This chapter describes the most common configurations for OC3 ports on the Cisco ME 3600X 24CX Series Switch and includes the following sections:
•Configuring Circuit Emulation
•Verifying Interface Configuration
The following limitations and restrictions apply when configuring OC3 ports on the Cisco ME 3600X 24CX Series Switch:
•SDH framing mode is supported.
•SONET mode is not supported.
•HDLC, and PPP, encapsulation are supported.
•Invert data is not supported.
•Frame Relay and SMDS encapsulation are not supported.
•FDL is not supported.
Use the following command to configure the OC-3 ports.
Note On doing no card type T1/E1 0 1, the peer box controller will not go down untill the device is reloaded as prompted.
Use the following command to configure the controller for SDH framing:
The following sections describe how to configure SDH on the OC3 port:
To configure SDH mode, complete the following steps:
There are several standard, but optional, configurations that might be necessary to complete the configuration of your port.
•Configuring the Encapsulation Method
•Configuring the CRC Size for T1
When traffic crosses a WAN link, the connection needs a Layer 2 protocol to encapsulate traffic. To set the encapsulation method, use the following commands:
CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The 4-Port Channelized OC-3/STM-1 IM uses a 16-bit cyclic redundancy check (CRC) by default, but also supports a 32-bit CRC. The designators 16 and 32 indicate the length (in bits) of the frame check sequence (FCS). A CRC of 32 bits provides more powerful error detection, but adds overhead. Both the sender and receiver must use the same setting.
To set the length of the cyclic redundancy check (CRC) on a T1 interface, use these commands:
mtu bytes |
Configures the maximum packet size for an interface in bytes. The packet size range is 64 - 7673. The default packet size is 4470 bytes. |
The following sections describe how to manage interface naming on the Cisco ME 3600X 24CX Series Switch optical interface module.
To specify the physical address for controller or interface configuration, use the interface and controller sonet commands, where:
•slot—Specifies the chassis slot number where the interface module is installed; the slot number is always 1 for interface modules on the Cisco ME 3600X 24CX Series Switch.
•bay—Specifies the subslot where the interface module is installed, the bay number is always 0 for interface modules on the Cisco ME 3600X 24CX Series Switch.
•port—Specifies the OC-3 port number.
For example, if the optical interface module is installed in slot 0 of the chassis, the controller configuration address is specified as controller sonet 1/0/0.
For channelized configuration, the interface address format for t1 is: slot/bay/port.au-3/tug-2/t1:channel-group, the interface address format for E1 is slot/bay/port.au-4/tug-3/tug-2/e1:channel-group where:
•channel-group—Specifies the logical channel group assigned to the time slots within the T1 link.
Interface names are automatically generated, and the format varies based on the line card operating mode.
The listing below shows the formats of the serial interface for each interface type as well as interface formats for HDLC and CEM formats.
Note For HDLC framing, use the serial interface format.
If SDH-AUG mapping is au-3:
•interface serial slot/bay/port.au-3/tug-2/t1:channel-group
BERT (Bit-Error Rate Testing) is used for analyzing quality and for problem resolution of digital transmission equipment. BERT tests the quality of an interface by directly comparing a pseudorandom or repetitive test pattern with an identical locally generated test pattern.
The BERT operation is data-intensive. Regular data cannot flow on the path while the test is in progress. The path is reported to be in alarm state when BERT is in progress and restored to a normal state after BERT has been terminated.
Bit error rate testing (BERT) is supported on optical interfaces. The BERT testing is done only over a framed E1 or T1 signal and can be run only on one port at a time.
The interface modules contain onboard BERT circuitry. With this, the interface module software can send and detect a programmable pattern that is compliant with CCITT/ITU O.151, O.152, and O.153 pseudo-random and repetitive test patterns. BERTs allow you to test cables and signal problems in the field.
When running a BER test, your system expects to receive the same pattern that it is transmitting. To help ensure this, two common options are available:
•Use a loopback somewhere in the link or network
•Configure remote testing equipment to transmit the same BER test pattern at the same time
To run a BERT on an interface, perform the following optional tasks beginning in global configuration mode
The following keywords list different BERT keywords and their descriptions.
Both the total number of error bits received and the total number of bits received are available for analysis. You can select the testing period from 1 minute to 24 hours, and you can also retrieve the error statistics anytime during the BER test.
Note To terminate a BER test during the specified test period, use the no bert command.
You can view the results of a BER 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)

This section provides information about how to configure CEM. CEM provides a bridge between a time-division multiplexing (TDM) network and a packet network, such as Multiprotocol Label Switching (MPLS). The router encapsulates the TDM data in the MPLS packets and sends the data over a CEM pseudowire to the remote provider edge (PE) router. Thus, function as a physical communication link across the packet network.
Note Only 512 pseudowires are supported on the Cisco ME3600X-24CX switch.
The following sections describe how to configure CEM:
Note CEM is used as an element in configuring pseudowires including Structure-Agnostic TDM over Packet (SAToP) and Circuit Emulation Service over Packet-Switched Network (CESoPSN). For more information about configuring pseudowires, see Chapter 7 "Configuring Pseudowire."
The following section describes how to configure a CEM group on the Cisco ME 3600X 24CX Series Switch.
