Procedure for Restoring the ont ipconfig Configuration

 Step 1    On the MA5616, change the mask to 255.255.255.0.

MA5616(config)#interface vlanif 901
MA5616(config-if-vlanif901)#ip address 10.PPP.10.126 255.255.255.0

 Step 2    On the OLT, delete the ont ipconfig configuration.

OLT(config-if-gpon-0/7)#undo ont ipconfig 0 12

   Step 3    Configure ont ipconfig on the OLT again. The mask is still 255.255.255.0. The following uses slot 1, port 12, and ontid 1 as an example.

OLT(config)#interface gpon 0/1
OLT(config-if-gpon-0/1)#ont ipconfig 12 1 static vlan 901 ip-address 10.110.10.126 mask 255.255.255.0 gateway 10.***.10.1

   Step 4    Delete the ont ipconfig configuration on the OLT. The following uses slot 1, port 12, and ontid 1 as an example.

OLT(config-if-gpon-0/1)#undo ont ipconfig 12 1

    Step 5    Configure ont ipconfig on the OLT again. Change the mask to 255.255.254.0. The following uses slot 1, port 12, and ontid 1 as an example.

OLT(config-if-gpon-0/1)#ont ipconfig 12 1 static vlan 901 ip-address 10.***.10.126 mask 255.255.254.0 gateway 10.***.10.1

OLT(config-if-gpon-0/1)#quit

   Step 6    After the preceding operations are complete, save the configuration on the MA5616 for subsequent possible configuration restoration.

MA5616(config)#save
