Chapter 1 Configuring Interfaces and Circuits

Configuring Interfaces

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.

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.

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.

•phy 100Mbits-HD- Sets the Fast Ethernet port to 100 Mbps and half-duplex mode.

•phy 1Gbits-FD-asym- Sets the Gigabit Ethernet port to full-duplex mode with asymmetric pause frames transmitted toward the link partner. Asymmetric pause is useful when you need the CSS to pause its link partner but not to respond to pause frames transmitted from the link partner.

•phy 1Gbits-FD-no pause - Sets the Gigabit Ethernet port to full-duplex mode with no pause frames transmitted or received.

•phy 1Gbits-FD-sym- Sets the Gigabit Ethernet port to full-duplex mode with symmetric pause (pause frames transmitted and received by the CSS). Symmetric pause is useful for point-to-point links. By default, all Gigabit Ethernet ports are configured to full-duplex mode with symmetric pause.
