WEB OPERATION & CONFIGURATION
Tx Frames:
The number of LLDP PDUs transmitted.
Rx Frames:
The number of LLDP PDUs received.
Rx Errors:
The number of received LLDP frames with some kind of error.
Frames Discarded:
The number of frames discarded because they did not conform to the general validation rules as
well as any specific usage rules defined for the particular Type Length Value (TLV).
TLVs Discarded:
Each LLDP frame can contain multiple pieces of information, known as TLVs. If a TLV is malformed, it
is counted and discarded.
TLVs Unrecognized:
The number of well-formed TLVs, but with an unknown type value.
Org. Discarded:
The number of organizational TLVs discarded.
Age-Outs:
Each LLDP frame contains information about how long the LLDP information is valid (age-out time). If no
new LLDP frame is received within the age-out time, the LLDP information is removed, and the Age-Out counter is
incremented.
3.13 EPS
EPS (Ethernet Linear Protection Switching) operation, defined in ITU/T G.8031, is implemented in this device at the
port level. EPS can perform 1+1 and 1:1 switching protection architecture where the former architecture operates
with either unidirectional or bidirectional switching; while the latter one operates with unidirectional switching. It can
also be configured to revertive mode allowing the traffic goes back to working transport entity when the original fault
is repaired and WTR (wait to restore) timer has expired. The other timer supported is Hold-Off timer which configures
the delay time of protection switching until an upstream device or the lower layer is ready for transmission.
In EPS configuration page, EPS instances are created to associate with MEPs on the working and protection entities
that are responsible for sending and receiving APS protocol frames. APS frames can be either unicast or multicast
depending on the types of traffic in the actual networking environment.
EPS ID:
Specify EPS ID for this entry. Click the ID number to further configure detailed EPS settings.
Domain:
Select the flow domain. Currently, only “Port” option is available for use.
Architecture:
The EPS architecture. The architecture at both ends must match.
1+1:
This will create a 1+1 EPS.
1:1:
The APS protocol is mandatory for 1:1 protection.
W Flow:
Working flow instance number.
P Flow:
Protecting flow instance number.
W SF MEP:
Working Signal Failure MEP instance number.
