Access Gateway N_Port trunking
2
The following table describes the PWWN format for F_Port and N_Port trunk ports.
Trunk group creation
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. The Brocade 300 switch supports a trunk group with up to eight ports.
The trunking groups are based on the user port number, with contiguous eight ports as one group,
such as 0 – 7, 8- 15, 16-23 and up to the number of ports on the switch.
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.
Two masters Two masters is not supported in the same F_Port trunk group.
QoS Not currently supported..
