This section shows how to configure the following using SAM: FEC_AUTO mode link aggregates MANUAL mode link aggregates
For information on configuring link aggregates by editing
configuration files, see “Editing Configuration Files for Link Aggregates”. Configuring an FEC_AUTO Mode Link Aggregate | |
When configuring an automatic link aggregate (FEC_AUTO
or LACP_AUTO) using SAM, you configure the link aggregation characteristics
first, followed by the port's modes and characteristics. | | | |  | NOTE: Although this example shows how to configure an
FEC_AUTO mode link aggregate, you can use these steps to configure
an LACP_AUTO link aggregate. Substitute LACP_AUTO for FEC_AUTO, and key for group_capability. | | | | |
Complete the following steps: Log in as superuser. Enter sam at the HP-UX system prompt. Double-click Networking
and Communications, and then Auto Port Aggregation. A window like the one in Figure 3-10 appears. The Networking and Communications screen's List pull-down menu displays one of the following: Link Aggregates supported
by HP APA. This is the list of all available link aggregates in the
system. Network Physical Ports
that Support HP APA. This is the list of all physical ports in the
system that support HP APA.
| | | | | NOTE: The starting PPA number for link aggregates varies
with the operating system installed: for HP-UX 11.0, it is 100; and
for all versions of 11i, it is 900. | | | | |
Click on the link aggregate
to be configured. From the Actions pull-down menu
choose the Configure Link Aggregate option.
A window similar to Figure 3-11 will appear.
Click Advanced
Options to display window similar to Figure 3-12.
Verify the correct settings
for the load-balancing (distribution) algorithm. If required, make
the necessary changes. Change the group capability
of this link aggregate as required. The group capability must be a
nonzero number that differs from the group capability of any other
link aggregate. It must also match the group capability that will
be assigned later to the ports intended to join the link aggregate.
Click OK, then click OK in the Configure Link Aggregate window. Choose the Network
Physical Ports that Support HP APA option from the List pull-down menu. The displayed port configuration mode
(column 7 in Figure 3-13) determines
the mode for the link aggregation. In Figure 3-13 the configuration mode for the ports that support
APA is, by default, set to MANUAL mode. You might need to adjust the
horizontal scroll bar to see all the window's fields. For each port to be configured
in the automatic link aggregation, verify that the port's configuration
mode is set to the desired mode: FEC_AUTO. Check that the port's
group capability matches the group capability that was previously
assigned to the link aggregation. If changes are needed, go to the
next step. Highlight the port to configure
by clicking on the port designated by its PPA. In the Actions pull-down menu, choose the Modify Network Physical
Port Attributes option. You will see a window like the
one in Figure 3-14. In this window, make the necessary
changes and click OK. Repeat steps 8 through 12
to configure the remaining ports to be in the aggregate. Figure 3-15 shows a sample FEC_AUTO
configuration using ports 0 and 1 with a group capability of 7. From the List pull-down menu, choose the Link Aggregates Supported
by HP APA option. A window similar to Figure 3-16 will appear. Note that the
link aggregate might not have a status of UP immediately because HP
APA and the switch or link partner might not have completed the negotiation
required for forming the link aggregation. Wait for the link aggregate
to change status to LINK_UP. Then, configure the IP address on the
link aggregate and continue with the next step. Click once again on the link
aggregate being configured. Then from the Actions pull-down menu, choose the Configure Link Aggregate option. A window like that in Figure 3-17 will appear. Fill in the desired IP address
and subnet mask to be used for the link aggregate. Then click OK. A window like that in Figure 3-18 will appear. Perform one of the following: If the link aggregate has a status of UP the configuration is complete. Exit SAM. Verify that the proper ports
are configured in the proper link aggregation with the lanadmin
-x -v 900 command. If the link aggregate is DOWN If the switch
has not been configured, then exit SAM and configure the switch. The
APA configuration will have been permanently saved and can be modified
later if needed. If the switch has been configured, verify the switch
and HP APA configuration and make the required changes to bring them
into agreement. If the link aggregate still does not form correctly,
see Chapter 6.
SAM permanently saves the HP APA configuration
values in the /etc/rc.config.d/hp_apaconf and /etc/rc.config.d/hp_apaportconf files, which maintains
the values across reboots. Using SAM to Configure a MANUAL Mode Link Aggregate | |
When configuring a manual link aggregate
using SAM, you first configure the port's modes and characteristics,
then configure the link aggregate characteristics. Log in as superuser. Enter sam at the HP-UX system prompt. Double-click Networking
and Communications, and then Auto Port Aggregation. A window like the one in Figure 3-19 appears. The Networking and Communications screen List pull-down menu (Figure 3-19)
displays either of the following: Link Aggregates supported
by HP APA. This is the list of all available link aggregates in the
system. Network Physical Ports
that Support HP APA. This is the list of all physical ports in the
system that support HP APA.
Choose the Network
Physical Ports that Support HP APA option from the List pull-down menu. The port configuration mode (shown
in column 7 in Figure 3-20) determines
the mode for the link aggregate. In Figure 3-20, the configuration mode for the ports that
support HP APA is, by default, set to MANUAL mode. You might need
to adjust the horizontal scroll bar to see all the window's fields. For each port to be configured
in the manual link aggregate, verify that the port's configuration
mode is set to the desired mode: MANUAL. Choose a group capability
number for each port and also for the aggregation. If changes are
needed, go to the next step. Highlight the port to configure
by clicking on the port designated by its PPA. In the Actions pull-down menu, choose the Modify Network Physical
Port Attributes option. A window similar to the one
in Figure 3-21 appears. In this window make the necessary
changes and click OK. Repeat steps 4 through 7 to
configure the remaining ports to be in the aggregate. To configure the link aggregate
characteristics, choose the Link Aggregates supported
by HP APA option from the List pull-down
menu. A window similar to Figure 3-22 appears. Click on the link aggregate
being configured. Then, from the Actions pull-down
menu, choose the Configure Link Aggregate option. A window similar to Figure 3-23 appears. Fill in the desired IP address
and subnet mask to be used for the link aggregate. Click the Advanced
Options button to display a window similar to Figure 3-24.
Verify the correct settings
for the Group Capability (11i v1), assigned in step 4, and either
Hot Standby or the load balancing (distribution) algorithm (not both).
Make the necessary changes, if required. Then click OK. Click Add or Delete
Network Physical Ports. A window similar to Figure 3-25 appears. Highlight a port to be included
in the link aggregate. Then use < to move
it into the link aggregate. Figure 3-26 shows the result of moving lan0 and lan3 into the link aggregate, lan900. Click OK to see the Configure Link Aggregates window (Figure 3-27) with all the link aggregate information filled
in. Clicking OK displays the original window (Figure 3-28). It now shows lan900 configured
as a MANUAL mode link aggregate. The link aggregate is configured.
Configure the next MANUAL mode link aggregate, or exit by choosing
the Exit option from the File pull-down menu.
SAM permanently saves the HP APA configuration
values in the /etc/rc.config.d/hp_apaconf and /etc/rc.config.d/hp_apaportconf files, which maintains
the values across reboots. |
