Configuring SPAN for Port Monitoring on a Set/Clear Command−Based IOS

To configure the Set/Clear command−based IOS switch for SPAN, follow these steps:

1. To enable SPAN, use the set span enable command. The syntax for this command is as follows:

set span enable|disable

2.To enable SPAN for port monitoring, you must identify the source module, source port, destination module, destination port, and (optionally) whether you want it to monitor received frames, transmitted frames, or both. The syntax for the command is as follows:

set span <source module/source port> <destination module/ destination port> [rx|tx|both]

Note RX stands for Receive, TX stands for Transmit.

Configuring SPAN for VLAN Monitoring on a Set/Clear Command−Based IOS

To configure a Set/Clear command−based IOS switch for SPAN, follow these steps:

1. To enable SPAN, use the set span enable command. The syntax for this command is as follows:

set span enable|disable

2.To enable SPAN for VLAN monitoring, you must identify the source VLAN, destination module, destination port, and (optionally) whether you want it to monitor received frames, transmitted frames, or both. The syntax for the command is as follows:

set span <source VLAN> <destination module/ destination port> [rx|tx|both]

Enter Selection:

2.Use the [U] Upgrade Operation Firmware (XMODEM) option to upgrade the firmware (you must be using X−Modem compatible software on the network node attached to the switch):

Enter Selection: U

The XMODEM protocol will be used to perform this firmware upgrade. The user must initiate an XMODEM file transfer from the terminal side using an appropriate terminal application specific command.

Do you wish to continue with the download process, [Y]es or [N]o?

3.By answering [Y]es here, the switch immediately deletes the IOS from the Flash. It doesn’t give you any warning. The configuration is left to run on the new IOS that is installed:

Erasing invalid flash − may take up to 1 minute.

Erasure completed.

4.You now need to select the speed at which to upload the IOS. If you are using the console cable it should be 9600. If you are using a modem you can upload a new image at 57,600Kbps:

Do you wish to upgrade at [9]600 (console speed) or [5]7600? 9600

Waiting for image at the configured baud rate…
