errdisable detect cause
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 | dtp-flap | gbic-invalid | l2ptguard| link-flap | loopback | pagp-flap}
no errdisable detect cause {all | dtp-flap | gbic-invalid | l2ptguard | link-flap | loopback |
pagp-flap}
Syntax Description
Note Though visible in the command-line help strings, the dhcp-rate-limit keyword is not supported.
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 (dtp-flap, gbic-invalid, l2ptguard, link-flap, loopback, and pagp-flap) 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 link-down state.
When a port is error-disabled, it is effectively shut down, and no traffic is sent or received on the port.
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.
dtp-flap Enable error detection for the Dynamic Trunking Protocol (DTP) flapping.
gbic-invalid Enable error detection for an invalid GBIC. This error refers to an invalid small
form-factor pluggable (SFP) module interface cause.
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.
