Introduction 11
Redundant Link Capacity
Redundant links can be configured enabling up to 24 pairs in a
CenturyStack. 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
CenturyStack 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
CenturyStack 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
CenturyStack 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
CenturyStack 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.
