Combining Generation 1, Generation 2, and Generation 3 Modules
for how many extended BB_credits you can assign to a port (except for the maximum and minimum
limits). If necessary, you can take interfaces out of service to make more extended BB_credits available
to other ports.
Combining Generation 1, Generation 2, and Generation 3
Modules
Cisco MDS NX-OS Release 4.1(1) and later supports combining Generation 1, Generation 2, and
Generation 3 modules and switches with the following considerations:
• MDS NX-OS Release 4.1(1) and later features are not supported on Generation 1 switches and
modules.
• Generation 3 modules do not support the following Generation 1 hardware:
– Supervisor 1 module
– 4-Port IP Storage Services module
– 8-Port IP Storage Services module
– MDS 9216 Switch
– MDS 9216A switch
– MDS 9020 switch
– MDS 9120 switch
– MDS 9140 swtich
• Supervisor-1 modules must be upgraded to Supervisor-2 modules on the MDS 9506 and MDS 9509
Directors.
• IPS-4 and IPS-8 modules must be upgraded to the MSM-18/4 Multiservice modules.
• Fabric 1 modules must be upgraded to Fabric 2 modules on the MDS 9513 Director to use the
48-port or the 24-port 8-Gbps module, and the Fabric 2 modules must be configured in active-active
mode.
• MDS Fabric Manager Release 4.x supports MDS SAN-OS Release 3.x and NX-OS 4.x in mixed
mode through Interswitch Link (ISL) connectivity.
Note When a Cisco or a other vendor switch port is connected to a Generation 1 module port (ISL
connection), the receive buffer-to-buffer credits of the port connected to the Generation 1 module port
should not exceed 255.
Port Indexes
Cisco MDS 9000 switches allocate index identifiers for the ports on the modules. These port indexes
cannot be configured. You can combine Generation 1, Generation 2, and Generation 3 switching
modules, with either Supervisor-1 modules or Supervisor-2 modules. However, combining switching
modules and supervisor modules has the following port index limitations:
• Supervisor-1 modules only support a maximum of 252 port indexes, regardless of the type of
switching modules.
