Figure 6-1 Port Configuration Example
No VLAN has been configured in the switches, default VLAN1 is used.
Switch Port Property
Switch1 1/7 Ingress bandwidth limit: 150 M
Switch2 1/8 Mirror source port
1/9 100Mbps full, mirror source port
1/10 1000Mbps full, mirror destination port
Switch3 1/12 100Mbps full
The configurations are listed below:
Switch1:
Switch1(config)#interface ethernet 1/7
Switch1(Config-If-Ethernet1/7)#bandwidth control 50 both
Switch2:
Switch2(config)#interface ethernet 1/9
Switch2(Config-If-Ethernet1/9)#speed-duplex force100-full
Switch2(Config-If-Ethernet1/9)#exit
Switch2(config)#interface ethernet 1/10
Switch2(Config-If-Ethernet1/10)# speed-duplex force1000-full
Switch2(Config-If-Ethernet1/10)#exit
Switch2(config)#monitor session 1 source interface ethernet1/8;1/9
Switch2(config)#monitor session 1 destination interface ethernet 1/10
Switch3:
Switch3(config)#interface ethernet 1/12
Switch3(Config-If-Ethernet1/12)#speed-duplex force1000-full
Switch3(Config-If-Ethernet1/12)#exit
6.4 Port Troubleshooting
Here are some situations that frequently occurs in port configuration and the advised solutions:
 Two connected fiber interfaces won’t link up if one interface is set to auto-negotiation but the other to
forced speed/duplex. This is determined by IEEE 802.3.
 The following combinations are not recommended: enabling traffic control as well as setting multicast
limiting for the same port; setting broadcast, multicast and unknown destination unicast control as well
as port bandwidth limiting for the same port. If such combinations are set, the port throughput may fall
below the expected performance.
