General SNMP access to the switch

The switch supports SNMP versions 1, 2c, and 3, including SNMP community and trap configuration. The default configuration supports versions 1 and 2c compatibility, which uses plain text and does not provide security options.

Hewlett Packard Enterprise recommends you enable SNMP version 3 for improved security. SNMPv3 includes the ability to configure restricted access and to block all non-version 3 messages (which blocks version 1 and 2c unprotected operation).

SNMPv3 security options include:

  • Configuring device communities as a means for excluding management access by unauthorized stations

  • Configuring for access authentication and privacy

  • Reporting events to the switch CLI and to SNMP trap receivers

  • Restricting non-SNMPv3 agents to either read-only access or no access

  • Coexisting with SNMPv1 and v2c if necessary.
