Command Line Interface

Command Usage
• The 1000BASE-T standard does not support forced mode. Auto-negotiation
should always be used to establish a connection over any 1000BASE-T port
or trunk. If not used, the success of the link process cannot be guaranteed
when connecting to other types of switches. However, this switch does
provide a means of forcing a link to operate at 1000 Mbps, full-duplex using
the giga-phy-mode command.
• To force 1000full operation requires the ports at both ends of a link to establish
their role in the connection process as a master or slave. Before using this
feature, auto-negotiation must first be disabled, and the Speed/Duplex
attribute set to 1000full. Then select compatible Giga PHY modes at both
ends of the link. Note that using one of the preferred modes ensures that the
ports at both ends of a link will eventually cooperate to establish a valid
master-slave relationship.
Example
This forces the switch port to master mode on port 24.
shutdown
This command disables an interface. To restart a disabled interface, use the no
form.
Syntax
[no] shutdown
Default Setting
All interfaces are enabled.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
This command allows you to disable a port due to abnormal behavior
(e.g., excessive collisions), and then reenable it after the problem has been
resolved. You may also want to disable a port for security reasons.
Example
The following example disables port 5.
Console(config)#interface ethernet 1/24
Console(config-if)#no negotiation
Console(config-if)#
speed-duplex 1000full
Console(config-if)#giga-phy-mode master
Console(config-if)#
Console(config)#interface ethernet 1/5
Console(config-if)#shutdown
Console(config-if)#
