Support for Cisco 500 Series WPAN Industrial Routers (IR500)

The IR500 series connects to DA devices using serial ports (RS232/RS485) and/or an Ethernet port using IPv4. The IR500 series provides remote connectivity to serial DA devices over CG-Mesh by transporting serial data over TCP/IP. The IR500 series also provides remote connectivity to IPv4 DA devices over the IPv6-based CG-Mesh by using Mapping of Address and Port using Translation (MAP-T). The IR500 series performs NAT44 translation to translate private IPv4 addresses used by DA devices connected to the Ethernet port to public IPv4 addresses used with MAP-T.

Support for CG-DM 4.1

The 4.1 release of Device Manager adds support for the IR500 series WPAN, in addition to support for the CGR 1000 running Cisco IOS.

Device Manager connects to the IR500 directly over the laptop COM port, either with or without a work order. Device Manager displays IR500 hardware status and allows you to configure and view settings for MAP-T, TCP raw socket, WPAN, RPL, and other protocols used by the IR500 in the CG-Mesh network.

Support for CG-NMS 2.1.1

The 2.1.1 release of CG-NMS adds support for the IR500. CG-NMS manages the IR500 as a mesh endpoint device.

You can also create work orders in CG-NMS that authorize a remote Device Manager to configure and manage the IR500.

Virtual WPAN (VWPAN) Interface

VWPAN provides the architecture for providing 802.1X and Mesh-security services to partner-developed module and mesh endpoints.

Refer to Documentation Updates.

Dynamic Multipoint VPN (DMVPN)

DMVPN is a Cisco IOS Software solution for building scalable IPsec Virtual Private Networks (VPNs) such as hub-spoke deployments.

http://www.cisco.com/c/en/us/support/security/dynamic-multipoint-vpn-dmvpn/tsd-products-support-series-home.html

Industrial Operations Kit (IOK)

IOK is a Cisco software solution that simplifies Cisco Field Area Network (FAN) deployment by automating the configuration of multiple network and security management system components as individual virtual machines within the Cisco Unified Computing System (UCS) server.

The kit includes a single headend router, bundled with Cisco PRIME Access Registrar software for authentication, authorization and accounting, and the Connected Grid Network Management System with Cisco Embedded Services Routers for zero-touch deployment.

Support for Cisco 819 Integrated Services Router

The Cisco 819 Integrated Services Router Family, designed in compact hardened and non-hardened form factors, is the smallest Cisco IOS Software router with support for integrated fourth-generation (4G LTE) wireless WAN (mobile broadband backhaul) capabilities. The Cisco 819 ISR gateway provides a rapidly deployable, highly available, reliable, and secure solution designed specifically for machine-to-machine (M2M) applications.

The following hardened Cisco 819 ISR PIDs are supported beginning in Cisco IOS Release 15.5(1)T1: C819HG-4G-V-K9, C819HG-4G-A-K9, C819HG-U-K9, C819HGW-S-A-K9, and C819H-K9.

This release expands support to include the following non-hardened Cisco 819 ISR PIDs: C819G-B-K9, C819G-U-K9, C819G-4G-V-K9, and C819G+7-K9.

■Determining the Software Version

■Upgrading to a New Software Release

■Erasing the Configuration File

Determining the Software Version

To identify the software version operating on the Cisco IOS router, enter the following command:

Upgrading to a New Software Release

The software image is a bundle image and includes the following components: Cisco IOS image, Guest OS, Hypervisor, and a Virtual Device Server. When you initiate installation of the software, all of the components automatically install on virtual machines with the router.

To install a new version of software, you copy the bundle image over to flash and issue the bundle install command to upgrade the software.

router# bundle install flash:cgr1000-universalk9-bundle.SSA.154-0.99.05.CG

You will then see output similar to the following:

Installing bundle image: /cgr1000-universalk9-bundle.SSA.154-0.99.05.CG...

updating Hypervisor image...

Sending file modes: C0444 22931642 cgr1000-hv.srp.SPA.0.30

updating IOS image...

