Below is an example of the progression toward simplification when the identified elements above are added. First, compare the SNMP trap in the raw form below with the one following, which includes the appropriate MIB traps. Next, review the simplified and clearer output when the Cordell ISD 4000 and CiNAS solutions are included.

An SNMP trap in raw form looks like this:

ISD3000 SNMP SNMP Lvl4 VCTAKS02 10:43:53 10:43:552021-06-08 10:43:53 12.182.10.115 [12.182.10.115]:v2
DISMAN-EVENT-MIB:sysUpTimeInstance = Timeticks: (3571907504) 413 days, 9:57:55.04
TrapOID = OID: SNMPv2-SMI:enterprises.14179.2.6.3.53
enterprises.14179.2.6.2.35.0 = [9 v
enterprises.14179.2.6.2.36.0 = 1
enterprises.14179.2.6.2.43.0 = IpAddress: 0.0.0.0
enterprises.14179.2.6.2.39.0 = ""
enterprises.14179.2.6.2.34.0 = [[M
enterprises.14179.2.2.1.1.3.0 = "APf07f.06bf.f91c"
enterprises.14179.2.2.1.1.3.10 = IpAddress: 12.182.10.115

 When you add the appropriate MIB, your trap changes to this:

ISD4000 SNMP SNMP Lvl4 VCTAKS02 09:51:36 09:51:39
2021-06-03 09:51:36 12.182.10.115 [12.182.10.115]:v2
DISMAN-EVENT-MIB:sysUpTimeInstance = Timeticks: (1047458545) 121 days, 5:36:25.45
TrapOID = OID: IF-MIB:linkDown
RFC1213-MIB:ifIndex = 10
RFC1213-MIB:ifAdminStatus = up(1)
RFC1213-MIB:ifOperStatus = down(2)
RFC1213-MIB:ifDescr = "GigabitEthernet 5/17"
RFC1213-MIB:ifType = ethernet-csmacd(6)
CALIX-EPS-MIB:epsMibObjects.3 = "EPS Subscriber Port"
CALIX-SHELF-MIB:resyncActiveAlarms = 8:132
ISDEOM

When you add in the Cordell ISD 4000 and CiNAS solution, we can build rules for the trap and get the following output:

Calix HAYS-A0-C1-S5 EthernetPort#17 Link Down [12.182.10.115]

How do we get to this alarm message?

First, we can tell this is a CALIX SNMP Trap since CALIX is listed in the MIB.

Second, extract the IP in line two “12.182.10.115” and cross-reference this value in our lookup tables to find the EQSSP. HAYS-A0-C1-S5.

Third, we extract the Ethernet Port from line eight “EthernetPort#17”

Fourth, we determine the reason for the alarm in line four linkDown. “Link Down”

Fifth, we add the IP address of the Calix blade for quicker troubleshooting. “[12.182.10.115]”

Why would you want to do this?

By utilizing the SNMP capabilities built into most equipment, you can bring all your alarms from throughout your network into one pane of glass. When you incorporate the ISD 4000 and CiNAS solution you can build clarity and intelligence into your network. Now instead of a standard alarm message, you can identify what happened. where it happened and when it happened in a glance, which speeds response and minimizes downtown.
