CONFIGURING THE SWITCH

Changing the Aging Time

You can set the aging time for entries in the dynamic address table.

Command Attributes

•Aging Status – Enables/disables the function.

•Aging Time – The time after which a learned entry is discarded. (Range: 10-30000 seconds; Default: 300 seconds)

Web – Click Address Table, Address Aging. Specify the new aging time, click Apply.

Figure 3-55 Setting the Address Aging Time

CLI – This example sets the aging time to 400 seconds.

Spanning Tree Algorithm Configuration

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
