Monitoring SNMP
3-37
Introduction
This chapter describes how to use Simple Network Management Protocol (SNMP)
information to monitor BSR system management networking activity.
Displaying SNMP Information
SNMP information lets you monitor management activities on the network. For
example, SNMP traps are error messages sent from the SNMP agent to the SNMP
manager to alert system administrators about Cable Modems (CMs) going offline or
online.
Follow the CLI show command to access SNMP Information:
RDN#show snmp
