3 1 INTRODUCTION The IPe-422 is Advantech s latest offering for video and IP content distribution. Available as standalone or in conjunction with AMT-75 DVB-S2 modem product line, the IPe-422 is a single board embedded platform supporting IP Encapsulation, MPEG TS from ASI inputs and IP multiplexing, PIDs filtering and routing, and much more. The purpose of this document is to provide a quick installation guide for configuring the IP Encapsulator (IPE) functionality for use of embedded IPe-422 with AMT75 modems or as a standalone. 2 CONFIGURATION STEPS There are a number of steps necessary to configure the IPE. These steps are outlined below: Enable IPE Configuring LAN interface (Ethernet) Configuring IP routes Creating DVB MPE interface Configuring mapping on the DVB MPE interface Configuring channels on the DVB MPE interface Configuring other DVB MPE options Configuring IP routes 2.1 Enable IPE In order to enter administration mode user must enter enable in the console when the IPE finish initilazation. 2.2 Configuring LAN Interface (Ethernet) With regards to the IPe-422, four 10/100BaseT interfaces are supported (port numbers 1-4), Ethernet port number 5 should not be used for now. To configure these interfaces, use the following commands at the IPe-422 prompt configure terminal interface Ethernet 0 Enters global configuration mode Command creates interface if it does not exist and starts interface configuration mode 3

4 ip address A.B.C.D/M Assigns an IP address and subnet mask to the interface (A.B.C.D/M IP address with mask): is 0 bits (used for an explicit route for a single IP address) is 24 bits (used for a C- Class Mask) is 16 bits (used for a B- Class Mask) is 8 bits (used for an A-Class Mask) Command shutdown shuts down the interface. Command starts interface working. In the sample listing above Ethernet interface was created, IP address with mask prefix length 24 ( ) was added and after that interface was started by invoking command. If the IPE needs to be managed on a VLAN environment, then a VLAN ID can be set as follows: configure terminal interface Ethernet 0 interface Ethernet 0.1 encapsulation dot1q [1-4095] ip address /24 Enters global configuration mode Command creates interface if it does not exist and starts interface configuration mode Command shutdown shuts down the interface. Command starts interface working. Command creates a subinteface to the Ethernet to support the VLAN ID. Provides Ethernet encapsulation mode in support of IEEE 802.1Q VLAN with range Assigns an IP address and subnet mask to the interface (A.B.C.D/M IP address with mask) Command starts interface working. In the sample listing above Ethernet interface was created, VLAN ID of 10 and associated IP address with mask prefix length 24 ( ) was added and after that interface was started by invoking command. 4

5 Additional commands are available to control Ethernet functions. These include the following, however, in this Quick setup guide, they will be defaulted. mac-address 00:0e:12:34:56:78 Command is used to configure MAC address on the interface. By default vendor defined MAC address is configured. The interface settings may be displayed at the base command prompt by entering the following: show interface ethernet 0 Command is used to configure MAC address on the interface. By default vendor defined MAC address is configured. The following would be the typical display: Interface Ethernet0, Index 3, MTU = 1500, Metric 0, BW Kbit CDP disabled on this interface Status (admin/proto/port) = (up/up/up) UP BROADCAST RUNNING MULTICAST IP address /24 broadcast minute input rate bits/sec, 2251 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec Input packets, bytes, 0 errors Output 5382 packets, bytes, 0 errors Multicasts sent 0, received Input queue is fifo: 0 drops, 0 "no proto" Output queue is fifo: 0/2000/0 (size/max/drops) Encapsulation protocol is ARPA address is 022E A ARP cache TTL 0, down-dont-send time 0, prune interval 0, retries number 0 Port type is Gigabit Ethernet, mode Generic Ethernet Receive errors: 0 short, 0 giant, 0 non-octet 0 bad CRC, 0 overrun, 0 in range error 0 bad alignments, 0 out of range, 0 pause frames Send errors: 0 underrun, 0 late collisions, 0 aborts 0 retries, 0 retransmit limit Packets: 5381 transmitted, received Interrupts: 624 output, input, 0 events 5

