enable mirroring to port
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

●
When you specify the ingress traffic, the packet is mirrored after it is modified by the ingress process
and may include internal tagging and/or egress tagging.
●
Even if you select ingress and egress traffic, the packet is mirrored only the
first
time it matches a
mirror filter and is not mirrored on subsequent configured filters.
●
You cannot include the monitor port for the BlackDiamond 8800 series switch in a load-sharing
group.
●
You cannot run sFlow and mirroring on the same switch for using the BlackDiamond 8800 original
modules. If you attempt to enable mirroring on these devices 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!
You can run mirroring and sFlow on the same device when you are running one of the following:
■
BlackDiamond a-series and e-series modules
●
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.
NOTE
Beginning with ExtremeWare XOS 11.0, the monitor port must be explicitly configured for tagged or untagged.
Mirroring configurations prior to 11.0 are restored as tagged monitor ports only.
The traffic egressing the monitor port can either be tagged or untagged. If the mirroring is enabled as
tagged on the monitor port of the BlackDiamond 10808 switch, 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 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 11.0, all restored mirroring configurations are tagged monitor ports only.
