Chapter 2 IE 3000 Switch Cisco IOS Commands 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 | bpduguard | dhcp-rate-limit | dtp-flap | gbic-invalid | inline-power | link-flap | loopback | pagp-flap | sfp-config-mismatch} no errdisable detect cause {all | bpduguard | dhcp-rate-limit | dtp-flap | gbic-invalid | inline-power | 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 all Enable error detection for all error-disabled causes. 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 On the IE 3000 switch, this error refers to an invalid small form-factor pluggable (SFP) module. inline-power link-flap Enable error detection for inline power. 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. Command Default Detection is enabled for all causes. All causes, except for per-VLAN error disabling, are configured to shut down the entire port.