Sending file modes: C0644 73830734 cgr1000-universalk9-mz.SSA.V154_0_99_05_CG

Done!

After the software installation bundle finishes and displays Done! on the screen, enter the following commands to save the configuration and complete the installation process on the router:

router# copy running-config startup-config

router# reload

Erasing the Configuration File

command, it erases a specified item or initiates an action to save memory on the Cisco 1000 Series router. See specifics in write erase command.

Table 3 write erase command

Command

Purpose

write erase {/all nvram: } /no-squeeze-reserve-space file-system : | file-system : | startup-config

/all –Erases all files in the specified file system.

nvram –Erases all files in the NVRAM.

file-system : –File system name, followed by a colon. For example, flash: or nvram:.

This argument may not be used if the device memory contains logging persistent files.

/no-squeeze-reserve-space –Disables the squeeze operation to conserve memory and makes the erase command compatible with older file systems.

startup-config –Erases the contents of the configuration memory.

Limitations and Restrictions

Cisco recommends that you review this section before you begin working with the router. These are known limitations that will not be fixed, and there is not always a workaround for these issues. Some features might not work as documented, and some features might be affected by recent changes to the CGR 1000 router hardware or software.

A write on c3gGsmRoamingPreference results in commit failed."

SNMP write on most of ciscoWan3gMib is not supported for security reasons.

When you issue snmp set on c3gGsmRoamingPreference, you get the error message “Commit failed.”

There is no workaround. Limitation is by design for security reasons.

c3gMsisdn shows an empty string in an SNMP walk.

SNMPget on c3gMsisdn.

There is no workaround. This issue is carrier dependent. When this issue is seen in the field, check with your service provider to see whether MsIsdn is populated by the service provider. For example, AT&T does provide the MsIsdn value and T-Mobile does not.

When a SNMP set is issued to create a row in the PDP profile table, commitFailed was seen.

snmpset -v 3 -u sgbublr -l authPriv -a MD5 -A cisco1234 -x AES128 -X cisco1234 172.27.168.114 c3gGsmPdpProfileRowStatus.22.2 i 4

Error in packet.

Reason: commitFailed

Failed object: CISCO-WAN-3G-MIB::c3gGsmPdpProfileRowStatus.22.2

SNMP set operations are not allowed on c3gGsmPdpProfileTable for security reasons.

Use the CLI to create a new profile for profile 3 as shown in the example below:

cgr1000# cellular 3/1 gsm profile create 3 PRO3

Profile 3 will be created with the following values:

PDP type = IPv4

APN = PRO3

Are you sure? [confirm]

Profile 3 written to modem

ciscoWan3Gmib does not support a write function for the c3gGsmChv1 object.

When a user issues a set c3gGsmChv1 command, the set fails. By design, the write function (disabled by default) does not work on most of the ciscoWan3gMib for security reasons.

change-pin Old-PIN New-PIN to set Card Holder Verification 1 (CHV1). Example below:

CGR1K# cellular 5/1 gsm sim  change-pin  0000 1111

A write on c3gCdmaSecurityTable results in commit failed.

Error: Commit failed

Error index: 1

1: c3gCdmaPinSecurityStatus.23 (INTEGER) unknown(1)

***** SNMP SET-RESPONSE END *****

User uses snmp create a row in the security table as the MIB has access to create a row. This results is failure as write is not supported in IOS for this MIB.

SNMP write on most of ciscoWan3gMib is not supported for security reasons.

Either objects are pre-set or can be set through CLI. SNMP set is not supported.

The OID c3gHdrDdtmPreference is not writable even though it is a read-write object. SNMP write on c3gHdrDdtmPreference is not supported for security reasons.

c3gHdrDdtmPreference always results in Commit Failed errors.

c3gHdrDdtmPreference for a cellular preference as enabled or disabled. For example:

To enable cdma ddtm for cellular 3/1:

CGR1000#config terminal

CGR1000(config)#controller cellular 3/1

CGR1000(config-controller)# cdma ddtm

MIB OID c3gCdmaRoamingPreference does not have corresponding CLI. The write operation of c3gCdmaRoamingPreference results in "Commit failed" errors. The write of c3gCdmaRoamingPreference is not supported due to security reasons.

