142 Using the CMC Web Interface
Network Speed Set the network speed to 100 Mbps or 10 Mbps to match
your network environment.
NOTE: The Network Speed setting must match your network
configuration for effective network throughput. Setting the
Network Speed lower than the speed of your network
configuration increases bandwidth consumption and slows
network communication. Determine whether your network
supports the above network speeds and set it accordingly.
If your network configuration does not match any of these
values, it is recommended that you use Auto Negotiation or
refer to your network equipment manufacturer.
NOTE: To use 1000 Mb or 1 Gb speeds, select Auto
Negotiation.
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 will result 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 will use an MTU of 1280.
