73.4 Error-Disable Detect Setup

Figure 430 SECURITY > Errdisable > Errdisable Detect
The following table describes the labels in this screen.
Port This field displays the port number. In Stacking mode, the first number represents the slot ID and
the second is the port number. Please note that the default stacking ports (the last four ports of
your Switch) cannot be configured. They are reserved for stacking only.
* Use this row to make the setting the same for all ports. Use this row first and then make
adjustments to each port if necessary.
Changes in this row are copied to all the ports as soon as you make them.
Rate Limit (pkt/s) Enter a number from 0 to 256 to specify how many control packets this port can receive or
transmit per second.
0 means no rate limit.
You can configure the action that the Switch takes when the limit is exceeded.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
