By default, on all ONUs of any manufacturers that are connected to the BDCOM OLT, the maximum speed is set to 100 Mbps, in order to increase it, you must specify a pair of commands for a specific ONU.
Let’s say you have a registered ONU:
show running-config interface epon 0/1:5 interface EPON0/1:5 description ixnfo.com epon onu port 1 ctc vlan mode tag 735 priority 0 epon onu port 1 ctc loopback detect
Now let’s allow this ONU a maximum speed of up to 1 Gbps:
interface EPON0/1:5 epon sla upstream pir 1000000 cir 10000 epon sla downstream pir 1000000 cir 10000 exit
Let’s save the configuration:
If you do not change pir and cir, then their default values (100 Mbps):
pir 100000 cir 1000
PIR – Peak Information Rate
CIR – Committed Information Rate
CIR is calculated from the total bandwidth of the EPON port, so it cannot be increased much, as this may affect the speed of other ONUs, I also do not recommend using these commands as a shaper, it is better to limit the speed to clients somewhere up to BDCOM, I use them only when after the ONU there is a managed switch or when the client has a tariff of more than 100 Mbps.
Also, some ONUs may support rate limiting on the ethernet port, I will give an example:
epon onu port 1 ctc rate-limit 150100 ingress epon onu port 1 ctc rate-limit 150100 egress
