CoA Examples

Upon receiving a CoA or Disconect packet the server identifies all active sessions matching the provided User-Name and/or Acct-Session-Id attributes. The server sends a subrequest packet for every identified session to the correponding NAS.

To disconnect a specific session of a user:

$ echo 'Acct-Session-Id = "769df3 312343"' | \
    radclient 127.0.0.1 disconnect testing123

To disconnect all sessions belonging to a user:

$ cat <<EOF | radclient 127.0.0.1 disconnect testing123
    User-Name = bob

To update the connection parameters of a specific session:

$ cat <<EOF | radclient 127.0.0.1 coa testing123
    User-Name = bob
    Acct-Session-Id = 769df3 312343

To update the connection parameters of all sessions belonging to a user:

$ cat <<EOF | radclient 127.0.0.1 coa testing123
    User-Name = bob
    Vendor-Specific.Cisco.AVPair = "subscriber:sub-qos-policy-out=q_out_uncapped"
    EOF
