27.3.5 Configuring SNMP Trap Group

From the SNMP screen, click Trap Group to view the screen as shown. Use the Trap Group
screen to specify the types of SNMP traps that should be sent to each SNMP manager.
210
DESCRIPTION
Enter the port number upon which the manager listens for SNMP traps.
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).
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.
This is a read-only number identifying a login account on the Switch.
This field displays the username of a login account on the Switch.
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.
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.
Specify the encryption method for SNMP communication from this user. You can
choose one of the following:
• DES - Data Encryption Standard is a widely used (but breakable) method of
data encryption. It applies a 56-bit key to each 64-bit block of data.
• AES - Advanced Encryption Standard is another method for data encryption
that also uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
Click Apply to save your changes to the Switch's run-time memory. The Switch
loses these changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory when you
are done configuring.
Click Cancel to begin configuring this screen afresh.
