ZXR10 2900E Series Configuration Guide
l OAM Discovery Function: After enabling Ethernet OAM function, ZXR10 2900E series
switch can detect the remote DTE device which has OAM function. After coordinating
with the peer OAM, enter normal Ethernet OAM interaction process .
l
Remote Link Event Alarm: OAM function inspects the events of remote link, and
adopts the corresponding responding methods. When the fault takes place on re-
mote link, OAM defines the event and announces it to remote OAM client. The de-
tailed events announcement packet is also provided.
OAM defines the following link events.
1. Link Failure: The physical layer locates the failure that take place on receiving
direction of local DTE.
2. Emergency Failure: The local failure event has happened, and this failure can not
be recovered.
3. Emergency Events: The un-defined emergency event happens.
l OAM Remote Loopback: ZXR10 2900E 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 performance. When remote DTE is on the OAM
remote loopback mode, the statistic data of local and remote DTE can be inquired
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).
l
Link Monitoring: ZXR10 2900E 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.
Configuring OAM
The OAM configuration includes the following commands:
Command
zte(cfg)#set ethernet-oam {enable | disable}
zte(cfg)#set ethernet-oam port <portlist>{enable | disable}
zte(cfg)#set ethernet-oam port <portlist> period <1-10> timeout <2-20>
mode {active | passive}
zte(cfg)#set ethernet-oam remote-loopback timeout <1-10>
zte(cfg)#set ethernet-oam remote-loopback port <portlist>{start | stop}
zte(cfg)#set ethernet-oam org-specific {oui <XX-XX-XX>| time-stamp
<1-10>}
