Cisco Catalyst 2960-X User Manual

If more than one session identification attribute is included in the message, all the attributes must match the
session or the switch returns a Disconnect- negative acknowledgment (NAK) or CoA-NAK with the error
code “Invalid Attribute Value.”
The packet format for a CoA Request code as defined in RFC 5176 consists of the fields: Code, Identifier,
Length, Authenticator, and Attributes in Type:Length:Value (TLV) format.

The attributes field is used to carry Cisco vendor-specific attributes (VSAs).
For CoA requests targeted at a particular enforcement policy, the device returns a CoA-NAK with the error
code “Invalid Attribute Value” if any of the above session identification attributes are included in the message.

CoA ACK Response Code
If the authorization state is changed successfully, a positive acknowledgment (ACK) is sent. The attributes
returned within CoA ACK will vary based on the CoA Request and are discussed in individual CoA Commands.
CoA NAK Response Code
A negative acknowledgment (NAK) indicates a failure to change the authorization state and can include
attributes that indicate the reason for the failure. Use show commands to verify a successful CoA.
CoA Request Commands

Cisco:Avpair=“subscriber:command=reauthenticate”
Reauthenticate host
This is a standard disconnect request that does not
require a VSA.
Terminate session
Cisco:Avpair=“subscriber:command=bounce-host-port”
