changing network interface MTU value in Vmware agent appliance

Thread needs solution

Hi, We have a dedicated storage network for backup with jumbo frame (MTU 9000) enabled and we deployed VMware agent appliance. How can I change the MTU on the appliance so that it can use jumbo frame for backup, please?

regards,

Aldous

Hi! 

Thank you for your posting! To set the MTU value follow the below steps: 

1) connect via WinSCP (instructions can be found here in the "Troubleshooting steps" section: https://kb.acronis.com/content/36100
2) look for the file  "/ bin / autostart" and open it in Notepad
3) then find the line  echo "$ procs"  and in the next line add  "ifconfig eth0 mtu 9000 up"
4) save the file and reboot the appliance

Let me know if that helped.

After I added the line 'ifconfig eth1 mtu 9000 up' (i used eth1 because I have two NIC and eth1 is the one I want to have mtu 9000) and rebooted, I got error "Network interface cards cannot be found". However, when I check the MTU setting, it was showing 9000 (See attached, bootup error, the ip a output and autostart file)

Hi! 

Sorry for the delayed response! Took some time to run tests

Try to put the line "ifconfig eth1 mtu 9000" at the end of the autostart file, then reboot and check if this works.
