Configuring Frame Relay SVC Parameters Using the CLI

  1. Each frame relay switch map has a unique ConnectID that is assigned by the system when the switch maps are configured. To find the ConnectID for the SVC you are configuring, use the following CLI command:
  2. CLI> show fr switch map configured table

    You will see a table similar to the following:

    LocalNetIfIndex

    152

    LocalNetDLCI

    100

    ConnectID

    2

    RemoteNetDLCI

    100

    SVCIfIndex

    155

    SVCDNA

    "[x121]302181140042311"

    SVCDLCI

    25

    LocalPVCDLCIState

    active

    SVCUserDLCIState

    ConnectType

    LastChange

    SwitchDisconnReason

    SwitchType

  3. Enter the ConnectID for the SVC for each of the parametersunder CLI Frame Relay SVC Parameters.
  4. CLI> define fr switch svc dna

    Parameter

    Range of Values

    Required Actions

    <ConnectID>

    INTEGER (1..65535)

    Enter the value listed next to ConnectType in the above table.

    <DNA>

    Frame Relay DNA (as a quoted string) (1..34)

    Enter the DNA number (DNA prefix plus suffix) for the SVC of the DLCI.


    Example:

    CLI> define fr switch svc dna 2 "302181140042311"

  5. Save the current configuration and reset the Passport 4400.
  6. CLI> save configuration update

    CLI> reset system current reset

The remaining frame relay SVC parameters are described in the table below:

Options

Description

discardPriority

Indicates the likelihood of frames on this SVC being discarded during periods of heavy congestion. The options are low, medium, and high-discard-level.

dna

The full DNA (including the three-digit suffix) of the destination Passport 4400 for this SVC.

holdingPriority

Specifies the priority this SVC maintains once it is established, as well as the likelihood of its being bumped by a new SVC with a higher priority. A value of 1 is the highest priority, and 5 is the lowest.

maxRxBurstSize

The committed burst size (Bc) in bits per second (b/s) in the ingress direction into the frame relay network. The range is from 0 to 2560000 b/s. If this value is left at 0 (the default), the value configured for the line is used for this SVC. This parameter is used by the system during the negotiation process.

maxRxSize

The maximum frame size in bytes that will be received by the frame relay network from this SVC. The range is from 0 to 4096 bytes. If this value is left at 0 (the default), the value configured for the line is used for this SVC.

maxTxBurstSize

The committed burst size (Bc) in bits per second (b/s) in the egress direction out of the frame relay network. The range is from 0 to 2560000 b/s. If this value is left at 0 (the default), the value configured for the line is used for this SVC. This parameter is used by the system during the negotiation process.

maxTxSize

The maximum frame size in bytes that will be transmitted out of the frame relay network by this SVC. The range is from 0 to 4096 bytes. If this value is left at 0 (the default), the value configured for the line is used for this SVC. For information about how this parameter affects Passport 4400 traffic management, seeTraffic Management.

rxExcessBurstSize

The excess burst size (Be) in bits per second in the ingress direction into the frame relay network. The range is from 0 to 2560000 b/s. If this value is left at 0 (the default), the value configured for the line is used for this SVC. This parameter is used by the system during the negotiation process. This option is not used in the Passport 4400 system.

MaxRxThroughput

The maximum throughput, in bits per second (b/s), used for negotiation of receive data during call setup. The range is from 0 to 2560000 b/s. If this value is left at 0 (the default), the value configured for the line is used for this SVC.

setupPriority

Specifies the priority of an SVC at call-establishment time, and also determines the potential for bumping established SVCs to acquire their bandwidth. A value of 1 is the highest priority, and 5 is the lowest.

txExcessBurstSize

The excess burst size (Be) in bits per second in the egress direction out of the frame relay network. The range is from 0 to 2560000 b/s. If this value is left at 0 (the default), the value configured for the line is used for this SVC. This option is not used in the Passport 4400 system.

txPriority

The relative priority of the traffic on this SVC. The range is from 0 to 15, with higher numbers indicating higher priority. Voice traffic generally has a higher transport priority than data because it has a lower tolerance for delay. The default transport priority for frame relay traffic is 6. For information about how this parameter affects Passport 4400 traffic management, see Traffic Management.

maxTxThroughput

The maximum throughput, in bits per second (b/s), used for negotiation of transmit data during call setup. The range is from 0 to 2560000 b/s. If this value is left at 0 (the default), the value configured for the line is used for this SVC. For information about how this parameter affects Passport 4400 traffic management, seeTraffic Management.
