SNMP on the OnBoard
Caution!
The
snmpd
running on OnBoard allows access to proxied data
using the v1 and 2c protocols without the creation of a VPN tunnel, but the
lack of security inherent in these protocols means this option should be used
with caution if it is used at all.
•
The method of access for clients which support version 3 is via a local
Net-SNMP snmp daemon. The proxying of traps is not supported, but
forwarding of traps is supported, with filtering by source address.
If SNMP is used as recommended (by allowing access by hosts running
SNMP clients at version 1 and 2c only through a tunnel), no public client is
allowed unauthenticated access to either managed clients or to the OnBoard
itself. For compatibility with other clients, unencrypted transfer of data is
possible with SNMP v3 connections, but unencrypted data transfer is strongly
discouraged.
Caution!
Because of the risks in unencrypted data transfer, connections
should be encrypted whenever possible.
Views describe the sections of an OID tree that are included and excluded
from access. When a view is being defined, more than one line can be used to
build a view. For example, one line may allow access to a subtree, and another
may remove access to a portion of that subtree.
