upload log

upload log [ ipaddress | hostname] {vr vr_name} {block-size block_size} filename {messages [memory-buffer | nvram] } {severity severity {only}} {match regex} {chronological}

Description

Uploads the current log messages to a TFTP server.

Syntax Description

ipaddress Specifies the ipaddress of the TFTP server.
hostname Host name of server to send log information to.
vr_name
Specifies the virtual router that can reach the TFTP server.
Note: User-created VRs are supported only on the platforms listed for this feature in the Switch Engine v33.1.1 Licensing Guide document.
block_size Specifies the data block size, excluding TFTP header. Data block size ranges from 24-65000 bytes.
filename Specifies the file name for the log stored on the TFTP server.
messages Specifies the location from which to display the log messages.
memory-buffer Show messages stored in volatile memory.
nvram Show messages stored in NVRAM.
severity Specifies the minimum severity level to display (if the keyword only is omitted).
only Specifies that only the specified severity level is to be displayed.
regex Specifies a regular expression. Only messages that match the regular expression will be displayed.
chronological Specifies uploading log messages in ascending chronological order (oldest to newest).

Default

The following defaults apply:
  • messages—memory buffer.
  • severity—none (displays everything stored in the target).
  • match—no restriction.
  • chronological—if not specified, show messages in order from newest to oldest.

If you do not specify block size, the default value is 1400 bytes.

Usage Guidelines

This command is similar to the show log command, but instead of displaying the log contents on the command line, this command saves the log to a file on the TFTP server you specify. For more details on most of the options of this command, see the command show log.
