2xGigE/FC-P2P WAN port signal attributes
Signal Attribute Definition
LCAS Link Capacity Adjustment Scheme
(Link Capacity (applicable to virtual concatenation only).
Adjustment Scheme)
SCRAMBLE Enables X^43 +1 scrambler.
(Scramble)
NCP Indicates the Network Control Protocol
(Network control used.
protocol)
LANFCS Indicates whether the LAN FCS is
(Encapsulated included in the encapsulated frame (for
frame) both the ingress and egress direction).
(See Note 6) ENABLE indicates the LAN FCS is
included.
RTDELAY Round trip delay (in microseconds). Only
(Round trip delay) available when mapping is GFP-F or
GFP-T.
Note 1: Values in bold indicate defaults.
Note 2: R/O = Read Only, R/W = Read & Write (provisionable).
Note 3: For MAPPING=GFP-F or GFP-T, only possible value is ENABLE.
Note 4: For MAPPING=GFP-F possible values are 0 or 32. For MAPPING=GFP-T, only possible value is 0.
Note 5: If another WAN port is already created, the VCAT attribute defaults to the value of the existing WAN port.
Note 6: You must edit the mapping protocol, frame check sum size, magic number and link connectivity monitor
attributes at the same time. The system rejects any invalid combination of values for these attributes.

Ethernet Operational Measurements

The Ethernet Operational Measurements collected by the 2xGigE/FC-P2P
circuit packs can be divided into two groups:
•
•
OPTera Metro 3500 Multiservice Platform
Generic Interface Operational Measurements (based on the Interfaces
Group MIB, RFC 1213, RFC 2233, RFC 2863).
— Applies to all types of interfaces:
– LAN (Ethernet, Fibre Channel)
– WAN (GFP)
Ethernet Specific Operational Measurements (based on RFC 2665
Ethernet-Like MIB).
— Applies to Ethernet interfaces only.
