Changes in Switch Behavior When Interoperability Is Enabled (continued)
Changes if Interoperability Is Enabled
TE ports and PortChannels cannot be used to connect Cisco MDS to non-Cisco
MDS switches. Only E ports can be used to connect to non-Cisco MDS
switches. TE ports and PortChannels can still be used to connect an Cisco MDS
to other Cisco MDS switches even when in interop mode.
The routing of frames within the fabric is not changed by the introduction of
interop mode. The switch continues to use src-id, dst-id, and ox-id to load
balance across multiple ISL links.
This is a switch-wide impacting event. Brocade and McData require the entire
switch to be placed in offline mode and/or rebooted when changing domain
IDs.
This event is limited to the affected VSAN. Only Cisco MDS 9000 Family
switches have this capability—only the domain manager process for the
affected VSAN is restarted and not the entire switch.
Verify that all vendors have the correct values in their respective name server
database.
IVR-enabled VSANs can be configured in no interop (default) mode or in any
of the interop modes.
