ATM Commands—BlackDiamond 6800 Series Platforms Only
configure atm add pvc
configure atm add pvc <vpi/vci> encap [l2 | ip peer-ipaddress <ipaddress>]
vlan <vlan name> ports <portlist>
Description
This command configures PVC on an ATM port.
Syntax Description
Default
None
Usage Guidelines
Before packets can be forwarded over ATM ports, at least one PVC must be configured on the port and
mapped to a VLAN. Each PVC must be mapped to one or more VLANs and each mapping must be
designated to use the bridged protocol encapsulation or the routed protocol encapsulation. Both
encapsulations can be simultaneously used on a PVC as long as they are associated with different
VLANs.
The PVC is identified by the specified
vpi
and
vci
parameters. The
vpi
parameter is an integer in the
range of 0 through 15. The
vci
parameter is an integer in the range of 17 through 4095. Both
parameters are defined in RFC 2648/1483.
The
encap
parameter indicates the type of encapsulation that is to be used on the PVC for traffic from
the associated VLAN. The
l2
keyword is an abbreviation for Layer-2 and indicates the LLC
Encapsulation for Bridged Protocols (defined in RFC 2684). The
ip
keyword indicates that the VLAN
will carry only routed IP traffic and that the LLC Encapsulation for Routed Protocols (defined in RFC
2684) should be used.
Example
The following command configures PVC 5/101 on ATM port 1:1 on a VLAN named
accounting
.
configure atm add pvc 5/102 encap l2 vlan accounting port 1:1
