The port number of the secondary RADIUS server used for WLAN security. {{param}} is only applicable when {{param|ModeEnabled}} is an Enterprise type (i.e. {{enum|WPA-Enterprise|ModeEnabled}}, {{enum|WPA2-Enterprise|ModeEnabled}} or {{enum|WPA-WPA2-Enterprise|ModeEnabled}}). If this parameter is not implemented, the secondary RADIUS server will use the same port number as the primary RADIUS server. The secret used for handshaking with the secondary RADIUS server {{bibref|RFC2865}}. If this parameter is not implemented, the secondary RADIUS server will use the same secret as the primary RADIUS server. This object contains the parameters related to RADIUS accounting functionality for the access point. Enables or disables accounting functionality for the access point. The IP Address of the RADIUS accounting server. The IP Address of a secondary RADIUS accounting server. The client can forward requests to the secondary server in the event that the primary server is down or unreachable, or after a number of tries to the primary server fail, or in a round-robin fashion. {{bibref|RFC2866}} The port number of the RADIUS server used for accounting.

If this parameter is not implemented, the secondary RADIUS server will use the same secret as the primary RADIUS server. Specifies the default interim accounting interval in {{units}}, which is used for service accounting when the ''Acct-Interim-Interval'' attribute is not configured. {{bibref|RFC2869|Section 2.1}} The value MUST NOT be smaller than 60. The value SHOULD NOT be smaller than 600, and careful consideration should be given to its impact on network traffic {{bibref|RFC2869|Section 5.16}}. A value of 0 means no interim accounting messages are sent. Any {{enum|Tunneled|Type}} IP interface instances instantiated by the CPE MUST NOT have any statistics, writable parameters, IP addresses or IPv6 prefixes. Any read-only parameters, e.g. {{param|Status}}, MUST return the same information as for the corresponding {{enum|Tunnel|Type}} interface. The reason for these rules is that {{enum|Tunneled|Type}} IP interfaces exist only in order to be the targets of references (within the data model) and do not model any concepts over and above those already modeled by the {{enum|Tunnel|Type}} IP interfaces.

These statistics include all IPsec traffic, i.e. all IKEv2 negotiation, IKEv2 SAs and child SAs. The CPE MUST reset global IPsec Stats parameters (unless otherwise stated in individual object or parameter descriptions) either when IPsec is disabled ({{param|.IPsec.Enable}} is set to {{false}}) or when IPsec is enabled ({{param|.IPsec.Enable}} is set to {{true}}). The total number of times an IPsec negotiation failure has occurred. The total number of {{units}} sent by IPsec. The total number of {{units}} received by IPsec. The total number of {{units}} sent by IPsec. The total number of {{units}} received by IPsec. The total number of {{units}} discarded by IPsec due to any error.

