Cisco Systems OL-4580-01 manual Setting Interface Maximum Idle Time

Chapter 1 Configuring Interfaces and Circuits

Configuring Interfaces

•phy 1Gbits-FD-sym-asym- Sets the Gigabit Ethernet port to full-duplex mode with symmetric and asymmetric pause frames used with the local device.

For example, to configure Fast Ethernet interface 1 on the I/O module in slot 2 of the CSS 11503 to 100 Mbps and half-duplex mode, enter:

(config-if[2/1])# phy 100Mbits-HD

For example, to configure gigabit interface 1 on the SCM in slot 1 of the

CSS 11503 to full-duplex mode with asymmetric pause, enter:

(config-if[1/1])#phy auto-negotiate disable

(config-if[1/1])# phy 1Gbits-FD-asym

Setting Interface Maximum Idle Time

As a troubleshooting tool to verify an interface’s ability to receive traffic, use the max-idlecommand. If the interface does not receive traffic within the configured idle time, the CSS reinitializes the interface automatically.

Set the idle time to a value greater than the interval over which the interface is receiving traffic. For example, if the interface receives traffic every 90 seconds, set the idle time to a value greater than 90 seconds. If you set the idle time to less than 90 seconds, the CSS would continuously reinitialize the interface before the interface was able to receive traffic.

Enter an idle time from 15 to 65535 seconds. The default is 0, which disables the idle timer.

For example, to set the maximum idle time to 180 seconds for interface port 1 on a CSS 11503, the I/O module in slot 2, enter:

(config-if[2/1])# max-idle 180

To reset the idle time for an interface to its default value of 0, enter:

(config-if[2/1])# no max-idle
