Setting Up Connections Between Other Devices and the RPM

This chapter describes how to make connections between an RPM and a PXM and among either service modules or other RPMs. The chapter contains the following sections:

•Configuring Connections Between the RPM and Other Devices

•Setting Up Connections Between CWM and the RPM

•Setting Up Connections Between Service Modules and the RPM

•ATM Configuration Examples

•Fully Meshed ATM Configuration Example

•RPM-to-Service Module DAX Connections

•RPM-to-PXM Feeder Trunk Connections

•Connection State Alarms

Configuring Connections Between the RPM and Other Devices

After configuring port adapters on the RPM, the user's next step is to configure connections between the RPM and other devices (service modules, other RPMs) via the PXM.

The PXM (the main processor on the MGX 8850) coordinates all communication between the RPM and service modules and other RPMs. See Figure 6-1 for a view of how service modules fit in the MGX 8850.

Figure 6-1 Service Modules in the MGX 8850

A complete connection between the RPM and any of these devices includes two parts:

•Half between the RPM and the PXM.

•Half between the PXM and the service module or a different RPM.

Setting Up the RPM Connection to the PXM

First, set up the connection between the RPM and the PXM.

For the RPM in slot 9 connecting to slot 6, perform the following procedure:

Step 1 Set up a logical interface:

RPM-3(config)# int sw 5/1.1 point-to-point

ip address 1.0.0.1 255.0.0.0

Step 2 Set up pvc:

RPM-3(config-if)# atm pvc 2 0 1 aal5snap

Step 3 To return to the global level, type exit:

RPM-3(config-if)# exit

RPM-3(config)#

Step 4 Enter the rpmrscprtn command to set up resource partitioning

RPM-3(config)# rpmrscprtn PAR 100 100 1 255 0 3840 4080

Partition type [par|tag|pnni] Percent ingress [<0-100>] Percent egress [<0-100>] Minimum 
VPI [<0-255>] Maximum VPI [<0-255> Minimum VCI [<0-3840>] Maximum VCI [<0-3840>] Number of 
LCNs [<0-4080>]

Step 5 Add a connection to the PVC—either VCC (virtual circuit connection) or VPC (virtual path connection):

RPM-3(config)# addcon vcc Switch slot/1[.sub-interface] vci [rname rname] rslot rslot 
r_int r_vpi r_vci [master {local | remote}]

RPM-3(config)# addcon vpc Switch slot/1[.sub-interface] vpi [rname rname] rslot rslot 
r_int r_vpi [master {local | remote}]

Available Parameters

The following parameters are available to set up the RPM to PXM connection.

•slot—RPM slot number

•sub-interface—Optional sub-interface

•vci—Local VCI

•vpi—Local VPI

•rname—Remote nodename

•rslot—Remote slot

•r_int—Remote interface, for example, Switch interface number, or SM port number

•r_vpi— Remote VPI

•r_vci —Remote VCI

•master

–Local makes this RPM the master end of the connection. Type master local to make the local RPM you are configuring master.

Use master local for connections to the PXM or to other SMs, or when connecting to FRSM, PXM for 2- or 3-segment connections. In a local (DAX) RPM-RPM connection, one side must be master.

–Remote (default) makes the other RPM the master end of the connection. Type master remote or press Enter to make the far-end RPM master.

•cost—Maximum connection cost, <1-255> (default 255)

•priority—Routing priority, <0-15> (default 0)

–none—No restriction (default)

–satellite—Avoid satellite trunks

–terrestrial—Avoid terrestrial trunks

•restriction—Restricted Trunk Type

–none—No restriction (default)

–satellite—Avoid satellite trunks

–terrestrial—Avoid terrestrial trunks

•rmcr—Remote MCR value, <0-353208> (default 0; allowed rmcr range will be either <0-rpcr> or <0-0> if rpcr is not explicitly configured)

•rpcr—Remote PCR value, <0-353208> (default 353208)

•rutil—Remote percent utilization, <0-100> (default 100)

•util—Connection percent utilization value, <0-100> (default 100)

Setting Up Connections Between CWM and the RPM

In an MGX 8850 standalone application, you need to set up and configure connections between the Cisco WAN Manager (CWM) and the RPM in order to access and configure the PXM module through the RPM. Do this by adding a connection to the 7.34 port on the PXM.