User wants to identify the Roaming Preference through CLI. its not shown. It is available only via mib get.

The write of c3gCdmaRoamingPreference results in "Commit failed" errors.

Roaming Preference value.

Issue snmpset on any of c3gMdn,c3gCurrentNid, c3gCurrentSid,c3gSipUsername or c3gSipPassword MIB objects. The following occurs:

Error: Commit failed

Error index: 1

1: c3gSipUsername.23 (DisplayString) 0000005308@vzw3g.com [30.30.30.30.30.30.35.33.30.38.40.76.7A.77.33.67.2E.63.6F.6D (hex)]

SNMP write on most of the ciscoWan3gMib is not supported for security reasons.

There is no workaround.

Cannot SSH into the CGR with SSHv2 protocol.

When using Airspan base station with CGR1000 dot16 modules, the latency may increase if the dot16 uplink throughput is very low (around 200 Kbps or less).

If the uplink throughput is very low (around 200 Kbps or less), the latency may increase (especially with the Best Effort service-class). This is because Airspan base stations expect a certain minimum rate of traffic before processing the traffic.

Configure a QoS scheduling method like rTPS on the base station to minimize the increase in the uplink latency at very low traffic rates.

You cannot download the software image bundle for this release when operating with SSHv1.

By default, the GOS image that comes with the software bundle image only supports SSHv2. You must enable SSHv2 in Cisco IOS in order to download any TPMC package or application to the GOS.

Enable SSH2 in Cisco IOS.

The system reset-reason may show “Thermal Trip” after a power outage.

When a CGR is power-cycled due a power loss event, the system reset-reason may show a false “Thermal Trip” reset instead of “Power-on”. This is because the unstable voltage on the mainboard may trigger a false “Thermal Trip” reset-reason.

to check the sensor temperature. If they show normal values, the Thermal Trip reset-reason can be ignored and no further action needs to be taken.

The line protocol on the dot16 interface may not go down after restoring the interface to default configuration.

Configure the necessary settings for the dot16 interface to come online. Restore the interface to default settings. The dot16 interface line protocol may stay up.

Perform a shutdown on the interface.

Caveats

to find further details on those caveats. This section includes the following topics:

■Open Caveats

■Accessing Bug Search Tool

Open Caveats

The message, modem is not present, is seen when the modem is plugged in.

Module is stressed with power UP/DOWN, dual SIM failovers, and modem power cycles and resets along with traffic.

There is no workaround for this issue. Reboot the CGR.

Modem crash memdump from the modem is not retrieved.

Even when the modem crash tool is enabled, the memdump is not retrieved.

There is no workaround for this issue.

The AT Command response from the modem is very slow when bidirectional traffic is sent across the cellular interface.

Bidirectional traffic is sent across the cellular interface.

Stop all traffic and reload the CGR to access the AT commands.

The following tracebacks are seen when GSM/CDMA modem crashes:

%SYS-3-BAD_RESET: Questionable reset of process 314 on tty3/1

-Process= "TTY Daemon", ipl= 0, pid= 333

-Traceback= 1845341z 1733927z 1734FA8z 22D2AA0z

Occurs when CDMA/GSM modem crashes.

a cellular interface might not automatically be placed in an admin non-shut state when its 3G module is administratively powered up from a powered-down state.

When the 3G module is powered down, its cellular interface will also be put in admin shut state. When the 3G module is powered up again, its 3G interface will be automatically put back in admin no-shut state.

However, if the 3G module is powered-down and the CGR is rebooted, the 3G interface may not be put in admin no-shut state when the 3G module is powered up again. Users may see this error "cellular_error_log: DS instance init issue". When such an error occurs, the cellular interface will not be automatically put in admin no-shut state when the 3G module is powered up.

command

Cellular 3G interface is shown in shutdown state even after the module is powered on.

