Local Port Mirroring Commands
– 1019 –
◆ ACL-based mirroring is only used for ingress traffic. To mirror an ACL,
follow these steps:
1. Use the access-list command (page 951) to add an ACL.
2. Use the access-group command to add a mirrored port to access
control list.
3. Use the port monitor access-list command to specify the
destination port to which traffic matching the ACL will be mirrored.
EXAMPLE
The following example configures the switch to mirror all packets from port
6 to 5:
Console(config)#interface ethernet 1/5
Console(config-if)#port monitor ethernet 1/6 both
Console(config-if)#
This example configures port 2 to monitor packets matching the MAC
address 00-12-CF-XX-XX-XX received by port 1:
Console(config)#access-list mac m1
Console(config-mac-acl)#permit 00-12-cf-00-00-00 ff-ff-ff-00-00-00 any
Console(config-mac-acl)#exit
Console(config)#interface ethernet 1/1
Console(config-if)#mac access-group m1 in
Console(config-if)#interface ethernet 1/2
Console(config-if)#port monitor access-list m1
Console(config-if)#