On the RPM Side

Use the following configuration procedure on the RPM side to set up this connection.

Step 1 Add a sub-interface and provide an IP address and a VPI/VCI.

Step 2 Enter the addcon command to add a connection to the 7.34 port on the PXM and configure this connection as Master.

Note This is the only place that the remote slot number is designated as 7 for PXM.

Step 3 Verify the connection by entering the show switch connection command. The connection should be in sync.

Step 4 Add a static route for the ATM IP address of the PXM pointing to the sub-interface that was added above in Step 1.

Step 5 Verify that the static route exists in the RPM by entering the show ip route command.

On the PXM Side

Use the following configuration procedure on the PXM side to set up this connection.

Step 1 Configure an ATM IP address using the cnfifip command.

Step 2 Verify that the connection added from the RPM is available in the PXM by entering the dspcons command.

Note The LAN IP and IP relay address need to be on different networks.

The connection should be in OK state.

Step 3 Verify that the PXM ATM IP address is accessible from RPM by using the ping command.

Step 4 Add a route on the CWM to the PXM ATM IP address pointing to the RPM Ethernet IP address.

Step 5 ping the PXM ATM IP address from CWM.

You should now be able to access the MGX 8850, MGX 8250, or MGX 8230 shelf from CWM via the RPM.

Setting Up Connections Between Service Modules and the RPM

To complete a RPM-to-service module connection, configure the connection between the service module and the PXM.

Types of Service Modules

Service modules can be of various types, including FRSM (Frame Relay Service Module), AUSM (ATM UNI Service Module), and VISM (Voice Interworking Service Module).

•AUSM—The AUSM-8T1/E1 is a multipurpose card that supports up to 8 T1 or E1 ports.

•VISM—VISM is a multi-DSP, co-processing card and software package that adds voice over IP or voice over ATM AAL2 capabilities to the MGX 8850 platform. The MGX 8850 uses this new feature card along with LAN/WAN routing capabilities to provide a 192/240 channel gateway for VoIP packetized voice traffic to and from TDM traffic.

•FRSM—The FRSM is a two-card set consisting of an FRSM front card (channelized or fractional, T1 or E1, 8 port) and either an 8T1, or 8E1 port adapter back card. The FRSM converts Frame Relay packets into ATM cells. Other FRSMs are available with T3/E3, channelized T3, V.35, X21, and HSSI interfaces of varying supported speeds, depending upon service module type.

•FRSM-VHS—The FRSM-VHS is a two-card set consisting of an FRSM-VHS front card (channelized or fractional, T3 or E3, 8 port) and either a 2T3, 2E3, HS1, HS2 or 2CT3 port adapter back card. The FRSM converts Frame Relay packets into ATM cells.

Data Forwarding to RPMs

Service modules can be configured to forward data to the RPMs in one of two modes: port forwarding or connection forwarding.

FRSM Frame Aggregation: Port Forwarding

In this mode, all frames received on a port are forwarded to the router for L3 processing. For example, a FRSM T1 could be configured for PPP IP access, by doing the following.

1. Setting up a frame forwarding (FF) connection from a FRSM T1 port to the RPM cellbus address on VPI/VCI.

2. Configuring the router to terminate PPP frames forwarded over an ATM connection on the ATM Deluxe Port Adaptor port on VCI 0/xFrame-forwarding (a proprietary method whereby all HDLC frames received on a port are converted to ATM AAL5 frames with a null encapsulation and sent over a single VC). Cisco has already implemented code to terminate frame-forwarded PPP over ATM.

The data flow for a PPP connection destined for the RPM is shown in the figure below. The packet enters the FRSM module as PPP and is frame forwarded to the RPM. The RPM receives the packet in PPP over ATM because MGX 8850 internal connectivity is ATM. The RPM runs software that works with PPP over ATM encapsulation, allowing the router to reach the IP layer and route the packet to its destination (such as the Internet). Packets then destined to the Internet via a WAN network are then sent back to the PXM, and out the ATM uplink.

Figure 6-2 Internal Path of a PPP Packet Destined for RPM

PPP over ATM Example

In this PPP over ATM example, the FRSM is in slot 18 and RPM A is in slot 12. A serial port on Router B is connected to the FRSM line 1.

