Hi,
I am seeing ICMP duplicates for traffic traversing our virtual chassi (consisting of two ex2300-48p switches).
Physical diagram:
Some findings:
- laptop connected to ge-0/0/9, vlanA = no duplicates
laptop connected to ge-1/0/9, vlanA = duplicates
laptop connected to ge-0/0/9, vlanB = duplicates
laptop connected to ge-1/0/9, vlanB = no duplicates
I ping from the firewall which is the default gateway for both Vlans. We have production traffic in the switches and I haven't heard anything about any issues for them. ICMP duplicates indicates that something is wrong though so I want this solved before it blows up in my face.
The VCP ports are connected with DAC cables.
some outputs:

Anyway to troubleshoot this without changing hardware or firmware?
Thanks in advance
