| Description | The ATM Cell layer stats table is for the cell layer over
a physical line. There is an entry for each SONET, DS3 or
DS1 line. The table maintains objects that apply to ATM
end-systems, as well as objects that apply only to ATM
switches.
In all the following descriptions of objects,
CLP-0 means Cell Loss Priority = 0, and
CLP-1 means Cell Loss Priority = 1.
ATM cells with CLP=0 have a higher priority in regard to cell
loss than ATM cells with CLP=1. Therefore, during resource
congestions, CLP=1 cells are dropped before any CLP=0 cell is
dropped.
Ingress direction means coming from network to the switch.
Egress direction means going from switch to the network. |
