SNMP Configurations
User Guide    759
Local Engine ID Set the engine ID of the local SNMP agent (the switch) with 10 to 64 hexadecimal 
digits. A valid engine ID must contain an even number of characters. By default, the 
switch generates the engine ID using TP-Link’s enterprise number (80002e5703) 
and its own MAC address.
The local engine ID is a unique alphanumeric string used to identify the SNMP 
engine. As an SNMP agent contains only one SNMP engine, the local engine ID 
can uniquely identify the SNMP agent.
Remote Engine ID Set the engine ID of the remote SNMP manager with 10 to 64 hexadecimal digits. 
A valid engine ID must contain an even number of characters. If no remote SNMP 
manager is needed, you can leave this field empty.
The remote engine ID is a unique alphanumeric string. It is used to identify the 
SNMP engine on the remote device that receives Inform messages from the 
switch.
2)  Click Apply.
Note:
In SNMPv3, changing the value of the SNMP engine ID has important side effects. A user’s password 
is converted to an MD5 or SHA security digest based on the password itself and the engine ID. If the 
value of local engine ID changes, the switch will automatically delete all SNMPv3 local users as their 
security digests become invalid. Similarly, all SNMPv3 remote users will be deleted if the value of 
remote engine ID changes.
2.1.2  Creating an SNMP View
An SNMP view is a subnet of a MIB. NMS manages MIB objects based on the view. The 
system has a default view named viewDefault. You can create a new one or edit the default 
view according to your needs.
