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

port-list
NOTE
The <port-list> variable represents the list of ports to which the command will be applied.
For <port-list>, specify the ports in one of the following formats:
• FWS and FCX stackable switches –
<stack-unit/slotnum/portnum>
• FSX 800 and FSX 1600 chassis devices –
<slotnum/portnum>
• FESX compact switches –
<portnum>
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
Current configuration:

end
To disable selective auto-negotiation of 100m-auto on ports 0/1/21 to 0/1/25 and 0/1/30, enter the
following.
Brocade(config)# no link-config gig copper autoneg-control 100m-auto ethernet
0/1/21 to 0/1/25 ethernet 0/1/30
