2 chained EX 4500 I'd like to monitor using SNMP.
http://kb.juniper.net/InfoCenter/index?page=content&id=KB17526
Can anyone please explain how did he translate "jnxOperatingDescr" to "1.3.6.1.4.1.2636.3.1.13.1.5" ?
Thanks!

First, IANA assigns OIDs under 1.3.6.1.4.1 which are "Private Enterprises." Juniper has 1.3.6.1.4.1.2636 (see http://www.alvestrand.no/objectid/1.3.6.1.4.1.html).
To get the rest it is better to trace backwards from the last element "jnxOperatingDescr." Here is the definition:
jnxOperatingDescr OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The name or detailed description of this subject."
::= { jnxOperatingEntry 5 }
The last line indicates the last number in the OID is 5 and the parent is jnxOperatingEntry. Looking at the definition for jnxOperatingEntry and you'll find "::= { jnxOperatingTable 1 }" so the next entry is 1 and the parent is jnxOperatingTable. Tracing these all the way back you get 3.1.13.1.5. Concatentate Juniper's private enterprise 1.3.6.1.4.1.2636.3.1.13.1.5.
