Configuring a Backup Link

Configure the Monitoring Hub Only.
backup link is performed from the HP Stack Manager program, and you
perform the complete backup link configuration on the "monitoring"
hub. On the "remote" hub, you only need to make sure the ports used in
the primary and backup links are both enabled.
Use the HP Stack Manager's Backup Function.
link, you use the Backup function in the HP Stack Manager. In the
screen, you provide the following information:
the port to be used for the backup link
the port to be used for the primary link
the station address of the hub at the remote end of the link
how frequently (in seconds) test packets (used to check the status of
the primary link) should be sent to the remote hub
how many consecutive response failures will trigger activation of the
backup link
(You can also use the equivalent ASCII console BAckup command.)
Follow this Configuration/Installation Sequence.
installed in a network that includes two connections to another hub, and
the backup link has not yet been configured, a loop in the network exists
causing some network performance degradation. For this reason, it is
better to configure the backup link on the hub before the hub is installed
in the network. It is best to follow these steps:
1. Attach a PC running HP Stack Manager to the hub's RS-232 port, or
to the RS-232 port of any of the hubs in the chain containing the hub
you want to configure, and start HP Stack Manager.
2. Access the hub you want to configure. (Remember that this hub
must have an HP Ethernet SNMP Module installed.)
3. Use the Backup function to configure the backup link. (See the
Backup function description in chapter 2, "Installing and Using HP
Stack Manager", or the software's online help).
