creation process.
1) Vport
The virtual port number for this port. The next virtual port number available in the switch
is shown by default in this field.
2) Description
Enter a useful description for this virtual port using alphanumeric characters. The descrip-
tion may be up to 30 characters long.
3) Bridge Mode
Select the bridge mode used by this port. The choices are:
Spanning Tree Bridge . The default setting for all non-Ethernet ports. This mode is appropri-
ate for backbone and hub connections. The port acts as a standard 802.1d bridge port. It
forwards BPDU frames out the port. When frames are received, Spanning Tree BPDU s are
processed, and Spanning Tree dynamically controls the forwarding state. If flooding
occurs, all frames destined for unknown
MAC addresses, broadcast addresses, or multicast
addresses will be sent to all ports in the same Group. Enter 3=b and press <Enter> to
select Spanning Tree Bridge mode.
Optimized Device Switching . This mode is appropriate for dedicated connections to a single
workstation or server. Spanning Tree is turned off. No Spanning Tree BPDU s will be sent
and the port will always be in the forwarding state. The port will stay in this mode even if
a Spanning Tree BPDU is detected. In addition, all MACs learned will not be aged out
(regardless of the Bridge Aging Timer setting) until the port is disconnected or configured
to be administratively down. No flooding of packets with an unknown destination address
is allowed after at least one
MAC address has been learned. (An exception to this rule
occurs on newer Mammoth-generation Ethernet modules, such as the ESM-100C-12 , ESM-
100F-8 , and ESM-C-32 . When these ports are in optimized mode, packets with unknown
destination addresses will be flooded.) Packets with a broadcast or multicast destination
will always be allowed. Enter
3=o and press <Enter> to select Optimized Device Switching
mode.
