We just installed a new circuit from the telco and we are noticing packet loss whenever we do a stress test. (ping x.x.x.x source x.x.x.x repeat 3000 size 1500 data 0000). We are seeing about 5-8 packet being lost. Telco troubleshooted and made a change to the incoming cables from 2 wire to 4 wires. As per them they are not seeing any errors when tested anymore. We replaced the cables, and card on the router, and checked the DSU.
What we did notice if we input a mtu size of 1490 on the config the test is fine, however configuring mtu size is not company standard. We also have other sites with similar config as well as router model and they are fine. According to telco they are not aware of any mtu setting on their end, therefore they cannot make a change related to mtu.
For now we don't want to break company standard and configure mtu size, but as far as testing and obtaining no packet loss this is the only thing we could come up with that's giving us favourable results.
Any ideas on this little dilema would be greatly appreciated.
