MYCERTURL, MYCERTURL_2, MYCERTURL_3

String

Null

Specifies the URL to access the SCEP server. The phone attempts to contact the server only if this parameter is set. Use MYCERTURL_2 and MYCERTURL_3 for additional profiles.

MYCERTKEYLEN, MYCERTKEYLEN_2, MYCERTKEYLEN3

Integer

2048

Specifies the bit length of the public and private keys generated for the SCEP certificate request.

The value is a 4 ASCII numeric digits. The phone supports the values 2048 and 4096. Invalid values are ignored.

The 4096 key size delays boot-up during the initial key generation and certificate enrollment.

Use MYCERTKEYLEN_2 and MYCERTKEYLEN3 for additional profiles.

MYCERTCN, MYCERTCN_2, MYCERTCN_3

String

$SERIALNO

Specifies the Common Name (CN) for the certificate request. This value serves as the username associated with the end entity in the SCEP server. The value must contain at least one macro:

• $SERIALNO: Replaced with the serial number of the phone in uppercase.
• $MACADDR: Replaced with the MAC address of the phone in lowercase (without colon separators).
• $MACADDR_UPPER: Same as$MACADDR
• , but in uppercase.

To enable enhanced certificate renewal in Avaya Aura® System Manager 8.1.3 and later, this value must remain unchanged from the one used in the existing identity certificate.

If a new value is required, remove SCEP_ENTITY_CLASS or delete the existing certificate using DELETE_MY_CERT before reinstalling a new one. Use MYCERTCN_2 and MYCERTCN_3 for additional profiles.

MYCERTDN, MYCERTDN_2, MYCERTDN_3

String

Null

Defines the common Distinguished Name (DN) portion of the SCEP certificate request. This value usually includes information on Organizational Unit, Organization, Location, State, and Country.

To enable enhanced certificate renewal in Avaya Aura® System Manager 8.1.3 and later, this value must remain unchanged from the one used in the existing certificate.

If a new value is required, remove SCEP_ENTITY_CLASS or delete the existing certificate using DELETE_MY_CERT before reinstalling a new one. Use MYCERTDN_2 and MYCERTDN_3 for additional profiles.

MYCERTCAID, MYCERTCAID_2, MYCERTCAID_3

String

CAIdentifier

Specifies the Certificate Authority (CA) Identifier. Some CA servers require a specific identifier string for GetCA requests. If required, set this parameter to match the CA requirements. Use MYCERTCAID_2 and MYCERTCAID_3 for additional profiles.

SCEPENCALG, SCEPENCALG_2, SCEPENCALG_3

Numeric

0

Specifies SCEP Encryption Algorithm.

Value operation:

• 0: DES
• 1: AES-256

For certificate profiles 2 and 3, use SCEPENCALG_2 and SCEPENCALG_3.

SCEPPASSWORD, SCEPPASSWORD_2, SCEPPASSWORD_3

String

$SERIALNO

Specifies a challenge password to use with SCEP. The value of SCEPPASSWORD, if non-null, is included in the Challenge Password attribute of SCEP certificate signing requests.

If the value contains$SERIALNO,$SERIALNO

is replaced by the phone serial number in uppercase. If the value contains$MACADDR,$MACADDR

is replaced by the phone MAC address in lowercase without the colon separators.$MACADDR_UPPERis replaced by the value in uppercase.

To use enhanced certificate renewal in System Manager 8.1.3 and later, the SCEPPASSWORD value cannot be empty. It can be set to a variable such as$MACADDRor$SERIALNO

.

If renewal or enrollment of a certificate is performed using standard SCEP protocol, the parameter SCEP_ENTITY_CLASS must be removed.

For certificate profiles 2 and 3, use SCEPPASSWORD_2 and SCEPPASSWORD_3.

SCEP_USAGE, SCEP_2_USAGE, SCEP_3_USAGE

String

ALL

Specify the list of services for which the certificate assigned to the SCEP profile should be applied.

Must be a comma-separated list, case-insensitive.

Available services are the following:

SIP

Provisioning

802.1x

LDAP

Ring Central

Push

PPM

XSI

Syslog

All

Default is All.

You can exclude one service using ! before the service name in the list. For example, All,!SIP will assign all available services except SIP.

MYCERTRENEW, MYCERTRENEW_2, MYCERTRENEW_3

Numeric

90

Specifies the percentage of the validity period of the certificate, after which the phone initiates the renewal procedure through SCEP. The value determines the renewal time based on the validity period of the certificate. The range is from 1% to 99%.

For example, if the MYCERTRENEW is set to 90 and the validity of the certificate is 365 days, renewal begins 36.5 days before expiration ((365)-(365*90%)= 36.5 days).

After a successful renewal, the phone uses the new certificate for all new TLS connections while existing TLS connections remain active.

If the phone fails to renew the certificate, it retries every 24 hours.

When using Avaya Aura® System Manager as the SCEP Certificate Authority (CA), ensure that the End Entity Status for the device is set to "New".

For additional certificate profiles, use MYCERTRENEW_2 and MYCERTRENEW_3.
