Chapter 31 Advanced Features and Concepts
Configuring the Switch for Interoperability
R_A_TOV Verify that the Resource Allocation Time Out Value timers
match exactly.
Trunking Trunking is not supported between two different vendor
switches. This feature may be disabled on a per port or per
switch basis.
Default zone The default zone behavior of permit (all nodes can see all other
nodes) or deny (all nodes are isolated when not explicitly placed
in a zone), may change.
Zoning attributes Zones may be limited to the pWWN and other proprietary
zoning methods (physical port number), may be eliminated.
Note
Brocade uses the cfgsave command to save fabric-wide
zoning configuration. This command doesn’t have any
effect on Cisco MDS 9000 Family switches if they are
part of the same fabric. You must explicitly save the
configuration on each switch in the Cisco MDS 9000
Family using the
copy running start command.
Zone propagation Some vendors do not pass the full zone configuration ( zoneset )
to other switches, only the active zoneset gets passed.
Verify that the active zoneset or zone configuration has correctly
propagated to the other switches in the fabric.
VSAN Interop mode only affects the specified VSAN.
TE ports and PortChannels 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. TE ports and PortChannels can still be used
to connect an MDS to other MDS switches even when in
interop
mode.
FSPF 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.
Domain reconfiguration
disruptive 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.
Domain reconfiguration
nondisruptive 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.
Name server Verify that all vendors have the correct values in their respective
name server database.
IVR Prior to Cisco MDS SAN-OS Release 1.3(4a), IVR-enabled
VSANs can only be configured in no interop (default) mode or
in interop mode 1. As of Cisco MDS SAN-OS Release 1.3(4a),
IVR-enabled VSANs can be configured in no interop (default)
mode or in any interop mode.
