Error Disable Recovery
The error disable auto-recovery mechanism
is used to bring the ports out of the error-disabled state. You can use the
speed-duplex command to change
the configured speed of the member ports, which will result in an operational speed
change
implicitly. Depending on the peer speed duplex setting, either the port will come
up in a
negotiated operational speed or the port will remain down if the speed does not
match the
peer speed configuration. Using the speed-duplex command on VLAG
interfaces flaps the LAG member ports; all member ports that come up will subsequently
have
the same operational speed.As different port types are bundled, their port speed capabilities, such as maximum
speed and range of speeds supported, are not the same. Therefore, you can use the
speed-duplex command only if all member ports can support the given speed value. If the configured
speed cannot be supported on at least one member port, the
speed-duplex command is rejected with an appropriate error message.
An interface that is error-disabled for LAG operational speed mismatch can be recovered in the following ways:
- Temporarily disable and re-enable the LAG interface using the
shutdownandno shutdowncommands, respectively, in LAG interface configuration mode. - Temporarily disable and re-enable the specific errdisabled interface port using the
shutdownandno shutdowncommands, respectively, in port interface mode for the specific LAG configuration. - Remove the error-disabled interface from the LAG (using
the
no ports ethernetcommand in LAG configuration mode) to reset the error-disabled state.
