PVC Configuration Mode Commands


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.
 
Important: The commands or keywords/variables that are available are dependent on platform type, version, and installed license(s).
 
bind
This command binds IP interface or 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.

Security Administrator, Administrator
Syntax
bind { interface interface_name context_name | link ss7-routing-domain rd_id linkset-id id link-id id}
no bind { interfaceinterface_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
bind ss7-routing-domain 1linkset-id 23link-id 2
 
encapsulation aal5
Specify the data encapsulation type for the ATM adaptation layer 5 (AAL5) frames for the PVC.
Product

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
encapsulation aal5 vc-mux
 
end
Exits the PVC configuration mode and returns to the Exec mode.

exit
Exits the PVC configuration mode and returns to the ATM port configuration mode.

Usage
Return to the port configuration mode.
 
shaping
Specify the type of traffic shaping (rates) for this PVC.

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
shaping cbr pcr 56000
 
shutdown
Disables/enables traffic over the current VLAN.
Product

Privilege
Security Administrator, Administrator
Syntax
shutdown
no shutdown
no
Enables the VLAN. When omitted the VLAN is shutdown.
Usage
Enables/ Disables specified port or card. Command action depends on mode issued from.hut down a 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
