Advanced Control Suite for the AT-2931SX Adapter User’s Guide
AT-2931SX Broadcom Advanced Server Program (BASP) Overview
AT-2931SX BASP is an intermediate software driver for Windows Server
2003, Windows 2000, and Linux that provides load-balancing, faulttolerance, and VLAN features. This manual covers BASP for the Windows
2000 and Linux platforms.
The BASP features are provided by creating teams (virtual adapters) that
consist of multiple NIC interfaces. A team can consist of one to eight NIC
interfaces. Each interface can be designated as a primary or standby*
interface. All primary interfaces in a team participate in Load-balancing
operations by sending and receiving a portion of the total traffic. Standby
interfaces take over in the event that all primary interfaces have lost their
links. VLANs can be added to a team to allow multiple VLANs with
different VLAN IDs. A virtual adapter is created for each VLAN added.
Load-balancing and fault-tolerance features work with any third party's
NIC adapters, but will only be supported with the AT-2931SX adapter.
VLANs only work with the AT-2931SX adapters.
Note
*Standby can only be used in Smart Load-Balance mode (see
Limitations below).
Smart Load-balance (SLB) mode works with all Ethernet switches without
configuring the switch ports to any special trunking mode. Only IP traffic
will be load-balanced in both inbound and outbound directions. In
comparison, IPX traffic will be load-balanced in the outbound direction
only. Other protocol packets will be sent and received through one primary
NIC only. Fault-tolerance for non-IP traffic is only supported using AT2931SX adapters. The Generic Trunking mode requires the Ethernet
switch to support some form of port trunking mode (for example, Cisco's
Gigabit EtherChannel or other switch vendor's link aggregation mode).
This mode is protocol-independent and all traffic should be load-balanced
and fault-tolerant.
Note
Allied Telesyn recommends disabling the spanning tree protocol at
the switch when using BASP. This will minimize the downtime due to
spanning tree loop determination when failing over.
Note
The AT-2931SX Broadcom Advanced Server Program (BASP)
requires that at least one adapter in the team must be a AT-2931SX
adapter.

information, network status, and network connectivity. Active Adapters
are listed.
Resources – Shows the system resources of the selected device.
Hardware – Shows the hardware information (the ASIC version and
the firmware version) for the selected device.
Network Test – The Network Test screen allows you to verify IP
network connectivity. This test verifies if the NDIS driver is installed
correctly. Also, it tests connectivity to a gateway or other specified IP
address on the same subnet.
Diagnostics – The Diagnostics screen allows you to view information
about adapters. This function is used to test the network interface
card.
Configuration – Sets configuration options (NIC Battery Saving Mode,
for example).
Statistics – The Statistics screen allows you to view traffic statistics for
both the AT-2931SX adapter as well as adapters from other vendors.
Statistical values and coverage is more comprehensive for the AT2931SX adapter.

The following options are supported under Linux. For additional
information, see Chapter 4, “Installing BACS on a Linux System” on page
47.
Failover and
Load Balance
Virtual LAN
(VLAN)
SLB mode requires NICE drivers and works with all Ethernet switches
without configuring the switch ports to any special trunking mode. Only
IP traffic will be load-balanced in both inbound and outbound
directions.
Generic trunking mode does not require NICE and can work with any
NIC; however, it requires the Ethernet switch to support the technology
and be properly configured. This mode is protocol-independent and all
traffic should be load-balanced and fault-tolerant.
802.3ad mode requires NICE drivers and Ethernet switches
supporting IEEE 802.3ad Link Aggregation. This mode is protocolindependent and all traffic should be load-balanced and fault-tolerant.
All the physical interfaces in the 802.3ad teams are defaulted to be
LACP active. A 802.3ad team requires all the member NICs support
NICE. All the member NICs, once in the 802.3ad team, will be set with
the same MAC address.
VLANs can be added to a team to allow multiple VLANs with different
VLAN IDs. A virtual device is created for each VLAN added.

