Hi,
I have a problem in my Huawei s7706 switch. In fact, my s7706 in connected with a trunk interface to the uplink router (Huawei NE40) and directly connected to my CPEs. When i try to do a continuous ping from my CPEs to the s7706 switch, there are some discontinuities in ping flows. I have verified the connectivity (sfp modules, optical cables ..) between my switch and the CPEs and even changed the CPEs. This is strange because i have the same deployment in mayn other sites but the problem is only in this site.
What could be the possible reason for these ping flows discontinuities? Please this is critical because this is one of the Acceptance Tests for the project which consists in doing a continuous ping with mtu size 1500 from one CPE directly connected to the switch.
Here is a photo of my actual deployment. I have configured a management vlan in my switch (vlan 121).
