This object specifies a set of transport endpoints which are used in two ways: - to specify the transport endpoints from which an SNMP entity will accept management requests, and - to specify the transport endpoints to which a notification may be sent using the community string matching the corresponding instance of snmpCommunityName. In either case, if the value of this object has zero-length, transport endpoints are not checked when either authenticating messages containing this community string, nor when generating notifications.

The transports identified by this object are specified in the snmpTargetAddrTable. Entries in that table whose snmpTargetAddrTagList contains this tag value are identified.

If a management request containing a community string

that matches the corresponding instance of snmpCommunityName is received on a transport endpoint other than the transport endpoints identified by this object the request is deemed unauthentic.

When a notification is to be sent using an entry in this table, if the destination transport endpoint of the notification does not match one of the transport endpoints selected by this object, the notification is not sent.
