Authorized Managers; Backup Link; Robust Port Control - HP AdvanceStack 10Base-T Hub-12 Installation And Reference Manual

Installing and Using HP Stack Manager

Authorized Managers

The Authorized Managers window is used to specify the IP or IPX
network addresses of SNMP management stations authorized to manage
this hub and which of the stations should receive SNMP event alarms.

Backup Link

The Backup Link window is used to specify two of the hub's network
ports (AUI, ThinLAN, or twisted-pair) to be used in a backup
(redundant) connection to another hub. It enables you to connect a
second physical link between hubs that will work if the first link fails.
The backup link is used only in the event of primary link failure, thus
eliminating the possibility of loops in the network.
See appendix D, "Backup Links" for more information.

Robust Port Control

The Robust Port Control window allows you to invoke options to
improve the hub's ability to tolerate network problems resulting from
excessive collisions. The configurable options are:
Intelligent Segmentation Recovery
Late Collision Monitoring
These features are described in chapter 3, "Hub Reference", under
"Auto-Segmentation". See the HP Stack Manager online help for
information on how to invoke these features, and when it is appropriate
to do so.
