Introduction Overview of Managed CenturyStack 8100 Hub The Managed CenturyStack 8100 Hub is a series of auto sensing dual speed, manageable and stackable hubs. The Managed CenturyStack Series consists of masters and managed slaves with 12 or 24 ports. The features and functions of the Managed CenturyStack make it a powerful, cost effective solution for large campus networks and rapid growth companies.
NOTE: The SNMP agent, TCP/IP stack and the Web engine are implemented on the 10Mbps bus of the master hub. Therefore the 10Mbps segment must be used for Web-Based Management in the absence of a switch module. CenturyStack 8100 Managed Hub...
RMON Support RMON is a major step forward in internetwork management. It defines a remote monitoring MIB that supplements MIB-II and provides the network manager with vital information about the internetwork. The Managed CenturyStack Hub Series fully supports RMON Management Groups 1, 2, 3, and 9, and users can set up for RMON Management using Web-Based Management, or SNMP Management.
MIB, and an event can trigger an action defined elsewhere in the MIB. An event may also cause informa- tion to be logged in this group and may cause an SNMP trap message to CenturyStack 8100 Managed Hub...

be issued. Managed CenturyStack RMON Management enables users to set up Event Groups. The Event Group Implementation of the Event Group is optional. The Event Group controls the generation and notification of events from the hub. Each entry in the event Table describes the parameters of the event that can be triggered.
Before the CenturyStack Web Management feature can be used, users must configure the hub’s Network Configurations. See “Network Configu- ration” in the Lancast CenturyStack Series 8100 Managed Installation and User Guide. Users need a Web browser and must be either connected to the World Wide Web (for remote connections) or have an Ethernet connection to a hub in the stack (for in-band connections).
