FastIron# switch-over-active-role
Once you enter this command, the system will prompt you as follows:
Are you sure? (enter ’y’ or ’n’): y
Running Config data has been changed. Do you want to continue
the switch-over without saving the running config? (enter ’y’ or ’n’): n
Please save the running config and try switch-over again
Syntax:
switch-over-active role
Rebooting the Active and Standby Management Modules
You can use the
boot system
or
reload
commands to reboot the management modules, maintaining the currently
configured active management module (the management module to which the
set-active-mgmt
command
applies).
For example, to reboot the active and standby management modules from the primary IronWare image in the
management module’s flash memory, enter the following
command at the Privileged EXEC level:
FastIron# boot system flash primary
Syntax:
boot system bootp | [flash primary | flash secondary] | slot | tftp <ip-address> <filename>
The
flash primary
keyword specifies the primary IronWare image in the management module’s flash memory,
while the
flash secondary
keyword specifies the secondary IronWare image in the flash memory.
The
tftp
keyword directs the switch to boot from an IronWare image on a TFTP server located at <ip-address>
with the specified <filename>.
NOTE:
To reboot the device from a TFTP server through a
fiber
connection, use the CLI command
boot system
tftp <ip-address> <filename> fiber-port
.
For example, to reboot the active and standby management modules, enter the following command at the
Privileged EXEC level:
FastIron# reload
Syntax:
reload
Hitless Management Support
This section discusses the following Hitless management features supported in software release FSX 05.0.00 and
higher:
•
Layer 2 Hitless Switchover – A CLI-driven switchover of the active and standby management modules without
interruption to switched traffic.
•
Layer 2 Hitless Operating System (OS) Upgrade – An operating system upgrade to software release FSX
05.0.00 or higher, without interruption to switched traffic.
What Happens During a Hitless OS Upgrade and Hitless Switchover
The following describes the internal events that occur during a Layer 2 hitless OS upgrade and hitless switchover:
1.
The standby management module resets and reloads with the new software image in its flash memory.
2.
The Ethernet interfaces (if present) on the standby module become operational and start carrying data traffic.
3.
The active management module synchronizes the standby management module with all the information
required to take over the active role.
4.
The Layer 2 control protocols on the standby management module converge. This process takes
approximately 70 seconds.
