Enabling Jumbo Frame Support


Jumbo frames includes frames bigger than the standard Ethernet frame size, 1518 bytes (including Layer 2 (L2) header and FCS). Different vendors assign different frame sizes as the IEEE standard does not include jumbo frames.


When you enable the jumbo frame feature on a port, the port switches large or jumbo frames. This feature optimizes server-to-server performance. The default Maximum Transmission Unit (MTU) frame size is 1548 bytes for all Ethernet ports. The MTU size is increased to 9216 bytes when you enable the jumbo frame feature on a port.


Netvisor ONE disables jumbo frame support by default.


To enable jumbo frame support, add the jumbo parameter to the port-config-modify command:


CLI (network-admin@Leaf1) > port-config-modify jumbo


To enable jumbo frame support on trunk ports, add the jumbo parameter to the trunk-modify command:


CLI (network-admin@switch) > trunk-modify jumbo
