  • Network based on CISCO and Microwaves

    Hello, all.
    In some project based on Cisco switches (26/28XX) routers (36/39XX) and microwaves NEC we have a packet losses more than 10%...

    Stages of problem monitoring:
    1. Connecting PC on both sides of microvawe (only a microwave) and checking the network with pinglotter. Network status - OK, packet loss on minimum level of 2 or 3 disconnections for 24 hours of work.

    2. when Cisco is involved in it - we have a lot ot packet losses...

    I think that the problem is that NEC has not a buffer, so when it "busy" it drops the packets.
    So we need to "delay" a packets by cisco...

    Some one is familiar with the problem like this one?

    Thank you.

    Hello,

    Have you checked the port setting's on the Cisco and the Nec. Try to disable auto, and set all to manual, Speed, flow control, duplex.

    Good luck, G.
