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.
In this mode, the prompt
line should appear similar to:
[<context_name>]hostname<config-if-pvc)#
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.
Privilege:
Security Administrator,
Administrator
Syntax
description textno 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
Example
description “PVC12 connects
server 1 to home office.”
end
Exits the PVC interface
configuration mode and returns to the Exec mode.
Privilege:
Security Administrator,
Administrator
Usage:
Change the mode back
to the Exec mode.
exit
Exits the interface
configuration mode and returns to the context configuration mode.
Privilege:
Security Administrator,
Administrator
Usage:
Return to the context
configuration mode.
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.
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: 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:
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 ip address ip_address
no
Removes the IP address
information for this PVC from the configuration. It is not necessary to

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:
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.
