Redundant Link Capacity

Redundant links can be configured enabling up to 24 pairs in a hub. For each pair of redundant links one port must be set as the primary and active, the other as backup and isolated. If the primary port fails, it is isolated and the backup port is set to primary and active.

Address Tracking Capability

The 10/100 Managed Hub provides MAC Address based tracking capability for traffic analysis to diagnose network problems such as Intrusion. This function records the source MAC address of each data packet received by the port and provides the filter for data analysis. Up to 15 source MAC addresses can be detected on each port.

Source Address Search Capability

The 10/100 Managed Hub provides Source Address Search Capability. This active address tracking capability is used to watch for a given MAC address and report on which port it was seen. This capability can be used to collect the necessary information for mapping the topology of a network. Up to 8 MAC addresses can be searched simultaneously. You can configure address search parameters including Source MAC address and Address Search Status with local console management, Web-Based Management or SNMP management.

Security Intrusion Control Capability

The 10/100 Managed Hub provides MAC Address based Security Intrusion Control Capability to prevent any unauthorized nodes access to the network. You can configure the hub to take various actions when a violation is detected. Actions include: no action, sending a trap message or partitioning a port.

Broadcast Storm Detection and Protection Capability

The 10/100 Managed Hub provides Broadcast Storm Detection and Protection Capability by periodically monitoring the broadcast counters of each port to detect a broadcast storm. Ports detected causing a broadcast storm are automatically partitioned, a trap is sent to the network manager, or no action is taken, depending on the configuration.
