FWSM DHCP-relay configuration triggered a failover !

Hi,

I have two FWSM in multiple contexts mode and working as active/standby.


I configured DHCP relay on one context interface (DMZ), using the ASDM graphical interface. When applying the configuration, a failover occured, which led to loss of connectivity between inside and outside for about 20 seconds.


Is it normal that the activation of the DHCP relay function is disruptive ?


More generally, is there an existing list of commands that are not transparently applied in a FWSM ?


Thank you for any comments


Yves

1)You cannot enable a DHCP relay agent on an interface that has a DHCP relay server configured for it.


2)The DHCP relay agent works only with external DHCP servers; it will not forward DHCP requests to a FWSM interface configured as a DHCP server.


Before you can enable a DHCP relay agent on an interface, you must have at least one DHCP relay global server or DHCP relay interface server in the configuration.