Control Registers. This test verifies the read and write capabilities of
the network controller registers by writing various values to the
registers and verifying the results. The device driver uses these
registers to perform network functions such as sending and receiving
information. If the test fails, the device may not work properly.
MII Registers. This test verifies the read and write capabilities of the
registers of the physical layer (PHY).
EEPROM. This test verifies the content of the electrically erasable
programmable read-only memory (EEPROM) by reading a portion of
the EEPROM and computing the checksum. The test fails if the
computed checksum is different from the checksum stored in the
EEPROM. An EEPROM image upgrade does not require a code
change for this test.
Internal Memory. This test verifies that the internal memory of the
device is functioning properly. The test writes patterned values to the
memory and reads back the results. The test fails if an erroneous value
is read back. The device cannot function without its internal memory.
On-Chip CPU. This test verifies the operation of the internal CPUs in
the device.
29
Chapter 2: AT-2931SX Broadcom Advanced Control Suite (BACS) Applications
Interrupt. This test verifies that the NDIS driver is able to receive
interrupts from the device.
Loopback MAC. This test verifies that the Network Device Driver
Interface Specification (NDIS) driver is able to send packets to and
receive packets from the device.
Test LE D . This test causes all of the LEDs to blink 5 times for the
purpose of identifying the device.
Statistics On the Statistics Tab, you can view traffic statistics for both Allied Telesyn
network devices and network devices made by other vendors. Statistical
information and coverage are more comprehensive for the AT-2931SX

Chapter 2: AT-2931SX Broadcom Advanced Control Suite (BACS) Applications
Configuring
Teaming
The teaming function allows you to group available network devices
together to function as a team. Teaming is a method of creating a virtual
LAN (a group of multiple devices that function as a single device). The
benefit of this approach is that it enables load balancing and failover.
Teaming is done via BASP. For more information about BASP, see
“Overview” on page 16.
Note
AT-2931SX BASP is available only on computers that use at least
one AT-2931SX Ethernet controller.
An example of this usage is shown in Figure 9. This example shows three
network adapters in the Available Adapters list. When these adapters are
moved to the Load Balance Members list, they function as a single
adapter—that is, each member shares the traffic burden.
34
Figure 9. New Team Configuration Menu
There are 4 types of load balance teams:
Smart Load Balance and Failover. In this type of team, a standby
member handles the traffic if all of the load balance members fail (a
failover event). All load balance members have to fail before the
standby member takes over. When one or more of the load balance
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
members is restored (fallback), the restored team member(s) resumes
the handling the traffic.
Link Aggregation. In this type of team, you can dynamically configure
the network adapters that have been selected to participate in a given
team. If the link partner is not correctly configured for IEEE 802.3ad
link configuration, errors are detected and noted. All adapters in the
team are configured to receive packets for the same MAC address.
The outbound load balancing scheme is determined by the BASP
driver. The team’s link partner determines the load balancing scheme
for inbound packets. In this mode, at least one of the link partners must
be in active mode.
Generic Trunking. This type of team is very similar to the Link
Aggregation type in that all of the adapters in the team need to be
configured to receive packets for the same MAC address. However,
this mode, does not provide Link Aggregation Control Protocol (LACP)
or marker protocol support. This mode supports a variety of
environments where the link partners are statically configured to
support a proprietary trunking mechanism. Generic trunking supports
load balancing and failover for both outbound and inbound traffic.
SLB (Auto-Fallback Disable). This team is identical to Smart Load
Balance and Failover, with the following exception—when the standby
member is active, if a primary member comes back on line, the team
continues using the standby member instead of switching to the
primary member. This type of team is supported only for situations in
which the network cable is disconnected and reconnected to the
network adapter. It is not supported when the adapter is removed or
installed via the Device Manager or a Hot-Plug PCI application.

Note
The maximum number of members in a team is 8.
Note
When team configuration has been correctly performed, a Virtual
Team adapter driver is created for each configured team.
Note
If you disable a virtual team and later want to reenable it, you must
first disable and reenable all team members before you reenable the
virtual team.
Note
When you create Generic Trunking and Link Aggregation teams,
you cannot designate a Standby Member. Standby members work
only with Smart Load Balance and Failover and SLB (Auto-Fallback
Disable) types of teams.
Note
For an SLB (Auto-Fallback Disable) team, when you want to restore
traffic to the load balance members from the standby member, click
the Fallback button on the Team Properties Tab.

