Chapter 1 Introduction What is in this Chapter This chapter describes the SPECTRUM Management Module for the Cabletron SNMP Bridge family of devices. It also provides the Model Type Names assigned to the SNMP Bridges in SPECTRUM. The Model Type Name refers to the template used to specify device attributes, actions, and associations for device models in SPECTRUM.
SNMP Bridge Management Module Bdg_CSI_EFDMIM: An EFDMIM Ethernet to FDDI bridging MIM designed for installation in a Cabletron MMAC hub device and managed through SNMP. If you are running a previous version of SPECTRUM, the following user interface aspects may differ from those in SPECTRUM version 4.
Management Module Guide for the Cabletron Systems SNMP Bridges Chapter 2 Device View What is in this Chapter This chapter provides a description of the Device View for the SNMP Bridges Management Module. This description includes an explanation of the menu bar access to the various views used to control and monitor the bridge, and how to use the Device View to view EFDMIMs, access SPECTRUM generic views, and monitor the performance of the bridges.

The LEDs turn on or off to match the bridge on the network. For detailed information on the LED definitions, and the operation of your bridge, refer to the documentation that accompanied your bridge.
SNMP NB30 Device View SNMP NB30 Device View This view represents the physical status of the SNMP NB30 Bridge device and provides menu access to the generic views. These generic views allow you to access network configuration information as well as traffic flow and error data for your bridge. The Device View periodically polls the bridge model in the SpectroSERVER database to determine if any configuration changes have occurred.

The LEDs turn on or off to match the bridge on the network. For detailed information on the LED definitions, and the operation of your bridge, refer to the documentation that accompanied your bridge. The following is a general definition of specific LEDs for the SNMP NB30 bridge model types.
SNMP NB30 Device View SNMP NB30 Front Panel Switches Ethernet Port XMT (Transmit) When this green LED is flashing, the Ethernet side of the bridge is transmitting packets. RCV (Receive) When this yellow LED is flashing, the Ethernet side of the bridge is receiving data packets. CP (Collision Present) When this red LED is flashing, a collision is occurring on that Ethernet segment. POK (Port OK) When this green LED is on, the Ethernet port has passed an Internal Loop Back Test and is ready for transmission.
EFDMIM Device View EFDMIM Device View The EFDMIM is displayed in the Device View for a Cabletron hub. The hub Device View shows an actual representation of the hub with an EFDMIM installed in one of the slots. If the configuration changes (e.g., if an EFDMIM board is pulled or added to the hub), you see the corresponding change within this view. This change in the view occurs after the model’s next poll cycle.

Port Type The IEEE specification of each local port (e.g., 802.3). Port Address The Ethernet address of each local port.
Port Performance View SNMP NB30 Local Port Performance View Table 6-2. Port Topology Settings View Fields Field ! Description Model Name The user-defined name of the bridge model. Bridge Name The name of the NB30. Default is CABLETRON REMOTE BRIDGE. Bridge ID The Ethernet address of the bridge. Network Address The Internet Protocol (IP) address of the SNMP Bridge. Bridge Type The type of bridge (e.g., NB30). Bridge Status The status of the bridge (ON_LINE or STAND BY).
Port Performance View SNMP NB30 Remote Port Performance View SNMP NB30 Remote Port Performance View The NB30 Remote Port Performance View provides the following information: Model Name The user-defined name of the bridge model. Network Address The Internet Protocol (IP) address of the NB30. Port Type The type of remote port, (DSX-1, V35, or Rs449) and the current setting for the Frame Format Switch (ESF or D4).
Port Performance View SNMP NB30 Remote Port Performance View Frames Forwarded This button accesses a rate graph displaying the number of discarded frames over a given time frame. Gauges below the button indicate the number of frames received by the specified port but not discarded during the forwarding process.
Port Performance View SNMP NB30 Remote Port Performance View Two additional buttons are available from the NB30 Remote Port Performance View, as follows: Port Diagnostics The Port Diagnostics button accesses the DSX-1 Loopback Test View. The DSX-1 Loopback Test View provides the following information: Bridge Name The name of the NB30. Default is CABLETRON REMOTE BRIDGE. Network Address The Internet Protocol (IP) address of the NB30. Bridge Status The status of the bridge (ON_LINE or STAND BY).
Port Performance View SNMP NB30 Remote Port Performance View Port Name The name of the NB30 port. The default name is REMOTE PORT. Network Name The name of the network segment connected to the port. Port Type The type of remote port, (DSX-1) and the current setting for the Frame Format Switch (ESF or D4). For more information on setting the Frame Format Switch refer to the NB30 Remote Ethernet Bridge User’s Manual. Bridge Status The status of the bridge (ON_LINE or STAND BY).
Port Performance View SNMP NB30 Remote Port Performance View ! CAUTION Performance Views 6-20 Be certain that both NB30 bridges are configured to use the same channels. When changing the channels used, always change the LOCAL NB30 first, and then change the REMOTE NB30 to correspond to the new configuration for the local device.
Management Module Guide for the Cabletron Systems SNMP Bridges Chapter 7 Event and Alarm Messages What is in this Chapter This chapter describes the events and alarms that Cabletron SNMP Bridge devices generate. Additionally, this appendix notes if an event is mapped to an identical alarm message, and provides any probable cause messages corresponding to these alarms.
NB20E, NB25E, and NB30 Events and Alarms NB20E, NB25E, and NB30 Events and Alarms Table 7-1 provides the events and alarms supported by SPECTRUM for the SNMP NB20E, and SNMP NB25E bridge devices. For a specific list of events that have been generated by a specific hub device, click on a bridge device icon, select New View from the View menu, and select the Performance option.
NB20E, NB25E, and NB30 Events and Alarms Table 7-1. Events and Alarms (Continued) Event Message 0001030b Probable Cause Message 0001030b A(n) {v} device, named {v}, has detected an Lost contact with EGP Neighbor. EGP Neighbor or Loss. EGP Neighbor IP address is {0 1}. 00010401 00010401 Device {v} of type {v} is created with an IP DUPLICATE IP ADDRESS address already used by another model. The model has the same IP address as that of some other Model.
