Configuring an ATM Interface
A Cisco ASR 1000 Series Aggregation Services Router creates an ATM interface for each T1/E1port that is
configured for the ATM. The interface is in the
atm slot
/
subslot
/
port
format, where
slot
/
subslot
identifies
the SPA slot and subslot, and /
port
identifies the port, for example,
atm 2/1/0
.
The ATM configuration for SPA-24CHT1-CE-ATM is the same as the ATM configuration for
SPA-2CHT3-CE-ATM. For more information about the ATM configuration for SPA-2CHT3-CE-ATM, see
the
Configuring the Card Type for the 2-Port Channelized T3/E3 ATM CEoP SPA, on page 479
.
The SPA-24CHT1-CE-ATM is supported both T1 and E1 modes.
Note
VC QoS on VP-PWRestriction
The VC QoS on VP-PW feature works only with single-cell relay and does not work with the packet-cell
relay function.
Configuring a Pseudowire for an ATM Connection
To configure a pseudowire for an ATM connection, perform the procedure described in the following sections.
The pseudowire carries ATM data across the MPLS network.
Configuring the T3E3 ATM and T1E1 ATM SPAs in the Layer 2 Permanent Virtual Circuit (L2
PVC) Mode
Perform the following steps to configure the T3E3 ATM and T1E1 ATM SPAs with ATM Cell Relay over
Multiprotocol Label Switching (ACRoMPLS) in the L2 PVC mode:

DETAILED STEPS
Purpose
Command or Action
Selects the ATM interface on which the pseudowire has to be configured,
where
slot
/
subslot
is the SPA slot and subslot, and /
port
is the SPA port on
which the interface exists.
