Configuring Ports
CLI Command To configure ports on a Fast Ethernet module using the CLI, enter the
following command from Configure mode:
(configure)# set port
Auto Negotiation
Duplex
Advertisement Determines what information the port advertises when it
starts auto-negotiating. In most cases, Half/Full are the
best settings, but there may be cases when you want to
auto-negotiate one parameter, while keeping the other
fixed.
Flood Rate Limit
Mode Prevents the switch from overwhelming the output buffer
on lower-speed ports by placing a threshold on the
percentage of port traffic that can be flooded packets
(unknown unicasts and multicasts).
You can also optionally include known multicast packets
in this percentage to further decrease the possibility of
the port’s output buffer that is being overwhelmed.
Flood Rate Limit
Rate Determines the percentage of a port’s forwarded traffic
that can be unknown unicast and multicast (flooded).
Lower this value if the port has overflow problems.
Flood Rate Limit
Burst Size Enter a value for the limit of packets allowed in a single
burst. Accepted values are 1 to 2048. For Fast Ethernet
ports, set this value lower than 1024 (output buffer
capacity). Lower this value if the port has overflow
problems.
Port PACE
Priority Select Enable to allow the port to detect 3Com’s
proprietary PACE format as packets pass through the
port. PACE allows a packet’s priority (higher priority
packets move through the switch before lower priority
packets) to be set at the adapter.
