PDIF Service Configuration Mode Commands

PDIF Service Configuration Mode Commands
 
The PDIF Service Configuration Mode is used to configure the properties required for a mobile station to interface with a Packet Data Interworking Function (PDIF).
note_smallImportant: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
aaa attribute
Sets the system attributes for AAA messages.
Product
PDIF
Privilege
Security Administrator, Administrator
Syntax
aaa attribute { 3gpp2-bsid string | 3gpp2-service-option integer | calling-station-id integer | 3gpp2-serving-pcf ip-address }
no aaa attribute
default aaa attribute 3gpp2-service-option integer
no
Removes a previously configured AAA attribute.
default
Returns the specified aaa attribute to the original default system settings.
3gpp2-bsid string
Specifies the base-station ID and consists of the SID + NID + CELLID.
string must contain 12 hexadecimal upper-case ASCII characters.
3gpp2-service-option integer
Specifies the radius attribute value when sending authentication and accounting messages as an integer from 0 through 32767. Default: 4095
calling-station-id integer
Specifies the calling station phone number as a sequence of 1 through 15 digits.
3gpp2-serving-pcf ip-address
Use this command to generate attribute values without creating a new ASR 5000 image.
Usage
If the RADIUS protocol is being used, accounting messages can be sent over a AAA interface to the RADIUS server.
3gpp2-serving-pcf attribute value (if configured) is sent in both RADIUS authentication and accounting messages. If the attribute value is not configured (or explicitly “not configured” using the no keyword), RADIUS attributes are still included with just type and length. This is because inclusion/exclusion of RADIUS attributes are still controlled through the dictionary, not via the CLI.
Example
The following command identifies the base station ID:
aaa attribute 3gpp2-bsid 0ab2389acb3
aaa authentication
Sets the aaa authentication for first and second phase authentication when multiple authentication is configured on the system.
Product
PDIF
Privilege
Security Administrator, Administrator
Syntax
aaa authentication { { first-phase | second-phase } | { context-name name aaa-group name } }
no aaa authentication { first-phase | second-phase }
no aaa authentication { first-phase | second-phase }
Removes any existing authentication configuration.
first-phase context-name name aaa-group name
Specifies the context name and the aaa group name configured in the context for the first authentication phase.
note_smallImportant: First phase authentication is mandatory when multiple authentication is configured on the system.
•
context-name name: Specifies the context where the aaa server group is defined as an alphanumeric string of 1 through 79 characters.
•
aaa-group name: Specifies the name of the aaa-group to be used for authentication as an alphanumeric string of 1 through 79 characters.
second-phase context-name name aaa-group name
Specifies the context name and the aaa group name configured in the context for the second authentication phase.
•
context-name name: Specifies the context where aaa server group is defined as an alphanumeric string of 1 through 79 characters.
•
aaa-group name: Specifies the name of the aaa-group to be used for authentication as an alphanumeric string of 1 through 63 characters.
Usage
Two phase-authentication happens in IKEv2 setup for setting up the IPSec session. The first authentication uses Diameter AAA EAP method and second authentication uses RADIUS AAA authentication. The same AAA context may be used for both authentications. PDIF service allows you to specify only a single AAA group, which could normally be used for the first authentication method.
A given AAA group only supports either Diameter or RADIUS authentication. If the NAI in the first authentication is different from NAI in the second authentication each NAI can point to a different domain profile in the PDIF. Each domain profile may be configured with each AAA group, one for Diameter and the other for RADIUS.
Example
Use the following to configure first-phase authentication for an aaa group named aaa-10 in the PDIF context:
first-phase context-name pdif aaa-group aaa-10
bind
Binds the service IP address to a crypto template and configures the number of sessions the PDIF can support.
Product
PDIF
Privilege
Security Administrator, Administrator
Syntax
bind address address { crypto-template string } [ max-sessions number ]
no bind
no
Removes a previously configured binding.
address
Specifies the IP address of the service.
crypto-template string
Specifies the name of the crypto template to be bound to the service as an alphanumeric string of 0 through 127 characters.
max-sessions number
Specifies the maximum number of sessions to be supported by the service as an integer from 0 to 3000000. Default: 3000000
Usage
Binds the IP address used as the connection point for establishing the IKEv2 sessions to the crypto template. It can also define the number of sessions the PDIF can support.
Example
The following command binds a service with the IP address 13.1.1.1 to the crypto template T1 and sets the maximum number of sessions to 2000000:
bind address 13.1.1.1 crypto-template T1 max-sessions 200000

