APCD-LM043-8.0 (DRAFT C) 57
CAUTION: By convention, most equipment ships with the
default community strings defined in Table 4. WaveRider
recommends that you change the community strings before you
bring the LMS4000 equipment online, so that outsiders cannot
see information about the internal network or configure system
components.
Management Information Bases (MIBs)
All messages sent between the SNMP server and a network device are based on number
codes. Each of these number codes corresponds to a specific type of information (such as the
quantity of data packets received) associated with a specific type of network device (such as a
CCU). These number codes and their meanings are stored in a management information base
(MIB). The SNMP server and network devices use these MIBs as lookup tables for translating
messages sent between them.
LMS4000 implements SNMPv2c and includes a number of standard and enterprise MIBs:
• RFC1157 (MIB-Il)
• RFC1493 (bridging)
• WaveRider Enterprise MIB (defined in Appendix I on page 251)
You can download WaveRider Enterprise MIBs, which include a comprehensive set of CCU
and EUM parameters and statistics, from the technical support page at www.waverider.com.
