Change MTU Size

November 26, 2019

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
