errdisable detect cause
errdisable detect cause
Use the errdisable detect cause global configuration command to enable error-disable detection for a
specific cause or all causes. Use the no form of this command to disable the error-disable detection
feature.
errdisable detect cause {all | arp-inspection | bpduguard | dhcp-rate-limit | dtp-flap |
gbic-invalid | inline-power |l2ptguard | link-flap | loopback | pagp-flap | security-violation
shutdown vlan | sfp-config-mismatch}
no errdisable detect cause {all | arp-inspection | bpduguard | dhcp-rate-limit | dtp-flap |
gbic-invalid | inline-power |l2ptguard | link-flap | loopback | pagp-flap | security-violation
shutdown vlan | sfp-config-mismatch}
For the BPDU guard and port-security features, you can use this command to globally configure the
switch to shut down just the offending VLAN on the port when a violation occurs, instead of shutting
down the entire port.
When the per-VLAN error-disable feature is turned off and a BPDU guard violation occurs, the entire
port is disabled. Use the no form of this command to disable the per-VLAN error-disable feature.

no errdisable detect cause bpduguard shutdown vlan
Syntax Description all Enable error detection for all error-disabled causes.
arp-inspection Enable error detection for dynamic Address Resolution Protocol (ARP)
inspection.
bpduguard shutdown vlan Enable per-VLAN error-disable for BPDU guard.
dhcp-rate-limit Enable error detection for DHCP snooping.
dtp-flap Enable error detection for the Dynamic Trunking Protocol (DTP)
flapping.
gbic-invalid Enable error detection for an invalid Gigabit Interface Converter
(GBIC) module.
Note This error refers to an invalid small form-factor pluggable (SFP)
module on the switch.
inline-power Enable error detection for inline power.
l2ptguard Enable error detection for a Layer 2 protocol tunnel error-disabled
cause.
link-flap Enable error detection for link-state flapping.
loopback Enable error detection for detected loopbacks.
pagp-flap Enable error detection for the Port Aggregation Protocol (PAgP) flap
error-disabled cause.
security-violation
shutdown vlan
Enable voice aware 802.1x security.
sfp-config-mismatch Enable error detection on an SFP configuration mismatch.
