Issue Description
Our Network is:
UA5000(IPMA) -- Metro1000 -- Metro3000 -- Metro5000 -- BRAS(MA5100)
UA5000 cannot connect to BRAS
Alarm Information
Request timeout, when ping from IPMA to BRAS and vice versa
Handling Process
- IPMA configuration at UA5000 is verified as per plan. Correct VLAN and routing configuration.
- EFS configuration(EP-LAN) at Metro1000 is verified as per plan. correct VLANs and payloads assigned.
- EFS configuration(EP-LAN) at Metro3000(Transmission) is verified as per plan .Correct the transmission payloads assigned at EFS card and correct the VLAN configuration with VCTRUNKS of EFS card.
- EG2S configuration at Metro5000 is checked and also found that VLANs assigned at EGS2 card were correct but binded to wrong VCTRUNKS
VLAN configuratiuon of EGS2 is modified and VLANs are added to correct VCTRUNK and payloads.
Root Cause
VLANs are added in wrong VCTRUNK and with wrong payloads.
Suggestions
While adding VLANs at EFS or EGS2 cards at transmission end, we should double check whethher the are binded with correct payloads or not otherwise service
will not up and its hard to diagnose this fault
