Hotfix configuration example
Network requirements
The IRF fabric in this example comprises two member switches, the master and slave. The software
running on the member switches is having problems, and a hotfix is needed. The patch files
patch_xxx.bin
and
patch_lpu.bin
are saved on the TFTP server. The IRF fabric and TFTP server can reach
each other.
From the IRF fabric, use TFTP to download the patch files and then hotfix the software on the fabric.
