Platform Specific Configurations

ENCS Switch Configuration

Access to the ENCS switch is restricted through Consent Token. Consent Token is a security feature that is used to authenticate the network administrator of an organization to access system shell with mutual consent from the network administrator and Cisco Technical Assistance Centre (Cisco TAC).


Note

  • From the switch console, there is access to debug mode and an advanced debug mode. Credentials of the local user are synchronized to access debug mode. Advanced debug uses unique credentials for each device that allows for additional debugging options for Cisco engineering. To enter either debug mode permission must be granted through Consent Token.

  • To configure any parameter on the ENCS switch portal, ensure that you add or remove parameters using separate transactions on the CLI. For example, adding and removing multiple VLANs from the ENCS switch portal is not supported in the same CLI transaction. Add a VLAN first and then remove the VLAN in a separate transaction.

ENCS Switch Portal Configuration

Switch Settings

The Switch option from the Cisco Enterprise NFVIS portal allows you to configure STP/RSTP, VLAN on specified ranges, RADIUS based authentication, and port channel load balancing for various switch ports. This section describes how to configure settings on the ENCS switch portal.

Configuring VLAN

You can use virtual LANs (VLANs) to divide the network into separate logical areas. VLANs can also be considered as broadcast domains. Any switch port can belong to a VLAN, and unicast, broadcast, and multicast packets are forwarded and flooded only to end stations in that VLAN. Each VLAN is considered a logical network, and packets destined for stations that do not belong to the VLAN must be forwarded through a router.

You can configure VLANs in the range <1-2349>|<2450-4093> for a specified switch port.


Note

  • When you use multiple Virtual Network Inteface Cards (VNICs) in your VLAN, ensure that each of the VNICs are configured within the VLAN network.

  • The Cisco ENCS hardware switch is typically connected to the Open vSwitch (OVS) using physical connections (like Ethernet cables) which are then represented as ports within the Open vSwitch configuration. When a VLAN is set up on the Cisco ENCS switch, perform the corresponding configuration on the OVS as well. Assign a VLAN tag to the OVS port that corresponds to the hardware switch port.

  • Use native VLANs for untagged traffic. If a hardware switch port is configured to use a certain VLAN as native, corresponding OVS port should also be configured to tag the untagged incoming traffic with the same VLAN. Allowed VLAN lists define which VLANs are allowed on a port.

  • While a hardware switch and OVS are logically connected, configurations do not automatically propagate between the two. Manually configure the both to ensure consistency and correct networking behavior.

Configuring General Settings

You can configure general settings using the following parameters for each switch interface:

  • Interface—Name of the interface

  • Description—Set the description per interface

  • Speed—10/100/1000 MBPS

  • Dot1x Auth—802.1x, mac or both

  • PoE Method—auto, never or four-pair

  • PoE Limit—0-60000mW

  • Admin Status—enable or disable

Configuring Advanced Settings

You can make the advanced settings using the following parameters for each switch interface:

  • Mode—access, dot1q-tunnel, private-vlan, or trunk

  • Access Vlan—Specifies the number of VLANs.

  • Allowed Vlan—All or VLAN IDs

  • Native Vlan—Specifies the VLAN ID. You can enter a value from one of the following ranges:

    • 1 to 2349

    • 2450 to 4093

  • Dot1q Tunnel Vlan—Specifies the Layer 2 tunnel port.

  • Community—Specifies the community number. Range: 1 to 29

  • Protected Port—Yes or No


Note

The VLAN configuration takes effect only if the global VLANs are also configured with the same values in Configuring VLAN.

Configuring Spanning Tree per Interface

You can configure spanning tree for each switch interface using the following parameters:

  • Spanning Tree—Enable or Disable

  • Cost—Specifies the cost. Range: 1 to 200000000

  • Priority—Specifies the port priority. Range: 0 to 240, default value is 128

  • Link Type—point-to-point or shared

  • BPDU Guard—Enable or Disable

  • Root Guard—Enable or Disable

  • Port Fast—auto or enable

  • BPDU Filtering—Specifies that BPDU packets are filtered when the spanning tree is disabled

  • BPDU Flooding—Specifies that BPDU packets are flooded when the spanning tree is disabled

Configure Storm Control

Storm control is used to monitor incoming traffic levels and limit excessive flow of packets on any user facing switch port that could cause a traffic storm. Traffic storms can lead to device instability and unintended behavior.

You can configure storm control from Cisco NFVIS Portal, from Storm Control tab.

Storm control can be configured for specific type of traffic - unicast or multicast or broadcast. The suppression range can be in terms of a percentage level (1-100) or Kbps value (1-1000000).

Description

Configure Additional WAN Transport Connectivity On ENCS Switch Ports

NFVIS Release 4.10

This feature enables configuring additional Transport Locator (TLOC) an attachment point. The attachment point is where a Cisco WAN Edge device connects to a WAN transport using ENCS LAN ports as WAN ports. This is in addition to the currently available WAN connectivity options that is restricted to just two WAN ports.

Starting from NFVIS Release 4.10, map LAN SR-IOV (Single Root Input or Output Virtualization) with Cisco ISRv or Cisco Catalyst 8000V to configure additonal WAN transport connectivity on ENCS switch ports. The following are the changes to ENCS LAN and WAN ports connectivity:

  • The WAN circuit TLOC terminates on layer 3 ports (GE0-0 or GE0-1).

  • The WAN circuit TLOC physically connects to any switch port (GE1/0 - GE1/7).

  • The LAN traffic flows through the switchports (GE1/0 - GE1/7).