CGR (with a 3G module installed) was powered off and reloaded to ensure that the cellular interface was not in an admin down state. After the CGR boots up and the 3G module is powered on, the module remained in an admin down state.

Shutdown and no shutdown commands need to be performed on the cellular interface after the CGR boots up.

The dot16 interface may be set to admin shut in startup-config under some race conditions.

Under some race condition (e.g. a copy run start operation is happening during a module power-cycle due to recovery or wan-mon), the dot16 interface configuration may be set to administrative shutdown. If the CGR is reloaded, this interface may stay in admin shut state

in the interface configuration mode if the interface stays in the admin shut state after a reload.

c3gModemTemperAbateNotif trap generates only after the c3gModemTemperOnsetNotif trap has already been generated once.

c3gModemTemperAbateNotif is working like recovery trap rather than a discrete trap.

There is no workaround.

Malloclite memory leak occurs every 15-20 minutes.

This issue is reproducible, but not consistently. An example is shown below:

Chunk Elements:

AllocPC Address Size Parent Name

396D354 11EBC210 100 12F462CC (MallocLite)

396D354 13EFD8C4 48 13036424 (MallocLite)

396D354 13EFE484 48 13036424 (MallocLite)

396D354 13EFE504 48 13036424 (MallocLite)

There is no workaround. Router reboot does not help.

Documentation Updates

This section includes the following late updates to documentation for the CGR 1000:

■Virtual WPAN (VWPAN) Interface

■Raw Socket over L2 VPN

■NTP timing based on GPS Clock

Virtual WPAN (VWPAN) Interface

The CGR 1000 provides security services to wireless and power-line communication (PLC) mesh endpoints. This is done by enabling these services on corresponding WPAN and PLC IOS interfaces. For a partner-developed WPAN module that connects to Guest-OS (GOS), the same set of services are not directly available.

A new Virtual WPAN interface is included in this Cisco IOS release to provide 802.1X and Mesh-security services. This interface serves as the anchor to the Port Access Entity (PAE) for the partner module and the end-points. It also provides configuration and monitoring CLI commands.

The VWPAN interface has three main subsystems:

■Partner Module - The module connects to GOS directly using USB. The partner module must have an embedded 802.1X supplicant.

■Extensible Authentication Protocol ( EAP ) relay application - A partner-developed GOS application that functions as an EAP relay between the module and IOS. EAP packets received from the module are forwarded to Cisco IOS and are likewise processed in the reverse direction. The application uses an API library (libvwpan) that Cisco provides to communicate with Cisco IOS.

■Cisco IOS Virtual WPAN interface - Provides the 802.1X and Mesh-security services for partner module and mesh endpoints.

Figure 1 shows the high-level architecture.

Figure 1 VWPAN Architecture

Interface Configuration and Monitoring

VWPAN 1X and Mesh-security interface configuration and monitoring is identical to the physical WPAN interface. All the 802.1X and Mesh-security CLI commands are available and behave the same way.

For example, the following creates and configures a VWPAN interface and sets up the 802.1X authenticator in multi-auth mode:

conf t

interface Virtual-WPAN 0

authentication host-mode multi-auth

authentication port-control auto

dot1x pae authenticator

Raw Socket over L2 VPN

command to configure the MPLS virtual connection.

When data comes in from the asynchronous mode serial port (or UART), the CGR 1000 packetizes the data using the configured criteria for raw socket and passes the packet to a pre-configured MPLS connection to another point. Then the packet is delivered to a local UART. This process is bidirectional.

The following example shows a serial interface on the CGR 1000 configured for Raw Socket MPLS VPN:

cgr1000# show run inter async1/1

Building configuration...

Current configuration : 132 bytes

!

interface Async1/1

physical-layer async

no ip address

encapsulation trans

xconnect 9.9.10.1 112000 encapsulation mpls

end

.

NTP timing based on GPS Clock

A new global configuration command configures the GPS time as the reference clock for NTP:

The GPS time acts as a stratum 0 source, and the Cisco IOS NTP server acts as a stratum 1 device, which in turn provides clock information to its NTP clients (stratum 2 and 3).