procedure.
1. Click the name of the newly created team.
The Team Properties Tab is selected by default.
2. Click the Statistics Tab to view the team statistics.
Adding a VLAN
You also can add VLANs to a team. The concept behind this is that you
are adding multiple virtual adapters that are on different subnets. The
benefit is that your server can have one network adapter that can belong
to multiple subnets. With a VLAN, you can couple the functionality of load
balancing for the Load Balance Members, and you can employ a failover
adapter.
You can define up to 64 VLANs per team (63 tagged and 1 untagged).
VLANs can only be created when all members are AT-2931SX adapters. If
you try to create a VLAN with another type of adapter, an error message
appears.
Note
Disabled AT-2931SX adapters are not recognized and they prevent
the creation of a VLAN. If you attempt to create a VLAN with a
disabled AT-2931SX adapter, an error message appears.
To configure a team with a VLAN, perform the following procedure.
Note
To maintain optimum adapter performance, your system must have
64 MB of system memory for each of the 8 VLANs created per
adapter.
1. Click the name of the team you want to configure.
2. From the Team Properties Tab, click Add VLAN.
3. Type the VLAN ID and VLAN name, then click OK.
The Untagged VLAN check box is exclusively used by the VLAN ID
field. To use VLAN ID 0, simply click this check box. If you type a
VLAN name or ID and the name already exists, an Input Error
message appears.

BASP Driver for Linux
On newer Distributions and Kernels, it may be necessary to remove the
BASP Driver for Linux
BASP is a kernel module designed for 2.4.x kernels that provides loadbalancing, fault-tolerance, and VLAN features. These features are
provided by creating teams that consist of multiple NIC interfaces. A team
can consist of 1 to 8 NIC interfaces and each interface can be designated
as primary or hot-standby (SLB team only). All primary NIC interfaces in a
team participate in Load-balancing operations by sending and receiving a
portion of the total traffic. Hot-standby interfaces take over in the event
that all primary interfaces have lost their links. In addition, VLANs can be
added to a team to allow multiple VLANs with different VLAN IDs. A virtual
device is created for each VLAN added.
There are three BASP modes:
SLB mode. This mode works with all Ethernet switches without
configuring the switch ports to any special trunking mode. BASP
supports Smart Load Balance (SLB™), Generic Trunking and IEEE
802.3ad Link Aggregation. In SLB and 802.3ad modes, all NICE
drivers must support Broadcom NIC Extension (NICE).
Generic trunking mode. This mode does not require NICE and can
work with any NIC; however, it requires the Ethernet switch to support
the technology and be properly configured. This mode is protocolindependent and all traffic should be load-balanced and fault-tolerant.
802.3ad mode. This mode requires NICE drivers and Ethernet
switches supporting IEEE 802.3ad Link Aggregation. This mode is
protocol-independent and all traffic is load-balanced and fault-tolerant.
All the physical interfaces in the 802.3ad teams are defaulted to be
LACP active. A 802.3ad team requires that all of the member NICs
support NICE. All of the member NICs, once in the 802.3ad team, will
be set with the same MAC address.
BASP also provides remote management through the SNMP protocol.
This package is installed separately (see “AT-2931SX BASP SNMP Agent
for Linux” on page 62).
48
Packaging
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
BASP is released in two packaging formats: source RPM and compressed
tar formats. The file names for the two packages are basplnx<version>.src.<arch>.rpm and basplnx-<version>.<arch>.tgz. Identical
source files to build the driver are included in both the RPM and TAR
source packages.

AT-2931SX BASP Configuration for Red Hat and United Linux Distributions
This section describes the AT-2931SX BASP Configuration for Red Hat
and United Linux 1.x based distributions. The AT-2931SX BASP
distribution includes a utility program and several scripts for team
configuration. Most of the steps are only required after the first time
installation. In the following procedure, perform Step 2 "Modify the
configuration script," whenever you change the team configuration.
Since Linux distributions do not automatically load drivers for network
devices unless the device is configured with an IP address, you must
manually configure a network-script file for all of the physical adapters that
will be team members. Network script files are located under /etc/
sysconfig/network-scripts (Red Hat) or /etc/sysconfig/network (United
Linux 1.x). The file name must be prefixed with "ifcfg-" then the physical
adapter alias. For interface eth0, you create a file with the name ifcfg-eth0
and then add the content below.
Note
To avoid failover problems when using AT-2931SX BASP, make
sure that the spanning tree is disabled on the switch which is
connected to the network adapter.
Note
When adding 64 VLANs, the 64th VLAN must have a VLAN ID of 0
(63 VLANs are tagged and 1 VLAN is untagged).
Example:
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
For users of other Linux distributions, follow instructions in the “AT2931SX BASP Configuration and Startup for Other Linux Distributions” on
page 56.
54
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
The AT-2931SX BASP configuration process, perform the following
procedure:
1. Copy a configuration script from the "/etc/basp/samples" directory to
the "/etc/basp" directory.
Note
The configuration script name must be prefixed with "team-".
2. Modify the following parameters of the configuration script:
(a) change the team type
(b) add or delete the physical network interfaces
(c) add or delete the virtual network interfaces
(d) assign IP address to each virtual network interface.
The syntax of the configuration script can be found in “AT-2931SX
BASP Configuration Scripts for Red Hat Distributions” on page 58 or in
the /etc/basp/sample/team-sample script file itself. Note that when
configuring Teaming, at least one Primary Adapter is required.
3. Manually start the team for the first time:
% /etc/init.d/basp start
Note
This step is only required for the first time installation. The team
configuration is started automatically on subsequent reboots.
Note
If not all of the virtual network interfaces are configured with an IP
address, an error message is displayed when starting the AT2931SX BASP team. If this happens, repeat step 2 to configure an
IP address for all of the virtual network interfaces.
Note
Forming multiple teams is possible by copying the sample files into "/
etc/basp/team-<name>" and modifying this file as described in the
sample file.
Note
To create more that one virtual interface (VLAN) for each team, refer
to the respective description section in the sample files.

