SNMP Server
The SNMP server operates on a network device, such as a router, a switch, or a
workstation. It responds to SNMP requests received from SNMP clients and generates
trap messages to alert the client(s) about notable state changes in the network device.
The SNMP server implementation operates over UDP/IP only. It can receive requests
directed to any IP address configured on the router. SNMP requests and responses
are received or sent on UDP port 161. SNMP traps are sent from UDP port 162 by
default or from a configurable port. For traps sent from UDP port 162, you can
configure the destination UDP port for each recipient with the snmp-server host
command.
SNMP MIBs
A MIB specifies the format of managed data for a device function. The goal of a MIB
is to provide a common and consistent management representation for that function
across networking devices.
Your router supports both standard and enterprise SNMP MIBs.
Standard SNMP MIBs
A standard MIB is defined by a body such as the IETF and fosters consistency of
management data representation across many vendors' networking products.
Juniper Networks E Series Enterprise MIBs
An enterprise MIB is defined by a single vendor. In addition to providing consistency
of management data representation across that vendor's product line, the enterprise
MIB also accounts for proprietary functions and value-added features not addressed
by standard MIBs.
For example, boot record extensions to the enterprise MIB enable configuration of
the release (.rel) files for each router, slot, and subsystem. The extensions also enable
booting through the factory defaults, the running configuration, or a configuration
(.cnf) file.
Accessing Supported SNMP MIBs
For complete information about the SNMP MIBs supported by your router, see the
software image bundle that is available for downloading from the Juniper Networks
website. In the MIBs folder you will find information about all supported standard
and Juniper Networks E Series Enterprise (proprietary) MIBs.
