SET SWITCH BROADCAST
Syntax
set switch broadcast timer10_100mbps=integer
timer1000mbps=integer
Parameters
timer10_100mbps Specifies the broadcast timer interval for ports
operating at 10 Mbps or 100 Mbps. The range is 10
to 120 milliseconds, in increments of 10, with a
default of 10 milliseconds.
timer1000mbps Specifies the length of time, in microseconds, for
ports operating at 1000 Mbps. The range is 100 to
12,000 microseconds, in increments of 100, with a
default of 100 microseconds.
Description
This command specifies the broadcast interval timer which defines the
time period used in counting the number of forwarded egress broadcast
frames on a port. There are two interval timers. One timer is for ports
operating at 10 Mbps and 100 Mbps. The second timer is for 1000 Mbps
ports. The timer interval for 10 and 100 Mbps ports is measured in
milliseconds. The timer interval for 1000 Mbps ports is measured in
microseconds. A time interval setting applies to all ports operating at the
corresponding speed on the switch.
Note
The 1000 Mbps speed applies only to optional Gigabit Ethernet
ports.
Both timers round down your input. For the timer interval for 10 and 100
Mbps ports, values you enter are rounded down to the nearest multiple
of 10. For the 1000 Mbps timer, values you enter are rounded down to
the nearest multiple of 100 microseconds.
To set the maximum number of broadcast frames a port will transmit,
refer to the SET SWITCH PORT BCLIMIT command.
Examples
The following command sets a broadcast timer of 500 milliseconds for
ports operating at 10 Mbps or 100 Mbps:
set switch broadcast timer10_100mbps=500