Broadcom NICE Patches
Also included in this release are network device drivers patched with
Broadcom NICE support. These drivers are originally taken from the Linux
2.4.16 kernel distribution.
To install patched drivers, perform the following procedure.
1. Copy the NICE header file, "nicext.h", to the appropriate Linux kernel
include directory, for example:
% cp /usr/src/nice-2.4.16/nicext.h /usr/src/linux/
include/linux
2. Rename the original network device driver under the Linux kernel
source tree, "/usr/src/linux/drivers/net".
3. Copy the patched drivers to the Linux kernel network driver source
directory, i.e. "/usr/src/linux/drivers/net".
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
4. Follow the kernel rebuild instructions to configure kernel support for
these drivers.
% cd /usr/src/linux
% make config
5. If the patched drivers are configured into the kernel, go to step 7. If the
patched drivers are configured as modules, go to step 6.
6. In the case of supporting only the module version of these drivers, it is
possible to simply run the following to compile patched drivers and to
install them into the proper module directory:
% make modules
% make modules_install
There is no need to compile the complete kernel. Go to step 8.
7. Rebuild the kernel to compile these patched drivers:
% make clean
% make dep
% make
8. Either reboot the system or unload/load the patched modules. Run
configuration scripts to test the patch.

Removal of Physical Interface in Generic Trunking and 802.3ad Mode
In Generic Trunking and 802.3ad mode, all the physical and virtual
interfaces belonging to a team have the same MAC address. This MAC
address is the same address as that of the first physical interface bounded
to the team. If the first physical interface is removed dynamically from the
team using the "baspcfg" tool and bounded to the protocol directly, this
could lead to a duplicate MAC address problem on the network. To
properly remove a physical interface, perform the following procedure.
1. Backup the original team configuration script
% cp /etc/basp/team-gec /etc/basp/backup-gec
Note
"team-gec" is the name of the configuration script.
Note
"backup-gec" is the name of the backup script. The name of the
backup script must NOT be prefixed with "team-".
2. Modify the team configuration script to remove the physical interface.
3. Stop the running team.
% /etc/basp/baspif /etc/basp/backup-gec stop
% /etc/basp/baspteam /etc/basp/backup-gec del
4. Restart the team.
% /etc/basp/baspteam /etc/basp/team-gec add
% /etc/basp/baspif /etc/basp/team-gec start

AT-2931SX BASP SNMP Agent for Linux
This SNMP agent is designed to support the configuration and statistics
information pertaining to the AT-2931SX BASP driver. The AT-2931SX
BASP SNMP agent is available in two packaging formats: TAR archive
and RPM. Both packages include the same script and MIB files.
Installing the
TAR Archive
To uncompress and expand the tar archive, run:
% tar xvfz baspsnmp-{version}.tar
To install AT-2931SX BASP SNMP agent for Linux, perform the following
procedure.
1. Copy the getBaspInfo and genBaspTraps script files into /usr/bin
directory.
2. Copy the BASP-Config-MIB.txt, BASP-Statistics-MIB.txt and BrcmBSAPTrap-MIB.txt into the /usr/share/snmp/mibs directory.
3. Locate the snmpd.conf file.
It is usually located in one of the following directories:
/etc/snmp
/usr/lib/snmp
$HOME/.snmp
4. Add the following lines to the snmpd.conf.
62
pass .1.3.6.1.4.1.4413.1.2.1 /usr/bin/getBaspInfo

