eNB to DHCP Connectivity Issues Check with DHCP team, if DHCP configuration for that eNB site is done or not DHCP Configuration is done or not
RS_IP for that eNB is configured as per ODD
If eNB OAM plane IP address is configured in DHCP for that eNB or not
Connectivity between DHCP and CSS is established or not
Escalate to RJIL Team for any correction in above steps
If DHCP is able to receive/send any DHCPv6 message with eNB. The DHCP message flow is shown in below figure. If DHCP not receive “Solicit message” from eNB then, follow the troubleshooting in next step.
Troubleshooting at eNB site
Check Connectivity between eNB and CSS (To be done locally at eNB)
Check if cable connectivity, between eNB and CSS, is working properly.
Also, check if port is up at both ends, i.e. at eNB and CSS both, if not then check with CSS team to verify proper functioning of port (shut/no-shut).
If Cable connectivity is found OK. Follow next step, with eNB engineer at the site
To perform troubleshooting, locally at eNB side. Follow below steps
eNB environment parameter setting (check by on field eNB engineer)
Login eNB site locally with root login, and check eNB environment parameters by command “getenv –a”, for PnP grow configuration DEFAULT_VLANID=103
BOOTMODE=dhcp
IPV6_ENABLE=1
DEFAULT_IPVER=64
Troubleshooting at eNB site
lteuser@UAMA:~$ su - Password: ******
root@UAMA:/root>getenv -a [Env Information] DEFAULT_IPVER=64 DEFAULT_VLANID=103 ←OAM VLAN ID BOOTMODE=dhcp ← for PnP Bootmode=dhcp IPV6_ENABLE=1 ←IPV6 Enable=1, Disable=0 __BOOTUP_FLAG__=000000020e
If any discrepancy in above mentioned parameters value, then change them with below process
lteuser@UAMA:~$ su - Password: ******
root@UAMA:/root> root@UAMA:/root>delenv –p BOOTMODE root@UAMA:/root>delenv –p DEFAULT_VLANID root@UAMA:/root>delenv –p IPV6_ENABLE root@UAMA:/root>delenv –p DEFAULT_IPVER
Troubleshooting at eNB site
root@UAMA:/root>setenv –p BOOTMODE dhcp root@UAMA:/root>setenv –p DEFAULT_VLANID 103 root@UAMA:/root>setenv –p IPV6_ENABLE 1 root@UAMA:/root>setenv –p DEFAULT_IPVER 64
To Set environment parameters, use below commands
root@UAMA:/root>cd /mnt root@UAMA:/mnt>rm -rf * rm: cannot remove directory `CPSW': Device or resource busy rm: cannot remove directory `ram': Device or resource busy rm: cannot remove directory `storage': Device or resource busy rm: cannot remove directory `storage_bk': Device or resource busy root@UAMA:/mnt>sync
root@UAMA:/mnt>cd
root@UAMA:/root>reboot
Remove temporary files, sync the memory and reboot
If “authentication request” received then go to next step
Connectivity check between LSM to CSS
Login to LSM-R CLI window and check whether eNB_GW (CSS) IPv6 address is reachable from LSM-R using ping6 command as shown in below figure, Where “DST_IP_ADDR” will be eNB GW IP and “SRC_IP_ADDR” is LSM IP
After getting IPv6 address and RS_IP address, If still eNB is not able to communicate with LSMR then follow below steps.
Troubleshooting from LSM-R
If the eNB is still not reachable then escalate to RJIL data team

Troubleshooting Major GPSR Alarms
Troubleshooting Action:
Check the GPS status in LSM-R CLI window with command “RTRV-GPS-STS”, to check current status of GPS.
Check the GPSR antenna cables installation and cable connection assembly.
Check for any damage/break of GPSR cables. The GPS antenna cable, like all RF cables, should never pulled on, crushed by an over tight strap (cable tie) or stapled. Damaging the cable could result in inconsistent readings over the time, and occasional loss of GPS lock. So check GPS Cable for such tight strap or damages, if found, replace that cable.
Troubleshooting Major GPSR Alarms
Check for water seepage in GPS antenna and or GPS cable.
Troubleshooting Major GPSR Alarms
Check GPSR antenna for any physical damage, if any, replace GPSR antenna.
Check the voltage by multi meter at the Antenna end connector (it should be ~ 5V) & Arrestor (at end side) (it should be around ~5.15V). If there is major difference between the reading, need to correct the connectotization.
Troubleshooting Major GPSR Alarms
Check the location where GPSR antenna is installed. For proper tracking of GPS satellite GPS antenna must be installed at such location
Location that has a clear, unobstructed view of the sky in all directions.
Should be installed on Top of Tower.
There should be minimum distance of 1m between GPSR antenna and other radio antenna installed.
It should not be installed below or back side of Microwave antenna.
Troubleshooting Major GPSR Alarms
Reset the board (UAMA).
Replace the GPS antenna.
Replace the board (UAMA), if still alarm remains (even after checking GPS assembly installation and replacing GPS cables & GPSR antenna).
