before. (Although you cannot set a global default for Gigabit Ethernet negotiation in software releases earlier than
05.2.00, the implicit default behavior is negotiation-off.)
If the startup-config file contains the auto-gig command to configure individual ports for auto-Gigabit, the
command is changed to the new format, gig-default auto-gig. Thus, the ports continue to use the auto-Gigabit
setting.
NOTE: Software release 05.2.00 and later also adds a version line to the running-config file on Stackable
devices. However, the command syntax and default behavior for Gigabit Ethernet ports on Stackable devices is
unchanged from earlier software releases.
Changing the Negotiation Mode
You can change the negotiation mode globally and for individual ports. Use either of the following methods.
USING THE CLI
To change the mode globally, enter a command such as the following:
BigIron(config)# gig-default neg-off
This command changes the global setting to negotiation-off. The global setting applies to all Gigabit Ethernet
ports except those for which you set a different negotiation mode on the port level.
To change the mode for individual ports, enter commands such as the following:
BigIron(config)# int ethernet 4/1 to 4/4
BigIron(config-mif-4/1-4/4)# gig-default auto-gig
This command overrides the global setting and sets the negotiation mode to auto-Gigabit for ports 4/1 – 4/4.
Here is the syntax for globally changing the negotiation mode.
Syntax: gig-default neg-full-auto | auto-gig | neg-off
Here is the syntax for changing the negotiation mode on individual ports.
Syntax: gig-default neg-full-auto | auto-gig | neg-off
USING THE WEB MANAGEMENT INTERFACE
To change the global default:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Select the Advance link to display the advanced System parameters panel.
3. Select one of the following values from the Gig Port Default field's pulldown menu:
• Neg-off – The port does not try to perform a handshake. Instead, the port uses configuration information
manually configured by an administrator.
• Auto-Gig – The port tries to perform a handshake with the other port to exchange capability information.
• Neg-Full-Auto – The port first tries to perform a handshake with the other port to exchange capability
information. If the other port does not respond to the handshake attempt, the port uses the manually
configured configuration information (or the defaults if an administrator has not set the information).
4. Click Apply to save the changes to the device's running-config file.
5. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
To override the global negotiation mode for an individual port:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to display the configuration options.
