E_Port authentication between Fabric OS and M-EOS switches
14
Table 59 describes the device authentication mode.
Switch authentication policy
There are differences in the Switch Authentication policies between the Fabric OS switch and the
M-EOS switch. The Fabric OS switches have four different settings, which are Passive, Active, On,
and Off. M-EOS switches only have On and Off. 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-EOS switch has the appropriate authentication feature keys
enabled.
Table 60 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 two places
where Yes* appears in the table, are cases where the M-EOS switch authentication is Off.
The Fabric OS switch mode Passive is different from the M-EOS switch mode Off in that Fabric OS
switches perform authentication in Passive mode. This is why a Yes! in
Table 60 indicates two-way
authentication.

E_Port does not connect
(Authentication Rejected).
When the Fabric OS switch
generates the reject, it will
disable the Fabric OS port.
When the M-EOS switch
generates the reject, it will
go to an invalid attachment
state.
