Ethernet-based Remote Product Management Revision 8

An MIB file is used for SNMP remote management of a unique device, and consist of a tree of
nodes called Object Identifiers (OIDs). Each OID provides remote management of a particular
function.
Compile these MIB files in a user-supplied MIB Browser or SNMP Network Monitoring System
server.
4.3.2 SNMP Community Strings
In SNMP v1/v2c, the SNMP Community String is sent unencrypted in the SNMP
packets. Caution must be taken by the network administrator to ensure that SNMP
packets travel only over a secure and private network if security is a concern.
The HPOD uses Community Strings as a password scheme that provides authentication before
gaining access to the router agent’s MIBs. They are used to authenticate users and determine
access privileges to the SNMP agent.
Type the SNMP Community String into the user-supplied MIB Browser or Network Node `
Management software.
Three Community Strings are defined for SNMP access:
• Read Community default = public
• Write Community default = private
• Trap Community default = comtech
For proper SNMP operation, the HPOD MIB files must be used with the associated
version of the HPOD M&C. Please refer to the HPOD FW Release Notes for
information on the required FW/SW compatibility.
4.3.3 SNMP Traps
The HPOD sends out SNMP traps both when a fault occurs and when it is cleared.
1) The SNMP agent supports SNMP v1 and v2c.
2) If SNMP v1 traps are to be used, then make sure to compile the traps file.
Use the hpodSNMPTrapVersion OID to configure the type of traps that the HPOD will send.
The HPOD uses these MIB2 v1 traps and v2 notifications:
MIB2 SNMPv1 trap: Authentication Failure 5
MIB2 SNMPv2 notifications: Authentication Failure 1.3.6.1.6.3.1.1.5.5
