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.
• 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.
VLAN-based mirroring
WIth the new FastIron X Series of modules, the sFlow processing has been separated from the packet
mirroring functionality. This allows for support of VLAN-based mirroring on the FastIron X Series
devices. The packet processor on the FastIron X Series of modules also allows for egress VLAN-
based mirroring. In order for VLAN-based monitoring to function, the FastIron X Series must have only
the following SX modules installed.
The following interface modules are new to the FastIron X Series:
• SX-FI-24GPP
• SX-FI-24HF
