Brocade FastIron Ethernet Switch Administration Guide - Manual (Page 62)

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.
device(config)
# link-config gig copper autoneg-control 10m ethernet 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.
device(config)
# link-config gig copper autoneg-control 100m ethernet 2
Syntax: [no] link-config gig copperautoneg-control [ 10m | 100m ] ethernet port [ ethernet port ]
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.
Configuring port speed down-shift and auto-negotiation for a range of
ports
Port speed down-shift and auto-negotiation can be configured for an entire range of ports with a single
command.
For example, to configure down-shift on ports 0/1/1 to 0/1/10 and 0/1/15 to 0/1/20 on the device, enter
the following.
Brocade(config)# link-config gig copper autoneg-control down-shift ethernet 0/1/1
to 0/1/10 ethernet 0/1/15 to 0/1/20
To configure down-shift on ports 5 to 13 and 17 to 19 on a compact switch, enter the following.
Brocade(config)# link-config gig copper autoneg-control down-shift ethernet 5 to 13
ethernet 17 to 19
Syntax: [no] link-config gig copperautoneg-control [ down-shift | 100m-auto | 10m-auto ]
ethernet port-list
NOTE
The variable represents the list of ports to which the command will be applied.
For , specify the ports in one of the following formats:
• FWS and FCX stackable switches –
• FSX 800 and FSX 1600 chassis devices –
• FESX compact switches –
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a combination
of both. To apply the configuration to all ports on the device, use the keyword all instead of listing the
ports individually.
The output from the show run command for this configuration will resemble the following.
Brocade# show run
