This document describes a sample scenario for connecting a Cisco MGX
8220 shelf to a LightStream 1010 (LS1010) using an ATM User-Network Interface
(UNI) connection. In this example, we are using Frame Relay-ATM Software
Interworking between Cisco routers as the end devices. This can be used as a
general reference for interconnecting other end devices between an MGX 8220
shelf and an LS1010. For more detail on the commands used in this example,
please see the command reference for the respective product.
There are no specific requirements for this document.
This document is not restricted to specific software and hardware
The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.
Technical Tips Conventions for more information on document
Change the BNM cell header format. Note: This will reset the entire
MGX 8220 shelf.
rtp-ax3.1.4.ASC.a > cnfbnmif -if 2
In the above example, we set the cell header format to ATM UNI. The
choices are 1: STI, 2: UNI, 3: NNI. This requires 4.0 firmware or higher on the
MGX 8220 using the E3, DS3, or OC3 BNM cards.
Add the line to the shelf for the FRSM:
rtp-ax3.1.8.FRSM.a > addln 1
Here we are using line 1 from an FRSM-E1.
Configure that line as needed to match your requirements:
rtp-ax3.1.8.FRSM.a > cnfln 1 3 9 2 CCS
We are using a channelized E1 connection using CCS with no CRC4.
Add the port onto the FRSM-8E1:
rtp-ax3.1.8.FRSM.a > addport 1 1 2 2 31 1
We are using port 1 configured on line 1 using channels
Add the channel on the shelf:
rtp-ax3.1.8.FRSM.a > addchan 50 1 100 530000 3
50 = LCN number (will be used again in the LS1010
1 = Port number.
100 = DLCI used by the end device connected to
this port (see 7507 configuration).
5300000 = Frame Relay CIR - ATM traffic shaping
should match this on the LS1010 as well the ATM-attached router. To simplify
the example we made CIR = PCR, but in reality CIR might equal SCR. This depends
on your requirements.
3 = SIW Translate, meaning this is a FR-ATM SIW
connection with translation.

The important part to note in this configuration is the atm pvc command
and the VPI/VCI used on the port connected to the MGX 8220 shelf. The logic is
similar to connecting an MGX 8220 shelf to a BPX, where:
The rx-cttr 10 tx-cttr 10 matches the atm
connection-traffic-table-row index 10 defined above. This traffic
table is defined as UBR with a PCR set to 530 kbytes/sec, which matches the
Frame Relay CIR channel configuration.
In this example, we are using a NP-1A directly connected to the LS1010
via an OC3 connection.

the Frame Relay connection to the MGX 8220 shelf FRSM. For further information,
