Code CoA Error Cause Description

SR OS

201

Residual Session Context Removed

Residual Session Context Removed is sent in response to a Disconnect-Request if one or more user sessions are no longer active, but residual session context was found and successfully removed. This value is only sent within a Disconnect-ACK and must not be sent within a CoA-ACK, Disconnect-NAK, or CoA-NAK.

202

Invalid EAP Packet (Ignored)

Invalid EAP Packet (Ignored) is a non-fatal error that must not be sent by implementations of this specification.

401

Unsupported Attribute

Unsupported Attribute is a fatal error sent if a Request contains an attribute (such as a Vendor-Specific or EAP-Message Attribute) that is not supported.

402

Missing Attribute

Missing Attribute is a fatal error sent if critical attributes (such as NAS or session identification attributes) are missing from a Request.

403

NAS Identification Mismatch

NAS Identification Mismatch is a fatal error sent if one or more NAS identification attributes do not match the identity of the NAS receiving the Request.

404

Invalid Request

Invalid Request is a fatal error sent if some other aspect of the Request is invalid, such as if one or more attributes (such as EAP-Message Attributes) are not formatted properly.

405

Unsupported Service

Unsupported Service is a fatal error sent if a Service-Type Attribute included with the Request is sent with an invalid or unsupported value. This error cannot be sent in response to a Disconnect-Request.

406

Unsupported Extension

Unsupported Extension is a fatal error sent because of a lack of support for an extension such as Disconnect and, or CoA packets.

This is typically be sent by a proxy receiving an ICMP port unreachable message after attempting to forward a CoA-Request or Disconnect-Request to the NAS.

407

Invalid Attribute Value

Invalid Attribute Value is a fatal error sent if a CoA-Request or Disconnect-Request contains an attribute with an unsupported value.

501

Administratively Prohibited

Administratively Prohibited is a fatal error sent if the NAS is configured to prohibit honoring of CoA-Request or Disconnect-Request packets for the specified session.

502

Request Not Routable (Proxy)

Request Not Routable is a fatal error that may be sent by a proxy and must not be sent by a NAS. It indicates that the proxy was unable to determine how to route a CoA-Request or Disconnect-Request to the NAS. Example, this can occur if the required entries are not present in the proxy's realm routing table.

503

Session Context Not Found

Session Context Not Found is a fatal error sent if the session context identified in the CoA-Request or Disconnect-Request does not exist on the NAS.

504

Session Context Not Removable

Session Context Not Removable is a fatal error sent in response to a Disconnect-Request if the NAS was able to locate the session context, but could not remove it for some reason. It must not be sent within a CoA-ACK, CoA-NAK, or Disconnect-ACK, only within a Disconnect-NAK.

505

Other Proxy Processing Error

Other Proxy Processing Error is a fatal error sent in response to a CoA or Disconnect-Request that could not be processed by a proxy, for reasons other than routing.

506

Resources Unavailable

Resources Unavailable is a fatal error sent when a CoA or Disconnect-Request could not be honored because of a lack of available NAS resources (memory, non-volatile storage, and so on).

507

Request Initiated

Request Initiated is a fatal error sent by a NAS in response to a CoA-Request including a Service-Type Attribute with a value of Authorize Only. It indicates that the CoA-Request has not been honored, but that the NAS is sending one or more RADIUS Access-Requests including a Service-Type Attribute with value Authorize Only to the RADIUS server.

508

Multiple Session Selection Unsupported

Multiple Session Selection Unsupported is a fatal error sent by a NAS in response to a CoA-Request or Disconnect-Request whose session identification attributes match multiple sessions, where the NAS does not support Requests applying to multiple sessions.

Table: RADIUS Disconnect Message [101] Error-Cause values for IPsec tunnel lists the possible [101] Error-Cause attribute values generated in the SR OS in response to a Disconnect Message targeting an IPsec tunnel.

Table: RADIUS Disconnect Message [101] Error-Cause values for IPsec tunnel
Code CoA Error Cause Description

404

Invalid Request

A fatal error sent if some other aspect of the Disconnect-Request is invalid, such as multiple tunnel identifications present in the request.

503

Session Context Not Found

A fatal error sent if the tunnel identified in the Disconnect-Request does not exist.

504

Session Context Not Removable

A fatal error sent if all identified tunnels belong to a tunnel group in MC-IPsec standby status.
