Management address of MA5626 was connected to the MA5680T failure to be pinged.
Networking: MA5680T—-MA5626 The management entryway address is that the L3 interface address of the OLT.
Handling method
Run the show ont infocommand to examine the standing of the MA5626. The standing is traditional. (activated, online, matched, and normal)
Check the information of the OLT and therefore the MA5626. the information is correct. Replace the VLAN and alter the management information science address. The MA5626 standing is traditional and therefore the management information science address is delivered. However, the ping fails, and therefore the mackintosh entries and Arp entries square measure learned usually.
After a brand new MA5626 is organized, the ping still fails. Therefore, the matter isn't caused by the MxU. Check the OLT configuration once more. The anti-IP attack operate is enabled. when this operate is disabled, the matter is resolved.
MA5626
Root Cause
The MA5680T is organized with anti-IP attack. If this security operate is organized, the device discards the information science packets with the destination address being the device information science address from the user facet. when the ping packet is shipped to the MA5626, the destination information science address within the MA5626 response is that the information science address of the Layer three interface of the OLT, that is, the information science address of the device. Therefore, the device discards the packet. As a result, the ping fails.
Solution
After the anti-IP attack operate is disabled, the matter is resolved.
Suggestions
If this drawback happens, check whether or not some MxUs can not be pinged or all MxUs can not be pinged.
If some MxUs can not be pinged, check the MxU knowledge and device initial.
If all MxUs can not be pinged, check whether or not security policies or ACLs square measure organized on the OLT.t port number: 4)
