AKey Protocols and Interfaces

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 3Com Installation CD:

baspconfig.mib

baspstat.mib

basptrap.mib