AT-2931SX BASP snmp objects such as:
% snmpget localhost public BASP-Config-MIB::btTeamNumber
% snmpgetnext localhost public BASP-ConfigMIB::btTeamNumber
AT-2931SX BASP SNMP objects are provided in the following text
files:
– BASP-Config-MIB.txt
– BASP-Statistics-MIB.txt
– Brcm-BSAPTrap-MIB.txt
Installing the
RPM Package
Complete the following steps to install AT-2931SX BASP SNMP agent
from the RPM package.
1. To install the RPM package, run:
% rpm -i baspsnmp-{version}.i386.rpm
The AT-2931SX BASP script and MIB files are installed. The
snmpd.conf configuration file is modified to add support for the AT2931SX BASP SNMP agent.
2. Follow steps 4 - 6 in the “Installing the TAR Archive” on page 62.

The 802.3ad team member links disconnect and reconnect continuously
when connected to the HP2524 switch. This is a 3rd party issue. It is seen
only when configuring an 802.3ad team with more than 2 members on the
server and connecting to an HP2524 switch, with LACP enabled as
passive or active. The HP switch shows an LACP channel brought up
successfully with only 2 members. All other member's links disconnect
and reconnect. This issue does not occur with a Cisco Catalyst 6500.

Chapter 5: Key Protocols and Interfaces
Adapter Teaming
Teaming provides traffic load balancing and redundant adapter operation
in the event that a network connection fails. When multiple AT-2931SX
adapters are installed in the same server, they can be grouped into teams.
Each team can be configured on the server with up to 8 ports. If traffic is
not identified on any of the adapter team members connections due to
failure of the adapter, cable, switch port, or switch (where the teamed
adapters are attached to separate switches), the load distribution is
reevaluated and reassigned among the remaining team members. In the
event that all of the primary adapters are down, the hot standby adapter
becomes active. Existing sessions are maintained, causing no user
impact.
AT-2931SX BASP supports four schemes of load balancing: Smart Load
Balancing, Link Aggregation (802.3ad), Generic Link Aggregation
(Trunking), and Smart Load Balance Auto-Failback Disable. These
schemes are described in the following sections.
Smart Load
Balancing
(SLB)™
Link Aggregation
(802.3ad)
Generic Link
Aggregation
(Trunking)
The implementation of load balancing is based on IP flow. This feature
supports balancing IP traffic across multiple adapters (that is, team
members) in a bi-directional manner. In this mode, all adapters in the team
have separate MAC addresses. It provides automatic fault detection and
dynamic failover to other team members or to a hot standby member. This
is done independently of the layer 3 protocol (IP, IPX, or Net Beui). It
works with existing layer 2 and 3 switches.
This mode supports Link Aggregation and conforms to the IEEE 802.3ad
(LACP) specification. Configuration software allows you to dynamically
configure which adapters you want to participate in a given team. If there
are 4 adapters in the system, you can select between 2 and 4 adapters to
participate in the team.
If the link partner is not correctly configured for 802.3ad link configuration,
errors are detected and noted. With this mode, all adapters in the team are
configured to receive packets for the same MAC address. The outbound
load-balancing scheme is determined by our BASP driver. The team’s link
partner determines the load-balancing scheme for inbound packets. In this
mode, at least one of the link partners must be in the active mode.
This mode is very similar to 802.3ad in that you need to configure all of the
adapters in the team to receive packets for the same MAC address.
However, generic link aggregation mode does not provide LACP or
marker protocol support. This mode supports a variety of environments
where the NICs’ link partners are statically configured to support a
proprietary trunking mechanism. For instance, this mode could be used to
support Lucent’s "OpenTrunk" or Cisco’s Fast EtherChannel (FEC).
66
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
Basically, generic link aggregation mode is a "light" version of the 802.3ad
link aggregation and is often referred to as 802.3ad static. This approach
is much simpler because there is not a formalized link aggregation control
protocol. As with the other modes, the creation of teams and the allocation
of physical adapters to various teams is done statically via user
configuration software.
Trunking supports load balancing and failover for both the outbound and
inbound traffic.
Smart Load
Balance Auto-
Failback Disable
This team is almost identical to Smart Load Balance and Failover with one
exception. If a primary member comes back on line when the standby
member is active, the team continues using the standby member rather
than switching to the primary member.
67
Chapter 5: Key Protocols and Interfaces
Failover Teaming
Failover Teaming provides a redundant adapter operation in the event that
a network connection fails. When multiple Gigabit Ethernet Adapters are
installed in the same server, they can be paired into teams. Each team
must have at least one adapter, but can support up to eight adapters. The
number of teams is limited by the number of adapters that are installed.
If the primary adapter in a team is disconnected because the adapter,
cable, or switch port fails, the secondary team member becomes active. In
this case, the secondary team member redirects both the inbound and
outbound traffic originally assigned to the primary adapter. Sessions are
maintained; consequently, there is no impact to the user.
Note
Allied Telesyn recommends disabling STP when using the teaming
and fault tolerance features.

