Descriptions for each of the fields in this display follow. To change any default value,
enter the line number for item, an equal sign (=), and then the value for the parameter.
Enter to save all configured settings and move onto the next step in the group
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:
. The default setting for all non-Ethernet ports. This mode is appropri-
ate for backbone and hub connections. The port acts as a standard bridge port. It
802.1d
forwards frames out the port. When frames are received, Spanning Tree s are
BPDU BPDU
processed, and Spanning Tree dynamically controls the forwarding state. If flooding
occurs, all frames destined for unknown addresses, broadcast addresses, or multicast
MAC
addresses will be sent to all ports in the same Group. Enter and press to
select Spanning Tree Bridge mode.
. This mode is appropriate for dedicated connections to a single
workstation or server. Spanning Tree is turned off. No Spanning Tree s will be sent
BPDU
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 address has been learned. (An exception to this rule
MAC
occurs on newer Mammoth-generation Ethernet modules, such as the ,
ESM-100C-12 ESM-
, and . When these ports are in optimized mode, packets with unknown
100F-8 ESM-C-32
destination addresses will be flooded.) Packets with a broadcast or multicast destination
will always be allowed. Enter and press to select Optimized Device Switching
mode.
