Release Notes for the Cisco ME 3400 Ethernet Access Switch, Cisco IOS Release 12.2(44)SE
OL-14632-01
Upgrading the Switch Software
You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a
host by using the copy flash: tftp: privileged EXEC command.
You can also configure the switch as a TFTP server to copy files from one switch to another without
using an external TFTP server by using the tftp-server global configuration command. For more
information about the tftp-server command, see the “Basic File Transfer Services Commands” section
of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 at this URL:

Upgrading a Switch
This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a
TFTP server and extract the files. You can download an image file and replace or keep the current image.
Note For downloading software, we recommend that you connect to the TFTP server through a network node
interface (NNI). If you want to connect to the server through a user network interface (UNI), see the
“Troubleshooting” chapter of the software configuration guide for methods for enabling ping capability
on UNIs. See the “New Software Features” section on page 6 for a definition of NNIs and UNIs.
To download software, follow these steps:
Step 1 Use Table 2 on page 3 to identify the file that you want to download.
Step 2 Download the software image file. If you have a SmartNet support contract, log in to cisco.com and go
to this URL, and log in to download the appropriate files:

Click on “Launch the IOS Upgrade Planner” and search for ME 3400 to download the appropriate files:
• To download the metro base, metro access, or metro IP access files for a Cisco ME 3400 switch,
click Cisco ME 3400 software.
• To obtain authorization and to download the cryptographic software files, click Cisco ME 3400
3DES Cryptographic Software.
Step 3 Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP
server is properly configured.
For more information, refer to Appendix B in the software configuration guide for this release.
Step 4 Log into the switch through the console port or a Telnet session.
Step 5 (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC
command:
Switch# ping tftp-server-address
Note By default, ping is supported on network node interfaces (NNIs), but you cannot ping from a
user network interface (UNI) because the control-plane security feature drops ICMP response
packets received on UNIs. See the “Troubleshooting” chapter of the software configuration
guide for methods for pinging from the switch to a host connected to a UNI.
