Switching

This section outlines the Layer 2 and IP switching features on the switch, and how to configure some of them. For more detail, refer to the Switching and Internet Protocol (IP) chapters in the AT-8700XL Series Switch Software Reference.

Switch Ports

Each switch port is uniquely identified by a port number. The switch supports a number of features at the physical level that allow it to be connected in a variety of physical networks. This physical layer (layer 1) versatility includes:

■Enabling and disabling of ports.

■Auto negotiation of port speed and duplex mode for all 10/100 BASE ports.

■Manual setting of port speed and duplex mode for all 10/100 BASE ports.

■Link up and link down triggers.

■Port trunking.

■Packet storm protection.

■Port mirroring.

■Support for SNMP management

Enabling and Disabling Switch Ports

An switch port that is enabled is available for packet reception and transmission. Its administrative status in the Interfaces MIB is UP. Disabling a switch port does not affect the STP operation on the port. Enabling a switch port will allow the port to participate in spanning tree negotiation. A switch port that has been disabled by the Port Security feature cannot be enabled using the ENABLE SWITCH PORT command.

To enable or disable a switch port, use the commands:

ENABLE SWITCH PORT={port-listALL}

DISABLE SWITCH PORT={port-listALL}
