PVC Interface Configuration Mode Commands

Mode

The PVC (permanent virtual connection) Interface configuration mode is used to create and manage the IP parameters for PVC interface(s) associated with an OLC (ATM-type) for a specific context.

Exec > Global Configuration > Context Configuration > PVC Interface Configuration

configure > context context_name > interface interface_name point-to-point

Entering the above command sequence results in the following prompt:

[context_name]host_name(config-if-pvc)#
Important:

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

ip

The commands in this section are used to configure the IP parameters for the PVC interface.

Important:

Before configuring the OSPF parameters in this section, you need to enable OSPF using the router command and OSPF configuration sub-mode commands accessed in the Context configuration mode and documented in the Context Configuration Mode chapter of this Command Line Interface Reference.

ip access-group

This command identities the access control list (ACL to be associated with this PVC interface in this context.

Important:

Prior to using this command, the access list must be created for this context with the ip access-list command in the Context configuration mode and then the ACL must be configured using the commands described in CLI chapter ACL Configuration Mode.

Entering the above command sequence results in the following prompt: 

[context_name]host_name(config-if-pvc)#

Syntax

Syntax Description

ip access-group name { in | out } 
no ip access-group name { in | out }

no

Indicates the specified access group to be removed from the access list.

name

Specifies the access control list (ACL) rule to be added or removed from the group.

name: Must be a string of 1 to 79 alphanumeric characters with no spaces.

Important:

Up to 8 ACLs can be applied to a group provided that the number of rules configured within the ACL(s) does not exceed the 128 rule limit for the interface.

in | out

in: Specifies list is for in-bound access control.

out: Specifies the list is for out-bound access control.

Important:

Even though "in" or "out" can be specified, context-level ACL rules are automatically applied to both directions.

Usage Guidelines

Use this command to add IP access lists configured for the same context to an IP access-group. The list can be configured to apply to all inbound and/or outbound traffic.

Examples

The following adds ACL access-list-1 to the IP access-group associated with this PVC for this context. 
ip access-group access-list-1 in

ip address

Defines the primary IP address and the network mask to be associated with this PVC interface for this context. This command can also be used to configure the secondary IP address.

The command must first be issued with the secondary IP address if one exists and then re-issued with the primary IP address.

address ip_address ip_mask

Configures the IP address and the network mask for this PVC interface. The first time this command is entered, it automatically defines the primary IP address for this interface.

ip_address and ip_mask must be specified using the standard IPv4 or IPv6 dotted decimal notation.

secondary

secondary: Including this keyword indicates the IP address and subnet mask being defined are to be used as the secondary IP address for this PVC interface. This is referred to as multi-homing of the interface.

Usage Guidelines

Configures or deletes the IPv4 or IPv6 addresses and subnet mask to be associated with this PVC.

Examples

The following configures the secondary IP address to associate with the interface. 
ip address 131.2.3.4 255.255.255.0  secondary
The following set of commands removes the primary IP address from the PVC interface configuration for this context.