aaa attribute 3gpp2-service-option
Configures the default value 4095.
duplicate-session-detection
Configures the default to be NAI-based.
hss { failure-handling mac-address-validation-failure | mac-address-validation | update-profile }
Configures the HSS server defaults:
failure-handling mac-address-validation-failure: By default, the MAC address is validated by IMS-Sh interface.
•
mac-address-validation: By default, validating the MAC address is disabled.
•
update-profile: By default, updating the PDIF profile is disabled.
ip source-violation ( drop-limit | period }
Configures IP source-violation detection defaults.
•
drop-limit: Default number of ip source violations permitted in detection period before the call is dropped is 10.
•
period: Default detection period is 120 seconds.
setup-timeout
Default call setup time limit is 60 seconds.
subscriber name
Configures the default subscriber name. name is a string of 1-127 characters.
username mac-address-stripping
Default is to disable stripping the MAC address from the username.
Usage
Configures the default settings for a given parameter.
Example
Use the following example to configure the default call setup time limit:
default setup-timeout
duplicate-session-detection
Configures the PDIF to detect duplicate call sessions using old IMSI or NAI addresses and clear old call information.
Product
PDIF
Privilege
Security Administrator, Administrator
Syntax
[ no | default ] duplicate-session-detection { imsi-based | nai-based }
no
Stops duplicate session detection.
default
Configures the default setting, which is NAI-based detection.
imsi-based
Configures the PDIF to detect duplicate call sessions based on the IMSI address.
nai-based
Configures the PDIF to detect duplicate call sessions based on the NAI address. This is the default setting.
Usage
If an MS leaves the Wi-Fi coverage area and subsequently comes back online, it may initiate a new session setup procedure. After both the device authentication with HSS and the subscriber authentication with AAA server are completed, PDIF runs the internal mechanism to see whether there was any other session bound with the same IMSI. If an old session is detected, PDIF starts clearing this old session by sending a proxy-MIP Deregistration request to the HA. PDIF resumes new session setup by sending a proxy-MIP registration request. When the old session is aborted, PDIF sends Diameter STR messages and RADIUS Acct STOP messages to corresponding AAA servers.
PDIF allows duplicate session detection based on either the NAI or IMSI addresses. When detecting based on NAI, it is the first-phase (device authentication) NAI that is used.
Example
The following command configures duplicate session detection to use IMSI addressing:
duplicate-session-detection imsi

failure-handling mac-address-validation-failure
Configures how the HSS is to handle errors.
If HSS returns a list of MAC addresses and if PDIF fails to match the subscriber MAC address against the list, the session is always terminated.
action { continue | terminate }
Configures the action to be performed depending on the failure type.
•
continue: Ignores a mac-address-validation-failure and continue the session.
•
terminate: Terminates the session on a mac-address-validation-failure.
mac-address-validation
If mac-address-validation is enabled, the PDIF queries the HSS for a list of MAC addresses associated with the Mobile Directory Number (MDN). Default: Disabled
update-profile
Update the HSS with the subscriber profile. Default: Disabled
Usage
An HSS provides MAC address validation and store part of the subscriber profile. This command enables or disables validation and profile updates, and configures how the system responds to failures: terminate or continue a session.
An ims-sh-service and Diameter interface need to be configured to communicate with the HSS.
Example
The following example enables mac-address validation:
hss mac-address-validation
ims-sh-service
Associates the IMS-Sh-service parameters.
Product
PDIF
Privilege
Security Administrator, Administrator
Syntax
ims-sh-service name name
no ims-sh-service name name
no
Removes a previously configured IMS-Sh-service.
name
Names the IMS-Sh-service in the pdif-service context.
Usage
This command is used to name the IMS-Sh-service.
Example
The following command names the IMS-Sh-service ims1:
ims-sh-service name imsi1
ip source-violation
Sets the parameters for IP source validation. Source validation is useful if packet spoofing is suspected or for verifying packet routing and labeling within the network.
Source validation requires that the source address of the received packets matches the IP address assigned to the subscriber (either statically or dynamically) during the session.
Product
PDIF
Privilege
Security Administrator, Administrator
Syntax
ip source-violation { clear-on-valid-packet | drop-limit num | period secs }
no ip source-violation clear-on-valid-packet
clear-on-valid-packet
Configures the service to reset the reneg-limit and drop-limit counters after receipt of a properly addressed packet. Default: disabled
drop-limit num
Sets the number of allowed source violations within a detection period before forcing a call disconnect. If num is not specified, the value is set to the default.
num is an integer from 1 to 1000000. Default: 10
period secs
Sets the length of time (in seconds) for a source violation detection period to last.
If secs is not specified, the value is set to the default.
secs is an integer from 1 to1000000. Default: 120
Usage
This function is intended to allow the operator to configure a network to prevent problems such as when a user gets handed back and forth between two PDIFs a number of times during a handoff scenario.
This function operates in the following manner:
When a subscriber packet is received with a source address violation, the system increments the IP source-violation drop-limit counter and starts the timer for the IP-source violation period. Every subsequent packet received with a bad source address during the IP-source violation period causes the drop-limit counter to increment.
For example, if the drop-limit is set to 10, after 10 source violations, the call is dropped. The period timer continues to count throughout this process.
Example
The following command sets the drop limit to 15 and leaves the other values at their defaults:
ip source-violation drop-limit 15
mobile-ip
Sets the MIP FA context for the specific PDIF service.
