◆
The rate limits set by this command are also used by automatic storm
control when the control response is set to rate limiting by the auto-
traffic-control action command.
◆
Using both rate limiting and storm control on the same interface may
lead to unexpected results. For example, suppose broadcast storm
control is set to 500 Kbps by the command “switchport broadcast
packet-rate 500,” and the rate limit is set to 20000 Kbps by the
command “rate-limit input 20000" on a Fast Ethernet port. Since 20000
Kbps is 1/5 of line speed (100 Mbps), the received rate will actually be
100 Kbps, or 1/5 of the 500 Kbps limit set by the storm control
command. It is therefore not advisable to use both of these commands
on the same interface.

The following shows how to configure broadcast storm control at 600
kilobits per second:
Console(config)#interface ethernet 1/5
Console(config-if)#switchport broadcast packet-rate 600
Console(config-if)#
transceiver-
threshold current
This command sends a trap when the transceiver current falls outside the
specified thresholds.

transceiver-threshold current { high-alarm | high-warning | low-
alarm | low-warning } threshold-value
high-alarm – Sends an alarm message when the high current
threshold is crossed.
high-warning – Sends a warning message when the high current
threshold is crossed.
low-alarm – Sends an alarm message when the low current
threshold is crossed.
low-warning – Sends a warning message when the low current
threshold is crossed.
threshold-value – The threshold of the transceiver current.
