SmartNode 10k and SNMP
SN10k software SmartMedia supportes basic SNMP implementations in versions 1,2 and 3. Users are allowed to remotely poll (or GET) system variables, known as SNMP Managed Objects, which are defined in files known as MIB modules. In the opposite direction SmartMedia provides messages called SNMP Traps, triggered on some specified system events. Current implementation allows polling based on standard MIBs and proprietary specification (SN-MIB)

SNMP traps
SNMP Trap module implemented in SmartMedia monitors internally the state on some OIDs and triggers suitable notifications in case of a change. Default polling interval for internal polling is set to 1 minute. This value can be modified in the SnmpAgent configuration.

| Trap Name | Details | OID | OBJECTS | RELEASE |

| snNapAvailability |
Network access point availability for calls changed
- For TDM networks (snNapSignalingType=isdn(1), ss7(2),casr2(6)) this means there is a percentage of channels available for calls. ss7 includes sigtran signaling type
- For SIP networks (snNapSignalingType=sip(3)), this means that remote SIP peer started or stopped responding to SIP OPTIONS queries, which effectively results in SIP NAP ability to process calls
- When using H.248 (snNapSignalingType=tdmMedia(5),voipMedia(4)) this means TDM channels or RTP ports availability changed

SNMP SET
Current implementation of SNMP in SmartMedia doesn't support the SNMP SET configuration directive.
SNMP Configuration Tasks
SmartMedia SNMP configuration tasks are oriented on application called SnmpAgent:
