Using the BayStack 450 10/100/1000 Series Switch

Choosing a High Speed Flow Control Mode

The High Speed Flow Control feature allows you to control traffic and avoid 
congestion on the gigabit full-duplex link. If the receive port buffer becomes full, 
the BayStack 450 switch issues a flow-control signal to the device at the other end 
of the link to suspend transmission. When the receive buffer is no longer full, the 
switch issues a signal to resume the transmission.

You can choose Symmetric or Asymmetric flow control mode:

Symmetric Mode

This mode allows both the gigabit MDA port and its link partner to send flow 
control pause frames to each other.

Autonegotiation

When enabled, the port only advertises support for 1000 Mb/s operation, in 
full-duplex mode.

Default Value

Enabled

Range

Enabled, Disabled

Flow Control

Allows you to control traffic and avoid congestion on the gigabit MDA port. Two 
modes are available (see 

“Choosing a High Speed Flow Control Mode

” on 

page 3-36

 for details about the two modes). Autonegotiation must be disabled 

for this port when using this feature.

Default Value

Disabled

Range

Disabled, Symmetric, Asymmetric

Note: 

The following two fields only appear when a (single MAC) MDA with a 

separate redundant Phy port is installed.

Preferred Phy

Allows you to choose the preferred Phy port; the other Phy port reverts to 
backup.

Default Value

Right

Range

Right, Left

Active Phy

Indicates the operational Phy port.
