Enabling version compatibility check 

Before performing an ISSU upgrade, you need to check the version compatibility between the new and 

current system software images, to determine whether ISSU can be performed, and which ISSU method 

is adopted. 
After downloading and saving the new system software image, select an ISSU upgrade method 

according to one of the following version compatibility check results: 

•

 

Compatible

—

The running system software image is compatible with the new system software 

image. You can use the compatible ISSU method to upgrade system software of the IRF fabric. For 

more information, see ”

Configuring compatible ISSU

.” 

•

 

Incompatible

—

The current running system software image is incompatible with the new system 

software image. You can use the incompatible ISSU method to upgrade system software of the IRF 
fabric. For more information, see ”

Configuring incompatible ISSU

.” 

•

 

Unknown

—

The current and new system software images have big differences, or the current system 

software image does not support ISSU. You cannot upgrade system software through ISSU. 

Follow these steps to enable version compatibility check: 

To do… 

Use the command…

system software image, perform a compatible ISSU by following 

Table 13

. 

 

 

CAUTION: 

Before performing compatible ISSU, make sure that the priorities of the current master switch and the 
specified slave switch are higher than other IRF member switches so that the specified slave switch can be

elected as the new master after the master is rebooted. Otherwise, modify the priorities of the current 

master switch and the specified slave switch with the
