Viewing Module Information 2-11
The 9H42x-xx Module View
I/F Speed
If you choose the I/F Speed mode, the interface boxes will display the bandwidth
of each individual interface on the 9H42x-xx module: 10M (megabits) for
standard Ethernet; 100M for Fast Ethernet; and 2500M for the INB backplane
interface.
I/F Type
If you choose the I/F Type mode, the interface boxes will display the network
type supported by each interface on the 9H42x-xx module: Eth (ethernet-csmacd)
or Other (for the INB backplane interface). Note that there is no type distinction
between standard Ethernet and Fast Ethernet.
Port Status Color Codes
Three of the Port Status display options — Bridge, Admin, and Operator —
incorporate their own color coding schemes: for the Bridge option, green = FWD,
blue = DIS, magenta = LIS or LRN, orange = BLK, and red = BRK; for Admin and
Operator, green = ON, red = OFF, and blue = N/A (not available).
For all other Port Status selections — Bridge Mapping, Load, Errors, I/F
Mapping, I/F Speed, and I/F Type — color codes will continue to reflect the most
recently-selected mode which incorporates its own color coding scheme.
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 9H42x-xx 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, 9H42x-xx 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 2-3, is a read-only window that displays
the MIBs and the MIB components — and, therefore, the functionality —
supported by the currently monitored device.
