Adding a New Boot Stack Entry

Important
If priority 1 is in use, then you must renumber the existing entry(ies) to ensure that at least that priority is
available. The maximum number of boot stack entries that can be contained in the boot.sys file is 10. If there
are already 10 entries in the boot stack, you must delete at least one of these entries (typically, the lowest
priority) and, if necessary, renumber some or all of the other entries before proceeding. Refer to
Boot Stack Entry, on page 127
This procedure details how to add new boot stack entries to the boot.sys file. Make sure you are at the Exec
mode prompt and enter the following commands:
configure
boot system priority number image image_url config cfg_url
The following command creates a new boot stack entry, using a boot priority of 3.
boot system priority 3 image /flash/image_filename.bin config /flash/config_name.cfg
Important
Synchronize the local file systems on the MIO/UMIO/MIO2s with the following command:
filesystem synchronize all
Deleting a Boot Stack Entry
This procedure details how to remove an individual boot stack entry from the boot.sys file. Make sure you
are at the Exec mode prompt and enter the following commands:
configure
no boot system priority number
Where number specifies the boot priority used for the boot stack entry. This command removes that specific
entry from the boot stack, causing the boot.sys file to be overwritten.
Network Booting Configuration Requirements
Configuring the Boot Interface
Boot interface parameters define the MIO/UMIO/MIO2 management LAN interface that the system will use
to communicate with the management network when using the network booting method.
Before performing this procedure, verify that there are less than 10 entries in the boot.sys file and that a
higher priority entry is available (i.e. that minimally there is no priority 1 entry in the boot stack). Refer
to Viewing the Current Boot Stack for more information.
for more information.
Boot stack changes saved to the boot.sys file are not executed until the system is rebooted.
