Fast EtherHub 3500 System User’s Guide

Port Backup Function

The Fast EtherHub 3500 system supports a port backup function (i.e., a redundant link). A hub system can have up to 18 pairs of redundant links. These links are configurable using the in-band or out-of-band management program. When a primary link fails, the secondary (i.e., backup) link automatically takes over.

Notes: 1. To prevent traffic from looping, the primary port is enabled and the backup port disabled. If the system is functioning normally, the Link indicator for the primary port and the Partition indicator for the backup port will be on.

2.It is common practice to attach these links to the same physical device (e.g., two separate adapter cards on a critical server). However, to provide more flexibility, this is not enforced by the configuration program.

Security Features

Intrusion Protection

Any repeater port on the hub can be configured with a preferred source address. If an unauthorized intruder is detected, the network management station can be notified, or a trap can be sent and the port disabled.
