Using the Console Interface

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
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 3-16 ) allows you to
select the appropriate screen to configure up to six MultiLink trunks (you can
group up to four switch ports together 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 1-57 .
Choose MultiLink Trunk Configuration (or press t) from the Switch Configuration
Menu screen to open the MultiLink Trunk Configuration Menu screen.
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.
