IRF
•
Set the physical state change suppression interval to 0 on Ethernet
interfaces so their physical state changes are immediately reported to the
CPU.
•
Enable link-aggregation traffic redirection to ensure continuous traffic
service.
•
Enable the IRF bridge MAC address to be permanent.
•
To perform an incompatible upgrade for the entire IRF fabric, you must
disable IRF MAD first. Reconfigure IRF MAD after completing the
incompatible upgrade.
Determining the upgrade procedure
1.
Use
to choose an upgrade command set, depending on the ISSU method.
2.
Choose the correct procedure from the procedures described in "
Performing an ISSU by using install commands
Understanding ISSU guidelines
To use the reboot upgrade method for an IRF fabric that has IRF physical interfaces on MPUs, make
sure all MPUs have IRF physical links.
During an ISSU, use the following guidelines:
•
Verify that the device has sufficient hardware resources.
•
In a multiuser environment, make sure no other administrators access the device while you are
performing the ISSU.
•
Do not perform any of the following tasks during an ISSU:
Reboot, add, or remove cards.
Execute commands that are irrelevant to the ISSU.
Modify, delete, or rename image files.
•
You cannot use both
install
and
issu
commands for an ISSU. However, you can use
display
issu
commands with both command sets. For more information, see "
•
You do not need to upgrade LPUs or switching fabric modules separately. They are upgraded
automatically when MPUs are upgraded.
•
You only need to perform the upgrade on the default MDC. The system completes software
upgrade for all the other MDCs automatically.
•
Before executing the following commands, use the
display system stable state
command to
verify that the system is stable:
issu commands
—
issu load
,
issu run switchover
, and
issu commit
.
install commands
—
install activate
and
install deactivate
.
If the
System State
field displays
Stable
, the system is stable.
•
You may use
issu
commands to upgrade all or some of the software images. If you are
upgrading only some of the images, make sure the new images are compatible with the images
that are not to be upgraded. The upgrade will fail if a conflict exists.
After an ISSU, you must log in to the device again before you can configure the device.
