Known Problems

25

CLI allows set authentication dot1x command 
with invalid combination of pass-through and 
local options. (15562)

The CLI allows you to enter a command such as the 
following:

set authentication dot1x ssid any * pass-through 
local

The pass-through and local AAA methods are mutu-
ally exclusive. Even if a server group named local 
exists, MSS does not use the group. In either case, the 
EAP session fails and the 802.11 session is deauthen-
ticated when the client responds to the first identity 
request. 

Do not name a server group local and do not attempt 
to mix mutually exclusive authentication methods in 
the same command. 

Authentication method 

none

 is invalid for 

network access rules, but is accepted by the CLI. 
(18147, 18157)

AAA rules for administrative access, configured by 

set 

authentication

 commands, allow you to specify 

none

 as the authentication method, as an alternative 

to a RADIUS server group or local. When used for 
administrative access, the method 

none

 immediately 

allows access to the WX administrator. The value 

none

 is not a valid authentication method for net-

work access rules. However, the commands that con-
figure MAC, Web, and last-resort network access 
rules accept the value. This is an invalid configuration 
and can provide unexpected results. The command 

for configuring 802.1X AAA rules does not allow 
none to be specified.

Similarly, 

none

 is invalid for any 

set accounting

 com-

mand, but is accepted by the CLI.

Do not specify 

none

 as an authentication method 

with 

set authentication mac

set authentication 

web

, or 

set authentication last-resort

 commands, 

or with any 

set accounting

 command.

The authentication method 

none

 you can specify for 

administrative access is different from the fallthru 
authentication type none, which applies only to net-
work access. The authentication method 

none

 allows 

access to the WX switch by an administrator. The 
fallthru authentication type none denies access to a 
network user. 

A set authentication mac mac-addr-glob rule 
does not restrict input. (13907)

The

 set authentication mac

 

mac-addr-glob

 com-

mand should accept only a properly formatted MAC 
address or a MAC address glob, which can use an 
asterisk (*) as a prefix or suffix to the MAC address. 
However, the command actually accepts any string.

Provide only properly formatted MAC addresses or 
MAC address globs. For more information, see the 

Wireless LAN Switch and Controller Command Refer-
ence
