Switch Port Mirroring on the BlackDiamond 10K Switch Only
The traffic filter on the BlackDiamond 10K switch can be defined based on one of the following criteria:
●
Physical port—All data that traverses the port, regardless of VLAN configuration, is copied to the
monitor port.
●
VLAN—All data to and from a particular VLAN, regardless of the physical port configuration, is
copied to the monitor port.
●
Virtual port—All data specific to a VLAN on a specific port is copied to the monitor port.
The monitor port transmits tagged or untagged frames, according to the way you configured the
monitor port. This feature allows you to mirror multiple ports or VLANs to a monitor port, while
preserving the ability of a single protocol analyzer to track and differentiate traffic within a broadcast
domain (VLAN) and across broadcast domains (for example, across VLANs when routing).
NOTE
The monitor port on the BlackDiamond 10K switch must be explicitly configured for tagged or untagged frames
beginning with ExtremeWare XOS version 11.0.
The traffic egressing the monitor port can be either tagged or untagged. If the mirroring is enabled as
tagged on the monitor port, all traffic egressing the monitor port is tagged. In this case, even if some
untagged ports send mirrored traffic to the monitor port, that traffic also egresses the monitor port as
tagged. And, if mirroring is enabled as untagged on the monitor port, all traffic egressing the monitor
port is untagged, including mirrored tagged packets.
When you upgrade to ExtremeWare XOS 11.0 on the BlackDiamond 10K switches, all restored mirroring
configurations are tagged on the monitor ports.
The master port of the load-sharing group can be the monitor port for port-mirroring.
Switch Port-Mirroring Rules and Restrictions for All Switches
This section summarizes the rules and restrictions for configuring switch port mirroring:
●
When you disable mirroring, all the filters are unconfigured.
●
To change monitor ports, you must first remove all the filters.
●
You cannot mirror the monitor port.
●
The mirroring configuration is removed when you:
■
Delete a VLAN (for all VLAN-based filters).
■
Delete a port from a VLAN (for all VLAN-, port-based filters).
■
Unconfigure a slot (for all port-based filters on that slot).
●
Any mirrored port can also be enabled for load sharing (or link aggregation); however, each
individual port of the load-sharing group must be explicitly configured for mirroring.
●
You cannot run sFlow and mirroring on the same port. If you attempt to enable mirroring on a port
that is already enabled for sFlow, the switch returns the following message:
Mirroring is not compatible with SFlow. Mirroring is not enabled!
●
The monitor port is automatically removed from all VLANs; you cannot add it to a VLAN.
