Cabletron Systems 9E312, 9E423 manual Chassis Manager Window

The 9E312/9E423 Module View

LIS (Listening)	(Magenta) The port is not adding information to the
	filtering database. It is monitoring Bridge Protocol Data
	Unit (BPDU) traffic while preparing to move to the
	forwarding state.
BLK (Blocking)	(Orange) The port is on-line, but filtering traffic from
	going across the 9E312/9E423 from one network
	segment to another. Bridge topology information will be
	forwarded by the port.
BRK (Broken)	(Red) The physical interface has malfunctioned.

The Chassis Manager Window

Like most networking devices, Cabletron’s devices draw their functionality from a collection of proprietary MIBs and IETF RFCs. In addition, Cabletron’s newer intelligent devices — like the 9E312/9E423 Module — organize their MIB data into a series of “components.” A MIB component is a logical grouping of MIB data, and each group controls a defined set of objects. For example, 9E312/9E423 Module bridging information is organized into its own component; more generic device and port information resides in the chassis component. Note, too, that there is no one-to-one correspondence between MIBs and MIB components; a single MIB component might contain objects from several different proprietary MIBs and RFCs.

The Chassis Manager window, Figure 2-4, is a read-only window that displays the MIBs and the MIB components — and, therefore, the functionality — supported by the currently monitored device.

The MIBs which provide the 9E312/9E423 Module’s functionality — both proprietary MIBs and IETF RFCs — are listed here

MIB Components are listed here; remember, there’s no one-to-one correspondence between MIBs and MIB Components
