no monitor session <session> source

{interface <interface-list>}

Specifies mirror source port; the no

command deletes mirror source port.

3. Specify flow mirror source

Mirror Examples

1． 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

Switch(config)#monitor session 4 source interface ethernet 1/0/15 access-list 120 rx
