Cabletron Systems 9A128-01 manual Chassis Manager Window, Fddi Port Status Color Codes

The 9A128-01 Module View

NOTE

The bridge ports will display Percent Errors when the LER Estimate port status display is selected. Percent Errors are calculated by the following formula: (ErrorPkts /(ErrorPkts+ValidPkts))*100, where Error Pkts = IfInErrors + IfOutErrors + ifInDiscards + ifOutDiscards + ifInUnknownProtos and

ValidPkts = ifInUcastPkts + ifOutUcastPkts + ifInNUcastPkts + ifOutNUcastPkts.

FDDI Port Status Color Codes

FDDI port status color codes always reflect the port’s connection status, even when the LER Estimate port display form has been selected. Under that color coding scheme:

•CON (Connecting) = yellow

•ACT (Active) = green

•SBY (Standby) = red

•DIS (Disabled) = red

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 9A128-01 – 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, 9A128-01 bridging information is organized into its own component; FDDI and ATM information resides in two separate components, one for each of the 9A128-01’s interfaces. 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 2-5, is a read-only window that displays the MIBs and the MIB components — and, therefore, the functionality — supported by the currently monitored device.

To view the Chassis Manager window:

1.Click on Help on the far right of the menu bar at the top of the chassis manager window.

2.Drag down to MIBs Supported, and release.
