Port number offset
Some M-EOS switches assign PIDs with an area field (the middle byte of the PID) that has an
offset of four added to the port number. This means, for example, that the physical port
number (zero) 0 has an address value used in the PID of 4.
The port number offset is conveyed between the neighboring switches through the ESS ILS
(Exchange Security Attributes), allowing neighboring switches to accurately identify port
numbers and their associated PIDs. The maximum port number is also available in the ESS
ILS.
NPIV
NPIV management on the Fabric OS switch is the same as in the standard Fabric OS SAN that
is not merged. There are no limitations for NPIV support in an M-EOS Fabric 1.0 mode fabric.
Notes
Launch from DCFM with non fabric-wide
configuration.
Allows fabric-wide activation of zone
configurations in McDATA Fabric mode and
McDATA Open Fabric mode. No zoning
management in Fabric OS switch except
cfgClear and cfgDisable after a switch is
disabled. Regular zones cannot be configured
on Fabric OS switches.
