30.3.5 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.
Figure 146 Management > Access Control > SNMP > Trap Group
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.
Authentication 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.
Privacy 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.
Apply 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.
Cancel Click Cancel to begin configuring this screen afresh.
