Question

If an administrator issues the errordisable detect cause inline-power command on a Cisco switch and a PD attempts to draw more than the cutoff power, how long will the interface remain in an error-disabled state?

a) 300 seconds
b) Until manually reset with the shutdown and no shutdown commands
c) 30 seconds
d) 86400 seconds

Answer 1

Option (B), The interface on a Cisco switch will remain in an error-disabled state until manually reset with the shutdown and no shutdown commands after a PD tries to draw more power than allowed.

Step-by-step explanation:

When an administrator issues the errordisable detect cause inline-power command on a Cisco switch, and a Powered Device (PD) tries to draw more power than the cutoff allows, the interface will go into an error-disabled state. The interface will remain in this state until it is manually reset. This reset is accomplished by issuing the shutdown and no shutdown commands on the affected interface. There is no automatic recovery from an error-disabled state due to inline power overdraw unless auto-recovery has been specifically configured.
