no
Disables a previously configured lock on the interface to the NSE/BSC.
peer-nsei id nsei_id
Specifies the numeric identifier of the network service entity mapped to the Gb interface.
nse_id
- Enter an integer from 0 to 65535.
peer-nsei nsei_name
Specifies the name of the NSE associated with the BSC, which is stored in the SCT.
nse_id
- Enter an alphanumeric string of 1 to 64 characters.
Usage
This command allows the operator to lock/unlock the interface, towards the NSE/BSC, based on the NSE
name or NSE identifier.
Lock is configured primarily to avoid the high CPU usage the SGSN can experience when BSCs attempt to
reconnect after an SGSN reboot or reload. The lock stops the auto-learn procedure for the locked BSC
connected via Gb over IP.
The auto-learn facility can be enabled in a staggered manner for each BSC after reboot/reload by unlocking
the BSCs one-by-one.
The NSE unlock state is the default state and the NSE can accept or send any uplink and downlink data.
