Severity: 3-Major


Quota provided by the 2nd Gy CCA-u is ignored which can result in limiting the effective quota provided to a subscriber. This in turn can result in additional control plane traffic as additional Gy CCR-u's outlining quota threshold/exhaustion will be sent by PEM.


Potential service hit and increase in control plane traffic.


PEM with Gx and Gy sessions. The threshold against the provided quota should be a large percentage of the quota which would result in quota exhaustion before additional quota is provided by the OCS.


Mitigation: Configure the threshold to be a smaller percentage of the provided quota.
