Interoperability mode behavior summary by switch type
This section provides information about interoperability mode behavior the switches.
C-series
The MDS series of switches are limited in the following areas when interoperating with non-MDS
switches:
•
Interop mode only affects the specified VSAN. The MDS-9000 can operate with full functionality
in other non-interop mode VSANS. All switches that partake in the interoperable VSAN, should
have that VSAN set to interop mode, even if they do not have any end devices.
•
Domain IDs are restricted to the range of 97–127. This is to accommodate nominal restriction by
some vendors. They can either be setup statically, or preferred.
•
TE ports and Port-channels cannot be used to connect MDS to non-MDS switches. Only E_Ports
can be used to connect to non-MDS switches. However, TE ports and Port-Channels can still be
used to connect an MDS to other MDS switches even when in interop mode.
•
Only the active zoneset is distributed to other switches.
•
The default zone behavior changes with the enabling of interop mode. The default zone policy
becomes deny.
•
Modifying timers require all VSANS across the switch to be put into the suspended state.

Only VSANs explicitly set for interop mode are
nl
affected. All others maintain their independence.
Fully redundant dual supervisor modules maintain full
functionality.
Domain IDs are restricted to 97–127.
Can still be used to directly connect two MDS-9000
switches together, even while in interoperability mode.
However, they cannot be used to directly connect to a
non-MDS switch. Standard E_Ports are required to
connect to non-MDS switches.
Only the active zoneset is propagated. Up to 2,000
zones can be supported by the MDS-9000. The default
zone policy changes to deny.
Can still be used to fully manage the MDS-9000, and
create zones to be distributed to the non-MDS
nl
platforms. Fabric Manager can still view the entire
mixed topology.
SSH, Telnet, SNMP-v3 are supported.
