HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)

Configuring an IP address
After you configure HP APA, you must configure an IP address on the interface. To configure an
IP address for a link aggregate or failover group, do the following:
1. Select a link aggregate or failover group in the list pane on the APA main page. The interface
details are displayed in the details pane.
2. Click View/Modify IP Attributes. The View/Modify Attributes page is displayed.
3. Modify the needed IPv4 attributes.
4. Modify the needed IPv6 attributes.
5. Select the Configuration Options you want.
6. Click OK to modify the IP attributes. A message appears informing that the IP attributes are
modified successfully.
The information is updated in the /etc/rc.config.d/netconf (IPv4 logical interface),
/etc/rc.config.d/netconf-ipv6 (IPv6 logical interface), and /etc/hosts (host
aliases information) files.
The APA main page is displayed and the modified network interface IP attributes are displayed
in the list pane.
Configuring the link partner
HP APA also requires that you configure your switches' trunking mode (AUTO ) to match the mode
being used on the server (for example, Cisco Fast EtherChannel (FEC), IEEE 802.3ad Link
Aggregation Control Protocol (LACP) ).
Configuring HP Serviceguard
HP recommends that you configure HP Serviceguard after configuring HP APA. You can then use
the link aggregates or failover groups in your HP Serviceguard configuration. See the HP
Serviceguard documentation for more information.
NOTE: Do not configure HP Serviceguard with ports that are part of a link aggregate or failover
group.
Creating VLANs over APA
To create VLANs over link aggregates or failover groups, complete the following steps:
1. Decide what ports are to be part of the link aggregate or failover group. Then, decide on the
VLANs that will be created over the link aggregate or failover group.
2. Configure the trunks and VLANs on the switch according to the switch’s documentation. If you
want to enable a VLAN on a link aggregate, its trunk on the switch side must be tagged with
the VLAN’s ID.
If you want to enable a VLAN on a failover group, the member ports of the failover group on
the switch side must be tagged with the VLAN’s ID.
3. On the server side, create the link aggregates or failover groups. Then, create the VLANs over
the link aggregate or failover group.
After a link aggregate is in use, you can create, modify, and delete VLANs over it. Users can leave
behind VLANs after the link aggregate or failover group has been cleared. If the link aggregate
or failover group has been cleared, users can neither create VLANs nor modify any VLANs on the
link aggregate or failover group. Users can only delete the VLANs.
See Appendix D (page 92) for examples of configuring VLANs over APA using HP Procurve
switches.
