Hi, I have a problem for police function. Setting the 10m bandwidth police, but one user with one session just can use the below 3m bandwidth. If we don't config the 10m bandwidth police, user with one session can use about 80m bandwidth. Is it TCP procotol limitation or configuration issue? Thank you for patient to overview my problem. Here is the detail information about my test environment and result. Test environment: >>> Notebook1 --------- GE1/0/5(Cisco 3750X) GE1/0/9 ----------- Notebook2 There is a shared folder in Notebook2 We limit the input bandwidth of GE1/0/5 Uploading the file from Notebook1 to Notebook2, and the upload speed is below 3m. Test result: >>> Switch#show int gi1/0/9 | i bit GigabitEthernet1/0/9 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is c08c.60a4.fa09 (bia c08c.60a4.fa09) MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, 30 second input rate 72000 bits/sec, 136 packets/sec 30 second output rate 2660000 bits/sec, 255 packets/sec Switch configuration: >>> mls qos ! policy-map 10m class class-default police 10000000 156250 exceed-action drop ! interface GigabitEthernet1/0/5 switchport access vlan 10 switchport mode access spanning-tree portfast service-policy input 10m ! interface GigabitEthernet1/0/9 switchport access vlan 10 switchport mode access load-interval 30 spanning-tree portfast Thank you.
