- First 4 octets—First bit = 1, the rest is the IANA enterprise number.
- Fifth octet—Set to 3 to indicate the MAC address that follows.
- Last 6 octets—MAC address of the switch.

What is Cisco SNMP engine ID?
The SNMP engine ID is a unique string used to identify the device for administration purposes. You do not need to specify an engine ID for the device; a default string is generated using Cisco’s enterprise number (1.3. 6.1. 4.1. 9) and the mac address of the first interface on the device.

What is SNMP version 2c?
Community-based Simple Network Management Protocol Version 2 (SNMPv2c) is an experimental Internet protocol defined in RFC 1901, RFC 1905, and RFC 1906. SNMPv2c is the community string- based administrative framework for SNMPv2. Community string is a type of password, which is transmitted in cleartext.
What is the engineid in SNMP?
Every SNMPv3 entity has its own ID, the so called engineID. It is a unique number for every context that a agents operates in. But on most of the devices only one SNMP agent runs, so every device has a unique engineID. The RFC 3411describes in section snmpModules.10(page 40) how the engineIDshould be composed.
What is SNMPv3 (snmpengineid)?
The Simple Network Management Protocol (SNMP) version three (SNMPv3) requires that an application knows the identifier (snmpEngineID) of the remote SNMP protocol engine in order to retrieve or manipulate objects maintained on the remote SNMP entity.
What are SNMPv3 engine ID restrictions?
Similar restrictions require the reconfiguration of community strings when the engine ID changes. A remote engine ID is required when an SNMPv3 inform is configured. The remote engine ID is used to compute the security digest for authenticating and encrypting packets sent to a user on the remote host.
How do I retrieve data from an SNMPv3 agent?
To retrieve data from an SNMPv3 agent, it is necessary to know the appropriate contextEngineID. The User-based Security Model (USM) of SNMPv3 provides a mechanism to discover the snmpEngineID of the remote SNMP engine since this is needed for security processing reasons.
