errdisable detect
errdisable detect
To enable error-disable detection, use the errdisable detect command. To disable the error-disable
detection feature, use the no form of this command.
errdisable detect cause {all | arp-inspection [action shutdown vlan] | bpduguard shutdown
vlan | dhcp-rate-limit [action shutdown vlan] | dtp-flap | gbic-invalid | l2ptguard | link-flap
| pagp-flap}
no errdisable detect cause {all | arp-inspection [action shutdown vlan] | bpduguard shutdown
vlan | dhcp-rate-limit [action shutdown vlan] | dtp-flap | gbic-invalid | l2ptguard | link-flap
| pagp-flap}
Syntax Description
Defaults All error-disable causes are detected.
Command Modes Global configuration mode
Command History
Usage Guidelines A cause (dtp-flap, link-flap, pagp-flap) is defined as the reason why the error-disabled state occurred.
When a cause is detected on an interface, the interface is placed in error-disabled state (an operational
state that is similar to link-down state).
You must enter the shutdown command and then the no shutdown command to recover an interface
manually from the error-disable state.
cause Specifies error-disable detection to detect a specific cause.
all Specifies error-disable detection for all error-disable causes.
arp-inspection Specifies the detection for the ARP inspection error-disable cause.
action shutdown vlan (Optional) Specifies per-VLAN error-disable for ARP inspection and DHCP
rate limiting.
bpduguard shutdown
vlan
Specifies per-VLAN error-disable for BPDU guard.
dhcp-rate-limit Specifies the detection for the DHCP rate-limit error-disable cause.
dtp-flap Specifies the detection for the DTP flap error-disable cause.
gbic-invalid Specifies the detection for the GBIC invalid error-disable cause.
l2ptguard
Specifies the detection for the Layer 2 protocol-tunnel error-disable cause.
link-flap Specifies the detection for the link flap error-disable cause.
pagp-flap Specifies the detection for the PAgP flap error-disable cause.
