Ver. 07-02
Description: You can assign a cost parameter to calculate best path from
each interface to the root bridge. This parameter determines
which bridge interface offers a lower-cost path to the root
bridge. This parameter is valid only for interfaces with
Spanning Tree turned on.
Default:
10
Range of value: 1-65535
Description: You can define the upper 8 bits of port ID (16 bits). Use port ID
to decide which interface should do the Frame Relay when two
ormoreinterfacesonthesamebridgeareconnectedtothe
same network.
Default:
128
Range of value 0-255
Description: You can define whether the transition state of the relevant
interfaceisactiveornot.With
-disable,youcanprohibit
Frame Relay of the specified frame. This parameter is valid
only for interfaces with bridge mode operational (
-spt).
Default:
-enable
Description: You can select the function to translate FDDI frame into the
ether frame format when transmitting to WAN or ATM. This
parameterisvalidonlywhenthespecifiedinterfaceisWANor
ATM. This parameter supports only the bridge, connected with
the specified ether interface. Use it if you cannot recognize
FDDI frame.
The translation of frame format described here is only for MAC
header (regularized with IEEE802.1H), which does not support
partitioning a frame (fragmentation) in the bridge.
-translation_off indicates no translation; -translation indicates
translation.
Default:
-translation_off
