Configuring VCoP Smart SFP
The Virtual Container over Packet (VCoP) smart small form-factor pluggable (SFP) forwards the Plesiochronous Digital Hierarchy
(PDH)/SONET signal transparently across the packet network. VCoP smart SFP is a special type of transceiver which encapsulates
SONET frames on STS-1, STS-3C or STS-12C, and T3 frames on STS-1 channels into a single circuit emulating pseudowire and
transports it to a single destination over Packet Switched Network (PSN).
Note
The VCoP smart SFP feature is supported only on Cisco NCS 4201 and Cisco NCS 4202 Series.
With effect from Cisco IOS XE 16.5.1S Release, VCoP smart SFP supports T3 mode.
Features of VCoP Smart SFP
VCoP smart SFP provides support for the following features:
Supports configuration on Gigabit Ethernet(GE) and TenGigabit Ethernet(10GE) ports of the chassis.
•
OC-3 or OC-12 mode supports 15 km Duplex over GE and 10GE.
•
T3 mode supports 450ft over GE and 10GE.
•
VCoP smart SFP on OCn mode supports 1310nm laser optics and is multi source agreement (MSA) compliant.
•
Supports SONET CEP (IETF RFC 4842).
•
For peer end, supports use of any SFP or interface module that supports CEP protocol.
•
Supports pseudowire configuration.
•
Supports Online Insertion and Removal (OIR).
•
Note
If after configuring a VCoP smart SFP, you remove and reinsert the VCoP smart SFP,
the configuration persists. But, if you insert a non-VCoP SFP, the configuration is
removed.
Supports packetization, de-packetization, and clock recovery.
Ensure that the VC number configured in xconnect command is the same on both PEs.Note

The following parameters affect SONET configuration:
Overhead - Sets the SONET overhead bytes in the frame header to a specific standards requirement, or to ensure interoperability
•
with equipment from another vendors.
J0 - Sets the J0/C1 byte value in the SONET section overhead.
◦
1 byte, 16 bytes, and 64 bytes are the supported values for J0.Note
J1 - Path Trace Byte
◦
C2- Path Signal label
◦
S1S0 - Sets the SS bits value of the H1 byte in the SONET line overhead
◦
Alarm Reporting - Enables reporting for all or selected alarms.
•
B1 - Section BIP Error (SF/SD)

Bit Error Rate Testing (BERT) is supported on VCoP smart SFP at the STS-1 path level. The OCn VCoP hardware does not support
BERT at the concatenated level paths like STS-3c or STS-12c. The interfaces contain onboard BERT circuitry to send and detect a
pattern.
When running a BERT test, your system expects to receive the same pattern that it is transmitting. To help ensure the two common
options are available:
Use a loopback somewhere in the link or network
•
Configure remote testing equipment to transmit the same BERT test pattern at the same time
•
VCoP smart SFP supports Pseudo Random Binary Sequence (PRBS) pattern.
Both the total number of error bits received and the total number of error bits received are available for analysis. You can select the
testing period to be from 1 minute to 24 hours, and you can also retrieve the error statistics anytime during the BERT test.
BERT is supported in two directions:
Line - supports BERT in TDM direction
•
System - supports BERT in PSN direction
•
When the BERT is configured towards system direction, it internally loopbacks the TDM side locally.Note
Configuring BERT on OC-3/OC-12 VCoP Smart SFP
Follow these steps to configure BERT on VCoP STS-1 path for direction as line.
enable
configure terminal

To terminate a BERT test during the specified test period, use the no bert command.Note
You can view the results of a BERT test at the following times:
After you terminate the test using the no bert command.
•
19
After the test runs completely.
•
Anytime during the test (in real time).
•
