ATM and SNMP

Two of the ATM standards supported by the SunATM software (the User Network Interface (UNI) and LAN Emulation (LANE) specifications) include definitions of SNMP-style Management Information Bases (MIBs) relevant to those standards. These MIBs are referred to as the ATM Forum (ATMF) and LAN Emulation (LANE) MIBs, respectively.

The ATM SNMP daemon (atmsnmpd) handles requests for information in both MIBs, as well as the system MIBs, from SNMP-based network management systems (such as the SunNet Manager program), and from ilmid, when it is required, for SNMP requests coming from the switch.

atmsnmpd can be used as a forwarding agent. If you configure it as a forwarding agent, atmsnmpd will forward SNMP requests for unknown MIBs to the port specified with the forward option, -f. This allows a system to have two SNMP agents respond to requests received over the SNMP port. FIGURE 8-1illustrates the required configuration. To set up this example configuration, atmsnmpd must be started with the parameter -f 1000 and other_snmpd must be started so that it listens on port 1000.
