Communities are only defined in SNMPv1 and v2 because SNMPv3 works with
users instead of communities The users belong to groups that have access
rights assigned to them
The Communities page associates communities with access rights, either
directly (Basic mode) or through groups (Advanced mode):
•
Basic mode—The access rights of a community can configure with Read
Only, Read Write, or SNMP Admin In addition, you can restrict the access
to the community to only certain MIB objects by selecting a view (defined
in the SNMP Views page)
•
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:
STEP 1 Click Configuration > System Management > SNMP> Communities
•
This page contains a table of configured SNMP communities and their
properties
STEP 2 Click Add
•
This page enables network managers to define and configure new
SNMP communities
STEP 3 Enter the following fields:
•
SNMP Management Station—Click User Defined to enter the
management station IP address that can access the SNMP community
Click 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:
•
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
•
Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks
•
Interface—If the IPv6 address type is Link Local, select whether it is
received through a VLAN or ISATAP
•
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:
•
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
•
Advanced—In this mode, access is controlled by group configurations
•
Access Mode—Configure the community:
•
Read Only—Management access is restricted to read-only Changes
cannot be made to the community
•
Read Write—Management access is read-write Changes can be made to
the device configuration, but not to the community
•
SNMP Admin—User has access to all device configuration options, as well
as permissions to modify the community SNMP Admin is equivalent to
Read Write for all MIBs except for the SNMP MIBs SNMP Admin is required
for access to the SNMP MIBs
•
View Name—Select an SNMP view (a collection of MIB subtrees to which
access is granted)
•
Group Name—Select an SNMP group that determines the access rights in
Advanced mode
STEP 4 Click Apply The SNMP Community is defined, and the Running
Configuration is updated
Notification Filters
The Notification Filter page enables configuring SNMP notification filters
and Object IDs (OIDs) that are checked After creating a notification filter, it is
possible to attach it to a notification recipient in the Notification Recipients
SNMPv1,2 page, and Notification Recipients SNMPv3 page
The notification filter enables filtering the type of SNMP notifications that are
sent to the management station based on the OID of the notification to be sent
To define a notification filter:
STEP 1 Click Configuration > System Management >SNMP> Notification Filter
