I have problems with the OSFP, having two switch MS-425 in Stack and two Switch MS-350 in stack. My connection is as follows, the MS-425 stack connects to the MS-350 stack via Fiber Optics. when I ping from PC 01 to PC02 there is a loss of packets and if I ping from PC02 to PC01 there is also a loss of packets Any idea what could be the problem. I attach the image detailing the connection
Is this a 100% loss of packets?
Are the two machines in the same vlan or different vlans?
Are the ports connecting the switches together configured as trunk ports?
The Packet Loss are 75-80%
The Machines are in different Vlans
The Port are Access because the Fibre optic is the ISP. The path is Layer 2 MPLS.
I don´t believe than is the path, the packet loss only occurs between the clients. The interesting thing is that if I replace the MS-350 for the old Switch(Alcatel) it doesn´t present any packet loss. Also it doesn´t present anything about CRC or physical errors.
What is the VLAN number and default gateway IP address for PC01.
What is the VLAN number and default gateway IP address for PC02.
Can the switches ping betweem themselves ok?
