) # access-list 11 permit 10.10.2.0 0.0.0.255 // control pc2 upstream traffic Switch (config) # access-list 111 permit any 10.10.2.0 0.0.0.255 // control pc2 downstream Traffic 3.