VLANs Overview
g
g
g
g
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
VLANs allow you to split your physical LAN into logical subparts, to create
logical segmentation of workgroups, and to enforce security policies
among each logical segment. Each defined VLAN behaves as its own
separate network, with its traffic and broadcasts isolated from the others,
increasing bandwidth efficiency within each logical group. Up to 64 VLANs
(63 tagged and 1 untagged) can be defined for each AT-2931 adapter in
your server, depending on the amount of available memory in your
system.
Although VLANs are commonly used to create individual broadcast
domains and/or separate IP subnets, it is sometimes useful for a server to
have a presence on more than one VLAN simultaneously. The
AT-2931SX adapters support multiple VLANs on a per-port or per-team
basis, allowing very flexible network configurations.

Chapter 5: Key Protocols and Interfaces
Figure 14 on page 69 shows an example network that uses VLANs. In this
example network, the physical LAN consists of a switch, two servers, and
five clients. The LAN is logically organized into three different VLANs,
each representing a different IP subnet. The features of this network are
described in Table 8.
Table 8. Example VLAN Network Topology
Component Description
VLAN #1 An IP subnet consisting of the Main Server, PC #3,
and PC #5. This subnet represents an engineering
group.
VLAN #2 Includes the Main Server, PCs #1 and #2 via shared
media segment, and PC #5. This VLAN is a software
development group.
VLAN #3 Includes the Main Server, the Accounting Server and
PC #4. This VLAN is an accounting group.
Main Server A high-use server that needs to be accessed from all
of the VLANs and IP subnets. The Main Server has an
AT-2931SX adapter installed. All three IP subnets are
accessed via the single physical adapter interface.
The server is attached to one of the switch ports,
which is configured for VLANs #1, #2, and #3. Both
the adapter and the connected switch port have
tagging turned on. Because of the tagging VLAN
capabilities of both devices, the server is able to
communicate on all three IP subnets in this network,
but continues to maintain broadcast separation
between all of them.
Accounting
Server
Available to VLAN #3 only. The Accounting Server is
isolated from all traffic on VLANs #1 and #2. The
switch port connected to the server has tagging
turned off.
PCs #1 and #2Attached to a shared media hub that is then
connected to the switch. PCs #1 and #2 belong to
VLAN #2 only, and are logically in the same IP subnet
as the Main Server and PC #5. The switch port
connected to this segment has tagging turned off.
70
PC #3 A member of VLAN #1, PC #3 can communicate only
with the Main Server and PC #5. Tagging is not
enabled on PC #3’s switch port.
PC #4 A member of VLAN #3, PC #4 can only communicate
with the servers. Tagging is not enabled on PC #4’s
switch port.
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
Table 8. Example VLAN Network Topology (Continued)
Component Description
PC #5 A member of both VLANs #1 and #2, PC #5 has an
AT-2931SX adapter installed. It is connected to switch
port #10. Both the adapter and the switch port are
configured for VLANs #1 and #2 and have tagging
enabled.
Note
VLAN tagging is only required to be enabled on switch ports that
create trunk links to other switches. It is also required on ports
connected to tag-capable end-stations, such as servers or
workstations with AT-2931SX adapters.
VLANs Support Virtual Local Area Networks (VLANs) are commonly used to split up
groups of network users into manageable broadcast domains, to create
logical segmentation of workgroups, and to enforce security policies
among logical segments.
Adaptive
Interrupt
Frequency
Dual DMA
Channels
Each Team supports up to 64 VLANs. Note that only the AT-2931SX
adapters can be part of a team with VLANs. With multiple VLANs on an
adapter, a server with a single adapter can have a logical presence on
multiple IP subnets. With multiple VLANs in a team, a server can have a
logical presence on multiple IP subnets and benefit from load balancing
and failover.
Note
Adapters that are members of a failover team can also be configured
to support VLANs.
Based on traffic conditions, the adapter driver intelligently adjusts host
interrupt frequency to increase overall application throughput. When traffic
is light, the adapter driver interrupts the host for each received packet,
minimizing latency. When traffic is heavy, the adapter issues one host
interrupt for multiple, back-to-back incoming packets, preserving the host
CPU cycles.
The PCI interface on the Gigabit Ethernet Adapter contains two
independent DMA channels for simultaneous read and write operations.
71
Chapter 5: Key Protocols and Interfaces
32-bit or 64-bit
PCI Bus Master
ASIC with
Embedded RISC
Processor
Compliant with PCI Local Bus Rev 2.2, the PCI interface on the Gigabit
Ethernet Adapter is compatible with both 32-bit and 64-bit PCI buses. As a
bus master, the adapter requests access to the PCI bus, instead of waiting
to be polled.
The core control for the Gigabit Ethernet Adapter resides in a tightly
integrated, high-performance ASIC. The ASIC includes dual RISC
processors. This provides the flexibility to add new features to the card
and adapt it to future network requirements via a software download. This
also enables the adapter drivers to exploit the built-in host offload
functions on the adapter as host operating systems are enhanced to take
advantage of these functions.

