XML-PI How to Use XML-PI • brief—Configuration without certificate data • full—Full configuration • interface interface-name—Specified interface output only A full interface specification (interface fastethernet0/0, for example) is required If the interface name does not match one that is supported on the network device, an error is returned The following is a sample command: Router# show running-config brief | format Generating XSD Format for Commands The show xsd-format command is used to display the XSD to which the XML output conforms This section describes how to use this command For example of command output, see “Generating show Command XSD Format: Example” section on page 21 SUMMARY STEPS show xsd-format [location:local-filename] cli command DETAILED STEPS Step show xsd-format [location:local-filename] cli command The location and local-filename arguments are the location and filename of the ODM spec file Valid location keywords are bootflash:, flash:, nvram:, and any valid disk or slot number (for example: disk0: or slot1:) ODM spec files have a odm suffix These arguments are not required if you want to use a default ODM file defined with the format global command The first of the following two examples, displays XSD output from a defined default ODM spec file: Router# show xsd-format cli show arp Router# show xsd-format disk2:spec3.3.odm cli show arp Note When the user is entering command names, the full command name must be entered; not use command truncation Troubleshooting ODM Errors This section describes use of the debug format all command to troubleshoot spec file errors SUMMARY STEPS 14 enable debug format all show-command | format [location:local-filename] XML-PI How to Use XML-PI no debug format all DETAILED STEPS Step enable Enter this command to enable the privileged EXEC mode required to run debug commands Step debug format all Enter this command to enable a verbose debugging mode that displays all ODM errors Step show-command | format [location:local-filename] Enter this command to generate XML output for the show interfaces command The following is sample output: Router# show interfaces | format slot0:spec3.3.odm Selected debug data is displayed with comments followed by the full debug output The debug format statements are read in groups of two lines As the following example shows, the first line describes what the attempted match was; the second line provides the offset and the byte count from the beginning of the show interfaces command output that the cursor of the screen scraper is currently at: *May *May 01:20:35.279: ODM: Could not match Property mcast 01:20:35.279: offset 703: minute output rate bits/sec, packets/sec The following example shows where the SFE caused the ODM algorithm to return a truncated XML Notice how the offset jumps from 703 to 3001 This is a large jump that implies a search between multicast and IP multicast probably caused the screen scraper to jump too far into the text Because the cursor is not at a buffer, this condition is the likely candidate for the error Looking at the spec file entry and doing a manual search through the show command output will confirm this suspicion *May 01:20:35.279: offset 703: minute output rate bits/sec, packets/sec 786 pa *May 01:20:35.279: ODM: Could not match Property mcast *May 01:20:35.279: offset 703: minute output rate bits/sec, packets/sec 786 pa *May 01:20:35.279: ODM: Could not match Property IP multicasts *May 01:20:35.279: offset 3001: no buffer Received broadcasts, runts, giants, *May 01:20:35.279: ODM: Could not match Property watchdog *May 01:20:35.279: offset 3122: ignored, abort packets output, bytes, underru *May 01:20:35.279: ODM: Could not match Property input packets with dribble condition detected Step no debug format all Disable the debug command when troubleshooting is complete Managing Files This section provides the following procedures for managing files in XML-PI: • Displaying Files on a Cisco IOS Filesystem: Example, page 16 15 XML-PI How to Use XML-PI • Managing Spec Files, page 16 • Validating Spec Files, page 17 Displaying Files on a Cisco IOS Filesystem: Example The following example shows how to display a list of files: Router# show format slot0:? slot0:spec3.3.odm Note slot0:spec3.ALR.odm slot0:spec3.empty.odm The question mark (?) command can be used following any of the location keywords (bootflash, slot, and so on) in the show format and show xsd-format commands, to list all files Spec files have a odm file extension Managing Spec Files Use the spec-file install privileged EXEC command to manage the spec files The following commands allow you to make backup copies of the built-in spec file before changing the contents of the file, and to restore the contents of a previous spec file You can also copy and remove SFEs from one spec file to another Valid locations for local files are bootflash:, flash:, nvram:, and any valid