Rem.: A slot number must be assigned to all moduls without automatic slot detection (e.g. all 19 inch components. This has
to carried out by Rackview Configuration. The slot number acts as a reference number for all SNMP accesses.
Of all modules without slot assignment only one will be dis-
played in SNMP with slotnumber 50. All others are not
shown until they get a slotnumber assigned.
All modules without slot assignment are dispayed in SNMP

hmsAlarmEvent Trap is sent with ENTERPRISE OID alarm-

with ENTERPRISE OID scteHmsTree (1.3.6.1.4.1.5591.1).
hmsColdStart Trap is sent to RFC1215 with ENTERPRISE
OID commonIdent (1.3.6.1.4.1.5591.1.3), instead of OID

All messages of type "Notification" are sent as Trap and are
inserted in the SNMP SCTE HMS tables. Since HMS does
not recognize Notifications, “HMS-Severity” minor is re-
ported All messages of type "Notification" are not sent as Trap and
are not inserted in the SNMP SCTE HMS tables.
In the Webbrowser the Notifications are still shown

Trap Verify
If traps are to be transmitted via non permanent links like dial-up links (e.g. using ISDN or standard analog modem), it
is important to verify that the link to the trap receiver is working before any SNMP traps are sent. Otherwise, the traps
could get lost.
With NEC-E software 1.10.x and later, several settings have been introduced to obtain a verification of the link be-
tween the trap transmitter (=NEC) and trap receiver:
• Verify before trap. If enabled, via SNMP Get Request the “sysDescr” OID of the host having the “Trap Verify
Receiver” IP address (see below) is executed before the pending traps are sent. Only after successful reply all
