Managing Trunking Connections TABLE 90 F_Port masterless trunking considerations (continued) Category Description Long Distance Long distance is not allowed on F_Port trunks, which means that a Trunk Area is not allowed on long-distance ports. You cannot enable long distance on ports that have a Trunk Area assigned to them. Management Server Registered Node ID (RNID), Link Incident Record Registration (LIRR), and Query Security Attribute (QSA) ELSs are not supported on F_Port trunks. NPIV N_Port ID virtualization (NPIV) is supported on the F_Port master trunk. PID format F_Port trunking is supported only in the CORE PID format. Port mirroring Port mirroring is not supported on Trunk Area ports or on the PID of an F_Port trunk port. Port mirroring is not supported on the Brocade Encryption Switch. Port Swap When you assign a Trunk Area to a trunk group, the Trunk Area cannot be port swapped. If a port is swapped, then you cannot assign a Trunk Area to that port. Port Types Only F_Port trunk ports are allowed on a Trunk Area port. All other port types are persistently disabled. PWWN The entire Trunk Area trunk group shares the same Port WWN within the trunk group. The PWWN is the same across the entire F_Port trunk that has either 0x2f or 0x25 as the first byte of the PWWN. The Trunk Area is part of the PWWN in the format listed in Table 91. QoS QoS is supported. Routing Routing will route against the F_Port trunk master. Bandwidth information will be modified accordingly as the F_Port trunk forms. Trunk Master No more than one trunk master is allowed in a trunk group. The second trunk master will be persistently disabled with the reason "Area has been acquired". Upgrade There are no limitations on upgrading to Fabric OS 7.0.0 and later if the F_Port is present on the switch. Upgrading is not disruptive. PWWN formats for F_Port trunk ports The following table describes the PWWN formats for F_Port trunk ports. The initial 5 is the default value for an F_Port trunk port in a virtual fabric. The initial 2 is the default value for an F_Port trunk port that is not in a virtual fabric. Virtual fabric (NAA = 5) Non-virtual fabric (NAA = 2) 5n:nn:nn:nn:nn:nx:xx 25:xx:nn:nn:nn:nn:nn:nn 2F:xx:nn:nn:nn:nn:nn:nn The valid range of x:xx is 0-4095. The valid range of xx is 0-255. The valid range of xx is 0-255. Refer to Logical ports on page 278 for more information on PWWN construction. F_Port trunking in Virtual Fabrics F_Port trunking functionality performs the same in Virtual Fabrics as it does in non-Virtual Fabrics platforms except for the Brocade DCX 8510-8. Fabric OS uses a 10-bit addressing model. On the DCX 8510 platforms and X6 Directors, F_Port trunk ports dynamically receive an 8-bit area address that remains persistent. After F_Port trunking configurations are removed from a port in a logical switch, that port returns to the default 10-bit area addressing model, which supports up to 1024 F_Ports in a logical switch. NOTE DCX 8510-8 platforms have a maximum of 576 ports. Out of the 1024 10-bit address range, addresses 448-1023 are reserved for the 10-bit address space. Addresses 0-447 are reserved for assigning to NPIV/Loop ports to support 112 (448/4) NPIV/Loop ports in a logical switch with 256 devices each.
