13 - 4 Aironet 340 Series Bridge When starting a telnet session with the connect option: n Make sure the telnet option on the remote is enabled before connecting to a remote bridge or client. See “Telnet Access” in Chapter 2. n A message is printed on the remote’s Console stating where the connections originated from. The Console is then disabled for the duration of the telnet session to prevent conflicting commands. n The remote’s Console privilege is set to the highest level that does not have a password. While the unit is attempting to connect to the remote node, the connection can be terminated by typing “CTRL-C”. This may be required if the incorrect address was entered. After connecting, you can close a telnet session and return to the local console by: n Typing the escape sequence of characters as defined by the escape option in the Diagnostics Menu. See “Changing the Escape Sequence”. n If the remote node is an Aironet node, choose the close option which is accessible on the Console Port Main Menu during a telnet session only. n Using the remote node’s logout command. Changing the Escape Sequence (Escape) Use the escape option to change the sequence of characters that are assigned to close a telnet session to a remote destination. Typically, you would change the sequence if the current sequence has meaning to the remote system. The sequence may be up to 10 characters in length. To enter nonprintable characters in the sequence you may: n Use the two-character combination of caret (^) and the alphabetic character corresponding to the control character. For example, to enter “control Z”, use the string “^Z”. n Use a backslash “\” followed by three octal numbers n Use a dollar sign “$” followed by two hexadecimal numbers
Physically Locating a Unit (Find) Performing Diagnostics 13 - 5 Use the find option to blink the amber indicators of the bridge on and off. Find a unit you can telnet to if you are not sure of it’s exact location. Type “CTRL-C” to stop the command. Sending a Ping Packet (Ping) Use the ping option to test infrastructure connectivity from the bridge to other IP nodes. The ping option sends an ICMP echo_request packet to a user-specified remote node. If the remote node receives the packet it will also respond with an ICMP echo_response packet. The Aironet 340 Series Bridge will send the echo_response packet and wait 3 seconds for a response. If none is received, another echo packet is sent. This is repeated up to five times. If a response is received and a message is displayed, the command disappears from the screen. Type “CTRL-C” to stop the command. Loading New Firmware and Configurations (Load) The Aironet 340 Series Bridge code and configuration are stored in a flash memory chip inside the unit. Use the load option to load new code versions of the Aironet 340 Series Bridge’s firmware or configurations and save them to flash memory. To load new versions of the firmware, the code must be loaded into main memory first, then programmed into the flash memory. The unit will reboot using the new firmware. The flash memory will retain the new version even if the power is disconnected. If the file downloaded begins with the string “! CONFIGURATION” then the file is considered to be a text file with lines of commands that are executed as though the were typed at the console. The new firmware or configuration can be downloaded into the unit using: n FTP: Load the new file into a single unit using either the Xmodem or FTP protocols. Then use the FTP protocol to upload (send) the file from the local unit to other remote units on the infrastructure. n Distribute: Load the new file into a single unit using either the

Physically Locating a Unit (Find)<br />
Performing Diagnostics 13 - 5<br />
Use the find option to blink the amber indicators of the bridge on and<br />
off. Find a unit you can telnet to if you are not sure of it’s exact location.<br />
Type “CTRL-C” to stop the command.<br />
Sending a Ping Packet (Ping)<br />
Use the ping option to test infrastructure connectivity from the bridge to<br />
other IP no<strong>de</strong>s. The ping option sends an ICMP echo_request packet to a<br />
user-specified remote no<strong>de</strong>. If the remote no<strong>de</strong> receives the packet it<br />
