same security levels on 2 interfaces on ASA 7.x

If i have 2 interfaces with the same security level on ASA running 7.x code, with " same-security-traffic permit inter-interface " enabled and also an acl in place on both those interfaces, will the implicit permit be still effective between the same security level interfaces or will the acl take effect ?

thanks,

Vikram

no it will not, the command will bypass ACLs, in other words acl has not precedence over the command.

Vikram, one of the purposes of same-security-traffic permit inter-interface command is to allow communications between interfaces with same interface security level without the use of access lists, so if this is what you are trying to accomplish then any permit rules between these same security interfaces can technically be decomissioned as this command will permit traffic between the two.

Re: same security levels on 2 interfaces on ASA 7.x

this answers part of the question, but what if i have "same-security-traffic permit inter-interface" and access-list configured on the interfaces with same security-level,

Question: will this make "same-security-traffic permit inter-interfae" command ineffective ??

thanks,
