Using the CMC Web Interface 161
Duplex Mode Set the duplex mode to full or half to match your network
environment.
Implications: If Auto Negotiation is turned On for one device
but not the other, then the device using auto negotiation can
determine the network speed of the other device, but not the
duplex mode. In this case, duplex mode defaults to the half
duplex setting during auto negotiation. such a duplex
mismatch results in a slow network connection.
NOTE: The network speed and duplex mode settings are not
available if Auto Negotiation is set to On.
MTU Sets the size of the Maximum Transmission Unit (MTU), or
the largest packet that can be passed through the interface.
Configuration range: 576 – 1500.
Default: 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.
