Commands for Configuring Slots and Ports on a Switch
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

Tagged and untagged traffic is mirrored slightly differently depending on the module that the
mirrored port and the monitor port are on:
■
With a monitor port on a BlackDiamond 8800 original module,
all
traffic egressing the monitor
port is tagged (regardless of what module the ingressing port is on). Even if some untagged ports
send mirrored traffic to the monitor port, that traffic also egresses the monitor port tagged with
the internal VLAN ID.
■
With a monitor port on a BlackDiamond 8800 a-series or e-series module, the mirrored packet is
tagged
only
if the ingress packet is tagged (regardless of what module the ingressing port is on).
If the packet arrived at the ingress port as untagged, the packet egress the monitor port as
untagged.
●
With the BlackDiamond 8800 a-series and e-series modules, you may see a packet mirrored twice.
This occurs only if both the ingress mirrored port and the monitor port are on the same one-half of
the module
and
the egress mirrored port is either on the other one-half of that module or on another
module.
BlackDiamond 10808 and 12804 switch only.
The traffic filter 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 master port of the load-sharing group can be the monitor port for port-mirroring.
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 10808 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 10808 switches, all restored
mirroring configurations are tagged on the monitor ports.
Example
The following example sends all traffic coming into an BlackDiamond 8800 series switch on slot 3, port
2 to the mirror port:
configure mirroring add port 3:2 ingress
