|
SMF Fallback Support Statistics for GTP nodes – Fallback-related counters for SMF provided by AAA, DNS, and local configuration.
In general, an attempt for second SMF or P-GW after the first SMF or P-GW is failed is considered as fallback.
|
|
SMF Fallback Attempted
|
The number of times that fallback is attempted when SMF is preferred. Increments after it fails to connect to the first SMF
and attempts the second SMF. This includes SMFs provided by AAA, DNS, and the local configuration.
|
|
SMF Fallback Success
|
The number of times that a session connected to SMF is selected through the fallback algorithm.
|
|
SMF Fallback Failure
|
The number of times that a session, which is unable to connect to SMF is selected through a fallback algorithm.
|
|
Alternate SMF not found
|
The number of failed attempts to SMF and there is no alternate SMF available to attempt and connect to a session.
|
|
Local SMF resolution
|
Fallback related counters for SMF by local configuration. These counters are not incremented if the first SMF is selected
from the local configuration despite trying to connect to the DNS/AAA provided SMF.
|
|
SMF Fallback Attempted
|
The number of times that fallback is attempted when SMF is preferred. Increments after it fails to connect to the first SMF
and attempts the second SMF. This includes SMFs provided by AAA, DNS, and local configuration.
|
|
SMF Fallback Success
|
The number of times that a session connected to SMF is selected through the fallback algorithm.
|
|
SMF Fallback Failure
|
The number of times that a session, which is unable to connect to SMF is selected through the fallback algorithm. |
|
Alternate SMF not found
|
The number of times that attempts to SMF fail and there is no alternate SMF available for a session to connect.
|
|
P-GW Fallback Support Stats for GTP nodes - Fallback related counters for P-GW provided by AAA, DNS, and local configuration.
In general, an attempt considers as fallback, after failed to connect to the first SMF/P-GW.
|
|
P-GW Fallback Attempted
|
The number of times that fallback is attempted when P-GW is preferred. Increments after it fails to connect to the first P-GW
and attempts for the second P-GW. This includes P-GW provided by AAA, DNS, and local configuration.
|
|
P-GW Fallback Success
|
The number of times that a session connected to P-GW is selected through the fallback algorithm.
|
|
P-GW Fallback Failure
|
The number of times that a session, which is unable to connect to P-GW is selected through the fallback algorithm.
|
|
Alternate P-GW not found
|
The number of failed attempts to all P-GW, and there is no alternate P-GW available to attempt for a session to connect.
|
|
Local P-GW resolution
|
Fallback related counters for P-GW provided by local configuration. These counters do not get incremented if the first SMF
selected from the local configuration gets connected, even after attempting the DNS/AAA provided SMF.
|
|
P-GW Fallback Attempted
|
The number of times that fallback is attempted when P-GW is preferred. Increments after it fails to connect to the first P-GW
and attempts for the second P-GW. This includes P-GW provided by AAA, DNS, and local configuration.
|
|
P-GW Fallback Success
|
The number of times that a session connected to P-GW is selected through the fallback algorithm.
|
|
P-GW Fallback Failure
|
The number of times that a session fails to connect to P-GW and selected through the fallback algorithm.
|
|
Alternate P-GW not found
|
The number of failed attempts to all P-GW, and there is no alternate P-GW available to attempt for a session to connect.
|
|

|
|

|
|
No resource records
|

for the session.
|
|
No matching SMF service params
|
The number of times that the DNS server responded with no SMFs in the resource records, when SMF is the preferred gateway
for the session.
|
|

the session.
|
|
DNS SMF list exhausted