“AT-2931SX Broadcom Advanced Server Program (BASP)” on
page 78
Windows 2000 This section lists known problems and solutions when using Windows
2000.
Problem: Uninstalling the BASP software and you are prompted to reboot
early.
Solution: After configuring a BASP team, the Windows 2000 system may
sometimes prompt you to reboot. This is because Plug and Play on W2k
may fail to commit any change in the network protocol binding. You can
choose not to reboot and continue configuring the intermediate driver
without causing any side effects. When you have finished the
configuration, you must reboot the system.
Problem: Cannot enable VLAN after it is disabled.
Solution: The BASP application creates additional network connections in
the "Network Connection and Dial-up" Window. Similar to physical
network connections, these virtual connections can be disabled via the
context menu. However, if these virtual connections are re-enabled, the
system reports a "connection failed!" error. This is a known problem with
the Windows 2000 system. When this happens, rebooting the system
reenables the virtual connection.
Problem: Able to configure Internet Connection Sharing (ICS) when there
aren't any unassigned adapters.
Solution: Windows 2000 networking is shipped with the Internet
Connection Sharing (ICS) application, which is designed to allow multiple
computers to access the Internet via a Windows 2000 system. To
configure the ICS application, you need to select a network connection as
an "outside" connection and another network connection as an "inside"
connection. However, the ICS application allows you to select any
available network connection as an "outside" or "inside" connection,
regardless of the BASP team configuration. Allied Telesyn recommends
that you do not select any network connection that is part of the BASP
team to be "outside" or "inside."
76
Advanced Control Suite for the AT-2931SX Adapter User’s Guide
Problem: Team configuration is not retained when you edit it.
Solution: In configuring BASP team configuration, the actual changes of
the configuration are not committed until you click "OK" in the "Network
Properties" window. If you do not click "OK" and, instead, return to the
BASP team configuration window, all the previous uncommitted changes
are lost. This requires you to reenter the configuration. As a workaround,
always click "OK" in the "Network Properties" window after making
changes.
Problem: IP address is configurable on a member of the team.
Solution: When a team is created, the TCP/IP properties for the adapters
are unselected. You can select and configure the TCP/IP properties of the
adapters and configure an IP address manually. This issue is a limitation
of the Windows 2000 network installation paradigm where this invalid
configuration is still allowed.
Problem: When creating 64 VLANs, all virtual adapters are displayed as
disconnected or one of the 64 VLANs is displayed as disabled.
Solution: The maximum VLAN configurations are 63 tagged and one
untagged VLAN ID 0. If 64 tagged VLANs are created, they are
disconnected. A reboot is required and only the 63 tagged VLANs show
links, while the 64th VLAN is disabled.
Linux-BASP This section lists known problems and solutions using Linux-BASP.
Problem: When obtaining the IP for a SLB's virtual interface via DHCP,
the IP-gets lost under heavy traffic.
Solution: Always set a static IP for all the virtual interfaces in a SLB team.
Problem: Make install fails on Turbo Linux 7.0 IA64.
Solution: The symbolic link under /lib/modules/<kernel-version>/build
points to an empty directory. To successfully install BASP using `make
install`, re-link /lib/modules/<kernel-version>/build to point to /usr/src/
<kernel-version>/.

