ZTE C620 OLT MAC addresses on ports

Hello,

Would it be possible to add display of MAC addresses on port on a ZTE C620 OLT? 

The output of snmpwalk looks like this:

.1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1.31.285279233.0.1.208.126.40.43.116.235 = STRING: d0:7e:28:2b:74:eb
.1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1.31.285279233.0.1.212.1.195.29.109.12 = STRING: d4:1:c3:1d:6d:c
.1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1.4000.285278465.268501248.3.0.235.216.90.187.180 = STRING: 0:eb:d8:5a:bb:b4
.1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1.4000.285278465.268632320.3.140.144.45.54.190.176 = STRING: 8c:90:2d:36:be:b0

.1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1 is the base OID (ZTE-AN-MAC-MIB::zxAnMacFwdVlanMacAddr)

Next is the vlan (in this case 31 or 4000)

After that is interface ID.

After that it's either 0 for non-gpon interfaces or onu service ID for gpon interfaces. 

ONU vport ID is made up like this (ZxAnSubIfIndex):

2 - ONU vport sub-interface
|      MSB      |    Byte 2    |    Byte 1    |    LSB     |
|--------------------------------------+-----------|
|     2     |       ONU No.    |   VPort No.  |     0      |
|  (5bits)  |      (11bits)    |   (8bits)    |  (8bits)   |
-------------------------------------------------+

after that its the type of MAC entry - 

1 - dynamic
2 - permanent
3 - static

After that it's the MAC address.

So, .1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1.31.285279233.0.1.212.1.195.29.109.12 = STRING: d4:1:c3:1d:6d:c
can be decoded as such:

vlan 31, interface id 285279233, type dynamic, address d4:1:c3:1d:6d:c

.1.3.6.1.4.1.3902.1082.40.10.2.1.5.1.1.4000.285278465.268632320.3.140.144.45.54.190.176 = STRING: 8c:90:2d:36:be:b0
can be decoded as such:
vlan 4000, interface 285278465, vport 1/1/1.3:1 (ONU 1/1/1:3, vport 1), type static. address 8c:90:2d:36:be:b0

I can attach larger SNMP walks if needed.
