Configuring VLAN Mirroring
– 223 –
â—† 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.
â—† 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.
â—† When mirroring VLAN traffic or packets based on a source MAC address
(see "Configuring MAC Address Mirroring" on page 234), the target port
cannot be set to the same target ports as that used for port mirroring
(see "Configuring Local Port Mirroring" on page 154).
â—† 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.
