DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
Figure 6-62. Setup Port Mirroring screen
Up to 25 entries can be made to the port mirroring table, but it should be noted that a faster port (a
1000 Mbps Gigabit Ethernet port, for example) should not be mirrored to a slower port (one of the 24
100 Mbps Fast Ethernet port), because many packets will be dropped.
Parameter Description
Action:
<Add/Modify>
This field can be toggled between
Add/Modify and Delete using the
space bar. Entries can be added,
modified or deleted based upon the
port number entered in the Source
Port field.
Source Port [24]
Allows the entry of the port number
of the port to be mirrored. This port
is the source of the packets to be
duplicated and forwarded to the
Target port.
Direction:<Either>
This field can be toggled between
Either, Ingress and Egress. Ingress
mirrors only received packets, while
Egress mirrors only transmitted
packets.

To configure a forwarding priority for a given MAC address, highlight Priority from the main menu and
press Enter.
