What happens to FlexAddress if I need to reset my chassis configuration using the RACADM command, racresetcfg?

The FlexAddress feature will still be activated and ready to use. All fabrics and slots are selected as default.

NOTE: It is highly recommended that you turn off your chassis before running the RACADM command racresetcfg.

After disabling only the FlexAddressPlus feature (leaving FlexAddress still activated), why does the racadm setflexaddr command on the (stillactive) CMC fail?

If the CMC subsequently becomes active, with the FlexAddressPlus feature card still in the card slot, the FlexAddressPlus feature gets reactivated, and slot or fabric flexaddress configuration changes can resume.

After a configuration change, sometimes CMC displays the IP address as 0.0.0.0.

Click the Refresh icon to see if the IP address is set correctly on the switch. If an error is made in setting the IP/mask/gateway, the switch does not set the IP address and returns a 0.0.0.0 in all fields.

Common errors are:

Setting the out-of-band IP address to be the same as, or on the same network as, the in-band management IP address.

Entering an invalid subnet mask.

Setting the default gateway to an address that is not on a network, which is directly connected to the switch.
