Change MTU Size

MTU means maximum transmission unit. The default value is 1500 for Ethernet, which is also the standard for the Internet. If your application or network requires a different MTU size, you can set the MTU size by running the following commands.

# Edit ifcfg-eth0
vi /etc/sysconfig/network-scripts/ifcfg-eth0
 
#Add MTU, settings:
MTU="1460"
 
# Save and close the file. Restart networking:
service network restart

# Edit ifcfg-eth0 vi /etc/sysconfig/network-scripts/ifcfg-eth0 #Add MTU, settings: MTU="1460" # Save and close the file. Restart networking: service network restart

About Me

I'm Ulysses, a Cloud Engineer at Cardinal Health based in Columbus, Ohio. I’m a certified AWS Solutions Architect. This website is my way of documenting the things I've learned about the Cloud. When off the grid, I enjoy riding my electric skateboard. I've surfed, snowboarded and played saxophone in the past. I hope you find this site helpful. It's powered by WordPress and hosted in AWS.
