1. first the port in switch is down, so we check the switch first ,we disable auto-negotiation, and force set speed and duplex manually, after that the port is up, but the 2 device still can't ping each other.
2. after more information, customer said the OLT is in route mode, so it's not because the vlan.
3. in OLT there are some security function, after check the status, we found that they are enabled.
4. we suggest customer to disable these functions.
security anti-ipspoofing enable
security anti-macspoofing control-protocol ipv6oe disable
security anti-macspoofing disable
security anti-ipv6spoofing disable
and indeed, now it is working:
