Generic header ID in configuration file

Auto deployment relies on DHCP options and the current DHCP auto-configuration function. Auto deployment is platform independent, avoiding the J-number validation of the downloaded configuration file when downloaded using DHCP option 66/67. The downloaded configuration file has an IGNORE tag immediately after the J-number in its header.

An option to add an add-ignore-tag to an existing copy command will insert an ignore tag into the configuration header. This insertion happens while transferring the configurations, (startup configuration filesand running configuration files) from the switch to a configuration file setup on a remote server. The process uses TFTP/SFTP or can be accomplished with a serially connected workstation using XMODEM.

The add-ignore-tag option is used in conjunction with the copy command to transfer the startup configuration or running configuration files from the switch to a remote server with IGNORE tag inserted into it.

The IGNORE tag is inserted into the first line of the configuration file directly after the J-number.

	NOTE: The J-number validation is ignored only when configuration file that contains the IGNORE tag is downloaded to a switch via DHCP option 66/67. When a configuration file containing the IGNORE tag is downloaded to a switch using CLI, SNMP or WebUI, the downloaded configuration file is only accepted if the J-number in it matches the J-number on the switch.

There is no change to the current switch configuration when executing the copy command with the add-ignore-tag option. The IGNORE tag is only added to the configuration file being exported to the external server. The configuration file stored on an external server is then downloaded to the switch using DHCP option 66 during bootup. If the IGNORE tag is available in the downloaded configuration file then the switch will avoid the J-number validation of the configuration file. The downloaded configuration file will then go through a line by line validation. Once the configuration file passes this validation, it gets updated in the flash. Once the configuration file has been updated, the switch will reboot automatically.

	NOTE: The J-number in the downloaded configuration file is replaced with that of the switch. The IGNORE tag is removed from the downloaded configuration file before updating it to flash. The show running-configuration command will not display the IGNORE tag but displays the switch’s J-number as part of the output.

HPN Switch(config)# copy startup-config tftp <ip-addr> <filename> add-ignore-tag
HPN Switch(config)# copy running-config tftp <ip-addr> <filename> add-ignore-tag
HPN Switch(config)# copy startup-config sftp <ip-addr> <filename> add-ignore-tag
HPN Switch(config)# copy running-config sftp <ip-addr> <filename> add-ignore-tag
HPN Switch(config)# copy startup-config xmodem add-ignore-tag
HPN Switch(config)# copy running-config xmodem add-ignore-tag

Configuration files can be transferred to the switch from a server using the following copy commands:

copy tftp < startup-config | running-config > < ip-address > < remote-file >[ pc | unix ]
copy xmodem startup-config < pc | unix >
copy sftp < startup-config | running-config > < ip-address > < remote-file >

Configuration files that are downloaded using the copy commands as described in the example will be accepted by the switch if they pass J-number validations and line by line validations after download. The downloaded configuration file will be discarded by the switch if the validations fail. If the validations fail, the switch will work with it’s previous configuration.

The show logging command is used to locate errors during a configuration validation process. The event log catalogs entries with the ID#00158 and updates for each invalid entry found in the configuration file.

	NOTE: Downloading manually edited configuration file is not encouraged.

The IGNORE tag is not an available option when using external SCP, SFTP or TFTP clients such as PuTTY™, Open SSH™, WinSCP™ and SSH Secure Shell™ to transfer configuration files out of the switch.
