DMI
The DMI PCI Hot-Plug service operates in conjunction with the DMI Service Provider
software component. It provides hot-swap/ hot-add functionality for the NIC in Windows
2000 and Windows NT 4.0 hot plug systems. You should consult the system
documentation to determine the supported Hot-Plug capabilities.
The hot-swap feature allows the user to replace a NIC without bringing down the system.
Hot-add functionality allows the user to add a new NIC into the system without bringing
down the system. These capabilities reduce down time, which is critical to many servers
operating in the Windows 2000 and Windows NT 4.0 environment.
To enable this feature, the PC system hardware has to be hot-plug capable and operate on
Windows 2000 and Windows NT 4.0 operating systems. A third party provided DMI 2.0
Service Provider software has to be installed prior to the installation of the 3Com DMI PCI
Hot-Plug service software. This Service Provider software is available from either Intel
Corporation, or Smart Technology Enabler Corporation. The system also requires the Hot
Plug or Hot Swap application software from the system vendor to enable this feature. You
should consult the system documentation to determine the recommended installation
instructions for the DMI software.
The hot-swap and hot-add features are available to the NIC depending on the system
vendor application software. Some vendors may support one or both features depending
on their system hardware and software implementation.
You are limited to add or replace a NIC with a 3Com NIC of
identical
hardware
configuration.
SNMP
The Advanced Server Features sub-agent, baspmgnt.dll, is designed for the Windows
2000 and Windows NT SNMP Service. It is required to install the SNMP service before
installing Advanced Server Features sub-agent.
The Advanced Server Features sub-agent allows an SNMP manager to actively monitor the
configurations and performance of the Advanced Server features. The sub-agent also
provides an alarm trap to an SNMP manager to inform the manager of any changes to the
conditions of the Advanced Server Features component.
The Advanced Server Features sub-agent allows monitoring of the configurations and
statistics for the Advanced Server Features teams, the physical NICs participating in a
team, and the virtual NIC adapters created as the result of teaming. Non-teamed NIC
adapters are not monitored at this time. The Advanced Server Features configuration data
includes information such as team IDs, physical/virtual/VLAN/team adapter IDs, physical/
virtual/VLAN/team/ adapter descriptions, and MAC addresses of the adapters.
The statistics include detailed information such as data packets transmitted and received
for the physical/virtual/VLAN/team NICs.
The alarm trap forwards information about the changes in configuration of the physical
NICs participating in a team, such as physical NIC link up/down, and NIC installed/
removed events.
To monitor this information, an SNMP manager needs to load the BASP MIB database files
to allow monitoring of the information described above. These files shown below, are
included with the enclosed

baspconfig.mib
baspstat.mib
