Technical data

Using the Bay Networks Router MIB
303561-A Rev 00
A-11
The line number encodes several attributes of the line it represents. You can use
Technician Interface
list and get commands to examine and decode a line number.
The individual fields of the number correspond to different attributes of a line, as
follows:
0 0000000 00
| | | | | |
resv chan type slot mod conn
Field Purpose
resv
. (0-1) Reserved for future expansion, with a default value of 0.
chan
(0-99) Indexes multiple lines over one connector, such as on the MCT1
board. This is equivalent to “channel” for MIB objects using
“slot.conn.chan” format. For boards that support only 1 line per
connector, chan = 0.
type
(0-99) The interface type identifier (for example: CSMACD and SYNC).
These are the same as the constants defined in the CCT_NAME
portion of the MIB. For example:
CIRCUIT_TYPE_CSMACD (1-10)
CIRCUIT_TYPE_SYNC (2-20)
CIRCUIT_TYPE_T1 (3-30)
CIRCUIT_TYPE_E1 (4-40)
CIRCUIT_TYPE_TOKEN (5-50)
CIRCUIT_TYPE_FDDI (6-60)
CIRCUIT_TYPE_HSSI (7-70)
slot
(1-99) For most Bay Networks routers, each numbered slot holds a CPU
module and a link module. For model ASN routers, this number
represents the chassis unit identifier (which contains a CPU and
drives up to four link modules). You set the ASN slot number by
means of a thumbwheel on the chassis. The thumbwheel has
settings that range from 1 to 4.
mod
(1-9) The module number has a default value of 1 on most Bay Networks
routers, which corresponds to the first (only) module on a slot. The
“mod” can be any number from 1 to 9 for a model ASN router, where
one CPU supports up to four link modules.
conn
(1-16) Connector number for a given media. It is given two digits to
accommodate 16 port boards.