***

The following is an example of a FRSM configuration. (See FRSM documentation for complete command syntax.)

Step 1 Configure the line.

SQureshi.1.18.FRSM.a> addln 1

Step 2 Configure a frame-forwarding port on the line.

SQureshi.1.18.FRSM.a> addport 1 1 2 1 24 3

Step 3 Configure a frame-forwarding channel from the port to the RPM.

Step 4 Connect DLCI 1000 on the port to a unique VCI on the RPM, using VPI 0.

Connection Forwarding

In this mode, all frames received on a given connection are forwarded to the router using the appropriate ATM encapsulation. For example, Frame Relay connections on a FRSM port could be forwarded to the RPM by

•Translating a Frame Relay connection to an ATM connection or service interworking (FRF.8)

•Configuring DLCI to the RPM cellbus address with VPI/VCI 0/x

•Configuring the RPM to terminate Frame Relay to ATM connections (RFC 1483) on the ATM interface on VCI 0/x

The data flow for a native Frame Relay connection destined to the RPM is shown in Figure 6-3. This data flow is identical to that of PPP packets, but the encapsulation techniques are different. Standard Frame Relay is encapsulated using RFC1490. When a packet is received at the FRSM that has been encapsulated using RFC1490, the standard FR-ATM service interworking translation mode (FRF.8) is performed so that when the packet is forwarded to the RPM it is encapsulated using RFC1483. The router also reads RFC1483, enabling it to reach the IP layer, and route the packet.

Frame over ATM Example

In this example, the FRSM-8T1 is in slot 18 of the MGX 8850, while the RPM is in slot 12.

SQureshi.1.18.FRSM.a> addport 1 1 2 1 24 1

SQureshi.1.18.FRSM.a> xcnfport -pt 1 -sig 3

Step 3 Configure a service-interworking or network-interworking channel from the port to the RPM. Connect each DLCI on the port to a unique VCI on the RPM, using VPI 0.

ATM Service

The ATM UNI Service Modules (AUSMs) provide native ATM UNI (compliant with ATM Forum v3.0 and v3.1) interfaces at T1 and E1 speeds, with eight ports per card, providing up to16 Mbps of bandwidth for ATM service interfaces. This is compliant with the physical and ATM layer, but not with signaling.

Consistent with Cisco Intelligent QoS Management features, AUSM cards support per-VC queuing on ingress and multiple class-of-service queues on egress. AUSM cards fully support continuous bit rate (CBR), variable bit rate (VBR), unspecified bit rate (UBR), and available bit rate (ABR) service classes.

The AUSM-8 cards also support ATM Forum-compliant inverse multiplexing for ATM (IMA). This capability enables multiple T1 or E1 lines to be grouped into a single high-speed ATM port. This
N x T1 and N x E1 capability fills the gap between T1/E1 and T3/E3, providing bandwidth up to
12 Mbps (N x T1) or 16 Mbps (N x E1) without requiring a T3/E3 circuit.

A single AUSM card can provide hot standby redundancy for all active AUSM cards of the same type in the shelf (1:N redundancy).

AUSM modules are supported by standards-based management tools, including SNMP, TFTP (for configuration and statistics collection), and a command line interface. The Cisco WAN Manager application also provides full graphical user interface support for connection management, and CiscoView software provides equipment management.

Table 6-1 summarizes the key attributes of the AUSM cards.

Setting Up the FRSM Connections to the PXM

The following procedure may be used for configuring the FRSM connections to the PXM. The AUSM is slightly different and is in the section "Setting Up the AUSM Connection to the PXM," later in this chapter.

Step 1 Go to the PXM and login.

Step 2 Enter the cc command to go to the slot where the service module is.

8250name.1.slot.FRSM.a> cc 12

Step 3 Enter dsplns to view the line interfaces.

8250name.1.slot.FRSM.a> dsplns

Step 4 To establish the physical connection between the service module and the PXM, enter the addln command to enable a line.

8250name.1.slot.FRSM.a> addln 2

Step 5 Enter the dspports command to display ports.

8250name.1.slot.FRSM.a> dspports

Step 6 Enter the addport command to add a port.

