The SNMP management agent supports the following MIBs:
• Read-write for MIB II (RFC 1213), which is an Internet-standard MIB,
consisting of managed objects from the systems, interfaces, IP, ICMP,
TCP, UDP, transmission, and SNMP group
• Read-write for the character-stream devices using SMIv2 MIB (RFC
1658)
• Read-write for the RS-232-like hardware devices MIB (RFC 1659)
• Read-write for the device server IP Network Control Protocol of the
Point-to-Point Protocol MIB (RFC 1473)
The SNMP agent supports the “Set,” “Get,” “GetNext,” and “Trap”
messages as defined in RFC 1157. These messages are used as follows:
• “Set,” which means “set the value of a specific object from one of the
supported MIBs.”
• “Get,” which means “retrieve the value of a specific object form one of
the supported MIBs.”
• “GetNext,” which means “retrieve the value of the next object in the
MIB.”
• “Trap,” which means “send traps to the manager when a particular type
of significant event occurs.”
The SNMP agent can generate and send traps to a destination IP address
when any of the following occur:
• Authentication failures
• Login attempts
• Cold starts (when the Digi device initializes)
• Link up (when a network link comes up)
• For Digi devices connected to a Digi RPM power controller, when the
Digi RPM exceeds the current and temperature thresholds.
set snmp Command
To configure SNMP, use the “set snmp” command. For more information,
see "set snmp" on page 201.
For example, the following “set snmp” command configures SNMP with all
trap options:
#> set snmp run=on trap_dest=190.175.178.73 auth_trap=on
cold_start_trap=on link_up_trap=on curr_thresh_exc_trap=on
temp_thresh_exc_trap=on
