clear counters segment
Use the clear counters segment command to clear a segment counter of the hub backplane. Other hubs connected to the backplane of the cleared device also clears the relative counter of the same segment.
clear counters segment {10M | 100M}
10M | A backplane segment of 10-Mbps line speed. |
100M | A backplane segment of 100-Mbps line speed. |

Use the copy tftp privileged EXEC command to download an operation code file from the Trivial File Transport Protocol (TFTP) server.
copy tftp://[host/src_file] opcode [temporary | permanent]
host | IP address of the TFTP server. If host is omitted, system attemps to use the host information set by the command tftp server. |
src_file | Operational firmware filename. Filename can be up to 80 characters long. If src_file is omitted, system attempts to use the host information set by command tftp filename. |
temporary | Download the operational firmware to RAM. |

Privileged EXEC
If users do not specify host, src_file name, or download mode, the default host IP, src_file name, and download mode are the same as those specified in the tftp server, tftp filename, and upgrade mode commands.
When downloading an operation code file, the entire system (including other CLI sessions) is inactive for about 30 seconds after the file is retrieved.
This example shows how to download the new system operational code op.bin from host IP address 210.68.150.15 by using the mode specified by the upgrade mode command.

If users do not specify the src_file name or the download mode, the src_file name, and download mode are the same as those specified in the tftp filename and upgrade mode commands.
The downloaded file executes immediately. You cannot enter any new information or commands until the download is completed. After downloading operation code file, the entire system (including other CLI sessions) is inactive for about 30 seconds.
This example shows how to download new system operational code by using the upgrade mode set by the upgrade mode command. The file name is assigned by the tftp filename command.

The access-level default for initial login is 1. The default access level after login is 15.
Privileged EXEC
If a password is configured, you are prompted for the password:

This example shows how to display the summary of command-line entries.
hostname> help Help may be requested at any point in a command by entering a question mark `?'. If nothing matches, the help list will be empty and you must backup until entering a `?' shows the available options. Two styles of help are provided: 1. Full help is available when you are ready to enter a command argument (e.g. `show ?') and describes each possible argument. 2. Partial help is provided when an abbreviated argument is entered and you want to know what arguments match the input. (e.g. `show pr?')

password-thresh threshold
threshold | A value between zero and 65500 password attempts. |
The default value is three attempts.
Line configuration
When the logon attempt threshold is reached, the hub interface becomes silent for a user-defined amount of time before allowing the next logon attempt. See silent-time command to set this time interval.
This example shows how to set the password attempt threshold to 5.
hostname# line console hostname(line-config)# password_thresh 5
Use the ping user EXEC command to test the connectivity between the hub and a connected host. The ping command sends an ICMP echo message (ping) to the specified IP address.

Use the port-speed hub-interface-configuration command to select the way in which a selected port adjusts its port speed to that of its neighbor.
port-speed {auto | 100M | 10M}
auto | Auto-negotiation mode. |
100M | 100-Mbps mode only. |
10M | 10-Mbps mode only. |
The default setting is auto.
Interface configuration
Use auto mode when you want the port to automatically adjust to more than one connecting device. This mode first attempts to connect at 100-Mbps. If that attempt fails, the port operates at 10-Mbps. This process repeats at each change in link status.
This example shows how to set port 4 of hub 1 to operate exclusively at 100-Mbps.
hostname(config)# hub 1 hostname(config-hub)# interface fastethernet 0/4 hostname(config-hub-if)# port-speed 100M
