Configuring VLAN Mirroring
– 162 –
To show the MAC addresses mapped to a VLAN:
1. Click VLAN, MAC-Based.
2. Select Show from the Action list.

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.
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.
◆ When VLAN mirroring and port mirroring are both enabled, the target port can
receive a mirrored packet twice; once from the source mirror port and again
from the source mirrored VLAN.
◆ The target port receives traffic from all monitored source VLANs and can
become congested. Some mirror traffic may therefore be dropped from the
target port.
◆ When mirroring VLAN traffic or packets based on a source MAC address (see
“Configuring MAC Address Mirroring” on page 173), the target port cannot be
set to the same target ports as that used for port mirroring (see “Configuring
Local Port Mirroring” on page 99).
◆ When traffic matches the rules for both port mirroring, and for mirroring of
VLAN traffic or packets based on a MAC address, the matching packets will not
be sent to target port specified for port mirroring.
