CONFIGURING VLAN MIRRORING
Use the VLAN > Mirror (Add) page to mirror traffic from one or more
source VLANs to a target port for real-time analysis. You can then attach a
logic analyzer or RMON probe to the target port and study the traffic
crossing the source VLAN(s) in a completely unobtrusive manner.
CLI REFERENCES
◆ "Port Mirroring Commands" on page 1017
COMMAND USAGE
◆ All active ports in a source VLAN are monitored for ingress traffic only.
◆ All VLAN mirror sessions must share the same target port, preferably
one that is not a member of the source VLAN.
◆ When VLAN mirroring and port mirroring are both enabled, they must
use the same target port.