6 2.3 Configuring transmit rate When the IPE is integrated into the AMT75 modem, the egress speed configuration is provided by the modem logic. As such, no additional configuration is required. The stream is defaulted 188bytes framing mode. When IPE is standalone the following demonstrate rate configuraion: configure terminal dvb-mpe txrate rate-value Enters global configuration mode Configuration of the output MPEG-TS rate. 2.4 Configuring DVB MPE Interfaces DVB Multiprotocol Encapsulation interface is require for the IP to MPE encapsulation process configure terminal interface serial 0 ip address a.b.c.d ip unnumbered Ethernet 0 Enters global configuration mode Associates the interface to the internal AMT75 port Configuration of ip address to the interface is require only in case of local traffic sending to the baseband. Optional. IP addess of Ethernet 0 will be used as source address for local traffic sent to baseband interface. Optional. Command starts interface working. 2.5 Configuring Channels on the DVB MPE Interface DVB Multiprotocol Encapsulation is implemented through mechanism of logical channels. Each channel defines a MAC address, PID, and other parameters such as QOS. configure terminal Enters global configuration mode 6

7 interface serial 0 Associates the DVB MPE interface dvb-mpe channel 0 mac-address mac-value pid pid-value qos-class qos-class-name Establish a logical DVB channel to associate MAC/PID and Ip information For Unicast, this is typically the MAC address the route is assigned to and is determined by the end device (nexthop) to which the data is sent. All MPE packets transmitted through this channel will have this PID value. PID range is Command defines Quality of Service Class for channel. QOS can be setup to setup guaranteed bandwidth channels using command sets similar to those normally associated to Frame relay. For instance, parameters such as Committed burst Bc, Excess burst Be, and Committed Information Rate (CIR) may be defined to fix bandwidth or establish a ceiling for guaranteed bandwidth to individual channels. Traffic destined for the channel may be allocated high, medium, or low priority. Only one PID and one MAC address may be associated to a particular channel, though many channels may be established to support different traffic types to a particular destination. 2.6 Configuring Mapping on the DVB MPE Interface Mapping rules associate destination IP address (or group of addresses) with specified channel. The same channel may be specified in more than one mapping rules. Use the following command for defining mapping rule.. dvb-mpe map-entry A.B.C.D or A.B.C.D/M channel-number Command associates single IP address or range of IP address with mask to channel number defined Note a Unicast route will fall within the range to (excluding broadcast or reserved IP addresses), and a multicast route will fall within the range of to Configuring Other DVB MPE Options Default channels for broadcast and multicast packets may be defined either as per mappings IP address ranges above or by using specialty commands: dvb-mpe default-broadcast-channel channel-num Command associates single IP address or range of IP address with mask to channel number defined 7

8 dvb-mpe default-multicast-channel channel-num dvb-mpe section-packing Command associates single IP address or range of IP address with mask to channel number defined Enables section packing to improve efficiency of IP over MPEG. dvb-mpe asi 1 mux-input-enabled Enable multiplexing of ASI input 1 into the IPE output MPEG-TS stream. dvb-mpe asi 2 mux-input-enabled dvb-mpe asi 1 input-pid PID-Value dvb-mpe asi 2 input-pid PID-Value Enable multiplexing of ASI input 2 into the IPE output MPEG-TS stream. By default the IPE forward all MPEG TS traffic from ASI 1 input, this command filter only required PID from the stream. Packets with other PID s will be dropped. By default the IPE forward all MPEG TS traffic from ASI 2 input, this command filter only required PID from the stream. Packets with other PID s will be dropped. dvb-mpe asi 1 mux-output-enabled Enable ASI interface output 1. dvb-mpe asi 2 mux-output-enabled Enable ASI interface output Configuring IP Routes IP routes must be configured on the router for providing IP packets forwarding rules. By default router "does not know" what packets must be forwarded on the DVB Multiprotocol Encapsulation Interface (Serial 0). Example below demonstrates IP routes configuring procedure. ip route /0 interface serial 0 Command creates a default static route which directs all IP traffic to the serial interface (configured in next section). 8
