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.

Guidelines for configuring mirroring on all switches .
This section summarizes the guidelines for
configuring switch port mirroring:
●
When you disable mirroring, all the filters are unconfigured.
●
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.
●
The mirroring filters are not confined to a single module; they can have ports that span multiple
modules.
●
You cannot use the management port at all in switch port-mirroring configurations.
●
You cannot run ELSM and mirroring on the same port. If you attempt to enable mirroring on a port
that is already enabled for ELSM, the switch returns a message similar to the following:
Error: Port mirroring cannot enabled on an ELSM enabled port 1.
Summit X450 family of switches 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. You can specify which traffic the port mirrors:
■
Ingress—Mirrors traffic received at the port.
■
Egress—Mirrors traffic sent from the port.
■
Ingress and egress—Mirrors all traffic forwarded by the port.
(If you omit the optional parameters, all traffic is forwarded; the default for port-based mirroring
is ingress and egress).
●
VLAN—All data to 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.
●
Only 8 VLANs can be mirrored on a given physical port.
●
Only traffic
ingressing
a VLAN can be monitored; you cannot specify ingressing or egressing traffic
when mirroring VLAN traffic.
●
When routing between VLANs, ingress mirrored traffic is presented to the monitor port as
modified
for routing.
●
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 a Summit X450 family of switches in a load-sharing group.
