Using the Web-based Management Software
56
To configure port settings for any module, first select the
Slot
from the drop-down menu, then which
ports are to be configured in the
From
and
To
drop-down menus. See the table below for a summary
of the management options for the available switch modules.
Each port or range of ports can be configured for the following parameters in the Port Configuration
menu:
State
(all ports on DES-7005,
DES-7006 and DES-7010
modules)
Enable or disable the port or ports. If you choose
Disabled
in the
State
field, devices connected to that port cannot use the Switch, and the
Switch purges their addresses from its address table after the MAC
address aging time elapses.
Speed/Duplex
(all ports on DES-7005
module; DES-7006 ports
operate at 100 Mbps and
full duplex only)
Select
Auto
for Auto-negotiation. This allows the port to select the best
transmission speed and duplex mode based on the capabilities of the
device at the other end. Select
100M/Full
for port operation at 100
Mbps and full duplex. Select
100M/Half
for port operation at 100 Mbps
and half duplex. Select
10M/Full
for port operation at 10 Mbps and full
duplex. Select
10M/Half
for port operation at 10 Mbps and half duplex.
Flow Control
(all ports on DES-7005
and DES-7006 modules)
Selecting
Enabled
in full-duplex mode will implement IEEE 802.3x flow
control. Selecting
Enabled
when the port is in half duplex mode will
implement normal Ethernet collision-based backpressure flow control.
Select
Disabled
for no flow control.
Learning
(all ports on DES-7005,
DES-7006 and DES-7010
modules)
Enable or disable learning for the selected ports. When
Enabled
,
destination and source MAC addresses are automatically listed in the
forwarding table. When learning is
Disabled
, MAC addresses must be
manually entered into the forwarding table. This is sometimes done for
reasons of security or efficiency. See the section titled Forwarding and
Filtering on page 65 for information on entering MAC addresses into
the forwarding table.
Downstream
(all ports on DES-7010
module)
Choose the downstream (Tx) speed for the port (s). To select the port
downstream speed in Mbps, choose
Mode 0, 512K, 1M, 2M, 3M, 4M,
5M, 8M, 10M, 15M
from the drop-down menu. The default downstream
port speed is
Mode 0.
Mode 0 is the default setting for VDSL ports. It
specifies a downstream speed of 4 Mbps.
Upstream
(all ports on DES-7010
module)
Choose the upstream (Rx) speed for the port (s). To select the port
downstream speed in Mbps, choose
Mode 0, 512K, 1M, 2M, 3M, 4M,
5M, 8M, 10M, 15M
from the drop-down menu. The default downstream
port speed is
Mode 0.
Mode 0 is the default setting for VDSL ports. It
specifies an upstream speed of 1 Mbps and downstream speed of 4
Mbps.
Rate Adaptive
(all ports on DES-7010
module)
The VDSL Rate Adaptive feature automatically senses line condition
and adjusts download and upload speeds if a set rate cannot be
maintained. The default setting will set speed to
Mode 0
when a rate
can no longer be supported.
Optimum
setting sets speed to Mode 0 but
then tests raise the download and upload speed incrementally to
achieve the best performance level. This function is configured per port
using a separate menu in the web manager (see page 75).
The CLI command set
config ports
is used for port configuration of ports on the DES-7005 and
DES-7006 switch modules. For configuration of VDSL ports on the DES-7010 switch module use the
CLI command set
config vdsl_ports
.
