    Chapter 21 Configuring ATM Connections You can add ATM connections by using either the Cisco WAN Manager Connection Manager or a node’s command line interface (CLI). Typically, the Cisco WAN Manager Connection Manager is the preferred method because it has an easy to use GUI interface. The CLI may be the method of choice in some special cases or during initial node setup for local nodes.

    Virtual Switch Interfaces When a virtual switch interface (VSI) is activated on a port, trunk, or virtual trunk so that it can be used by a master controller, such as a SES PNNI or an MPLS controller, the resources of the virtual interface associated with the port, trunk or virtual trunk are made available to the VSI.

  • Page 375: Vsi Configuration Procedures

    You can assign each VSI interface a default class of service template when you activate it. You can use the switch software CLI or Cisco WAN Manager to configure a different template to an interface. The procedure for adding a VSI-based controller such as the MPLS controller to the BPX is similar to adding an MGX 8220 interface shelf to the BPX.

    When a trunk is added, the entire bandwidth is allocated to Autoroute. To change the allocation in order to provide resources for a vsi, use the cnfrsrc command on the BPX switch. A view of the resource partitioning available is shown in Figure 23-5.

    (LSC or PNNI). Up to three VSI controllers in different control planes can independently control the switch with no communication between controllers. The controllers are essentially unaware of the existence of other control planes sharing the switch. This is possible because different control planes used different partitions of the switch resources.

  • Page 388: Compatibility

    Use of a partition with ID higher than 1 requires support for multiple VSI partitions in both switch software and BXM firmware, even if this is the only partition active on a the card. In a y-red pair configuration, the multiple partition capability is determined by the minimum of the two cards.

    The controller application and Master VSI reside in an external VSI controller (MPLS or PNNI), such as the Cisco 6400 or the MPLS controller in a 7200 or 7500 series router. The VSI slaves are resident in BXM cards on the BPX node.

  • Page 392: Master Redundancy

    When a controller is added to the node, switch software will set up the infrastructure so that the controllers can communicate with the slaves in the node. The VSI entities decide how and when to use these communication channels.

  • Page 393: Vsi Slave Redundancy Mismatch Checking

    You can pair cards with and without the VSI capability as a Y-redundant pair if the feature is not configured on the given slot. As long as the feature is not configured on a given slot, switch software will not perform “mismatch checking” if the BXM firmware does not support the VSI feature.

  • Page 394: What Happens When You Delete A Controller

    When a new controller is added to drive the same partition, the BCC will send a VSI configuration CommBus message with the list of all controllers in the switch, and it will set up the corresponding set of control VCs from the new controller port to each of the slaves.

  • Page 395: How Resources Are Managed

    The maximum number of slaves in a switch is 12. Therefore a maximum of 11 LCNs are necessary to connect a slave to all other slaves in the node. This set of LCNs is allocated from the reserved range of LCNs.

    • MPLS Switching When a connection setup request is received from the VSI master in the Label Switch Controller, the VSI slave (in the BXM, for example) uses the service type identifier to index into a Service Class Template database containing extended parameter settings for connections matching that index.

    Traffic protected by APS 1+1 redundancy is carried via the working line and the protection line simultaneously (see Figure 26-5). Bridging is implemented such that the same payloads are transmitted identically over the working line as the protection line. Cisco BPX 8600 Series Installation and Configuration 26-6 Chapter 26 LM Ð...

  • Page 463: Aps +1 Redundancy Criteria

    The receiver terminating the APS 1+1 has to select cells from either the working or protection line and be able to forward one consistent traffic stream. Since both working and protection line transport identical information, the receiving ends can switch from one to the other without the need for coordinating with the transmit end.

  • Page 464: Application Notes For Aps 1+1

    If the last user request is “clear”, full automatic APS switching is in effect with the working line in the active state by default. When there is no last user switch request to switch any particular line (that is, protection line), the working line becomes active.

  • Page 465: Notes On Switchcdred

    Notes on switchcdred Note In the APS 1+1 configuration, if the last user request was a W –> P switch, then dsplog will log a W –> P switching event when a switchcdred is issued. On a switchcdred, the newly active card comes up on working line first. Then it responds to a user request to switch from working to protection by switching to the protection line and sending an event notification to that effect.

  • Page 466: Aps 1:1 (Line Redundancy)

    Because the protection line is not guaranteed to carry real traffic until the transmit end is informed of the failure and switches, this coordination between the equipment at both ends is more complex.

    When an alarm occurs on the network, the autodial modem automatically dials the specified telephone number. An auto-answer modem at Cisco Customer Service answers the call and directs it to a dedicated personal computer. The alarm is logged under the network ID (an ASCII character string) specified by the network administrator and approved by Cisco Customer Service personnel.

  • Page 484: Chapter 28 Alarm And Statistic

    Cisco WAN Manager collects network statistical data on the operation of the network and stores them in its database. They are available for display on the Cisco WAN Manager console in either tabular form or as bar charts. Statistics can be a useful source of information for troubleshooting problems that do not necessarily cause a major or minor alarm indication or for locating intermittent failures that may occur at random.

  • Page 485: Aps Alarms

    The APS alarms are listed in Table 28-2. The list includes the class or state of the alarm, minor, major, info, or clear. Statistical alarms are not cleared when a YRED switch occurs. You can clear these stats as appropriate. On the active line/trunk, alarms (such as LOS and LOF) and statistics (such as error Note counters) are supported.

    Some of the APS alarms reflect problems with the underlying APS channel protocol, the K1/K2 bytes. The K1 byte carries the request for a switch action on a specific channel to the remote end of the line.

  • Page 508: Unable To Perform Aps External Switch After Forced Or Manual Aps Switch

    APS manual switch to a line does not occur right away Description: You have issued a manual switch either to working or protection line. The switch did not occur because the destination line was in alarm. When the alarm is cleared on that line the switch does occur.

  • Page 509: Aps Switch Made To A Line In Alarm

    Investigation: It is normal operation for a forced switch to cause a switch to a line even though it may be faulty. This enables you to “force” a switch to standby line even if it is in alarm. A traffic outage may occur.

  • Page 510: Aps Switch Occurs Even Though Aps Forced Switch In Effect

    Explanation: Signal Fail on Protection line has higher priority than Forced switch. Whenever the protection line is in failure, there will be a switch to working line, even if the working line is failed or there is a forced W->P in effect.

    Scenario: For an APS 1+1 or APS 1:1 line pair, the port LEDS are the same color on working and protection line. Explanation: To switch software, the APS line pair is a single logical line. Although required to send BXM messages to both lines, these messages will be the same message. Thus switch software cannot send different LED states to the BXM for the same APS line.
