Caveats

Cable Insert Might Disable Traffic

With IOS Release 11.2(8.1)SA6, you might experience a problem with traffic flow in one direction
when you insert a cable. To determine if this problem exists, use the ping command on a station
located on one end of the stack to verify connectivity to a station on the other end of the stack.

If this problem exists, you can work around it by doing one of the following:

•

Upgrade the software on your switch to IOS Release 11.2(8.2)SA6 or later on the switch. To
download the software, go to http://www.cisco.com/cgi-bin/tablebuild.pl/<platform-type> if you
are a registered Cisco Connection Online (CCO) user or
http://www.cisco.com/pcgi-bin/tablebuild.pl/<platform-type> if you are a non-registered user.
For information about dowloading and upgrading the software, refer to the Release Notes for the
Catalyst 2900 Series XL and Catalyst 3500 Series XL Cisco IOS Release 11.2(8.2)SA6.

•

Remove the cable from the device and then reinsert it.

•

Enter the following command-line interface (CLI) commands on each switch in the stack that has
this problem:

Step 1

Enter the enable command to access privileged EXEC mode:

Switch> enable

Step 2

Enter global configuration mode by entering the configure t command:

Switch# config t

Step 3

Enter the interface command for the port that is not receiving traffic where x is the port
number that is not receiving traffic:

Switch(config)# interface Gix/y

Step 4

Enter the duplex half command to set the duplex mode to half duplex:

Switch(config-if)# duplex half

Step 5

Wait for a few seconds. The link will come down and go back up.

Step 6

Enter the duplex auto command to set the duplex mode for autonegotiation:

Switch(config-if)# duplex auto

Step 7

Exit the configuration mode by using the end command:

Switch(config-if)# end

Note

It is recommended that you upgrade your software to to IOS Release 11.2(8.2)SA6 or later.
