CHAPTER 29
Error Disable
29.1 Error Disable Overview
This chapter shows you how to configure the rate limit for control packets on a port, and set the
Switch to take an action (such as to shut down a port or stop sending packets) on a port when the
Switch detects a pre-configured error. It also shows you how to configure the Switch to
automatically undo the action after the error is gone.

control packets (ARP, BPDU and/or IGMP) that the Switch can receive or transmit on a port.
•Use the Errdisable Detect screen (Section 29.5 on page 230) to have the Switch detect
whether the control packets exceed the rate limit configured for a port and configure the action
to take once the limit is exceeded.
•Use the Errdisable Recovery screen (Section 29.6 on page 231) to set the Switch to
automatically undo an action after the error is gone.
