ID

Detection

Rule

2001

Incorrect configuration

An IP address must be configured except if the value of the Under Construction attribute is true (check box selected).

For NOC communication modules, IP address A is optional.

2002

Alert

IP addresses must be associated to a valid logical network except if the value of the Under Construction attribute is true (check box selected).

2003

Incorrect configuration

IP addresses must satisfy the following rules to be valid:

  • Must start at 1.0.0.0.

  • Cannot be a class D address (>223.255.255.255).

  • Cannot be a loopback address (starting with 127).

  • Cannot start with 169.254, which is reserved for Automatic Private IP Addressing (APIPA) in a class B network.

  • Cannot be equal to the subnet address.

  • Cannot be equal to the broadcast address.

NOTE: The value 0.0.0.0 is accepted for both SNMP managers. Refer also to rule 6028.

2004

Incorrect configuration

(Alert for BMENUA0100 and BMENUA100.2 modules)

An IP address must be valid for the configured logical network.

An IP address cannot be equal to the subnet address or broadcast address.

When the NTP service of a module is configured as NTP Client, the primary and secondary NTP server IP addresses must satisfy the following rules:

  • They must belong to the logical network of one of the enabled interfaces of the module (for example, the embedded or the backplane interface).

  • They cannot be equal to the network address of this logical network.

  • They cannot be equal to the broadcast address. That is, an address that ends with the following value regardless of the value of the subnet mask:

    • 255.255.255 in a class A network.

    • 255.255 in a class B network.

    • 255 in a class C network.

NOTE: The rules do not apply to BMENOC03?1 communication modules.
NOTE: The value 0.0.0.0 is accepted.

The IP address of either SNMP manager is invalid if it ends with the following value regardless of the value of the subnet mask:

  • 255.255.255 in a class A network.

  • 255.255 in a class B network.

  • 255 in a class C network.

2005

Incorrect configuration

An IP address must be unique in the logical network.

2006

Alert

The same IP address must not be used in different logical networks of a system project.

2007

Incorrect configuration

For the following modules, when IPv6 addresses are enabled and/or selected, the IPv6 addresses of the embedded interface and of the primary and secondary NTP servers cannot be null.

  • BMENUA0100

  • BMENUA0100.2

2008

Alert

An IPv6 address must be unique within the system project.

The rule applies to the following modules:

  • BMENUA0100

  • BMENUA0100.2

2009

Incorrect configuration

The IP address of each CRA adapter module in an M580 PAC must be unique .
