IRRORING
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.

◆
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
"Configuring MAC Address Mirroring" on page 237
), the target port
cannot be set to the same target ports as that used for port mirroring
(see
"Configuring Local Port Mirroring" on page 160
).
◆
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.
P
ARAMETERS
These parameters are displayed:
◆
Source VLAN
– A VLAN whose traffic will be monitored.
(Range: 1-4094)
◆
Target Port
– The destination port that receives the mirrored traffic
from the source VLAN. (Range: 1-28/52)
