Updates to the Software Configuration Guide

These are the documentation updates for the software configuration guide:

• “Understanding Flex Links and the MAC Address-Table Move Update Chapter” section on page 19

• “Configuring IEEE 802.1x Port-Based Authentication Chapter” section on page 19

• “Configuring System Message Logging Chapter” section on page 20

Understanding Flex Links and the MAC Address-Table Move Update Chapter

This information in the “MAC Address-Table Move Update” section of the “Understanding Flex Links

and the MAC Address-Table Move Update” chapter of the software configuration guide is incorrect:

The switch then starts forwarding traffic from the server to the PC through port 4, which reduces

the loss of traffic from the server to the PC.

This is the correct information:

Switch A does not need to wait for the MAC address-table update. The switch detects a failure

on port 1 and immediately starts forwarding server traffic from port 2, the new forwarding port.

This change occurs in 100 milliseconds (ms). The PC is directly connected to switch A, and the

connection status does not change. Switch A does not need to update the PC entry in the MAC

address table.

Configuring IEEE 802.1x Port-Based Authentication Chapter

This information about the dot1x timeout tx-period seconds interface configuration command is

incorrect:

The range for seconds is from 5 to 65535.

The correct range is from 1 to 65535 seconds.
