8 MANAGING THE TENANT OAM ADDRESS AND HOSTNAME TABLES
Within the Tenant OAM MIB, there are two (2) tables used to capture the current IP Addresses
and Hostnames of all CPUs that are associated with a given tenant sector. The ordering of the
CPUs in the MIB tables is such that the RAN CPUs are listed first from 1-8, followed by the
Hub CPUs. The RAN ordering from 1-8 is important so that the RAN CPUs can be correlated
to the RAN ID values used throughout the Tenant OAM MIB.
8.1 RAN Ordering
The IP Address and Hostname tables in the Tenant OAM MIB indicate which RAN, based on
IP address and hostname, corresponds to RAN X, where X is the RAN ID (1-8).
Tenant processing uses a least-recently-used scheme to determine the RAN ID to assign to
newly discovered RANs. When Tenant processing discovers new RANs that contain hardware
associated with that tenant (based on Tenant ID of pathtrace string), the new RAN is assigned
the next sequential "never-been-used" RAN ID, a value from 1-8. If there are no RAN IDs that
have never been used, then Tenant processing will find the least-recently-used RAN ID and
assign that ID to the newly discovered RAN.
The RAN ID is important because it lets the user of the Tenant OAM MIB determine which
RAN corresponds to the RAN-specific MIB parameters, such as:
TenantRanDisableX, TenantRanXForwardMeasuredGain
and
TenantRanForwardGainOffsetX where X is the RAN ID, a value from 1-8.
The RAN ID assignments will be persistently maintained through resets of the Hubmaster
CPU and other CPUs in the network, which will allow the NMS to program the RAN IDs
when new RANs are added to the tenant simulcast group. In the future, the RAN ID
assignments will not be persistent through resets of the network nodes, which will require that
the NMS automatically correlate RAN ID to RAN CPU relationships.
