Module Features

When you install the Switch 208/224 Management Module in your Switch 208T or 224T, you get these enhanced switch capabilities:

Full-duplex port operation. By default, the 10 Mbit/s and

100 Mbit/s ports on the Switch 208/224 operate in half-duplex mode. With the Switch Management Module installed, these ports can be configured to operate in full-duplex mode.

Address Aging. The Switch 208/224 automatically learns the MAC address of the devices connected to its ports and stores those address- es in an 8000-entry address table. When a device is moved, its new location is automatically learned and kept in the table so proper communication is maintained with the device. With the Management Module installed, the additional benefit is that inactive addresses are aged out of the table -- the table is kept up to date with the addresses of active nodes only.

Spanning Tree Support. The Switch 208/224 uses the IEEE 802.1d Spanning Tree Protocol (STP) to ensure that only one path at a time is active between any two nodes in the network, thus preventing loops that cause broadcast storms from occurring in the network topology.

By default, STP is disabled on the switch. You can use the switch console to enable STP operation; see chapter 4, “Configuring the Switch From the Console” for those configuration procedures. For more information on how STP works, see appendix D, “Spanning Tree Operation”.

Switch Console. The Management Module has an RS-232 port to which you can connect a console that can be used to configure, monitor, and troubleshoot the switch and its ports. The console interface can be used “out-of-band” from a PC or terminal directly connected to the port or remotely through a modem connection, or “in-band” through a Telnet session. For more information on the switch console, see the section “Switch Console Features” in chapter 3, “The Switch Console”.

Network Management. The Management Module has firmware agents on board that provide SNMP Network Management control of the switch, support for RMON (four groups) and HP Embedded Advanced Sampling Environment (EASE) agents to diagnose net- work problems to help optimize network performance. For more information the network management features provided by the Man- agement Module and how to configure those features, see chapter 6, “Using SNMP to Monitor and Manage the Switch”.
