F_Port masterless trunking 19 TABLE 85 F_Port masterless trunking considerations (Continued) Category Description Routing 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. NPIV Supported on F_Port master trunk. Two masters Two masters are not supported in the same F_Port trunk group. QoS Not currently supported. 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 behaves 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. Note: "I" refers to Index and D,I refers to Domain,Index. Assigning a Trunk Area Ports from different ADs are not allowed to join the same Trunk Area group. The portTrunkArea command prevents the different ADs from joining the TA group. When you assign a TA, the ports within the TA group have the same Index. The Index that was assigned to the ports is no longer part of the switch. Any Domain,Index (D,I) AD that was assumed to be part of the domain may no longer exist for that domain because it was removed from the switch. Example: How Trunk Area assignment affect the port Domain,Index If you have AD1: 3,7; 3,8; 4,13; 4,14 and AD2: 3,9; 3,10, and then create a TA with Index 8 with ports that have index 7, 8, 9, and 10, then index 7, 9, and 10 are no longer with domain 3. This means that AD2 does not have access to any ports because index 9 and 10 no longer exist on domain 3. This also means that AD1 no longer has 3,7in effect because Index 7 no longer exists for domain 3. AD1's 3,8, which is the TA group, can still be seen by AD1 along with 4,13 and 4,14. A port within a TA can be removed, but this adds the Index back to the switch. For example, the same AD1 and AD2 with TA 8 holds true. If you remove port 7 from the TA, it adds Index 7 back to the switch. That means AD1's 3,7 can be seen by AD1 along with 3,8; 4,13 and 4,14. When you assign an area within a trunk group, that group is F_Port masterless trunking enabled. The TA that you assign must be within the 8-port trunk group beginning with port 0 (zero). After you assign a TA to a port, the port immediately acquires the TA as the area of its PID. Likewise, after you remove a TA from a port, the port immediately acquires the default area as its PID. F_Port trunking prevents reassignments of the Port ID also referred to as the Address Identifier. Table 86 shows an example of an Address Identifier. Fabric OS Administrator's Guide 441 53-1001336-01