Chapter 7: Manageability Features
CIM
The Common Information Model (CIM) is an industry standard defined by
the Distributed Management Task Force (DMTF). Microsoft implements
CIM on Windows platforms such as Windows 2000 and Windows Server
2003 systems. Allied Telesyn supports CIM on the Windows 2000 and the
Windows Server 2003 platforms.
Allied Telesyn's implementation of CIM provides various classes that
provide information to users through CIM client applications. (Please note
that the AT-2931SX Broadcom CIM data provider provides data only.) You
can choose your preferred CIM client software to browse the information
provided by the AT-2931SX Broadcom CIM provider.
The AT-2931SX Broadcom CIM provider provides information through the
BRCM_NetworkAdapter and BRCM_ExtraCapacityGroup classes.
The BRCM_NetworkAdapter class provides network adapter information
pertaining to a group of adapters including the AT-2931SX adapter and
other vendors' controllers. The BRCM_ExtraCapacityGroup class
provides team configuration for the AT-2931SX BASP feature. Current
implementation provides team information as well as information about
physical network adapters in the team.
AT-2931SX BASP provides events through event logs. You can use the
"Event Viewer" provided by Windows 2000 and Windows Server 2003. Or,
you can use CIM to inspect or monitor these events. AT-2931SX BASP
provider also provides event information through the CIM's generic event
model. These events are __InstanceCreationEvent,
__InstanceDeletionEvent and __InstanceModificationEvent. These events
are defined by CIM. In addition, CIM requires the client application to
register the events from the client application, using queries as examples
(shown below) in order to receive events properly.
SELECT * FROM __InstanceModificationEvent where
TargetInstance ISA "BRCM_NetworkAdapter"
SELECT * FROM __InstanceModificationEvent where
TargetInstance ISA "BRCM_ExtraCapacityGroup"
SELECT * FROM __InstanceCreationEvent where
TargetInstance ISA "BRCM_NetworkAdapter"
SELECT * FROM __InstanceDeletionEvent where
TargetInstance ISA "BRCM_NetworkAdapter"
SELECT * FROM __InstanceCreationEvent where
TargetInstance ISA "BRCM_ActsAsSpare"
SELECT * FROM __InstanceDeletionEvent where
TargetInstance ISA "BRCM_ActsAsSpare"
For detailed information about these events, please refer to the CIM
documentation.

SNMP
There are two SNMP agents for manageability:
BASP Sub-agent
BASP Extensible-agent
See the following sections.
BASP Sub-agent The BASP sub-agent, baspmgnt.dll, is designed for the Windows 2000
and Windows Server 2003 SNMP service. It is required to install the
SNMP service before installing BASP subagent.
The BASP subagent allows the SNMP manager software to actively
monitor the configurations and performance of the AT-2931SX BASP
features. The subagent also provides an alarm trap to an SNMP manager
to inform the manager of any changes to the conditions of the AT-2931SX
BASP component.
The BASP subagent allows monitoring of the configurations and statistics
for the BASP teams, the physical NIC adapters participating in a team, and
the virtual NIC adapters created as the result of teaming. The BASP
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.
Note
Non-teamed NIC adapters are not monitored at this time
The statistics include detailed information such as data packets
transmitted and received for the physical/virtual/VLAN/team adapters.
The alarm trap forwards information about configuration changes to the
physical adapters participating in a team, such as physical adapter link up/
down and adapter installed/removed events.
To monitor this information, an SNMP manager needs to load the
AT-2931SX BASP MIB database files to allow monitoring of the
information described above. These files are shown below:
baspconfig.mib
baspstat.mib
basptrap.mib

AT-2931SX
BASP Extensible-
agent
The AT-2931SX Broadcom SNMP extensible-agent, bcmif.dll, is designed
for the Windows 2000 and Windows Server 2003 SNMP service. The
software requires that a Windows 2000 SNMP service is installed before
installing the extensible-agent.
The extensible-agent allows the SNMP manager software to actively
monitor the configurations of the Interface Card. It is intended to
supplement the information already provided by the standard SNMP
Management Network Interface information.
The extensible-agent provides in-depth information about an AT-2931SX
adapter, such as:
MAC address
bound IP address
IP subnet mask
physical link status
adapter state
line speed
duplex mode
memory range
interrupt setting
bus number
device number
function number
To monitor the information listed above, a SNMP manager needs to load
the MIB file.
The monitored workstation requires the installation of the AT-2931SX
Broadcom SNMP extensible-agent, bcmif.dll, and requires the Microsoft
Windows 2000 or Windows Server 2003 SNMP service to be installed and
loaded.
