What Is RC-IP-UDP-MIB?
RC-IP-UDP-MIB is a Bay Networks/Nortel enterprise MIB for the Accelar/Rapid-City family of routing switches, focused on UDP helper-address and broadcast-forwarding configuration. It exposes configuration-oriented data: a table of named UDP protocols eligible for forwarding and a table of forwarding rules mapping destination ports to destination addresses, along with row-status and table-size counters. Its monitoring value is primarily configuration/software-state verification, confirming that broadcast/UDP helper forwarding such as DHCP or BOOTP relay is correctly provisioned across VLANs, rather than hardware sensor or performance data. It is part of Nortel's Rapid-City private MIB family and is typically used alongside other rc* MIBs covering VLANs and routing on the same platform. It is typically deployed on Nortel/Bay Networks Accelar series Layer 3 switches acting as DHCP/broadcast relay points in campus or enterprise networks, and the RC-IP-UDP-MIB download is available to administrators who want to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in RC-IP-UDP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
What Can Be Monitored
- configured UDP forwarding protocols
- UDP port forward destination address/port
- forwarding table size
- row status of forwarding entries
Supported Devices
- Bay Networks/Nortel Accelar/Rapid-City series routing switch
Monitoring Examples
rcIpUdpProtocolTable/Entry defines named UDP protocols via rcIpUdpProtocolPortNumber and rcIpUdpProtocolName that are eligible for forwarding, while rcIpUdpPortFwdTable/Entry with rcIpUdpPortFwdDestPort and rcIpUdpPortFwdDestAddr configures where broadcasts are actually forwarded. An admin checks rcIpUdpProtocolTableSize and rcIpUdpPortFwdTableSize alongside rcIpUdpPortFwdEntry rowStatus to confirm that helper addresses (e.g., for DHCP relay) are correctly provisioned across VLANs.
