# PVC Configuration Mode Commands

The Permanent Virtual Connection (PVC) configuration mode commands bind IP interfaces or SS7-Frame Relay links a PVC as well as configure PVC operational parameters for a specific port.
In this mode, the prompt line should appear similar to:

    [local]hostname(config-port-<slot#>/<port#>-pvc-<pvc_num>/<vci_num>)#

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, version, and installed license(s).
bind

This command binds an IP interface or an SS7 link to the PVC.

IMPORTANT:

Prior to attempting the binding, the interface and context or the SS7 routing information and link must have been configured.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    [ no ] bind { interface interface_name
    context_name | link ss7-routing-domain rd_id linkset-id id link-id id }

no

Removes the binding from the configuration.
interface_name

Defines the name of the virtual interface to be bound to the PVC. interface_name: Must be a unique string consisting of 1 to 79 alphanumeric characters.
context_name

Specifies the name of the context to be bound to the virtual interface. context_name: Must be a unique string consisting of 1 to 79 alphanumeric characters.
ss7-routing-domain rd_id

Identifies a specific SS7 routing domain. rd_id must be an integer from 1 to 12
linkset-id id

Identifies a specific linkset within the routing domain. id: must be an integer from 1 to 33
link-id id

Identifies a specific link within the linkset. id: must be an integer value 1 - 16
Usage:

Use this command to bind the PVC to an interface or a specific link.

Example

Example
Use a command similar to the following to bind a PVC to a link ID #2:

    bind ss7-routing-domain 1 linkset-id 23 link-id 2

encapsulation aal5

Specify the data encapsulation type for the ATM adaptation layer 5 (AAL5) frames for the PVC.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    encapsulation aal5 { llc-snap | vc-mux }

llc-snap

Frames protocol is identified in the AAL5 using logical link control (LLC) encapsulation.
vc-mux

Frames are not encapsulated and use virtual circuit multiplexing (VC-MUX) to identify the protocols used for the AAL5 frames.
Usage:

Use this command to identify the protocol type for the circuit.

Example

Example

    encapsulation aal5
    vc-mux

end

Exits the PVC configuration mode and returns to the Exec mode.
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    end

Usage:

Change the mode back to the Exec mode.
exit

Exits the PVC configuration mode and returns to the ATM port configuration mode.
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    exit

Usage:

Return to the port configuration mode.
shaping

Specify the type of traffic shaping (rates) for this PVC.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    shaping { cbr
    pcr prc_num | ubr pcr prc_num | ubr+ pcr prc_num mrc mrc_num | vbr pcr prc_num scr src_num mbs mbs_num }

cbr

Constant bit rate

pcr - peak cell rate = cells per second

prc_num: Must be an integer from 75 to 1412830
ubr

Unspecified Bit Rate

pcr - peak cell rate = cells per second

prc_num: Must be an integer from 75 to 1412830
ubr+

Unspecified Bit Rate with Minimum Cell Rate.

The PCR and MCR values should be set to maintain the following relationship: PCR >= (MCR + minRate), where the current recomment minRate is 75.

pcr - peak cell rate = cells per second

prc_num: Must be an integer from 75 to 1412830

mcr - minimum cell rate

mrc_num: Must be an integer from 75 to 1412830
vbr

Variable Bit Rate, NRT (not real time) type.

The PCR and MCR values should be set to maintain the following relationship: PCR >= (MCR + minRate), where the current recomment minRate is 75.

pcr - peak cell rate = cells per second

prc_num must be an integer from 75 to 1412830

scr - sustained cell rate

src_num must be an integer from 75 to 1412830

mbs - maximum burst size

mbs_num must be an integer from 75 to 1412830
Usage:

Use this command to configure the shaping for egress traffic on this PVC.

Example

Example

    shaping cbr pcr 56000

shutdown

Disables/enables traffic over the current VLAN.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    shutdownno shutdown

no

Enables the VLAN. When omitted the VLAN is non-functional.
Usage:

Enables/ Disables specified VLAN.

This command is necessary to bring a VLAN into service by enabling it via the no keyword.
Example:
To disable a VLAN from sending or receiving network traffic use the following command:

    shutdown

To enable a VLAN use the following command:

    no shutdown
