Table 10 describes the significant fields shown in the display.
Table 10 show bridge Field Descriptions
Field
|
Description
|
Total of 300 station blocks
|
Total number of forwarding database elements in the system. The memory to hold bridge entries is allocated in blocks of memory sufficient to hold 300 individual entries. When the number of free entries falls below 25, another block of memory sufficient to hold another 300 entries is allocated. Therefore, the size of the bridge forwarding database is limited to the amount of free memory in the router.
|
295 free
|
Number in the free list of forwarding database elements in the system. The total number of forwarding elements is expanded dynamically, as needed.
|
BG
|
Bridging group to which the address belongs.
|
Hash
|
Hash key/relative position in the keyed list.
|
Address
|
Canonical (Ethernet ordered) MAC address.
|
Action
|
Action to be taken when that address is looked up; choices are to discard or forward the datagram.
|
Interface
|
Interface, if any, on which that address was seen.
|
Age
|
Number of minutes since a frame was received from or sent to that address. The letter "P" indicates a permanent entry. The letter "S" indicates the system as recorded by the router. On the modular systems, this is typically the broadcast address and the router's own hardware address; on the IGS, this field will also include certain multicast addresses.
|
RX count
|
Number of frames received from that address.
|
TX count
|
Number of frames forwarded to that address.

Field

Description
|
Token Ring is up
|
Interface is currently active and inserted into ring (up) or inactive and not inserted (down).
|
Token Ring is Reset
|
Hardware error has occurred. This is not in the sample output; it is informational only.
|
Token Ring is Initializing
|
Hardware is up, in the process of inserting the ring. This is not in the sample output; it is informational only.
|
Token Ring is Administratively Down
|
Hardware has been taken down by an administrator. This is not in the sample output; it is informational only. "Disabled" indicates the Cisco IOS software has received over 5000 errors in a keepalive interval, which is 10 seconds by default.
|
line protocol is up
|
Indicates whether the software processes that handle the line protocol believe the interface is usable (that is, whether keepalives are successful).
|
Hardware
|
Specifies the hardware type. "Hardware is ciscoBus Token Ring" indicates that the board is a CSC-C2CTR board. "Hardware is 16/4 Token Ring" indicates that the board is a CSC-1R, CSC-2R, or a CSC-R16M board. Also shows the address of the interface.
|
Internet address
|
Lists the Internet address followed by the subnet mask.
|
MTU
|
Maximum transmission unit of the interface.
|
BW
|
Bandwidth of the interface in kilobits per second.
|
DLY
|
Delay of the interface in microseconds.
|
rely
|
Reliability of the interface as a fraction of 255 (255/255 is 100 percent reliability), calculated as an exponential average over 5 minutes.
|
load
|
Load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.
|
Encapsulation
|
Encapsulation method assigned to interface.
|
loopback
|
