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.
