LABEL DESCRIPTION
IEEE 802.3ah Ethernet OAM Click this switch to enable or disable the Ethernet OAM on the specified interface.
When the switch goes to the right , the function is enabled. Otherwise, it is not.
Interface Select the interface on which you want to enable the IEEE802.3ah.
OAM ID Enter a positive integer to identify this node.
Auto Event Click this switch to detect link status and send a notification when an error (such as
errors in symbol, frames, or seconds) is detected. Otherwise, disable this and you will
not be notified. When the switch goes to the right , the function is enabled.
Otherwise, it is not.
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.
