F_Port trunking

c. Enable the trunk on the ports by using the portTrunkArea command.
switch:admin> porttrunkarea --enable 3/40-41 -index 296
Trunk index 296 enabled for ports 3/40 and 3/41.
2. On the host side, enable trunking as described in the Brocade Adapters Administrator’s Guide.
3. On the switch side, enable the ports by using the portEnable command.
switch:admin> portenable 3/40
switch:admin> portenable 3/41
F_Port trunking considerations
Table 80 describes the F_Port masterless trunking considerations.
TABLE 80 F_Port masterless trunking considerations
Category Description
AD You cannot create a Trunk Area on ports with different Admin Domains. You cannot create a
Trunk Area in AD255.
Area assignment You statically assign the area within the trunk group on the edge switch. That group is the
F_Port trunk.
The static trunk area you assign must fall within the ASIC's trunk group of the switch or
blade starting from port 0, and must be one of the port’s default areas of the trunk group.
10-bit addressing is the default mode for all dynamically created partitions in the Brocade
DCX and DCX 8510-8 platforms.
Authentication Authentication occurs only on the F_Port trunk master port and only once per the entire
trunk. This behavior is the same as E_Port trunk master authentication. Because only one
port in the trunk does FLOGI to the switch, and authentication follows FLOGI on that port,
only that port displays the authentication details when you issue the portShow command.
NOTE: Switches in Access Gateway mode do not perform authentication.
configdownload If you issue the configDownload command for a port configuration that is not compatible
with F_Port trunking, and the port is Trunk Area-enabled, then the port will be persistently
disabled. F_Port trunks will never be restored through configDownload.
NOTE: Configurations that are not compatible with F_Port trunking are long distance, port
mirroring, non-CORE_PID, and Fast Write.
domain,index (D,I) 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: Be sure 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.
