The engine ID uniquely identifies an SNMP entity in a network, and it is crucial for the proper functioning of SNMPv3, particularly for authentication and privacy features.

To check engine-id of a VOS node, run following command from shell.
vsh engine-id

Versa follow the standard RFC 3411 to derive Engine-ID, and can be briefly written as below,

8000 <Entrprise-No.> <Format-Type> <Value>

*All values in hexadecimal 

Private Enterprise Number of Versa is 42359 

(Hex Value: A577)

Following number will be assigned against Format-Type field,

IP: 01

MAC-Address:03

Text: 04

Other: 05

Considering the enterprise-number 42359, here is illustration of a different Engine-ID calculation.

set snmp agent engine-id enterprise-number 42359

IP type value: (01)

set snmp agent engine-id from-ip 10.0.0.8              >>> 10.0.0.8 ’s Hex Value 01:00:00:08

Engine-ID: 80:00:a5:77:01:0a:00:00:08

MAC type value: (03)

set snmp agent engine-id from-mac-address 52:54:00:9d:ac:e4                 >>> MAC address is already in Hex format

Engine-ID: 80:00:a5:77:03:52:54:00:9d:ac:e4

Text type value: (04)

set snmp agent engine-id from-text CPE1 >>> Hex value of ASCII text CPE1 - 43:50:45:31
Engine-ID: 80:00:a5:77:04:43:50:45:31

Other type Value: (05)

There is an additional type Other is present.  "type other" typically means that the engine ID does not fit into the predefined categories listed above and may follow a different or proprietary format for SNMP Vendor.
