Note: Parallel source routing bridges require unique Bridge ID (hex) values. Non-
parallel bridges do not need unique identifiers.
Circuit Group Name
Identifies the circuit group connecting the bridge and the attached LAN or
network device. Enter the name of the circuit group providing the connection.
Circuit Name
Identifies the circuit (not the circuit group) carrying the traffic specified by
Protocol Type.
Cost
Assigns a relative cost value to the circuit group. Cost is meaningful only if you
have enabled the spanning tree algorithm. Move to the next field to accept the
default value (100) if the spanning tree algorithm is not enabled. Cost reflects the
relative speed of the media—lower costs are for high-speed media and higher
costs are for low-speed media. Use Cost to direct network traffic to higher-speed
media. There are 14 options for Cost:
Default: 100
Options
100 1 40 80
250 10 50 90
500 30 70
65535 30 70
Default
Conversion Type
Assigns the default frame type for conversion. This parameter determines
whether the TRNSB converts frames to 802.3 or the Ethernet V2 format. (This
rule is altered for any stations configured in the Alternate Conversion list).
Configure the frame type used by most (if not all) stations on your
802.3/Ethernet LAN.
Default: 802.3
802.3
Sets the conversion type to 802.3.
Ethernet V2
Sets the conversion type to Ethernet V2.
DL Format
Enables the construction of more complex filters combining MAC-level source
and destination address filtering with protocol-specific filtering.
Default: MAC only
MAC only
Prepares MAC-level source and destination filters. MAC-level source and
destination filters drop or forward a frame based of its source and destination
addresses. MAC-level filters can filter source addresses only, destination
addresses only, or some specified combination of source and destination
addresses. You can construct MAC-level source and/or destination filters for any
of the four supported encapsulation methods—Ethernet, 802.2 LLC, 802.2 SNAP,
or Novell.
