The functions of the Connection Capacity Validation feature are described in Validating Diameter Connection Capacity. On the GUI page, the current Connection configuration capacity information for configured active DAMPs displays.
You can perform these tasks on an active System OAM (SOAM).
Each row on the page contains the information for one configured active DAMP.
The
page is view-only and has two tabs.The Connections Table tab contains information about the currently configured Connections for each DAMP in the NE. Fixed Connections and Floating IPFE Connections displays with Floating IPFE Connections grouped by Target Set.
The Connection Reserved Ingress MPS Table tab contains the currently configured Reserved Ingress MPS for each DAMP in the NE. The contribution of both Fixed Connections and Floating IPFE Connections displays with Floating IPFE Connections grouped by Target Set.
Note:
The Connection Capacity Dashboard does not use field coloring; usage values at or in excess of 100% are not flagged by cell coloring.It is theoretically possible for this usage value to exceed 100%; diameter does not prevent over-configuration in certain scenarios (typically involving overlapping Target Sets, or a non-overlapping Target Set whose DAMPs have significantly different numbers of Fixed Connections assigned). For a given DAMP, if the number of Connections allocated to that DAMP exceeds the DAMP's Maximum Connections count capacity (from the assigned MP Profile), the Current Connection Usage (%) value exceeds 100%.
This usage value is computed as the sum of Reserved Ingress MPS values for a DA-MP's Fixed Connections and Floating IPFE Connections, divided by the Maximum Reserved Ingress MPS value.
It is theoretically possible for this usage value to exceed 100%; diameter does not prevent over-configuration in certain scenarios (typically involving overlapping Target Sets, or a non-overlapping Target Set whose DAMPs have significantly different numbers of Fixed Connections assigned).
The maximum connections value assigned to the DAMP in the MP Profile.
For a given DAMP, the value displayed in the # Fixed Connections field should never exceed the Connection Capacity.
If a DAMP has one or more configured Fixed Connections, then the value appears as a hyperlink. The hyperlink opens the
page, filtered to show only the Fixed Connections assigned to the DAMP.The value displayed for a given DAMP and Target Set is the evenly-distributed allocation of Floating IPFE Connections to each DAMP in the Target Set. If the evenly-distributed allocation value is zero, then the value zero displays in the field.
The evenly-distributed allocation of Floating IPFE Connections is zero if there are more DAMPs in the Target Set than Floating IPFE Connections configured for the Target Set. In this case, to make it clear DAMP is part of the Target Set, the value zero displays (instead of a blank field).
If a DAMP has no IPFE allocation for a defined Target set, the corresponding field is blank.
It is theoretically possible for this usage value to exceed 100%; diameter does not prevent over-configuration in certain scenarios (typically involving overlapping Target Sets, or a non-overlapping Target Set whose DAMPs have significantly different numbers of Fixed Connections assigned). For a given DAMP, if the number of Connections allocated to that DAMP exceeds the DA-MP's Maximum Connections count capacity (from the assigned MP Profile), the Current Connection Usage (%) value exceeds 100%.
This usage value is computed as the sum of Reserved Ingress MPS values for a DAMP's Fixed Connections and Floating IPFE Connections, divided by the Maximum Reserved Ingress MPS value shown in the fourth column of the Connection Reserved Ingress MPS Table tab.
It is theoretically possible for this usage value to exceed 100%; diameter does not prevent over-configuration in certain scenarios (typically involving overlapping Target Sets, or a non-overlapping Target Set whose DAMPs have significantly different numbers of Fixed Connections assigned).
If the total Connection Reserved Ingress MPS for Connections allocated to a given DAMP exceeds the DAMP's scaled Engineered Ingress MPS, the Current Reserved Ingress MPS Usage (%) exceeds 100%
Note:
There is one exception – a system already configured with Fixed Connections having some non-zero Total Fixed Connection Reserved Ingress MPS value. If the Connection Reserved Ingress MPS Scaling is decreased, thus decreasing the scaled Engineered Ingress MPS on every DAMP in the system, it is possible the new lowered Maximum Reserved Ingress MPS is less than the already-configured Total Fixed Connection Reserved Ingress MPS.If a DAMP has no Fixed Connections assigned to it, then the corresponding field shows a value of zero.
Note:
The IPFE GUI does not require Target Sets to be configured sequentially. For example, you can define Target Sets 4, 11, 12, and 32. The Dashboard page always shows only the configured Target Sets, from the smallest configured number to the largest configured number.The value displayed for a given DAMP and Target Set field is the evenly-distributed allocation of Floating IPFE Connections' Reserved Ingress MPS to each DAMP in the Target Set. If the evenly-distributed allocation value is zero, then the value zero displays in the field.
The evenly-distributed allocation of Floating IPFE Connections is zero if all of the Floating IPFE Connections configured for the Target Set have Reserved Ingress MPS values of zero. In this case, to make it clear DAMP is part of the Target Set, the value zero displays (instead of a blank field).
If a DAMP has no Floating IPFE allocation for a defined Target set, the corresponding field is blank.
If a DA-MP has one or more Floating IPFE Connections allocated to it for a given Target Set, the value is displayed as a hyperlink. When clicked, the page opens, filtered to show only those Floating IPFE Connections assigned to the Target Set. Because Floating IPFE Connections are not configured to a particular DAMP, this filtered display cannot show a DAMP allocation; it instead shows all Floating IPFE Connections in the Target Set.
The Connection Reserved Ingress MPS Scaling value, from the page, is the percent of DAMP Engineered Ingress MPS used by each DAMP when validating the Reserved Ingress MPS for a newly received Floating IPFE Connection. A newly received Floating IPFE Connection is rejected if the total Connection Reserved Ingress MPS for Fixed Connections and already established Floating IPFE Connections would exceed the DAMP's Engineered Ingress MPS, scaled by this value.
