errdisable detect cause
Use the errdisable detect cause global configuration command 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 | dhcp-rate-limit | gbic-invalid | l2ptguard |
link-flap | loopback | pagp-flap | small-frame}
no errdisable detect cause {all | arp-inspection | dhcp-rate-limit | gbic-invalid | l2ptguard |
link-flap | pagp-flap | small-frame}
Note
Syntax Description
Defaults Detection is enabled for all causes. All causes, except for per-VLAN error disabling, are configured to
shut down the entire port.
Command Modes Global configuration
Command History
Usage Guidelines A cause (all, dhcp-rate-limit, and so forth) is the reason why the error-disabled state occurred. When a
cause is detected on an interface, the interface is placed in an error-disabled state, an operational state
that is similar to a link-down state.
all Enable error detection for all error-disable causes.
arp-inspection Enable error detection for dynamic Address Resolution Protocol (ARP)
inspection.
dhcp-rate-limit Enable error detection for DHCP snooping.
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.
small-frame See the errdisable detect cause small-frame command.
