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 | dhcp-rate-limit | dtp-flap | gbic-invalid | link-flap | loopback |

pagp-flap}

no errdisable detect cause {all | dhcp-rate-limit | dtp-flap | gbic-invalid | link-flap | pagp-flap}

Syntax Description

Command Default Detection is enabled for all causes.

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.

If you set a recovery mechanism for the cause by entering the errdisable recovery global configuration

command for the cause, the interface is brought out of the error-disabled state and allowed to retry the

operation when all causes have timed out. If you do not set a recovery mechanism, you must enter the

shutdown and then the no shutdown commands to manually recover an interface from the

error-disabled state.

all Enable error detection for all error-disabled causes.

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.

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.
