SNMP Overview
The Simple Network Management Protocol (SNMP) allows you to manage an Athena
node running the SNMP Master agent.
The Master Agent software supports SNMP Version
2.
The SNMP software consists of an SNMP master agent
and numerous SNMP sub-agents .
The Athena implementation of SNMP supports the following
features:
-
MIB II and its SNMP version 2 derivatives (as specified
in RFC 1213 and RFC 1215), including:
-
Statistics counters
-
IP and SNMP management
-
Interface management
-
Interface configuration
-
MIB II SNMP version 1 traps or version 2 notifications
-
Additional Management of Proprietary MIB items
The Athena SNMP implementation fully supports GET
and SET requests.
The Athena SNMP implementation listens on port 161
for SNMP requests and on port 162 for SNMP traps. These are the ports recommended
by RFC 1906.
Master Agent and Sub-Agent Architecture
Athena SNMP support is provided by a run-time extensible SNMP agent.
The extensible SNMP agent is partitioned into a master agent and multiple
sub-agents. This allows:
-
Users to be able to assign new Athena protocol binaries containing additional
sub-agents without re-releasing the master agent or any other Athena/Access
binary.
-
SNMP support for protocol feature additions are accomplished by updating
the protocol sub-agent without re-releasing the master agent.
-
Users can dynamically add/delete protocol tasks at run-time.
-
The SNMP family of agents (master agent and sub-agents) are transparent to
the Network Management Station (i.e. will appear to be a monolithic agent).
SNMP Community and Trap Support
The following items are configurable:
-
SNMP Community Table (read-create)
-
Entry Number (Configure up to four SNMP Communities. Two default
communities of "GUI_Config" and "public" are provided.)
-
Community Name (Configure a Community Name for each entry)
-
Access Level (read-write) (Allow or dis-allow SNMP operations to modify
configuration for the specified community)
-
SNMP Community Address Table (read-create)
-
Community Entry Number
-
Address Entry Number (Configure up to two entries for the above specified
Community)
-
IP Address (Configure an IP address for this entry in the above specified
Community)
-
Trap Level (0-7) (A severity level filter for the above specified entry number).
-
Trap Format (SNMPv1 Trap or SNMPv2 Notification)
-
Trap Status (enable/disable Traps)