8250name.1.slot.FRSM.a> addport port_num line_num port_type

Step 7 Enter the dspports command to display ports.

8250name.1.slot.FRSM.a> dspports

Step 8 Enter the xcnfport command to choose signaling type.

8250name.1.slot.FRSM.a> xcnfport "-pt" (PortNum) -sig (type)"

<cr>

Step 9 Configure the logical link between the service module and the PXM by entering the addcon command.

8250name.1.slot.FRSM.a> addcon "port dlci cir chan_type [CAC] 
[Controller_Type][mastership][remoteConnId]"

The parameters are

•port number—values ranging from 1-192 are accepted for T1 and 1-248 for E1

•DLCI number—value ranging from 0 to 1023

•committed rate—0-1536000 bps for T1; 0-2048000 bps for E1

•chan type—values 1-5:

–1=NIW

–2=SIW-transparent

–3=SIW-xlation

–4=FUNI

–5=frForward

•CAC—Connection Admission Control (optional); 1 = enable, 2 = disable (default)

•Controller Type (Signaling)—1:PVC (PAR) - Default , 2:SPVC (PNNI)

•mastership—1 for master, 2 for slave

•Remote end Connection ID—Formated as follows:

–NodeName.SlotNo.PortNo.Dlci OR

–NodeName.SlotNo.PortNo.ControllerId.Dlci for FR end point OR

–NodeName.SlotNo.PortNo.VPI.VCI for ATM end point.

Where controller ID can be 1(PAR), 2(PNNI), 3(TAG)

ATM Configuration Examples

The following sections contain examples of ATM interface configurations:

•Example of PVCs with AAL5 and LLC/SNAP Encapsulation

•Example of PVCs in a Fully Meshed Network

For examples of emulated LAN configurations, refer to the MGX 8850 Wide Area Switch Installation and Configuration.

Example of PVCs with AAL5 and LLC/SNAP Encapsulation

The following example shows how PVCs are created on the ATM interface 5/1 using LLC/SNAP encapsulation over AAL5. ATM interface 5/1 (IP address 1.1.1.2 255.255.255.0) connects with the ATM interface (IP address 1.1.1.1 255.255.255.0) at the other end of the connection. The static map list named atm1 declares that the next node is a broadcast point for multicast packets from IP.

Example of PVCs in a Fully Meshed Network

The configurations for RPMs A, B, and C follow. In this example, the RPMs are configured to use PVCs. Fully meshed indicates that each network node has either a physical circuit or a virtual circuit connecting it to every other network node.

Note that the two map-list statements configured in RPM A identify the ATM addresses of RPMs B and C. The two map-list statements in RPM B identify the ATM addresses of RPMs A and C. The two map list statements in RPM C identify the ATM addresses of RPMs A and B.

RPM-to-Service Module DAX Connections

All the configuration examples in the following section illustrate designs where datagrams enter and leave the RPM via the switch interface, get switched on the local PXM, and leave and enter a Service Module on the same MGX 8850 shelf.

RPM-to-FRSM-8T1 ATM/Frame Relay SIW DAX Connection

In this example, IP connectivity is established between a Cisco 3620 router and the RPM blade on the MGX 8850. The T1 WAN interface card (WIC) (serial 0/0) on the Cisco 3620 is connected to physical line 1 on the Frame Relay Service Module (FRSM)-8T1 in slot 11 on the MGX 8850. A digital access and cross-connect (DAX) connection is built through the PXM to switch the cells between the FRSM and the RPM switch interface.

Figure 6-4 RPM-to-FRSM-8T1 ATM/Frame Relay SIW DAX Connection

Configuring the FRSM Interface

This example shows how to configure the FRSM interface, enable the physical line, enable a logical port on the line, and adjust the parameters as necessary.

Configuring the Router Interface

For the router interface, supply the appropriate physical, data-link, and network layer parameters. Because connectivity will be established through Frame Relay/ATM Service Interworking, use Internet Engineering Task Force (IETF) Frame Relay encapsulation on the interface instead of the default Cisco encapsulation, as shown in the following example.

wsw-3620a#conf t

     Enter configuration commands, one per line.  End with CNTL/Z.

