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).
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.
Note
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).
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.
Note
•Supports packetization, de-packetization, and clock recovery.
•Supports Explicit Pointer Adjustment Relay (EPAR).
•Supports alarms and performance monitoring.
•Supports loopback and BERT.
•Supports the following jitter buffer values:
◦OC-3 - 8ms
◦OC-12 - 4ms
◦T3 - 8ms
2

•Both OCx and PDH are supported on Cisco NCS 4201 and NCS 4202 Routers.
Benefits of VCoP Smart SFP
•Supports channelization upto STS1 channel
•Reduces network complexity
Prerequisites
•The Multi-Protocol Label Switching (MPLS) and Interior Gateway Protocol (IGP) endpoints are up and running fine between
the PE nodes.
•Ensure that SyncE is configured.
•Use the PTP Telecom profile, G.8265.1 for frequency synchronization, for CEM.
•VCoP smart SFP on OCn mode supports single-mode optical fiber cables.
•Port interface is set as default by using the default int Gig 0/0/8 command before inserting VCoP smart SFP on GE or 10GE
port.
•The GE or 10GE port interface is brought up using the no shutdown command.
•In cases where a non-VCoP SFP is to be inserted on any port from which any VCoP smart SFP is removed, then before inserting
non-VCoP SFP, the VCoP smart SFP configuration is removed using the below commands:
◦For OC-3
no platform smart-sfp interface Gig x/y/z type oc-3
◦For OC-12
no platform smart-sfp interface Gig x/y/z type oc-12
◦For T3
no platform smart-sfp interface Gig x/y/z type ds3
Note •Replace GE with 10GE in the above commands to configure VCoP as 10GE port
interface when inserted in a 10GE port.
•There is no need to remove platform smart-sfp interface Gig/TenGig x/y/z type
oc-3/oc-12/ds3 command if you are replacing one VCoP smart SFP with the same
or another VCoP smart SFP.
•To connect the CE nodes, VCoP smart SFP uses single mode fiber (SMF) over the LC optical interface for OCx mode and DIN
1.0/2.3 Coaxial connector cable for T3 mode.
3

Recommended interfacing connector for the T3 VCoP SFP is Compel 1.0/2.3 Coaxial
connector P/N 350.064.621.
Note
Restrictions
•The payload size is fixed to STS1 and is 783 bytes.
•VCoP smart SFP does not support Stateful Switchover (SSO).
•For QoS, VCoP smart SFP supports only the default MPLS experimental marking.
•At a time, OC-3/OC-12 supports BERT at any one path. T3 supports BERT only at one port.
•VCoP smart SFP does not support E3 mode.
•The chassis supports up to 12 VCoP smart SFPs.
•The T3 mode supports 1 CEP circuit and can sustain the traffic up to 45mbps.
•The Cisco NCS 4201 supports a maximum of 12 VCoP smart SFPs and only on GE ports of the top row.
•The Cisco NCS 4202 supports a maximum of eight VCoP smart SFPs and on all GE and 10GE ports.
•BERT on OCn VCoP is supported only at STS-1 path level. VCoP hardware does not support BERT at concatenated paths.
Alarms on VCoP Smart SFP
VCoP smart SFP supports the following alarms on OC-3 or OC-12 mode:
•Loss of Signal (LOS)
•Loss of Frame (LOF)
•Alarm Indication Signal (MS-AIS, AU-AIS)
•Remote Defect Indication Line (RDI-L)
•Loss of Pointer (AU-LOP)
•Path Unequipped Indication Signal (PUNEQ)
VCoP smart SFP supports the following alarms on T3 mode:
•Loss of Signal (LOS)
•Loss of Frame (LOF)
•Alarm Indication Signal (MS-AIS, AU-AIS)
•Remote Alarm Indication (RAI)

Performance Monitoring and Overhead Bytes
The VCoP smart SFP supports the performance monitoring counter to maintain the path quality of the link.
You can view the statistics or error count generated on the VCoP smart SFP, if you have the configuration that is described:

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)
◦B2 - Line BIP Error (SF/SD)
◦B3 (SF/SD) - STS Path BIP Error
◦sd-ber - Sets Signal Degrade BER threshold
◦sf-ber - Sets Signal failure BER threshold
The performance monitoring result is displayed using the show controller command. The following snippets are the performance
monitoring details when the show controller command is executed.

Running Bit Error Rate Testing
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

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.

•After the test runs completely.
•Anytime during the test (in real time).

Use the show controller command to verify the BERT configuration on VCoP smart SFP.

Loopback on VCoP Smart SFP
VCoP smart SFP supports two types of loopback configurations:
•Local loopback - In local loopback, the transmitting signal is looped back to the receiver signal.
•Network loopback - In network loopback, the receiving signal is looped back to the transmitting signal.
You can configure loopback on VCoP smart SFP at two levels:
