1 MRF Media Interface Configuration Failure Alarm Description

The alarm is a primary alarm. The alarm is issued by the MrfMediaInterface MO. The severity of the alarm is Major.

The alarm indicates that there are no free media IP addresses in the MO-based IP address pool.

The alarm is raised when the IP media interface setup fails because there are no free media IP addresses defined in the MrfNetworkIpPool MO.

The possible alarm causes and fault locations are explained in the table below.

Fault Location

Impact

No IP address is allocated to IP media interface.

IP media interface configuration fails as no IP address can be allocated.

There is no free IP address in the MO-based pool for IP media interfaces.

2 Procedure

These procedures describe how to cease an MRF Media IP Interface Configuration Failure alarm.

2.1 Cease the Alarm by Adding Another IP Pool

To cease the MRF Media IP Interface Configuration Failure alarm, the MO-based IP pool must be extended, either by unlocking a locked IP pool, or by adding another MrfNetworkIpPool MO so that a larger IP pool is available for media IP interfaces.

Note: The ranges of the pools are not required to be adjacent, but the subnet mask and gateway of all pools belonging to the same network interface need to be the same.

Prerequisites

  • An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

Steps

  1. List all the IP pools by issuing the following command:

    >show -v -r ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1

    Check the output for any MrfNetworkIpPool MOs with attribute ipPoolState LOCKED.

    • If there are locked IP pools, consider unlocking them by changing the attribute ipPoolState to UNLOCKED.

      This triggers the allocation of free IP addresses from that pool.

      If the alarm is still active, continue with the next step.

    • If there are no locked IP pools, continue with the next step.

  2. In the MOM, navigate to ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1, enter Config mode, and create a MrfNetworkIpPool MO:
    >ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1
    (ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1)>configure
    (config-ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1)>MrfNetworkIpPool=1
  3. Navigate to the ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1,MrfNetworkIpPool=1 MO and enter Config mode:
    ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1,MrfNetworkIpPool=1
    (ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1,MrfNetworkIpPool=1)>configure
  4. Define the starting value of the IP pool range:
    (config-ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1,MrfNetworkIpPool=1)>ipPoolRangeStart=<IP_pool_start_address>
    Note: The IP pool range starting value can be an IPv4 or an IPv6 address.
  5. Define the ending value of the IP pool range:
    (config-ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1,MrfNetworkIpPool=1)>ipPoolRangeEnd=<IP_pool_end_address>
    Note: The IP pool range ending value can be an IPv4 or an IPv6 address.
  6. Commit the changes:
    (config-ManagedElement=1,MediaResourceFunction=1,MrfConfiguration=1,MrfNetworkIpPool=1)>commit
