PVC Interface Configuration Mode Commands


PVC Interface Configuration Mode Commands
 
 
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.
All configuration information specified with these commands is displayed using the Exec mode.
 
Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
 
description
Defines descriptive text to provide useful information about the current interface.
Product

Syntax
description text
no description
no
Erases the port’s description from the configuration file.
text
text: must be a string of 1 to 79 alphanumeric characters with no spaces or a string within double quotes that includes printable characters. The description is case-sensitive.
Usage
Set the description to provide helpful information, for example the port’s primary function, services, end users. Define any information, the only limit is the number of characters, 79.
Example
description “PVC12 connects server 1 to home office.”

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.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
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 is a string of 1 to 79 alpha and/or numeric 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
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.
Example
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.

Privilege
Security Administrator, Administrator
Syntax
ip address ip_address ip_mask [ secondary ]
no ipaddress ip_address
no

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.

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