Understanding the Service View Tasks Pane in Monitor Mode
The Tasks pane in Monitor mode displays a list of operations that you can perform to analyze and identify network conditions that require corrective action for the configured services on devices. A set of graphs and statistical details in tables are displayed to enable you to easily view the state of your network in an intuitive format. Connectivity Services Director monitors its managed services on devices and maintains the information it collects from the devices in a database. Service View tasks are divided into the following categories in the Tasks pane.
Key Tasks—Connectivity Services Director enables you to group the tasks that you perform frequently and create a list of key tasks. The most preferred tasks that you want to do while using the Service View are listed under Key Tasks. You can add tasks from the service task menu to the Key Tasks category. You can add any task from the Tasks pane to the Key Tasks list by selecting a task and clicking the plus (+) sign that appears adjacent to the task. For some modes, you can see that Connectivity Services Director has predefined some key tasks for you. You can also modify this set of tasks to suit your requirements. This modification feature is available in the Task pane irrespective of your current mode, scope, or view.
Service Summary—Displays the consolidated and cumulative status of a service. This tab is applicable for E-Line, IP, and E-LAN services. The Connections monitor show the status of the connection or link (up or down) between peer devices. In the table displayed for this monitor, the row represents the source device and the column denotes the destination device. The status of the link is displayed for E-Line and E-LAN services. The Traffic Summary monitor represents the total Egress (Packets out) traffic passing through all the UNI or CE interfaces that are part of the cumulative services. It is displayed for E-Line , IP, and VPLS services. The Current Active Alarms monitor shows any active alarm that has not yet been cleared.
Service Transport—Displays the transport or packet statistics for data against time between the source and destination devices that you select, and based on the LSP that is used by the endpoint. The source device is the row selected in the Connection Matrix widget on the Service Transport tab. The destination device is chosen from the Traffic Statistics widget on the Service Transport tab. By default, no destination devices are selected. Service transport statistical values are displayed for E-Line, E-LAN, and IP services.
Service Traffic—Displays the end-to-end traffic matrix that signifies the traffic between peer devices. You can view statistical counters and metrics for input packets, input bytes, output packets, and output bytes. The Interface Statistics monitor shows traffic data on all the user-to-network interfaces (UNI) or site interfaces that are part of the service. These values are on-demand statistical values and the data is retrieved from the device directly without being cached (polling at periodic intervals and displaying a snapshot). This tab is supported for E-Line, E-LAN, and IP services. The data is available only if queues are enabled on the interface.
Y1731—Displays frame delay, frame loss, frame delay variation, and service availability. These measurements are achieved by triggering a one-way delay, two-way delay, or loss The performance measurement is useful for generating periodic service-level agreement conformance reports from the deployed network and for studying traffic patterns in the network over a period of time. In proactive mode, SLA measurements are triggered by an iterator application. An iterator is designed to periodically transmit SLA measurement packets in form of ITU-Y.1731-compliant frames for two-way delay measurement or loss measurement for each of the connections registered to it. Iterators make sure that measurement cycles do not occur at the same time for the same connection to avoid CPU overload. The iterator profiles are configured on remote MEP for measurement of Ethernet frame delay measurement (ETH-DM), Ethernet frame loss measurement (ETH-LM), and statistical frame loss (SFL).
RFC2544—Displays the RFC2544 test profiles created to measure throughput, latency, frame loss rate, and bursty frames. An RFC2544-based benchmarking test is performed by transmitting test packets from a device that functions as the generator or the initiator (which is also called the originator). These packets are sent to a device that functions as a reflector, which receives and returns the packets to the initiator. The test methodology enables you to define various parameters such as different frame sizes to be examined, the test time for each test iteration, and the frame format (UDP-over-IP).
LSP Summary—Displays a comprehensive and cohesive view about the configured RSVP LSP service. The status of the LSP and the status of connections between the ingress router and egress routers in an LSP are displayed. The LSP status details are shown for the ingress router. You can also view the ingress, egress, and transit LSP information, such as the primary and secondary states.
Clear Interface Statistics—Deletes all of the interface-related counters and values associated with the selected service. It is effective for E-Line, E-LAN, and IP services.
Clear LSP Statistics—Deletes all of the interface-related counters and values associated with the selected RSVP LSP service.
MPLS Ping—Sends a probe from one endpoint to the other endpoint of a service, such as E-Line, IP, LSP, and E-LAN. Use the Ping MPLS functionality to diagnose the state of label-switched paths (LSPs), Layer 2 and Layer 3 virtual private networks (VPNs), and Layer 2 circuits. You can ping an MPLS endpoint using various options. You can send variations of ICMP echo request packets to the specified MPLS endpoint.
MPLS Traceroute—Enables you to trace the route followed by an LDP-signaled LSP. LDP LSP traceroute is based on RFC 4379, Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures. This feature allows you to periodically trace all paths in a FEC.
Show Interface Statistics—Displays the interface-related settings and parameters associated with the selected service, such as E-Line, IP, and E-LAN.
Show Interface Status—Displays interface status details to monitor interface bandwidth utilization and traffic statistics associated with the selected service, such as E-Line, IP, and E-LAN.
Show Routing Table—Displays the routing table information for the selected virtual routing instance. For IP services, you can determine which LSPs or tunnels are being used by looking at the routing tables.
Show MAC Table—Displays the learned MAC address information for a device associated with a particular service:
OAM>Y1731—Enables you to start and stop the collection of performance monitoring statistical details.
OAM>RFC2544—Enables you to run RFC 2544 benchmarking tests.
