I will give an example of setting the trunk port on the EPON ONU connected to the BDCOM OLT.
Suppose a single-port ONU is already connected and registered (228 VLANs without a tag):
interface EPON0/3:7
epon onu port 1 ctc vlan mode tag 228 priority 0
And we need to register several VLANs with a tag, then we will execute:
interface EPON0/3:7
epon onu port 1 ctc vlan mode trunk 1 207,226,228
Where 1 is a VLAN without a tag, since I do not need it, I specified standard 1, and after a space, you can list all the necessary VLANs with the tag.
And also do not forget to specify the desired VLANs on the Uplink and EPON ports of BDCOM:
interface GigaEthernet0/5
switchport trunk vlan-allowed 207,226,228
switchport trunk vlan-untagged none
switchport mode trunk
interface EPON0/3
switchport trunk vlan-allowed 207,226,228
switchport trunk vlan-untagged none
switchport mode trunk
