SNMP MIBs support
Introduction
Management and statistics information is stored in the GbE2 Interconnect Switch in the Management Information Base
(MIB). The GbE2 Interconnect Switch supports several standard MIBs. Values for MIB objects can be retrieved with
any SNMP-based network management software.
In addition to the standard MIBs, the switch also supports its own proprietary enterprise MIB as an extended
Management Information Base. The proprietary MIB is retrieved by specifying the MIB Object-Identifier (OID) at the
network manager station.
MIB values can be either read-only or read/write variables.
• Read-only MIB variables can be constants that are programmed into the switch or variables that change while
the switch is in operation. Examples of read-only constants include the number and types of ports. Examples of
read-only variables are the statistics counters, such as the number of errors that have occurred or how many
kilobytes of data have been received and forwarded through a port.
• Read/write MIB variables are usually related to user-customized configurations. Examples include the IP address
of the switch, Spanning Tree Algorithm parameters, and port status.
SNMP manager software
If you use third-party vendor SNMP software to manage the switch, you can access proprietary enterprise MIBs for the
switch. The MIBs can be found in the utilities on the HP website (http://www.hp.com/support
).
If your software provides functions to browse or modify MIBs, you can also change the MIB values (if the MIB
attributes permit the write operation). This process can be quite involved, because you must use the MIB OIDs,
available in the MIB files, and retrieve them one by one.
Use an SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager, to access
the enterprise-specific MIBs. Compile the MIBs into the MIB database and then use a MIB browser to navigate through
them. For detailed information, access the individual descriptions of each MIB or refer to the documentation that came
with your SNMP manager software.
The GbE2 Interconnect Switch SNMP agent supports SNMP Version 1. Security is provided through SNMP community
strings. The default community strings are “public” for SNMP GET operation and “private” for SNMP SET operation.
Users may specify up to two trap hosts for receiving SNMP traps. The agent will send the SNMP trap to the specified
hosts when appropriate. Traps will not be sent if there is no host specified.
Supported MIBs
The SNMP agent for the GbE2 Interconnect Switch supports the following MIBs:
• bt2Network.mib— Layer 3 configuration information including IP interface, gateway, Domain Name System
(DNS), IGMP, and static Mrouter
• bt2Physical.mib— Layer 2 configuration information including VLAN, trunk groups, spanning tree
configuration, port mirroring, Forwarding Database (FDB) table, MSTP/RSTP, and Uplink Failure Detection
(UFD)
• bt2Switch.mib— General switch configuration information including statistics, system information, port
configuration, RADIUS, Network Time Protocol (NTP), syslog, trap host, Trivial File Transfer Protocol (TFTP),
hardware information, TACACS+, secondary Radius server, and Uplink Failure Detection (UFD)
• bt2trap.mib—GbE2 Interconnect Switch trap information
• hpswitchpl.mib—HP GbE2 Interconnect Switch MIB root definition
• rfc1213.mib—MIB-II for network management of TCP/IP-based internets; Layer 3 IP information/data
• rfc1215.mib—Coldstart, warmstart, linkup trap definitions
• rfc1493.mib—Bridge traps, standard spanning tree, and other Layer 2 switch data
• rfc1573.mib—Defines the IANAifType textual convention, and thus the enumerated values of the ifType
object defined in MIB-II's ifTable
• rfc1757.mib—Remote Network Monitoring (RMON) MIB
• rfc2037.mib—SNMP network management entity MIB for use with multiple STPs