The total number of {{units}} discarded by IPsec due to replay errors. The total number of {{units}} discarded by IPsec due to policy errors. The total number of {{units}} discarded by IPsec due to errors other than unknown SPI, decryption, integrity, replay or policy errors. This can include packets dropped due to a lack of receive buffers. Filter table that represents the IPsec Security Policy Database (SPD) {{bibref|RFC4301|Section 4.4.1}} selection criteria. Each (ordered) entry defines a set of selection criteria and references a {{object|#.Profile}} table entry that specifies how matching packets will be processed. SPD filtering is performed for all packets that might need to cross the IPsec boundary {{bibref|RFC4301|Section 3.1}}. Given that IPsec operates at the IP level, this means that SPD filtering conceptually occurs after bridging and before routing. For enabled table entries, if {{param|Interface}} is not a valid reference and {{param|AllInterfaces}} is {{false}}, then the table entry is inoperable and the CPE MUST set {{param|Status}} to {{enum|Error_Misconfigured|Status}}. Enables or disables this IPsec Filter table entry. The status of this IPsec Filter table entry. {{enum}} The {{enum|Error_Misconfigured}} value indicates that a necessary configuration value is undefined or invalid. The {{enum|Error}} value MAY be used by the CPE to indicate a locally defined error condition. Position of the {{object}} entry in the order of precedence. A value of ''1'' indicates the first entry considered (highest precedence). For each packet, the highest ordered entry that matches the filter criteria is applied. All lower order entries are ignored. When this value is modified, if the value matches that of an existing entry, the {{param}} value for the existing entry and all lower {{param}} entries is incremented (lowered in precedence) to ensure uniqueness of this value. A deletion causes {{param}} values to be compacted. When a value is changed, incrementing occurs before compaction. The value of {{param}} on creation of a {{object}} table entry MUST be one greater than the largest current value (initially assigned the lowest precedence). {{datatype|expand}} SPD selection criterion. {{reference}} This specifies the ingress interface associated with the entry. It MAY be a layer 1, 2 or 3 interface. However, the types of interfaces for which filters can be instantiated is a local matter to the CPE. SPD selection criterion. This specifies that all ingress interfaces are associated with the entry. If {{true}}, the value of {{param|Interface}} is ignored since all ingress interfaces are indicated. SPD selection criterion. Destination IP address. {{empty}} indicates this criterion is not used, i.e. is ''ANY''. SPD selection criterion. Destination IP address mask. If not {{empty}}, only the indicated network portion of the {{param|DestIP}} address is to be used for selection. {{empty}} indicates that the full {{param|DestIP}} address is to be used for selection. If {{false}}, the rule matches only those packets that match the (masked) {{param|DestIP}} entry, if specified. If {{true}}, the rule matches all packets except those that match the (masked) {{param|DestIP}} entry, if specified. SPD selection criterion. Source IP address. {{empty}} indicates this criterion is not used, i.e. is ''ANY''. SPD selection criterion. Source IP address mask.

