Configuring the MSS DHCP Server

MSS has a DHCP server that the switch uses to allocate IP addresses to the following. DHCP service for these items is enabled by default.

„Directly connected MAPs

„Host connected to a new (unconfigured) WXR100 or WX1200, to configure the switch using the Web Quick Start

Optionally, you can configure the DHCP server to also provide IP addresses to Distributed MPs and to clients.

Use of the MSS DHCP server to allocate client addresses is intended for temporary, demonstration deployments and not for production networks. 3Com recommends that you do not use the MSS DHCP server to allocate client addresses in a production network.

To enable the MSS DHCP server on the VLAN:

1In the Create VLAN wizard, click DHCP Server. The DHCP Server page appears.

2Select Enabled.

3To change the range of addresses available to the DHCP server, edit the addresses in the Start IP Addresses and Stop IP Addresses boxes.

By default, all addresses except the host address of the VLAN, the network broadcast address, and the subnet broadcast address are included in the range. If you specify the range, the start address must be lower than the stop address, and all addresses must be in the same subnet. The IP interface of the VLAN must be within the same subnet but is not required to be within the range.

4To close the wizard and save the changes, click Finish.

Configuring STP Fast Convergence Features

The standard STP timers delay traffic forwarding briefly after a topology change. The time a port takes to change from the listening state to the learning state or from the learning state to the forwarding state is called the forwarding delay. In some configurations, this delay is unnecessary.

The WX switch provides the following fast convergence features to bypass the forwarding delay:

„Backbone fast convergence

„Uplink fast convergence
