Diffserv Mapping

The switch module supports DiffServ Mapping (Differential Services RFC 2475) for
Ipv4 frames when DiffServ Mapping is enabled on the Setup DiffServ Mapping
window. If the frame is not an Ipv4 frame or DiffServ is not enabled, 802.1p is used.
The size of the switch module DiffServ table is 64 by 4. This specifies the mapping
of 64 DiffServ code points to the four priority queues.
Select Diffserv Mapping on the Class of Service menu and press Enter to access
the following window:
To set up DiffServ Mapping, toggle DiffServ Mapping to Enabled, enter a beginning
and ending Code Point (0 to 63) in the second field, and select the desired Class in
the next field (Low Priority, Med-L Priority, Med-H Priority, and High Priority).
When you are finished, highlight APPLY and press Enter to make your change
effective.

Mirroring

The switch module enables you to copy frames that were transmitted and received
on a source port and to redirect the copies to another target port. The source port
can be one of the four 10/100/1000 Mbps external ports, while the target port is
where you will connect a monitoring/troubleshooting device, such as a sniffer or an
RMON probe and, it must be one of the four 10/100/1000 Mbps external ports.
