Chapter 27 Access Control 27.3.1 SNMP v3 and Security SNMP v3 enhances security for SNMP management. SNMP managers can be required to authenticate with agents before conducting SNMP management sessions. 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. 27.3.2 Supported MIBs 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 1493 Bridge MIBs • RFC 1643 Ethernet MIBs • RFC 1155 SMI • RFC 2674 SNMPv2, SNMPv2c • RFC 1757 RMON • SNMPv2, SNMPv2c or later version, compliant with RFC 2011 SNMPv2 MIB for IP, RFC 2012 SNMPv2 MIB for TCP, RFC 2013 SNMPv2 MIB for UDP 27.3.3 SNMP Traps The Switch sends traps to an SNMP manager when an event occurs. This table lists the beginnings of the private MIB trap OIDs for the various ES-2108 models. An OID (Object ID) that begins with one of the numbers listed here is defined in the related model's private MIBs. Otherwise, it is a standard MIB OID.

SNMP v3 and Security
SNMP v3 enhances security for SNMP management. SNMP managers can be required to
authenticate with agents before conducting SNMP management sessions.
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.
27.3.2
Supported MIBs
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 1493 Bridge MIBs
RFC 1643 Ethernet MIBs
RFC 1155 SMI
RFC 2674 SNMPv2, SNMPv2c
RFC 1757 RMON
SNMPv2, SNMPv2c or later version, compliant with RFC 2011 SNMPv2 MIB for IP,
RFC 2012 SNMPv2 MIB for TCP, RFC 2013 SNMPv2 MIB for UDP
27.3.3
SNMP Traps
The Switch sends traps to an SNMP manager when an event occurs.
This table lists the beginnings of the private MIB trap OIDs for the various ES-2108 models.
An OID (Object ID) that begins with one of the numbers listed here is defined in the related
model’s private MIBs. Otherwise, it is a standard MIB OID.
The following tables outline the SNMP traps by category. For private MIBs, the listed Object
ID shows an “X” for the numbers that vary by model. Refer to
Table 78 on page 205
for the
numbers that go with each model.
