Configuring Interfaces
Note If you configure the redundancy-phy command on an interface of the master
CSS in a box-to-box redundancy configuration and then make a change to the port
settings of that interface using the phy command (for example, changing
auto-negotiate to 100Mbits-FD), the master CSS fails over to the backup CSS.
To prevent the failover from occurring, first enter the no redundancy-phy
command on the interface, change the port settings, and then reenter the
redundancy-phy command. For information about the redundancy-phy
command, refer to the Cisco Content Services Switch Redundancy Guide.
Use the phy command to configure the duplex, speed (Fast Ethernet ports only),
and flow control (Gigabit Ethernet ports only) for the interface ports, as follows:
•phy auto-negotiate - Resets the Fast Ethernet and Gigabit Ethernet ports to
automatically negotiate port speed and duplex of incoming signals. The CSS
1000BASE-T Gigabit Ethernet port supports 1000 Mbps full-duplex
operation only and does not support auto-negotiation.
Note Pause mode during auto-negotiation is not supported for the Fast Ethernet
ports.
•phy auto-negotiate {enable | disable} - Disables the Gigabit Ethernet
interface from automatically negotiating duplex of incoming signals. By
default, auto-negotiation is enabled for all Gigabit Ethernet ports. The CSS
1000BASE-T port supports 1000 Mbps full-duplex operation only and does
not support auto-negotiation.
Gigabit Ethernet port auto-negotiation remains enabled when a pause mode
command is specified so the Gigabit Ethernet interface ports can act upon the
link partner’s flow control capability. If it is necessary to disable
auto-negotiation for the Gigabit Ethernet port when using a pause mode, enter
the phy auto-negotiate disable command.
•phy 10Mbits-FD - Sets the Fast Ethernet port to 10 Mbps and full-duplex
mode.
•phy 10Mbits-HD - Sets the Fast Ethernet port to 10 Mbps and half-duplex
mode.
•phy 100Mbits-FD - Sets the Fast Ethernet port to 100 Mbps and full-duplex
mode.
