3.7.3.  VLAN-based Mirroring  
In this example, traffic from all ports that are members of VLAN 10 is mirrored to port 0/18. To configure 
VLAN based mirroring: 
1.  Access VLAN Config mode and create VLAN 10
.
 
(QCT) (Config)#vlan database  
(QCT) (Vlan)#vlan 10  
(QCT) (Vlan)#exit 
2.   Configure the destination interface port as port 0/18. 
(QCT) #configure 
(QCT) (Config)#port-monitor session 1 destination interface 0/18 
3.   Configure VLAN 10 as the source interface for the port mirroring session. 
(QCT) (Config)#port-monitor session 1 source vlan 10 
4.   Enable the port mirroring session on the switch. 
(QCT) (Config)#port-monitor session 1 mode 
(QCT) (Config)#exit 
3.7.4.  Flow-based Mirroring  
In this example, traffic from port 1 is mirrored to port 18 if it matches the criteria defined in the IP ACL or 
MAC ACL that are associated with the port mirroring session. 
To configure flow based mirroring: 
1.   Create the extended IP access list IPACL. 
(QCT) #configure 
(QCT) (Config)#ip access-list IPACL 
(QCT) (Config-ipv4-acl)#permit ip 1.1.1.1 0.0.0.0 any 
(QCT) (Config-ipv4-acl)#exit 
2.   Create the mac access list MACL. 
(QCT) #configure 
(QCT) (Config)#mac access-list extended MACL 
(QCT) (Config-mac-access-list)#permit 00:00:00:00:00:11 00:00:00:00:00:00 any
