errdisable recovery
errdisable recovery
Use the errdisable recovery global configuration command to configure the recover mechanism
variables. Use the no form of this command to return to the default setting.
errdisable recovery {cause {all | bpduguard | channel-misconfig | dhcp-rate-limit | dtp-flap |
gbic-invalid | link-flap | loopback | pagp-flap | psecure-violation | security-violation | udld
| vmps}} | {interval interval}
no errdisable recovery {cause {all | bpduguard | channel-misconfig | dhcp-rate-limit | dtp-flap
| gbic-invalid | link-flap | loopback | pagp-flap | psecure-violation | security-violation | udld
| vmps}} | {interval interval}
Syntax Description
Note Though visible in the command-line help string, the unicast-flood keyword is not supported.
cause Enable error disable to recover from a specific cause.
all Enable the timer to recover from all error-disable causes.
bpduguard Enable the timer to recover from the bridge protocol data unit
(BPDU)-guard error-disable state.
channel-misconfig Enable the timer to recover from the EtherChannel misconfiguration
error-disable state.
dhcp-rate-limit Enable the timer to recover from the DHCP error-disable state.
dtp-flap Enable the timer to recover from the Dynamic Trunking Protocol (DTP)-flap
error-disable state.
gbic-invalid Enable the timer to recover from an invalid GBIC error disable state.
link-flap Enable the timer to recover from the link-flap error-disable state.
loopback Enable the timer to recover from the loopback error-disable state.
pagp-flap Enable the timer to recover from the Port Aggregation Protocol (PAgP)-flap
error-disable state.
psecure-violation Enable the timer to recover from a port security violation disable state.
security-violation Enable the timer to recover from an IEEE 802.1x violation disable state.
udld Enable the timer to recover from the UniDirectional Link Detection
(UDLD) error-disable state.
vmps Enable the timer to recover from a VLAN Membership Policy Server
(VMPS) error-disable state.
interval interval Specify the time to recover from specified error-disable state. The range is
30 to 86400 seconds. The same interval is applied to all causes. The default
interval is 300 seconds.
Note The errdisable recovery timer initializes at a random differential
from the configured interval value. The difference between the
actual timeout value and the configured value can be up to
15 percent of the configured interval.