Note You cannot configure the same cem group ID on different controllers.
1. enable
2. configure terminal
3. controller sonet slot/bay/port
4. au-4 au-4# tug-3 tug-3#
or
au-3 au3
5. tug-2 tug-2 t1 t1
6. cem-group group-number {unframed | timeslots timeslot}
7. end
A CEM class allows you to create a single configuration template for multiple CEM pseudowires. Follow these steps to configure a CEM class:
Note The CEM parameters at the local and remote ends of a CEM circuit must match; otherwise, the pseudowire between the local and remote PE routers will not come up.
Note You cannot apply a CEM class to other pseudowire types such as ATM over MPLS.
1. enable
2. configure terminal
3. class cem classname
4. payload-size size
5. dejitter-buffer size
6. exit
7. interface cem 1/0/number
8. cem group-number
9. cem class cem-class-name
10. xconnect peer-ip-address vc-id {encapsulation {mpls}
11. exit
12. exit
The following examples show how to configure a CESoP CEM circuit:
Switch(config)#controller sonet 1/0/0
Switch(config-controller)#au-3 1
Switch(config-ctrlr-au3)#tug-2 1 t1 2 cem-group 3 timeslots 1-24
Switch(config)#int cem 1/0/0
Switch(config-if)#cem 3
Switch(config-if-cem)#xconnect 12.12.12.12 3 encapsulation mpls
Switch(cfg-if-cem-xconn)#end
The following example shows how to configure a SAToP CEM circuit:
Switch(config-controller)#controller sonet 1/0/2
Switch(config-controller)#au-3 1
Switch(config-ctrlr-au3)#tug-2 1 t1 1 cem-group 4 unframed
Switch(config-if)#int cem 1/0/2
Switch(config-if)#cem 4
Switch(config-if-cem)#xconnect 12.12.12.12 4 encapsulation mpls
Switch(cfg-if-cem-xconn)#end
The following sections describe the parameters you can configure for CEM circuits.
•Configuring Payload Size (Optional)
•Setting the Dejitter Buffer Size
Note The CEM parameters at the local and remote ends of a CEM circuit must match; otherwise, the pseudowire between the local and remote PE routers will not come up.
To specify the number of bytes encapsulated into a single IP packet, use the pay-load size command. The size argument specifies the number of bytes in the payload of each packet. The range is from 192 to 256 bytes.
Default payload sizes for an unstructured CEM channel are as follows:
•E1 = 256 bytes
•T1 = 192 bytes
Default payload sizes for a structured CEM channel depend on the number of time slots that constitute the channel. Payload size (L in bytes), number of time slots (N), and packetization delay (D in milliseconds) have the following relationship: L = 8*N*D. The default payload size is selected in such a way that the packetization delay is always 1 millisecond. For example, a structured CEM channel of 16xDS0 has a default payload size of 128 bytes.
The payload size must be an integer of the multiple of the number of time slots for structured CEM channels.
To specify the size of the dejitter buffer used to compensate for the network filter, use the dejitter-buffer size command. The configured dejitter buffer size is converted from milliseconds to packets and rounded up to the next integral number of packets. Use the size argument to specify the size of the buffer, in milliseconds. The range is from 1 to 500 ms; the default is 5 ms.
To shut down a CEM channel, use the shutdown command in CEM configuration mode. The shutdown command is supported only under CEM mode and not under the CEM class.
The following sections describe how to set loopbacks:
•Setting a Loopback on the Controller
•Setting a Loopback at the PDH Level
Note Only one loopback can be configured at conroller level or PDH level across all OC3 ports and PDHs.
To set a loopback on the controller, perform the following task:
You can use the following loopback commands on the controller in global configuration mode:
Note To remove a loopback, use the no loopback command.
Controller level Loopbacks:
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#controll
Switch(config)#controller sonet 1/0/0
Switch(config-controller)#loopback local
PDH level loopbacks:
Switch#configure terminal
Switch(config)#controller sonet 1/0/0
Switch(config-controller)#au-3 1
Switch(config-ctrlr-au3)#tug-2 1 t1 4 loopback network line
Besides using the show running-configuration command to display your Cisco ME 3600X 24CX Series Switch configuration settings, you can use the show interface serial and the show controllers sonet commands to get detailed information on a per-port basis.
To find detailed interface information on a per-port basis on an optical interface module, use the show interface serial and show controllers sonet commands.

For additional examples of the show commands here, see the Cisco IOS Interface and Hardware Component Command Reference.
You can use the following commands to verify your configuration:
•show cem circuit—shows information about the circuit state, administrative state, the CEM ID of the circuit, and the interface on which it is configured. If xconnect is configured under the circuit, the command output also includes information about the attached circuit.
•show cem circuit summary—Displays the number of circuits which are up or down per interface basis.
•show controller sonet slot/bay/port transceiver [status | idprom [brief | detail]]—Displays information about the optical transceiver
•show mpls l2transport vc—Displays the state of local and peer access circuits
•show running configuration—Shows detail on each CEM group
•show xconnect all—Displays the state of the pseudowire and local and peer access circuits
To provide information about system processes, the Cisco IOS software includes an extensive list of EXEC commands that begin with the word show, which, when executed, display detailed tables of system information. .
This section includes the following configuration examples:
