based on link availability.
Enabling Port Speed Down-Shift
To enable port speed down-shift on a port that has auto-negotiation enabled, enter a command such as the
following at the Global CONFIG level of the CLI:
FESX424 Switch(config)# link-config gig copper autoneg-control down-shift e 1 e 2
The above command configures Gigabit copper ports 1 and 2 to establish a link at 1000 Mbps over a 4-pair wire
when possible, or to down-shift (reduce the speed) to 100 Mbps when the medium is a 2-pair wire.
Syntax: [no] link-config gig copper autoneg-control down-shift ethernet [<slotnum>/]<portnum> [ethernet
[<slotnum>/]<portnum>]
You can enable port speed down-shift on one or two ports at a time.
To disable port speed down-shift after it has been enabled, enter the no form of the command.
Configuring Maximum Port Speed Advertisement
To configure a maximum port speed advertisement of 10 Mbps on a port that has auto-negotiation enabled, enter
a command such as the following at the Global CONFIG level of the CLI:
FESX424 Switch(config)# link-config gig copper autoneg-control 10m e 1
To configure a maximum port speed advertisement of 100 Mbps on a port that has auto-negotiation enabled, enter
the following command at the Global CONFIG level of the CLI:
FESX424 Switch(config)# link-config gig copper autoneg-control 100m e 2
Syntax: [no] link-config gig copper autoneg-control 10m | 100m ethernet [<slotnum>/]<portnum> [ethernet
[<slotnum>/]<portnum>]
You can enable maximum port speed advertisement on one or two ports at a time.
To disable maximum port speed advertisement after it has been enabled, enter the no form of the command.
Modifying Port Duplex Mode
You can manually configure a 10/100 Mbps port to accept either full-duplex (bi-directional) or half-duplex (uni-
directional) traffic.
NOTE: You can modify the port duplex mode of copper ports only. This feature does not apply to fiber ports.
Port duplex mode and port speed are modified by the same command.
Configuration Syntax
To change the port speed of interface 8 from the default of 10/100/1000 auto-sense to 10 Mbps operating at full-
duplex, enter the following:
FESX424 Switch(config)# interface e 8
FESX424 Switch(config-if-e1000-8)# speed-duplex 10-full
Syntax: speed-duplex <value>
The <value> can be one of the following:
• 10-full
• 10-half
• 100-full
• 100-half
• auto
The default is auto.
