egtp-pathfail ecm-idle rate ecm-connected rate
Configures the UE deactivation pacing rate for MME S11/S10/S3 interfaces (any EGTPC service with
interface type “interface-mme”).
interface type “interface-mme”).
ecm-idle rate
: This keyword defines the deactivation rate for UEs in ECM Idle mode.
ecm-connected rate
: This keyword defines the deactivation rate for UEs in ECM Connected mode.
rate
specifies a rate threshold in sessions per second per session manager (SessMgr) as an integer from 1
through 5000.
Note: Configuring a high deactivation rate can have a negative effect on performance. Appropriate
dimensioning exercises should be performed to arrive at the optimum rate.

enb s1-paging rate
Configures an S1 paging rate limit applicable to all eNodeBs connected all MME services. S1 Paging
requests to an eNodeB will be rate limited at this threshold value. S1 Paging requests to an eNodeB
exceeding this threshold will be dropped.

rate
specifies the rate threshold in messages per second per eNodeB as an integer from 1 through 65535.
Usage
