M-EOS feature limitations in mixed fabrics
The following features have inherent limitations:
• 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
Open E_Port Yes Autonegotiates the R_RDY mode by
default. Uses portCfgIsMode to
static configure the port.
Port mirroring Yes Fabric OS v6.2.0 and later supports
8 Gbps port mirroring.
SNMP Yes
Speed negotiation Yes
syslog daemon Yes
QoS No

• Frame-level ISL Trunking from Fabric OS to
Fabric OS: Yes; McDATA Fabric mode only
• Frame-level ISL Trunking from Fabric OS to
M-EOS: No
• Load balancing from Fabric OS to Fabric
OS using DLS or DPS: Yes
• Load balancing from Fabric OS to M-EOS
