Description: The number of link down events on the port.
What is cienaCesPmExtendedTxRxHistoryBinLinkDown?
This counts how many times this specific interface's link has dropped out of service. Each increment is this port losing signal, OAM continuity, or its keepalive during this row in the rolling short-interval history table, so it's the first counter to check on this exact interface when a service riding it reported an outage. For example, LinkDown reading 2 for this historical short-interval bin on a port carrying a customer hand-off circuit is enough on its own to open a physical-layer ticket for that link.
