Poap Configuration Script; Guidelines And Limitations For Poap Configuration; Using Poweron Auto Provisioning - Cisco MDS 9000 Series Configuration Manual

About Power On Auto Provisioning
DHCP information is used during the POAP process only when POAP fails via USB because of the
Note
following reasons:
• USB is not present.
• Script is not present or script is present with incorrect names.
• Script execution fails.

POAP Configuration Script

The reference script supplied by Cisco supports the following functionalities:
• Retrieves switch-specific identifiers, for example, the serial number.
• Downloads the software images (system and kickstart images) if the files do not already exist on the
switch.
• Installs the software image on the switch, which is then used at the next reboot.
• Schedules the downloaded configuration to be applied at the next switch reboot.
• Stores the configuration as startup configuration.

Guidelines and Limitations for POAP Configuration

The POAP configuration guidelines and limitations are as follows:
• Only FAT32 USB is supported. (The file system on the USB should be FAT32). For both Cisco MDS
9700 and 9500 series switches, POAP is supported only on USB 1 Port.
• The software image for the Cisco MDS 9000 Series Switches, including the Cisco MDS 9396S Multilayer
Fabric Switch, must support POAP.
POAP via USB is supported from Cisco MDS NX-OS Release 7.3(0)D1(1).
• POAP can be initiated on any switch by erasing the startup configuration and reloading the switch.
• POAP does not support provisioning of the switch after it has been configured and is operational. Only
auto provisioning of a switch with no startup configuration is supported.
• Important POAP updates are logged in the syslog and are available from the serial console.
• Critical POAP errors are logged to the bootflash. The filename format is
date-time_poap_PID_[init,1,2].log, where date-time is in the YYYYMMDD_hhmmss format and PID
is the process ID.
• Script logs are saved in the bootflash directory. The filename format is date-time_poap_PID_script.log,
where date-time is in the YYYYMMDD_hhmmss format and PID is the process ID.
• You can configure the format of the script log file. These formats are specified in the script. The template
of the script log file has a default format. However, you can choose a different format for the script
execution log file.
