-- Router interfaces tables.
|
|
|
|
-- A router consists of a number of "boards". Each board may have a
|
|
-- number of "positions", each of which contains a single router
|
|
-- interface. Each boards may also have a number of "slots", which are
|
|
-- places which can take other boards. Thus the physical construction
|
|
-- of a router may be seen as a tree whose nodes are boards and
|
|
-- interfaces, and whose links are positions and slots.
|
|
-- For example, an AR720 with a single Ethernet ICM in Bay 1 has the
|
|
-- following tree:
|
|
-- Bd:AR720 base board
|
|
-- === P1 === Int: Asyn0
|
|
-- === P2 === Int: Asyn1
|
|
-- === P3 === Int: Eth0
|
|
-- === S1 (Bay0) === <empty>
|
|
-- === S2 (Bay1) === Bd:Ethernet ICM === P1 === Int: Eth1
|
|
-- === S3 (MAC) === <empty>
|
|
-- The function of the interface MIB tables is to represent this tree
|
|
-- and to map elements in this tree to other MIB variables. Note that
|
|
-- any given board has a fixed configuration of positions and slots,
|
|
-- it is what is contained in the slots that give different hardware
|
|
-- configurations.
|
|
|
|
-- The highest index of boards in this router. Boards will have indices
|
|
-- from 1 to the value of this object. There may be gaps in the
|
|
-- sequence if the router has hot-swap capability. If the router has no
|
|
-- hot-swap capability, or no swapping has taken place since boot, the
|
|
-- sequence of boards will have no gaps.