disk or slot number (example: disk0: or slot1:) Valid URLs for remote files are archive:, bootflash:, cns:, flash:, ftp:, http:, null:, nvram:, pram:, rcp:, scp:, system:, tar:, tftp:, tmpsys: and any valid disk or slot number (for example, disk0: or slot1:) In all cases, the force keyword performs the command without prompting you to verify the file operation by entering a “yes” or “no” response SUMMARY STEPS 16 spec-file install [force] location:local-filename add-entry url:remote-filename command spec-file install [force] location:local-filename built-in spec-file install [force] location:local-filename file url:remote-filename spec-file install [force] location:local-filename remove-entry command spec-file install [force] location:local-filename restore XML-PI How to Use XML-PI DETAILED STEPS Step Command or Action Purpose spec-file install [force] location:local-filename add-entry url:remote-filename command Copies an SFE from a remote location and adds it to a local spec file • A check is performed on the loaded SFE to ensure that the command is not already present in the spec file, and that the SFE can be parsed correctly in XML • If the spec file does not exist, you will be prompted before the file is created • If the command SFE already exists in the spec file, you will be prompted before the command SFE is replaced • A backup copy of the local spec file is created before the remote SFE is added Example: Router# spec-file install slot0:spec_file.odm add-entry tftp://system1/user1/show_arp.odm show arp Step spec-file install [force] location:local-filename built-in Replaces the current spec file with the built-in spec file • You will be prompted before the current file is replaced and filename.bak will be created Example: Router# spec-file install slot0:spec_file.odm built-in Step spec-file install [force] location:local-filename file url:remote-filename Replaces a local spec file with a remote spec file • Example: A check of the loaded file is performed to ensure that each specified command is included only once, and that the SFE can be parsed correctly in XML Router# spec-file install slot0:spec_file.odm file tftp://system1/user1/spec_file.odm Step spec-file install [force] location:local-filename remove-entry command Example: Router# spec-file install slot0:spec_file.odm remove-entry show arp Step spec-file install [force] location:local-filename restore Removes an SFE from a spec file • A check is performed to ensure that the command SFE is present in the spec file • If the spec file does not exist, this command fails • A backup copy of the spec file is created before the SFE is removed Restores a spec file to its original contents using a backup (.bak) file • If the bak file does not exist, this command fails Example: Router# spec-file install slot0:spec_file.odm restore Validating Spec Files This section describes use of the show format command to validate a spec file The show format built-in validate form of the command is used to validate the built-in spec file The show format location:local-filename validate form of the command is used to validate a specific spec file 17 XML-PI Configuration Examples for XML-PI Restrictions Spec files must reside locally on the network device Using spec files from a remote filesystem is not supported SUMMARY STEPS enable show format [built-in | location:local-filename] [cli command | validate] DETAILED STEPS Step Command or Action Purpose enable Enables privileged EXEC mode • Enter your password if prompted Example: Router> enable Step show format [built-in | location:local-filename] [cli command | validate] Validates the built-in spec file Example: Router# show format built-in validate Configuration Examples for XML-PI This section provides the following configuration examples: • Configuring NETCONF for XML-PI: Example, page 18 • Generating show Command XML Format: Examples, page 19 • Generating show running-config XML Format: Examples, page 20 • Generating show Command XSD Format: Example, page 21 • Displaying the SFEs: Example, page 21 • Displaying Spec File Tag Hierarchy: Example, page 22 • Validating a Spec File: Example, page 23 Configuring NETCONF for XML-PI: Example The following example shows how to configure a secure login environment Cisco recommends that you define a default ODM file to be used for all requests using the format global command You can associate that file with NETCONF for all XML-formatted requests using the netconf format command If no file is specified, the built-in spec file is used for all requests See the format global and netconf format command reference pages for more information The netconf ssh configuration command enables NETCONF over SSHv2, which terminates the session layer and provides a secure connection ip domain-name cisco.com crypto key generate rsa ip ssh timeout 60 18 XML-PI Configuration Examples for XML-PI ip ssh authentication-retries ip ssh