Verifying the Configuration

Enter the ping command to verify that you have a good connection.

wsw-3620a#ping 10.97.110.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.97.110.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 24/24/28 ms

Note Because the FRSM defaults to no signaling and the routers default to Gang of Four (also known as Cisco LMI), the two devices will not communicate until they both share the same protocol.

Note You must have encap frame ietf configured on the router before you can have Frame Relay/ATM Service Interworking.

Note The VPI on the RPM switch PVC is always 0.

Note You must match the shaping and policing parameters to prevent data loss.

RPM-to-AUSM-8T1 IMA DAX Connection

For this connection, use the ATM user service module (AUSM)-8T1 card as an Inverse Multiplexing for ATM (IMA) trunk to another AUSM-8T1 card. A connection is built from the RPM on one
MGX 8850 to the RPM on the other MGX 8850 across this IMA trunk.

RPM-to-FRSM-2CT3 ATM/PPP DAX Connection

In the following example, a Cisco 7576 router transmits IPX datagrams out of a channelized DS3 port adapter using PPP encapsulation. The PPP frames are received on an FRSM-2CT3 service module that uses a frame forwarding connection to convert the frames to ATM cells. The cells are received by the RPM on the switch interface, and the datagrams are reintegrated through the aal5ciscoppp encapsulation.

RPM-to-AUSM-8T1/B ATM/ATM DAX Connection

Establish IP connectivity between a Cisco MC3810 router and the RPM blade on the MGX 8850. In the following example, we have configured the Multi-Flex Trunk (MFT) on the 3810 (Controller T1 0) for ATM (logical interface ATM 0). The MFT is connected to the physical line 1 on the AUSM-8T1/B in slot 27 on the MGX 8850. A DAX connection is built through the PXM to switch cells between the AUSM and the RPM switch interface.

Building the RPM Master Connection

The following example shows how to build the RPM master connection.

wsw-8850b-rpm#conf t

     Enter configuration commands, one per line.  End with CNTL/Z.

     wsw-8850b-rpm(config)#addcon vcc switch 1.400 401 rname mgx8850b rslot 27 1 20 400 
master local

     wsw-8850b-rpm(config)#^Z

     wsw-8850b-rpm#cc 7

      (session redirected)

     mgx8850b.1.7.PXM.a > dspcons

     This End        Node Name       Other End       Status

     10.1.0.401      mgx8850b        27.1.20.400     OK

     27.1.20.400     mgx8850b        10.1.0.401      OK

Verifying the Configuration

Enter the show ip ospf neighbor command to view the OSPF-neighbor information on a per-interface basis. Then enter the ping command to verify that you have a good connection, as shown in the following example.

wsw-3810n#sh ip ospf nei

     Neighbor ID     Pri   State           Dead Time   Address         Interface

     10.97.174.1       1   FULL/  -        00:00:34    10.97.172.2     ATM0.400

     wsw-3810n#ping 10.97.172.2

     Type escape sequence to abort.

     Sending 5, 100-byte ICMP Echos to 10.97.172.2, timeout is 2 seconds:

     !!!!!

     Success rate is 100 percent (5/5), round-trip min/avg/max = 36/36/36 ms

Caveats

The following caveats exist.

Note Always check scrambling. Often two ATM devices stop communicating because scrambling is enabled on one device but is disabled on the other.

Note The maximum transmission unit (MTU) sizing default is 4470 on the RPM switch interface and 1500 on the Cisco 3810. A mismatch will cause problems with Open Shortest Path First (OSPF) procedures.

Note On a Cisco 3810 with DVM and MFT, to take the time from the MFT, you must configure the clock source on the DVM to something other than the line; otherwise, clock slips will occur.

Note The VPI on the RPM switch PVC is always 0.

Warning It is necessary to match the shaping and policing parameters to prevent data loss. It is very easy to forget the CNFUPC*** command on the AUSM.

RPM-to-PXM Feeder Trunk Connections

In the configuration examples in this section, datagrams enter and leave an RPM, get switched on the local Processor Switching Module (PXM), and leave and enter through a feeder trunk on the PXM. The BPX 8600, attached to the MGX 8850, switches the ATM cells to either another feeder-attached MGX 8850, ATM-attached customer premises equipment (CPE), or a feeder-attached MGX 8220.

