3. OAM Remote Loopback
ZXR10 2900 series switch provides optional data link layer
frame level loopback mode by OAM function.
OAM remote
loopback is used to locate failure and examine the link per-
formance. When remote DTE is on the OAM remote loopback
mode, the statistic data of local and remote DTE can be in-
quired and compared at any time. Meanwhile, OAM loopback
frame can be analyzed to obtain the additional information of
link health (frame discard due to the link failure).
4. Link Monitoring
ZXR10 2900 series switch monitors and examines the link
state, and announces the specified frame events by OAM
function.
The specified frame events can be classified into
four types: error symbol period event, error frame event and
error frame period event, error frame-second statistic event.
After inspecting the error, OAM will respond and alarm the
peer device by announcement mechanism.
