- _p_e_e_r__e_n_c_a_p_s is a daemon which provides a way to encapsulate proprietary
- SNMP agents, and an integrated environment for hosts that also run an
- off-the-shelf or custom, non-extensible SNMP Agent or proxy.
-
- The _p_e_e_r__s_n_m_p_d(1m) daemon implements the Simple Network Management
- Protocol (SNMP). Since only a single SNMP Agent can be listening to the
- standard SNMP port (UDP port 161), this limits a Manager to access only
- variables associated with one agent. The _p_e_e_r__e_n_c_a_p_s daemon provides a
- mechanism to overcome this problem.
-
- The _p_e_e_r__s_n_m_p_d agent is configured to listen at UDP port 161, so that it
- receives ALL SNMP queries. The other proprietary SNMP Agents are invoked
- listening at alternate ports, not at 161. The _p_e_e_r__e_n_c_a_p_s daemon is
- configured to recognize these SNMP Agents, the alternate port number at
- which they are listening, and the sub-trees (a sub-tree is a set of MIB
- variables subordinate to a node in the naming tree) they are managing.
- When the _p_e_e_r__e_n_c_a_p_s daemon is started up, it reads a configuration file
- containing all this information, and connects to the _e_e_r__s_n_m_p_d
- daemon, informing about these sub-trees.
-
- When the _p_e_e_r__s_n_m_p_d daemon receives a SNMP request corresponding to a
- subtree associated with an encapsulated agent, it passes on them to the
- _p_e_e_r__e_n_c_a_p_s daemon, which converts the requests into SNMPv1 packets, and
- sends the packets to the specific Agent at the specific alternate port.
-
- The reverse is true for the responses and traps.
-
- The _p_e_e_r__s_n_m_p_d and _p_e_e_r__e_n_c_a_p_s daemons use SMUX protocol to communicate
- between each other. Please refer to RFC 1227 for more information on the
- SMUX protocol.
