Ethernet Port Configuration Commands 55
Description
■ Use the mdi command to configure the network cable type for an Ethernet
port.
■ Use the undo mdi command to restore the default type. By default, the
network cable type is recognized automatically (the
mdi auto command).
Note that this command only has effect on 10/100BASE-T and
10/100/1000BASE-T ports. The Switch 4500 only supports
auto (auto-sensing). If
you enter another type, an error message displays.
Example
To configure the network cable type of port “Ethernet1/0/1” as cross-over cable,
enter the following:

multicast-suppression Syntax
multicast-suppression { ratio | pps pps}
undo multicast-suppression
View

Parameter
ratio: Specifies the bandwidth ratio of multicast traffic allowed on an Ethernet
port. The ratio value ranges from 1 to 100. The incremental step is 1. By default,
the ratio is 100 meaning all multicast traffic is accepted. The smaller the ratio is,
the less bandwidth is allocated to multicast traffic and therefore less broadcast
traffic is accepted on the Ethernet port.
pps pps: Specifies the maximum number of multicast packets per second accepted
on an Ethernet port. Ranges from 1 to 148810 pps.
Description
Use multicast-suppression to configure the amount of multicast traffic that will
be accepted on a port. Once the multicast traffic exceeds the value set by the user,
the excess multicast traffic will be discarded. This feature can be used to ensure
network service and prevent multicast storms.
Example
Enable a limit of 20% of the available bandwidth on a port to be allocated to
multicast traffic. Multicast traffic exceeding 20% of the ports bandwidth will be
discarded.
