errdisable detect cause
errdisable detect cause
Use the errdisable detect cause global configuration command on the switch stack or on a standalone
switch to enable error-disabled detection for a specific cause or all causes. Use the no form of this
command to disable the error-disabled detection feature.
errdisable detect cause {all | arp-inspection | bpduguard | dhcp-rate-limit | dtp-flap |
gbic-invalid | l2ptguard |link-flap | loopback | pagp-flap | sfp-config-mismatch}
no errdisable detect cause {all | arp-inspection | bpduguard | dhcp-rate-limit | dtp-flap |
gbic-invalid | l2ptguard |link-flap | loopback | pagp-flap | 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.
errdisable detect cause bpduguard shutdown vlan
no errdisable detect cause bpduguard shutdown vlan
Syntax Description
Note Though visible in the command-line help strings, the inline-power keyword is not supported.
Command Default Detection is enabled for all causes.
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.
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.
sfp-config-mismatch Enable error detection on an SFP configuration mismatch.
