E_Port authentication between Fabric OS and M-EOS switches

14

 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. 

 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 

 indicates two-way 

authentication.

Yes!
Connected with

No
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.

Off

Yes
Connected without 
any authentication 
(Fabric builds 
normally). 

Yes*
Connected with 
one-way authentication; 
only one of connected 
switches performs 
Authentication (Fabric 
builds normally).

Yes*
Connected with 
one-way 
authentication; only 
one of connected 
switches performs
