Example
:
The requirement of the configurations is shown as below: to monitor at interface 1/0/1 the
data frames sent out by interface 1/0/9 and received from interface 1/0/7, and the data
frames received by interface 1/0/15 and matched by rule 120(The source IP address is
1.2.3.4 and the destination IP address is 5.6.7.8).
Configuration guidelines:
1. Configure interface 1/0/1 to be a mirror destination interface.
2. Configure the interface 1/0/7 ingress and interface 1/0/9 egress to be mirrored source.
3. Configure access list 120.
4. Configure access 120 to binding interface 15 ingress.
Configuration procedure is as follows:
Switch(config)#monitor session 4 destination interface ethernet 1/0/1
Switch(config)#monitor session 4 source interface ethernet 1/0/7 rx
Switch(config)#monitor session 4 source interface ethernet 1/0/9 tx
Switch(config)#access-list 120 permit tcp 1.2.3.4 0.0.0.255 5.6.7.8 0.0.0.255
