198 CHAPTER 7: AAA COMMANDS
You can configure a rule either for wireless access to an SSID, or for wired
access through a WX switch’s wired authentication port. If the rule is for
wireless access to an SSID, specify the SSID name or specify any to match
on all SSID names. If the rule is for wired access, specify wired instead of
an SSID name.
If you specify multiple authentication methods in the set authentication
last-resort command, MSS applies them in the order in which they
appear in the command, with these results:
If the first method responds with pass or fail, the evaluation is final.
If the first method does not respond, MSS tries the second method,
and so on.
However, if local appears first, followed by a RADIUS server group, MSS
overrides any failed searches in the local WX database and sends an
authentication request to the server group.
MSS uses a last-resort authentication rule under the following conditions:
The client is not denied access by 802.1X or does not support 802.1X.
The client’s MAC address does not match a MAC authentication rule.
The fallthru method is last-resort. (For a wireless authentication rule,
the fallthru method is specified by the set service-profile
auth-fallthru command. For a wired authentication rule, the fallthru
method is specified by the auth-fall-thru option of the set port type
wired-auth command.)
For wireless access, MSS appends the requested SSID name to the user
name last-resort. For example, if the requested SSID is mycorp, MSS
attempts to authenticate the user last-resort-mycorp. If the RADIUS server
or local database used as the authentication method has the user
last-resort-mycorp, access is granted. Otherwise, access is denied.
If the SSID specified in the last-resort authentication rule is any, MSS
searches for user last-resort-any. The any in the username is not a
wildcard. The username must be last-resort-any, exactly as spelled here.
Examples — The following command configures a last-resort
authentication rule in the local WX database for SSID mycorp:
WX4400# set authentication last-resort ssid mycorp local
success: change accepted.
