DuraMAR 2150 – User’s Manual Chapter 3 System Operation This chapter illustrates the operation of the Eurotech Communication Controller (ECC) and its interaction with the CISCO 3200 ISR. If not otherwise stated, hereafter the word “system” will implicitly refer to ECC subsystem only. Overview The ECC is a standard x86-based system running a Linux kernel and a preinstalled application software (hereafter referred to as ECC firmware).
DuraMAR 2150 – User’s Manual DuraMAR-2150 configuration The configuration of DuraMAR-2150 system involves the configuration of the CISCO 3200 ISR and ECC subsystems. • The CISCO 3200 ISR subsystem can be configured using the console interface available on the panel side under the removable protection cover. The serial communication parameters must be set to 9600N81 (9600 baud, No parity, 8 bit data size, 1 Stop bit). There is no username or password defined in the default configuration.
DuraMAR 2150 – User’s Manual Configuration Mode The Configuration Mode is used to configure the system. This mode provides two sub-modes of operation: Global or Specific, depending on what part of the system the user is configuring. Specific mode allows access to the configuration area of one of the system components, hardware or software, while Global mode allows access to global configuration parameters affecting the whole system.
DuraMAR 2150 – User’s Manual As another example, the following commands: HSDPA-rt(config)# route 192.168.10.0 255.255.255.0 via 10.11.3.1 HSDPA-rt(config)# no route 192.168.10.0 255.255.255.0 will first set up a static route and then remove it. Using commands history The CLI stores a history of commands that you have entered. This feature is particularly useful for recalling long or complex command or entry strings.
DuraMAR 2150 – User’s Manual Network interfaces general configuration To configure a network interface the user must enter the Specific Configuration Mode for the given interface by issuing the interface if-name command while in Configuration Mode. The prompt will change accordingly. For example: HSDPA-rt(config)# interface hsdpa0 HSDPA-rt(config-if-haspa0)# The list of available interfaces can be obtained by issuing the show interface command.
DuraMAR 2150 – User’s Manual 5. nat enable 6. enable 7. exit 8. exit Please note that the exit command must be issued twice. An example of a Router Mode configuration follows: Version: 1.0.0 - $Rev: 317 $ ! hostname HSDPA-rt interface eth0 ip address 172.16.10.1 255.255.255.252 enable ! interface hsdpa0 ip address negotiated enable apn web.omnitel.
DuraMAR 2150 – User’s Manual Dynamic Bridge Mode In Dynamic Bridge Mode the carrier-assigned public IP address is made available to the CISCO 3200 ISR FastEthernet interface using the DHCP-protocol; then the first (.1) or last (.254) IP address of the network that this address belongs to is automatically assigned to the ECC Ethernet interface in order to guarantee local IP-connectivity. For example if the carrier assigns 114.22.34.
DuraMAR 2150 – User’s Manual Commands reference The following table lists the available commands for configuring the HSDPA interface: description Adds a text description for the interface mtu Sets the IP Maximum Transmit Unit (MTU) tcpmss Forces the TCP maximum segment size for the sessions entering or exiting from the interface defaultroute The interface will be used as default gateway apn network_name Defines the Access Point Name (APN) for the PDP context username username Username to use dur
DuraMAR 2150 – User’s Manual HSDPA interface information The current status of the HSDPA interface can be retrieved using the show interface hsdpa0 command in User Mode: HSDPA-rt# show interface hsdpa0 Interface hsdpa0 is Enabled physical status is PPP Hardware type is HSDPA modem Network in use : HSDPA Cat. 6 (3.6Mbps) IP address is 91.80.172.179 255.255.255.
DuraMAR 2150 – User’s Manual The relevant fields in the output of this command are: Temperature The internal temperature of the ECC HSDPA module System mode GPRS (2G) or WCDMA (3G) GMM and MM state NORMAL SERVICE or LIMITED SERVICE RCC_STATE The registration status, CELL_DCH, CELL_FACH, DISCONNECTED (for 3G networks only) RX level The quality of the signal received by the module SNMP configuration The system can be monitored using the SNMP protocol. Only SNMP version 2c is supported.
DuraMAR 2150 – User’s Manual Limiting remote access to the system Access to the system by connecting through the gprs0 interface can be restricted to a list of specific IP addresses. There are no limits to the number of IP addresses in the list. By default there is no access restriction. By issuing one or more set admin-ip ip-address commands the user can restrict the access to only the given IP addresses. The no-form of the command removes the permission.
DuraMAR 2150 – User’s Manual Log files Important events are logged on the flash memory. User can view the logged messages using the show log system command. Because the size of the flash memory available for the log file is limited, the size of the log file is checked periodically and, if it increases to more than 3MB, it is automatically resized to the last 1000 messages. At any moment user can clear the log file using the delete log configuration command.
DuraMAR 2150 – User’s Manual If needed the upgrade process can be performed manually with the following steps. First the new firmware image must be downloaded, verified and saved to the flash memory. This can be done using the download image command. This command will download the new image, check it’s correctness and save it to the flash memory.
DuraMAR 2150 – User’s Manual Installing a new firmware using the DuraMAR USB-disk key Whenever the system doesn't boot as expected (for example in case some system file has become corrupted or unreadable) or whenever a new fresh installation is required, the user can install the firmware by using the provided USB-disk key. This operation is not intended be performed as routine maintenance but only in case of serious problems.
DuraMAR 2150 – User’s Manual Using the integrated CISCO router for hosting controller system image files. Downloading a new image might be quite difficult if the ECC is configured to operate in Bridge Mode. In this configuration the HSDPA interface can’t be used by the ECC itself so users, setting the appropriate static routes, must download the new image from a remote host through the slow GPRS interface or from a local host connected to the CISCO Ethernet interface.
DuraMAR 2150 – User’s Manual DuraMAR-2150 service interface A GPRS modem is included as part of the DuraMAR-2150 system in order to provide a diagnostics and backup/emergency connection to the system in the event that the HSDPA link fails. This GPRS modem has a serial interface and can be connected through a software-controlled switch either to the AUX interface of the CISCO 3200 ISR or to the ttyS1 interface of ECC using a software command or an SMS command message.
DuraMAR 2150 – User’s Manual The commands are represented by the text of the SMS message. Available commands: SERCPU Connects the GPRS modem serial interface to ECC ttyS1 interface SERCISCO Connects the GPRS modem serial interface to the AUX port of the CISCO 3200 ISR RESETCPU Force a hardware reset of ECC. RESETALL Force a complete system reset with power-off/power-on cycling.
