Using the BayStack 410-24T 10BASE-T Switch

Symmetric Mode

This mode allows both the gigabit MDA port and its link partner to send flow-control pause frames to each other. When a pause frame is received (by either the gigabit MDA port or its link partner), the port suspends transmission of frames for a number of slot times specified in the control frame or until a pause-release control frame is received. Both devices on the link must support this mode when it is selected.

Asymmetric Mode

This mode allows the link partner to send flow control pause frames to the gigabit MDA port. When a pause frame is received, the receiving port suspends transmission of frames for a number of slot times specified in the control frame or until a pause-release control frame is received.

In this mode the gigabit MDA port is disabled from transmitting pause frames to its link partner. Use this mode when the gigabit MDA port is connected to a buffered repeater device.

MultiLink Trunk Configuration

The MultiLink Trunk Configuration Menu screen (Figure 3-24) allows you to select the appropriate screen to configure up to six MultiLink trunks (you can group up to four switch ports to form each trunk).

You can configure up to six MultiLink trunks in each stack, with trunk members in either a single unit or distributed between units within the stack configuration (distributed trunking).

You can monitor the bandwidth usage for the trunk member ports within each trunk. For more information about configuring MultiLink Trunks, see “MultiLink Trunks” on page 1-63.

Note: When a trunk is not active (Trunk Status field set to Disabled), configuration changes do not take effect until you set the Trunk Status field to Enabled.

Choose MultiLink Trunk Configuration (or press t) from the Switch Configuration Menu screen to open the MultiLink Trunk Configuration Menu screen.
