Fabric OS 6.1.x administrator guide 379
Table 82 describes the PWWN format for F_Port and N_Port trunk ports.
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
Figure 49. 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 based on the
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.
Note: “I” refers to Index and D,I refers to Domain,Index.
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 is not supported in the same F_Port trunk group.
QoS Not currently supported.
