Port Setup
3-9
PACE
Enable/Disable/Unit Default
This field allows you to enable or
disable PACE (Priority Access Control Enabled) on the port:
Enable
— Enabling PACE increases network performance particularly
if you are using multimedia applications. You should only enable
PACE on a port if it is connected to a single end-station, switch,
bridge or router. Setting this field overrides the PACE configuration
specified for the port using the Module Setup screen, see
“Switch
1005 Setup”
starting on page 3-4.
Disable
— You should disable PACE if the port connects to a
repeater.
Unit Default
— The PACE mode for the port is determined by the
unit setting configured on the Module Setu p screen, see
“Switch
1005 Setup”
on page 3-4.
Select VLT Mode
Enable/Disable
This field allows you to specify
whether the port forms par t of a Virtual LAN Trunk (VLT). A Virtual LAN
Trunk is a connection which carries traffic for multiple VLANs between
Switch 1005 modules. You can find more information about VLANs in
Chapter 5
.
Duplex Mode
Half Duplex/Full Duplex
This field allows you to enable
full duplex on Fast Ethernet ports:
Full Duplex
— Full duplex allows packets to be transmitted and
received simultaneously and, in effect, doubles the bandwidth
available on a Fast Ethernet link. For 100BASE-FX links, full duplex
also allows cable runs of up to 2km. You should only enable full
duplex on a point to point link between the Switch and another
device with full duplex support.
Half Duplex
— You should use half duplex if the port connects to a
shared Ethernet LAN segment, or if the device at the ot her end of a
point to point link does not support full duplex.
Intelligent Flow Management (IFM) will not work on a port which uses
full duplex, therefore the Intelligent Flow Management field will be
disabled if full duplex is enabled.
