HP StorageWorks Fabric Interoperability: Merging Fabrics Based on M-series and B-series Fibre Channel Switches Application Notes (AA-RUQQL-TE, November 2009)

Table 9 lists M-series support for B-series DH group support.
Table 9 B-series DH group types
M-series supportDH group type
Yes0, 1, 2, 3, 4
Yes0 (DH Null option)
No1 (1,024-bit key)
No2 (1,280-bit key)
No3 (1,536-bit key)
No4 (2,048-bit key)
When B-series device authentication mode is set to Off or Passive, M-series support does not apply
because these modes are not used for E-Port authentication.
Switch Authentication policy
There are differences in the Switch Authentication policies between the B-series switch and the M-series
switch. These differences do not prevent authentication from working, but do have an effect on how
authentication works between the switches.

Switch authentication policy when the switch secrets are correct
This section assumes that the M-series switch has the appropriate authentication feature keys enabled.
Table 11 shows all the permutations of Switch Authentication policies and whether the switches will
connect. The table information assumes that all switch secrets are set correctly.
The B-series switch Passive mode is different from the M-series switch Off mode in that B-series switches
perform authentication in Passive mode.
