Table 82 F_Port masterless trunking considerations Category Description DCC Policy DCC policy enforcement for the F_Port trunk is based on the Trunk Area; the FDISC requests to a trunk port is accepted only if the WWN of the attached device is part of the DCC policy against the TA. The PWWN of the FLOGI sent from the AG will be dynamic for the F_Port trunk master. Because you do not know ahead of time what PWWN AG will use, the PWWN of the FLOGI will not go through DCC policy check on an F_Port trunk master. However, the PWWN of the FDISC will continue to go through DCC policy check. D.I. Zoning (D,I) AD (D, I) DCC and (PWWN, I) DCC Creating a Trunk Area may remove the Index ("I") from the switch to be grouped to the Trunk Area. All ports in a Trunk Area share the same "I". This means that Domain,Index (D,I), which refer to an "I", that might have been removed, will no longer be part of the switch. Note: Ensure to include AD, zoning and DCC when creating a Trunk Area. You can remove the port from the Trunk Area to have the "I" back into effect. D,I will behave as normal, but you may see the effects of grouping ports into a single "I". Also, D,I continues to work for Trunk Area groups. The "I" can be used in D,I if the "I" was the "I" for the Trunk Area group. Routing NPIV Two masters QoS Note: "I" refers to Index and D,I refers to Domain,Index. Routing will route against the F_Port trunk master. Port and exchange-based routing is supported on the F_Port trunk masters. Bandwidth information will be modified accordingly as the F_Port trunk forms. Supported on F_Port master trunk. Two masters is not supported in the same F_Port trunk group. Not currently supported. Table 83 PWWN format for F_Port and N_Port trunk ports NAA = 2 2f:xx:nn:nn:nn:nn:nn:nn (1) Port WWNs for: switch's Fx_Ports. NAA = 2 25:xx:nn:nn:nn:nn:nn:nn (1) Port WWNs for: switch's Fx_Ports The valid range of xx is [0 FF], for maximum of 256. The valid range of xx is [0 FF], for maximum of 256. Setting up F_Port trunking F_Port trunking is enabled between two separate Fabric OS switches that support trunking and where all the ports on each switch reside in the same quad and are running the same speed. Trunk groups form when you connect two or more cables on one Fabric OS switch to another Fabric OS switch with ports in the same port group or quad. A port group or a quad is a set of sequential ports, for example ports 0-3 in the figure shown below. The HP StorageWorks 8/8 SAN Switch, 8/24 SAN Switch, 8/40 SAN Switch and the 8/80 SAN Switch platforms support a trunk group with up to eight ports. The trunking groups are Fabric OS 6.1.x administrator guide 369
