GBoIP services configured on Ethernet boards (N4EFS0) were not supporting GPRS traffic of the Nokia BSC 660i. Services were configured using VLAN ID (545)
with TAG attributes configured as Hybrid. As a result service was up E2E but during redundancy test, partial traffic got down which should not happen as Ethernet
board was doing Transparent Transmission of the service.
when we performed convergence on end devices NSN BSC switch and CISCO switch ME-3400 ,EFSO board (L-2 switch) start to participate in the convergence process and as result partial traffic got down everytime.
When we assigned VLAN on the interface ports, service was up but when we performed convergence on end devices NSN BSC switch and CISCO switch ME-3400 ,EFSO board (L-2 switch) start to participate in the convergence process and as result partial traffic got down everytime.
To avoid this partial traffic got down issue ,we have disabled Port Entry for both internal and external port in tag attributes of EFSO and service was reconfigured
without any VLAN ID. In this case Traffic was up and redudancy (convergence) also achieved between end devices. EFSO started Transparent Transmission
EFSO board need to do Transparent Transmission between end devices. In this case NSN BSC switch was at one end and CISCO switch ME-3400 was on other end. As we have not tagged Ports so,ethernet board should support transparent transmission traffic between NSN BSC switch and CISCO switch
In case of Transparent Transmission using EFSO borad in Optix OSN3500, Port entry should be disabled while not using VLAN tags on interfaces.
