• Advanced Mode—The access rights of a community are defined by a group (defined in the
Groups page). You can configure the group with a specific security model. The access
rights of a group are Read, Write, and Notify.
To define SNMP communities:
1. Click Configuration > System Management>SNMP > Communities.
This page contains a table of configured SNMP communities and their properties.
2. Click Add.
This page enables network managers to define and configure new SNMP communities.
3. Enter the following fields:
• SNMP Management Station—Select User Defined to enter the management
station IP address that can access the SNMP community. Select All to indicate
that any IP device can access the SNMP community.
• IP Version—Select either IPv4 or IPv6.
• IPv6 Address Type—Select the supported IPv6 address type if IPv6 is used. The
options are:
IP Address—Enter the SNMP management station IP address.
•
• Community—Enter the community name used to authenticate the management
station to the device.
• Access Control—Select one of the following:
• Access Mode—Configure the community:
o Link Local—The IPv6 address uniquely identifies hosts on a single network
link. A link local address has a prefix of FE80, is not routable, and can be
used for communication only on the local network. Only one link local
address is supported. If a link local address exists on the interface, this
entry replaces the address in the configuration.
o Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
o Interface—If the IPv6 address type is Link Local, select whether it is
received through a VLAN or ISATAP.
o Basic—In this mode, there is no connection to any group. You can only
choose the community access level (Read Only, Read Write, or SNMP
Admin) and, optionally, further qualify it for a specific view. By default, it
applies to the entire MIB.
o Advanced—In this mode, access is controlled by group configurations.
o Read Only—Management access is restricted to read-only. Changes
cannot be made to the community.