If {{true}}, the rule matches all packets except those that match the (masked) {{param|SourceIP}} entry, if specified. SPD selection criterion. Protocol number. A value of -1 indicates this criterion is not used, i.e. is ''ANY''. Note that {{bibref|RFC4301}} refers to this as the ''Next Layer Protocol''. It is obtained from the IPv4 ''Protocol'' or the IPv6 ''Next Header'' fields. If {{false}}, the rule matches only those packets that match {{param|Protocol}}, if specified. If {{true}}, the rule matches all packets except those that match {{param|Protocol}}, if specified. SPD selection criterion. Destination port number. A value of -1 indicates this criterion is not used, i.e. is ''ANY''. The value of this parameter is ignored for protocols that do not use ports, e.g. ICMP (1). SPD selection criterion. If specified, indicates a destination port address range from {{param|DestPort}} through {{param}} (inclusive), in which case {{param}} MUST be greater than or equal to {{param|DestPort}}. A value of -1 indicates that no destination port range is specified. If {{false}}, the rule matches only those packets that match {{param|DestPort}} (or port range), if specified. If {{true}}, the rule matches all packets except those that match {{param|DestPort}} (or port range), if specified. SPD selection criterion. Source port number. A value of -1 indicates this criterion is not used, i.e. is ''ANY''. The value of this parameter is ignored for protocols that do not use ports, e.g. ICMP (1). SPD selection criterion. If specified, indicates a source port address range from {{param|SourcePort}} through {{param}} (inclusive), in which case {{param}} MUST be greater than or equal to {{param|SourcePort}}. A value of -1 indicates that no source port range is specified. If {{false}}, the rule matches only those packets that match {{param|SourcePort}} (or port range), if specified. If {{true}}, the rule matches all packets except those that match {{param|SourcePort}} (or port range), if specified. Indicates how packets that match this rule will be processed {{bibref|RFC4301|Section 4.4.1}}. Packet is not allowed to traverse the IPsec boundary; packet will be discarded Packet is allowed to bypass traverse the IPsec boundary without protection Packet is afforded protection as specified by {{param|Profile}} The profile that defines the IPsec treatment for matching packets. {{reference}} If {{param|ProcessingChoice}} is {{enum|Protect|ProcessingChoice}}, {{param}} MUST NOT be {{empty}}. In this case, if it ever becomes {{empty}}, e.g. because the referenced profile is deleted, this IPsec Filter table entry is invalid and {{param|Status}} MUST be set to {{enum|Error_Misconfigured|Status}}. If {{param|ProcessingChoice}} is not {{enum|Protect|ProcessingChoice}}, {{param}} is ignored. Any changes to the referenced profile will have an immediate effect on any established IPsec tunnels. Such changes will often force IKEv2 sessions and child SAs to be re-established. Profile table that represents the IPsec Security Policy Database (SPD) {{bibref|RFC4301|Section 4.4.1}} processing info. Each entry defines the IPsec treatment for packets that match the {{object|#.Filter}} entries that reference the entry. {{datatype|expand}} Controls the maximum number of child Security Association (SA) pairs that can be negotiated by a single IKEv2 session. If a new child SA pair is needed, but the current IKEv2 session already has {{param}} child SA pairs, an additional IKEv2 session (and therefore an additional IPsec tunnel) will be established. A value of 0 means no specific limit. Note that support for more than one child SA pair per IKEv2 session is OPTIONAL {{bibref|RFC5996|Section 1.3}}. The host name or IP address of the remote IPsec tunnel endpoint. If more than one name/address is supplied, they will be tried in turn, i.e. they are in decreasing order of precedence. Identifier of the forwarding policy associated with traffic that is associated with this profile. The forwarding policy can be referenced by entries in the {{object|##.Routing.Router.{i}.IPv4Forwarding}} and {{object|##.Routing.Router.{i}.IPv6Forwarding}} tables, and therefore allows SPD selection criteria to influence the forwarding decision. The "child" security protocol. This is not to be confused with {{object|#.Filter}}.{{param|#.Filter.{i}.Protocol}}, which is an SPD selector that can select packets that already have AH or ESP headers. {{object}}.{{param}} selects whether AH or ESP will be used when encapsulating a packet.

Represents an IPsec tunnel, i.e. a virtual IP interface that models an IPsec tunnel entry point and exit point. A {{object}} instance always references (and has the same lifetime as) a ({{enum|Tunnel|.IP.Interface.{i}.Type}},{{enum|Tunneled|.IP.Interface.{i}.Type}}) {{object|.IP.Interface}} pair. The {{object}} instance models the IPsec-specific concepts, the {{enum|Tunnel|.IP.Interface.{i}.Type}} {{object|.IP.Interface}} instance models the generic concepts, and the {{enum|Tunneled|.IP.Interface.{i}.Type}} {{object|.IP.Interface}} instance exists only so it can be referenced by forwarding or filter rules. {{object}} instances are automatically created (as needed) when {{object|#.Filter}} instances are enabled and disabled. Each instance's {{param|Filters}} parameter references the {{object|#.Filter}} instances that require the {{object}} instance to exist. If this list ever becomes {{empty}}, e.g. because all the referenced {{object|#.Filter}} instances have been disabled or deleted, the CPE MAY choose not to delete the {{object}} instance (and its associated ({{enum|Tunnel|.IP.Interface.{i}.Type}},{{enum|Tunneled|.IP.Interface.{i}.Type}}) {{object|.IP.Interface}} pair).

From the management point of view the new and old IKEv2 SAs are the same SA and MUST be modeled using the same {{object}} instance. The local IP address that this IKEv2 SA was negotiated with. This is assigned via IKEv2 and will also be available via the associated {{object|#.Tunnel}}'s {{param|#.Tunnel.{i}.TunnelInterface}} {{object|##.IP.Interface.{i}.IPv4Address}} or {{object|##.IP.Interface.{i}.IPv6Address}} table (as appropriate).
