CTC Operations

This chapter covers Cisco Transport Controller (CTC) operations of the ML-Series card. All operations described in the chapter take place at the card-level view of CTC. CTC shows provisioning information and statistics for both the Ethernet and paket over SONET/SDH (POS) ports of the ML-Series card. For the ML-Series cards, CTC manages SONET/SDH alarms and provisions STS/STM circuits in the same manner as other ONS 15454 SONET/SDH traffic cards.

For information on using CTC to load a Cisco Internet Operating System (IOS) configuration file or to open a Cisco IOS command line interface (CLI) session, see Loading a Cisco IOS Startup Configuration File Through CTC or Opening a Cisco IOS Session Using CTC.

Displaying ML-Series Ethernet Statistics on CTC

The Ethernet statistics window (Figure 2-1) lists Ethernet port-level statistics. The ML-Series Ethernet ports are zero based. Display the CTC card view for the ML-Series card and click the Performance > Ether Ports tabs to display the window. Table 2-1 describes the buttons in the window. Table 2-2 lists the ONS 15454 Ethernet parameters.

Figure 2-1 Displaying ML-Series Ethernet Statistics

Table 2-1 ML-Series Ethernet Statistics Fields and Buttons

Button or Field
Description
Baseline

Resets the software counters (in that particular CTC client only) temporarily to zero without affecting the actual statistics on the card. From that point on, only the delta in counters are displayed by this CTC. These new baselined counters are shown only as long as the user displays the Performance window. If the user navigates to another CTC window and comes back to the Performance window, the true actual statistics retained by the card are shown.

Refresh

Queries the current values from the card and updates the CTC display.

Auto-Refresh

Sets a time interval for the automatic refresh of statistics.

Displaying ML-Series Ethernet Ports Provisioning Information on CTC

The Ethernet port provisioning window (Figure 2-3) displays the provisioning status of the card's Ethernet ports. Click the Provisioning > Ether Ports tabs to display this window. For ML-Series cards, only the Port Name field can be provisioned from CTC. The user must configure ML-Series ports through the Cisco IOS CLI.

Figure 2-3 Displaying ML-Series Ethernet Port Provisioning Information

The Provisioning > Ether Ports tab displays the following information:

•Port Name—Configurable identifier for the port.

•Admin State—Configured port state, which is administratively active or inactive. Possible values are UP and DOWN.

•Link State—Status between signalling points at port and attached device. Possible values are UP and DOWN.

•MTU—(maximum transfer unit) Largest acceptable packet size configured for that port. Default value is 1500.

•Speed—ML1000-2 possible values are Auto or 1Gbps. ML100T-12 possible values are Auto, 10Mbps or 100Mbps.

•Duplex—Setting of the port. ML1000-2 possible values are Auto or Full. ML100T-12 possible values are Auto, Full, or Half.

•Flow Control—Negotiated flow control mode. Possible values are None, Symmetrical, and Asymmetrical.

•Optics—Small form-factor pluggable (SFP) physical media type. Possible values are Unplugged, 1000 SX, or 1000 LX. (This information does not apply to the ML100T-12 card.)

Note Auto indicates the port is set to auto-negotiate capabilities with the attached link partner.

Note The port name field configured in CTC and the port name configured in Cisco IOS are independant of each other. The name for the same port under Cisco IOS and CTC will not match, unless the same name is used to configure the port name in both CTC and Cisco IOS.

Note When set to auto-negotiate, the ML1000-2 might show Auto in the speed and duplex columns of the Ether ports provisioning screen. This indicates that the ML1000-2 is set to auto-negotiate flow control with the link partner. It does not mean the speed or duplex mode of the card will vary from the 1-Gbps, full duplex characteristics of Gigabit Ethernet.

Displaying ML-Series POS Ports Provisioning Information on CTC

The POS ports provisioning window (Figure 2-4) displays the provisioning status of the card's POS ports. Click the Provisioning > POS Ports tabs to display this window. For ML-Series cards, only the POS Port Name field can be provisioned from CTC. The user must configure ML-Series ports through the Cisco IOS CLI.

Figure 2-4 Displaying POS Port Provisioning Information

The Provisioning > POS Ports tab displays the following information:

•Port Name—Configurable identifier for the port.

•Admin State—Configured administrative port state, which is active or inactive. Possible values are UP and DOWN. For the UP value to appear, a POS port must be both administratively active and have a SONET/SDH circuit provisioned.

•Link State—Status between signalling points at port and attached device. Possible values are UP and DOWN.

•MTU—(maximum transfer unit) Largest acceptable packet size configured for that port. Maximum setting is 9000 and default size is 1500 for LEX encapsulation and 4470 for PPP and HDLC encapsulation. The MTU value will display 0 until the POS port is used in creating a circuit.

Note POS interfaces are first created when a CTC STS/STM circuit is provisioned.

Note The port name field configured in CTC and the port name configured in Cisco IOS are independant of each other. The name for the same port under Cisco IOS and CTC will not match, unless the same name is used to configure the port name in both CTC and Cisco IOS.

Managing SONET/SDH Alarms

CTC manages the ML-Series SONET/SDH alarm behavior in the same manner as it manages alarm behavior for other ONS 15454 SONET/SDH cards. Refer to Chapter 7, "Manage Alarms", of the Cisco ONS 15454 Procedure Guide or Cisco ONS 15454 SDH Procedure Guide for detailed information. For information on specific alarms, refer to Chapter 2, "Alarm Troubleshooting", of the Cisco ONS 15454 Troubleshooting Guide or Cisco ONS 15454 SDH Troubleshooting Guide for detailed information.

To view the window, click the Ether Alarming > Provisioning tabs for the Ethernet ports or POS Alarming > Provisioning tabs for the POS ports. Figure 2-5 shows the Ethernet ports alarming pane.

Figure 2-5 Managing ML-Series SONET/SDH Alarms

SONET/SDH Circuit Provisioning

CTC provisions STS/STM level circuits for the two virtual SONET/SDH ports of the ML Series in the same manner as it provisions other ONS 15454 SONET/SDH OC-N cards. For the ONS 15454 SONET, refer to Chapter 6, "Create Circuits and VT Tunnels" of the Cisco ONS 15454 Procedure Guide for a step-by-step procedure for creating ML-Series STS circuits. For the ONS 15454 SDH, refer to Chapter 6, "Create Circuits and Low-Order Tunnels" of the Cisco ONS 15454 SDH Procedure Guide for a step-by-step procedure for creating ML-Series SDH circuits.
