Web authentication requires two Cisco Attribute-Value (AV) pair attributes:
The first attribute, priv-lvl=15, must always be set to 15. This sets the privilege level of the user who
is logging into the switch.
The second attribute is an access list to be applied for web-authenticated hosts. The syntax is similar
to 802.1x per-user access control lists (ACLs). However, instead of ip:inacl, this attribute must begin
with proxyacl, and the source field in each entry must be any. (After authentication, the client IP
address replaces the any field when the ACL is applied.)
For example:
proxyacl# 10=permit ip any 10.0.0.0 255.0.0.0
proxyacl# 20=permit ip any 11.1.0.0 255.255.0.0
proxyacl# 30=permit udp any any eq syslog
