SNMP Communities(SNMPv2c only)

This section contains SNMP community settings for SNMPv2c. There is a limit of two SNMP communities. SNMPv2c provides the following two default SNMP communities. You can use these default communities, edit them, or delete them and then add your own.

  • private—includes WRITE-LEVEL access.

From the Actions column, select the following icons to:

  • —Select this icon to edit settings for the adjacent community.

To add a new community, select Add Community, configure the following fields, and then select Save.

This section contains settings for SNMPv3 users.

To add a new SNMP user, select Add User, configure the following user settings, and then select Save:

  • Auth Type—If the security level includes authentication, this field specifies the authentication hash algorithm. The options are: MD5, SHA, SHA224, SHA256, SHA384, and SHA512. In addition, when you add or edit users with authentication, assign the following authentication fields:
    • Auth Password—An authentication password between 8 and 32 characters with alpha, numeric, and special characters.
    • Mask—When checked (the default setting), the Auth Password cannot be read in the GUI. Otherwise, the password is visible.