RPM-to-RPM Three-Segment Connection

In the following examples, IP connectivity is established between RPM blades on two different MGX 8850 nodes. A connection is configured on each RPM to the feeder trunk on its associated PXM. Then, a connection is built on the BPX to join the feeder segments.

Configuring the RPM Interfaces

The following example shows how to set the traffic shaping for unspecified bit rate (UBR) at 256000 bps peak cell rate (PCR).

/** WSW-8850A-RPM **/

     wsw-8850a-rpm#conf t

     Enter configuration commands, one per line.  End with CNTL/Z.

RPM-to-FRSM-2E3 Three-Segment Connection

The FRSM uses the service interworking translation method to convert incoming Frame Relay frames to ATM cells. The ATM cells are switched out the PXM interface and switched between feeder trunks by the BPX. When the cells are received by the other PXM, they are switched to the switch interface on the RPM in the node where they are re-integrated back into IP datagrams.

In the example below, IP datagrams are transported through Frame Relay/ATM service interworking between a Frame Relay-attached router and an RPM. An unchannelized E3 port adapter is connected on a
Cisco 7576 router to line 1 on the Frame Relay Service Module (FRSM-2E3) in slot 3 of one MGX 8850.

Caveats

The following caveats exist.

Note Because the FRSM defaults to no signaling and the routers default to Gang of Four (also known as Cisco LMI), the two devices will not communicate until they both share a protocol.

Note The encap frame ietf command is needed on the router for the Frame Relay/ATM Service Interworking.

Note The VPI on the RPM switch PVC is always 0.

Note To prevent data loss, you must match the shaping and policing parameters.

Connection Synchronization

Because connections are added separately to the RPM and to PXM or other RPM cards, connections may exist on the RPM but not on the PXM or the other RPM cards. Therefore, connection synchronization, which is also referred to as service module resynchronization, between the RPM and the other service modules is necessary.

Note This refers to synchronization between the modules' databases, not between the endpoints.

•If connection parameters are mismatched between the two databases, the connection status is set to "MISMATCH." To correct the problem the user is required to delete and re-add the connection.

•Administrative status is not considered as a connection parameter. Therefore, any mismatch in administrative status will not be detected by the connection synchronization feature. The mismatch, however, can be made known by using the OAM loopback test.

•If a connection exists on the RPM but not on a PXM or another RPM, the connection status will be set to "ONLY_ON_RPM." To correct the problem the user is required to delete and re-add the connection.

•If connection exists on a PXM or another RPM, but not on the local RPM, the connection status will be set to "NOT_ON_RPM." To correct the problem the user is required to delete and re-add the connection. The connection on the other service module can be deleted by issuing "no switch connection" on the RPM as if the connection exists on the RPM.

Manually Resynchronizing Connections

You can manually resynchronize connections. However, out of synchronization conditions may be triggered by

•Periodic kickoffs

•Connection provisioning time-out on the RPM

•PXM switchover

•RPM reset

You can force resynchronization by entering the start_resynch command at the configure interface level as shown here:

NY_9# conf t

NY_9(config)# int sw1

NY-9(config-if)#switch start_resynch

Automatically Resynchronizing Connections

auto_synch corrects mismatches between the PXM and the RPM databases. If your network is highly unstable, do not turn on auto_synch.

The commands that are used to enable/disable the auto_synch feature are moved under the new switch command. Here is an example of how you use this command on the config level.

NY_9# conf t

NY_9(config)# int sw1

NY-9(config-if)#switch auto_synch on <off|manual> "default is off"

Connection State Alarms

This section describes the alarm state of each PNNI, how alarms occur, and what they mean.

Endpoint status indicators reported by RPM and their meanings include:

•egrAisRdi—The endpoint is receiving AIS or RDI cells in the egress direction (from the network).

•ccFail—An OAM loopback failure has occurred.

•mismatch—There is a mismatch between the RPM and Connection Manager databases.

•conditioned—There is a routing failure.

These alarms are triggered when

•There is a change in the endpoint status.

•If a failure is detected by the Connection Manager during a routine routing status check.

Connection State Resynchronization

Connection state resynchronization is triggered by a PXM-1 switchover or an RPM reset. This happens when an alarm state is not persistent nor contains redundant data, and needs to be rebuilt after a switchover or reset.
