This is the configuration for SNMP v3.
To access this page, click Sys
tem  SNMP  SNMP V3  User Configuration.
The SNMPv3 Access Mode is a read-only field that shows the access privileges for the user
account. The admin account always has Read/Write access, and all other accounts have
Read Only access.
To configure SNMPv3 settings for the user account:
1. I
n the Authentication Protocol field, specify the SNMPv3 Authentication Protocol setting
for the selected user account. The valid Authentication Protocols are None, MD5, or
SHA. If you select:
• None: The u
ser will be unable to access the SNMP data from an SNMP browser.
• MD5 or SHA:
The user login password will be used as SNMPv3 authentication
password, and you must therefore specify a password. The password must be eight
characters in length.
2. In the Encryption Proto
col field, choose whether to encrypt SNMPv3 packets transmitted by
the switch.
• None. Do not e
ncrypt the contents of SNMPv3 packets transmitted from the switch.
• DES. Encrypt SNMPv3 p
ackets using the DES encryption protocol.
3. If you selecte
d DES in the Encryption Protocol field, enter the SNMPv3 Encryption Key here.
Otherwise, this field is ignored. Valid keys are 0 to 15 characters long.
4. Click App
ly to send the updated configuration to the switch. Configuration changes take
effect immediately.
5. Click Canc
el to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
