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
