Ping test from EMAS

EMAS can be also used for UP ping tests

Ping test from EMAS

Add CP address and Execute

Traceroute Command$ traceroute <IP address>This command is useful to trace the IP route from

one node to a destination IP address. In case of routing issues (ARP table corruption, server down, ...) traceroute makes it easier to find the exact point of disconnectivity.

NTP AlarmSample of NTP alarm occur on RBS

Action: Check the NTP server address is correct Ping check from RBS to NTP Server Restart ET-MFX board Plug-unplug Ethernet port Plug-unplug ET-MFX board Replace ET-MFX board

Troubleshooting GuideFollow ALEX documentation for clearing any

alarm occur on the node.Escalate to next level support if the

alarm/problem still occur.
