The following table describes the labels in this screen.
Table 19 EPON Setup
LABEL DESCRIPTION
p2p Access Peer-to-peer (p2p) access allows ONUs on the same port to send packets to each
other directly (without having to route through the uplink ports).
Select the port(s) you want to allow peer-to-peer communication.
Clear the check box to disable this feature. In this case, all packets from the ONUs on
the same port are sent to the uplink interface. ONUs cannot communicate with each
other.
DBA Mode The OLT uses the Plato mode to assign bandwidth dynamically based on the priority
and delay tolerance settings.
You can configure bandwidth settings in the
Profile Setup screen.
Aging Time This is how long all dynamically learned MAC addresses remain in the MAC address
table before they age out (and must be relearned).
Enter a time from 10 to 86400 seconds.
Upstream/Downstream Priority Queue Assignment
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service. Frames without an explicit priority tag are given the default
priority of the ingress port. Use the next two fields to configure the priority level-to-physical queue
mapping.
On the OLT, traffic assigned to higher index queues gets serviced faster while traffic in lower index
queues may be dropped if the network is congested.
