Features
Select
Variable Retrieval
so the Zyxel Device can respond to requests for
information, such as requests for Ethernet counters and statistics, about link events.
Select
Link Events
so the Zyxel Device can interpret link events, such as link fault and
dying asp.Link events are set in event notification PDUs (Protocol Data Units), and
indicate when the number of errors in a certain given interval (time, number of
frames, number of symbols, or number of error frame seconds) exceeds a specified
threshold. Organizations may create organization-specific link event TLVs as well.
Select
Remote Loopback
so the Zyxel Device can accept loopback control PDUs to
convert Zyxel Device into loopback mode.
Select
Active Mode
so the Zyxel Device initiates OAM discovery, send information
PDUs; and may send event notification PDUs, variable request/response PDUs, or
loopback control PDUs.
