Chapter 35 Access Control Table 111 SNMP Commands COMMAND DESCRIPTION Set Allows the manager to set values for object variables within an agent. Trap Used by the agent to inform the manager of some events. 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. 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 SNMP Traps The Switch sends traps to an SNMP manager when an event occurs. The following tables outline the SNMP traps by category. An OID (Object ID) that begins with "1.3.6.1.4.1.890.1.5.8" is defined in private MIBs. Otherwise, it is a standard MIB OID. The OIDs beginning with "1.3.6.1.4.1.890.1.5.8.55" are specific to the GS2200-24. The OIDs beginning with "1.3.6.1.4.1.890.1.5.8.56" are specific to the GS2200-24P. The OIDs beginning with "1.3.6.1.4.1.890.1.5.8.59" are specific to the GS2200-8. The OIDs beginning with "1.3.6.1.4.1.890.1.5.8.60" are specific to the GS2200-8HP.

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.
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
SNMP Traps
The Switch sends traps to an SNMP manager when an event occurs. The following tables outline the
SNMP traps by category.
An OID (Object ID) that begins with “
1.3.6.1.4.1.890.1.5.8
” is defined in private MIBs. Otherwise,
it is a standard MIB OID.
The OIDs beginning with “
1.3.6.1.4.1.890.1.5.8.
55
” are specific to the GS2200-24. The OIDs
beginning with “
1.3.6.1.4.1.890.1.5.8.
56
” are specific to the GS2200-24P. The OIDs beginning
with “
1.3.6.1.4.1.890.1.5.8.
59
” are specific to the GS2200-8. The OIDs beginning with
1.3.6.1.4.1.890.1.5.8.
60
” are specific to the GS2200-8HP.
Set
Allows the manager to set values for object variables within an agent.
Trap
Used by the agent to inform the manager of some events.
