Hello Maciej: The ports numbers from 0 to 1023 are having specific roles. Ex: 80 for HTTTP, 443 for HTTPS. In the case can we set Min as 1024 and Max as 65535. Thanks Siva From: devel@edk2.groups.io [mailto:devel@edk2.groups.io] On Behalf Of Maciej Rabeda Sent: Tuesday, September 1, 2020 7:32 PM To: devel@edk2.groups.io; Sivaraman Nainar Subject: Re: [edk2-devel] TCP Port for ISCSI Connection Hi Siva, What seems to be the problem at hand? What kind of range of values for TargetPort do you propose? TARGET_PORT_MIN/MAX_NUM refer to a range of values (0-65535) that be set in TargetPort field in iSCSI HII. 3260 is a default TCP port for iSCSI. I see nothing wrong with that.

Which can be set from 0 to 65535 As per below RFC it talks about the Default Port only. Still it not clearly said if we can use the numbers 49152-65535 which is reserved. https://tools.ietf.org/html/rfc3720 13. IANA Considerations This section conforms to [RFC2434]. The well-known user TCP port number for iSCSI connections assigned by IANA is 3260 and this is the default iSCSI port. Implementations needing a system TCP port number may use port 860, the port assigned by IANA as the iSCSI system port; however in order to use port 860, it MUST be explicitly specified - implementations MUST NOT default to use of port 860, as 3260 is the only allowed default. with my understanding, it wouid be good if we can change the below Min and MAX port number ranges with right ranges. #define TARGET_PORT_MIN_NUM 0 #define TARGET_PORT_MAX_NUM 65535 Thanks Siva This e-mail is intended for the use of the addressee only and may contain privileged, confidential, or proprietary information that is exempt from disclosure under law.
