Setting the Maximum Transmission Unit (MTU) (IPv4 and IPv6)

The MTU property allows you to set a limit for the largest packet that can be passed through the interface. To set the
MTU, type:
racadm config -g cfgNetTuning -o cfgNetTuningMtu <mtu>
where <mtu> is a value between 576–1500 (inclusive; default is 1500).
NOTE: IPv6 requires a minimum MTU of 1280. If IPv6 is enabled, and cfgNetTuningMtu is set to a lower value,
the CMC uses an MTU of 1280.

Configuring Virtual LAN Tag Properties for CMC

VLANs are used to allow multiple virtual LANs to co-exist on the same physical network cable and to segregate the
network traffic for security or load management purposes. When you enable the VLAN functionality, each network
packet is assigned a VLAN tag.
