Configuration notes for VLAN-based mirroring
The following guidelines apply to VLAN-based mirroring configurations:
• A VLAN must have at least one port member configured before monitoring can be configured.
• Multiple VLANs can have monitoring enabled at the same time, and the maximum number of
monitor-configured VLANs is 8.
• FWS devices support one ingress and one egress mirror per system. These mirror ports are
shared by all mirroring features; port-based mirroring, VLAN-based mirroring, ACL-based
mirroring, and MAC-filter-based mirroring.
• The mirror port is subject to the same scheduling and bandwidth management as the other
ports in the system. If the amount of traffic being sent to the mirror port exceeds the available
bandwidth, some of that traffic may be dropped.
• All incoming traffic (tagged and untagged) in the VLAN is mirrored. mirroring is “as-is”, and is
not affected by the configuration of the mirror port itself. Incoming tagged traffic is sent out
tagged and incoming untagged traffic is sent out untagged, regardless of which VLANs the
mirror port belongs to, and whether the mirror port is tagged or untagged.
• VLAN-based mirroring is supported on Layer 2 and Layer 3 images.
