Controlling Switch Access with RADIUS
This example shows how to provide a user logging in from a switch with immediate access to privileged
EXEC commands:
cisco-avpair= "shell:priv-lvl=15"
This example shows how to specify an authorized VLAN in the RADIUS server database:
cisco-avpair= "tunnel-type(#64)=VLAN(13)"
cisco-avpair= "tunnel-medium-type(#65)=802 media(6)"
cisco-avpair= "tunnel-private-group-ID(#81)=vlanid"
This example shows how to apply an input ACL in ASCII format to an interface for the duration of this
connection:
cisco-avpair= "ip:inacl#1=deny ip 10.10.10.10 0.0.255.255 20.20.20.20 255.255.0.0"
cisco-avpair= "ip:inacl#2=deny ip 10.10.10.10 0.0.255.255 any"
cisco-avpair= "mac:inacl#3=deny any any decnet-iv"
This example shows how to apply an output ACL in ASCII format to an interface for the duration of this
connection:
cisco-avpair= "ip:outacl#2=deny ip 10.10.10.10 0.0.255.255 any"
Other vendors have their own unique vendor-IDs, options, and associated VSAs. For more information
about vendor-IDs and VSAs, see RFC 2138, "Remote Authentication Dial-In User Service (RADIUS)."
Beginning in privileged EXEC mode, follow these steps to configure the switch to recognize and use
VSAs:
Command
Step 1
configure terminal
Step 2
radius-server vsa send [accounting |
authentication]
Step 3
end
Step 4
show running-config
Step 5
copy running-config startup-config

Purpose
Enter global configuration mode.
Enable the switch to recognize and use VSAs as defined by RADIUS IETF
attribute 26.
(Optional) Use the accounting keyword to limit the set of recognized
•
vendor-specific attributes to only accounting attributes.
(Optional) Use the authentication keyword to limit the set of
•
recognized vendor-specific attributes to only authentication attributes.
If you enter this command without keywords, both accounting and
authentication vendor-specific attributes are used.
Return to privileged EXEC mode.
Verify your settings.
(Optional) Save your entries in the configuration file.
