GE port band wide problem

Dear friend!
The maximum bandwidth of an EGS4 port is 1 Gbit/s, and a maximum of six VC-4s can be bound to the EGS4 port. If you bind more VC-4s, resources will be wasted.

now each port config with 8 VC4 but cant get more than 100M and port fix on full duplex 1000 but still band wide still limited on 100M.

Dear friend, have you configured a bandwidth limit?

No any band wide limitation.

Dear friend!

1. Check whether the service configuration is correct, for example, whether the timeslots bound to the two ends are correct. If an exception occurs, reconfigure the service.

2. Perform a ping test to check whether there is packet matching. If yes, check the wiring and other faults.

3. Check whether the interface parameters of the customer device are correctly set.

4. The loopback test or Ethernet frame test can be used to test the Ethernet performance.

5. Use a professional Ethernet test instrument to test the network speed.

6. In addition, query the slot where the board is installed.

For example, the EGS4 board installed on the OptiX OSN 2500. When the EGS4 board is housed in any of slots 5–6 of the subrack, the bandwidth is 622 Mbit/s. When the board is housed in any of slots 7–8 and 11–12 in the subrack, the bandwidth is 2.5 Gbit/s. When the board is housed in slot 13 of the subrack, the bandwidth is 1.25 Gbit/s.

Thanks！

hi ,
1- check the port working mode . it should be 1000M Full Duplex.
2- in some cases the client device needs Electrical SFP to reach 1G .

we checked there is one link and two same GE port for OSN1500 and slot is 2.5G one port is working well and another have some problem we are going to change port to see the result if problem moved when we changing the port it shows client side have some problem for router or switch i will inform you result soon.

OK. Thank you very much for your feedback on the troubleshooting process!
You can use the comparison method to locate the fault by changing the internal and external ports or replacing the board.

Problem solved by changing port we saw problem moved so link is ok then we changed SFP and find one of SFP was faulty and after changing that totally problem solved.
Thanks for all experts for their help and comments.
