each trap to the SNMP manager.
The Trap Community string is only used by SNMP managers using
SNMP version 2c or lower.
Trap

Use this section to configure where to send SNMP traps from the Switch.
Version
Specify the version of the SNMP trap messages.
IP
Enter the IP addresses of up to four managers to send your SNMP traps
to.
Port
Enter the port number upon which the manager listens for SNMP traps.
Username
Enter the username to be sent to the SNMP manager along with the
SNMP v3 trap.
Note: This username must match an existing account on the Switch
(configured in Management > Access Control > Logins
screen).
User

Use this section to configure users for authentication with managers
using SNMP v3.
Note: Use the username and password of the login accounts you
specify in this section to create accounts on the SNMP v3
manager.
Index
This is a read-only number identifying a login account on the Switch.
Username
This field displays the username of a login account on the Switch.
Security
Level
Select whether you want to implement authentication and/or encryption
for SNMP communication from this user. Choose:
• noauth -to use the username as the password string to send to the
SNMP manager. This is equivalent to the Get, Set and Trap
Community in SNMP v2c. This is the lowest security level.
• auth - to implement an authentication algorithm for SNMP messages
sent by this user.
• priv - to implement authentication and encryption for SNMP
messages sent by this user. This is the highest security level.
Note: The settings on the SNMP manager must be set at the same
security level or higher than the security level settings on the
Switch.
Authenticati
on
Select an authentication algorithm. MD5 (Message Digest 5) and SHA
(Secure Hash Algorithm) are hash algorithms used to authenticate
SNMP data. SHA authentication is generally considered stronger than
MD5, but is slower.
