Allows you to TFTP from the current command line interface session to a TFTP server.
| ip-address | Specifies the IP address of the TFTP server. |
| host-name | Specifies the name of the remote host. |
| vr_name | Specifies the name of the
virtual router. Note: User-created VRs are supported only on the
platforms listed for this feature in the
ExtremeXOS and Switch Engine 31.7 Feature License Requirements
document.
|
| block_size | Specifies the data block size, excluding TFTP header. Data block size ranges from 24-65,000 bytes. Default is 14,00 bytes. |
| -g | Gets the specified file from the TFTP server and copies it to the local host. |
| -p | Puts the specified file from the local host and copies it to the TFTP server. |
| local-file | Specifies the name of the file (configuration file, policy file) on the local host. |
| remote-file | Specifies the name of the file on the remote host. |
If you do not specify a virtual router, VR-Mgmt, and then VR-Default (if needed), is used.
If you do not specify otherwise, the switch downloads or uploads the file from the switch local file system (/usr/local/tmp)..
If you do not specify block size, the default value is 14,00 bytes.
NetASCII and mail file type formats are not supported.
Extreme Networks recommends using a TFTP server that supports blocksize negotiation (as described in RFC 2348, TFTP Blocksize Option) to enable faster file downloads and larger file downloads. If the TFTP server does not support blocksize negotiation, the file size is limited to 32MB. Older TFTP servers that do not support blocksize negotiation have additional implementation limits that may decrease the maximum file size to only 16MB, which may be too small to install ExtremeXOS images.
If your TFTP server does not support blocksize negotiation, the switch displays a message similar to the following when you attempt a get (-g) or put (-p) operation:
Note: The blocksize option is not supported by the remote TFTP server. Without this option, the maximum file transfer size is limted to 32MB. Some older TFTP servers may be limited to 16MB file.
Use TFTP to download a previously saved configuration file or policy file from the TFTP server to the switch. When you download a file, this command does not automatically apply it to the switch. You must specify that the downloaded file be applied to the switch. For example, if you download a configuration file, run the use configuration command to apply the saved configuration on the next reboot. You must run the reboot command to activate the new configuration. If you download a policy file, run the refresh policy command to reprocess the text file and update the policy database.
You also use TFTP to upload a saved configuration file or policy file from the switch to the TFTP server.
If your download from the TFTP server to the switch is successful, the switch displays a message similar to the following:
Downloading megtest2.cfg to switch... done!
If your upload from the switch to the TFTP server is successful, the switch displays a message similar to the following:
Uploading megtest1.cfg to TFTPhost ... done!
Up to eight active TFTP sessions can run on the switch concurrently.
You must configure DNS in order to use the host_name option.
When specifying a host name or remote IP address, the switch permits only the following characters:
When specifying a local or remote file name, the switch permits only the following characters:
The vr_name option specifies the name of the virtual router. The valid virtual router names at system boot-up are VR-Mgmt, VR-Control, and VR-Default; however, you can only TFTP on VR-Mgmt and VR-Default. In ExtremeXOS 10.1, the valid virtual routers are VR-0, VR-1, and VR-2 respectively. For more information about virtual routers, see the Virtual Routers chapter in the ExtremeXOS 31.7 User Guide .
Core dump files have a .gz file extension. The file name format is: core.process-name.pid.gz where process-name indicates the name of the process that failed and pid is the numerical identifier of that process.
If you configure and enable the switch to send core dump (debug) information to internal memory, specify the internal-memory file path /usr/local/tmp to transfer those files from internal memory to a TFTP server.
If the switch has not saved any debug files, you cannot transfer other files to or from internal memory. For example if you attempt to transfer a configuration file from the switch to the internal memory, the switch displays a message similar to the following:
Update: Error: tftp transfer to /usr/local/tmp is not allowed.
For information about configuring and sending core dump information, see the configure debug core-dumps [ off | directory_path] save debug tracefiles directory_path and commands.
For more detailed information about core dump files, see Troubleshooting.
On the ExtremeSwitching series switches and SummitStack, use the download bootrom command to upgrade the BootROM. This command utilizes TFTP to transfer the BootROM image file from your TFTP server to the switch. Only upgrade the BootROM when asked to do so by an Extreme Networks technical representative. For more information about this command, see download bootrom .
To upgrade the image, run the download image command. This command uses TFTP to transfer the software image file from your TFTP server to the switch. For more information about this command, see download image.
The following example downloads the configuration file named XOS1.cfg from the TFTP server with an IP address of 10.123.45.67:
# tftp 10.123.45.67 -v “VR-Default” -g -r XOS1.cfg
The following example uploads the configuration file named XOS2.cfg to the TFTP server with an IP address of 10.123.45.67:
# tftp 10.123.45.67 -v “VR-Default” -p -r XOS2.cfg
The following example downloads a policy file to a USB storage device:
# tftp 10.1.2.3 -g -l /usr/local/ext/test.pol -r august23.pol
