Switch Management and Operating Concepts

•Back pressure—The switch fakes a collision and then transmits a jam sequence to ensure all stations are notified of the “collision.” This causes the sending ports to trigger their back-off routines and reduces the amount of traffic on the port.

The port type and duplex mode determine which type of flow control is used. The following table lists the port types and their flow control methods.

Port Security and MAC Address Learning

For security purposes, you can disable MAC address learning on one or more ports. When MAC address learning is disabled, a port uses the first packet received as a permanent address and accepts broadcast traffic and packets from only that one MAC address. New addresses will not be learned.

The default value for each port is learning enabled.

SNMP

The switch has an embedded Simple Network Management Protocol (SNMP) agent which is compliant with SNMP v1 and SNMP v2c. This agent monitors the status of the board's hardware and the traffic passing through its ports. A computer attached to the network, called a management station, can access this information. The switch uses the following features to control access to its information:

•Community strings-You can configure up to four community strings so that only authorized management stations can access the agent. You can set each string to grant either read only or read/write access.

•IP address-You can restrict access to specified IP addresses. You can enter up to three IP addresses which restricts access to these specified management stations.

You can also specify which management agents receive the trap messages generated by the SNMP agent. These trap messages are status messages that alert you of events such as authentication failure, STP topology changes, and link status changes on the port.

The following events will generate an SNMP trap on the ZT 8101 switch:
