IGMP, known as Internet Group Management Protocol, is used to management hosts from
multicast group.
IGMP Proxy:

Disable.
IGMP Snooping:
Allowing switched Ethernet / Wireless to check and make correct
forwarding decisions. Default is set to
Disable.
5.3.9.7 SNMP Access Control
Software on a PC within the LAN is required in order to utilize this function – Simple Network
Management Protocol.
SNMP V1 and V2:
Read Community:
Specify a name to be identified as the Read Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, user obtains this IP address will be able
to view the data.
Write Community:

view and modify the data.
Trap Community:
Specify a name to be identified as the Trap Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, users from this IP address will be sent
SNMP Traps.
SNMP V3:
Specify a name and password for authentication. And define the access right from identified
IP address. Once the authentication has succeeded, users from this IP address will be able
to view and modify the data.
SNMP Version: SNMPV2c and SNMPv3
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the
SNMPv2 security. The "c" comes from the fact that SNMPv2c uses the SNMPv1 community
string paradigm for "security", but is widely accepted as the SNMPv2 standard.
SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote
monitoring.
Traps supported: Cold Start, Authentication Failure.
