Security can be further enhanced by encrypting the SNMP messages sent from the managers.
Encryption protects the contents of the SNMP messages. When the contents of the SNMP messages are
encrypted, only the intended recipients can read them.

MIBs let administrators collect statistics and monitor status and performance.
The Switch supports the following MIBs:
• SNMP MIB II (RFC 1213)
• RFC 1157 SNMP v1

• RFC 1643 Ethernet MIBs