Note

Cisco Security Group Tag (SGT) is added to the LAN interfaces which are propagated to all the TLOCs that are handled by VNFs such as Cisco ISRv or Cisco Catalyst 8000V. For more information see, Cisco TrustSec Integration.

Configuring vBranch High Availability

High availability design provides redundancy for WAN, LAN, ENCS device, vRouter, vFirewall VNF level redundancy.

A branch site can have two routers for redundancy. If vEdge-cloud router is chosen, Each of the vedge-cloud router maintains:

  • A secure control plane connection, via a DTLS connection, with each vSmart controller in its domain

  • A secure data plane connection with the other vEdge routers at the site

Because both vEdge routers receive the same routing information from the vSmart controllers, each one is able to continue to route traffic if one should fail, even if they are connected to different transport providers.

Two firewalls are placed in a group and their configuration is synchronized to prevent a single point of failure on your network. A heartbeat connection between the firewall peers ensures seamless failover in the event that a peer goes down. Setting up two firewalls in an HA pair provides redundancy and allows you to ensure business continuity.

Prerequisites for vBranch HA

The WAN links are active on both Cisco ENCS1 and Cisco ENCS2. Each of the ENCS WAN link is connected to the WAN network (most cases with two SPs), with two ENCSs in an active-active mode.

The LAN facing links of both Cisco ENCS devices are connected to an external switch (as an uplink), and all the devices on the LAN segment are also connected to the external switch. There should be no LAN device connecting directly to the Cisco ENCS internal switch.

Two vRouters and the Two vFirewalls have full mesh L3 connectivity.

VMs and VNFs on both ENCS devices must be configured identical.

SD-Branch HA Design and Topology

In HA design, there are two sets of VLANs. Traffic path is between the VNFs and traffic from or towards LAN.

To protect against cable connection issue and box failure, there is back-to-back cable between ENCS and connection from each ENCS to the external switch.

When using Cisco ENCS and Cisco switches, common expectation is to use PVST+, detect loops and switch specific ports to BLOCKING mode. ENCS switch does not support PVST (Per VLAN spanning tree). By Default, RSTP could end up blocking ENCS port back-to-back connection, this will result in blocking traffic path between the VNFs.

The recommended solution is to use MSTP in ENCS and the external switches. The following topology and configuration provides a step-by-step procedure with reasoning for specific configuration use. There are two instances of MSTP created. One for handling traffic path between VNFs and the second for handling traffic from or towards LAN.


Note

In cases where external switch cannot be configured for MSTP, RSTP is used and the two links back-2-back between ENCS is not in port-channel.

  • One of the links carries traffic between VNFs by configuring disable spanning tree. The second back-to-back link between ENCS processes RSTP and forward or block for the traffic from or towards LAN.

  • From each of the ENCS, a third physical link connects to the external switch. This also forwards or blocks the traffic from or towards LAN depending on the RSTP decisions.

Physical Device Connections

VM and Service Chain Network Connection

Figure 1. ENCS-Left
Figure 2. ENCS-Right

Note

In the absence of firewall in the design, the router is directly connected to the LAN side. Pt-to-Pt network extends the TLOC connection across the ENCS devices and VRRP is enabled in the router LAN facing connection.

Isolating LAN and Transit Link Traffic for vBranch HA

Traffic from or towards LAN and traffic between the VNFs are isolated by configuring different VLANs for each traffic since both links are connected to the same ENCS internal switch. If you do not isolate the traffic, both LAN traffic and transit link will flow through the same internal switch on the Cisco ENCS.

Enable Port Tracking and Virtual NIC Update

The configured VNICs tracks the state of the ports based on the PNICs notifications. To verify the state of the port, use show interface or ethtool commands. You can also use commands specific to the VM, that displays the interface link state.

To configure track state on GE0-0 & GE0-1:


configure terminal
pnic GE0-0 track-state ROUTER 1
end

Packet Flow for SD-Branch HA

This section explains high-level packet flow in non-failure and failure cases.

Non-Failure Case

In the non-failure case, both ENCS devices are Active, up and running

  • LAN to WAN through the ENCS1 Firewall and ENCS1 Router

  • LAN to WAN through the ENCS1 Firewall and ENCS2 Router

  • WAN to LAN through ENCS1 Router and ENCS1 Firewall

  • WAN to LAN through ENCS2 Router and ENCS1 Firewall

Failure Case

Following are failures that a router must be designed and configured to adapt

The conditions that trigger a firewall failover are:

  • One or more of the monitored interfaces fail. (Link Monitoring)

  • One or more of the destinations specified on the firewall cannot be reached. (Path Monitoring)

  • The firewall does not respond to heartbeat polls. (Heartbeat Polling and Hello messages)

In a HA design involving a router or Firewall, there are 3 to 6 paths required. ENCS platform has 2 WAN facing ports and 8 LAN facing ports.

  • WAN facing ports are reserved for connection to WAN circuits.

  • LAN facing ports are the only set of available ports for creating the 3 to 6 path required.

Between VNFs and LAN, OVS or SR-IOV VFs and physical switch ports are the two Layer2 entities to traverse.

VLAN must be explicitly created before they are used in the interfaces.

Enable MSTP. For MST group 2 carrying “Traffic towards/from LAN”, force the External Switch to become the ROOT using the “mst <group> priority <value>” CLI. The Higher the value, lower the chance of becoming spanning-tree ROOT.

“priority” configuration is NOT required for the MST group 1 carrying “Traffic between VNFs”. There is NO loop possibility for MST group 1 VLANs.

For the back-to-back ENCS connection, link redundancy is achieved using port-channel configuration. Interfaces that are belong to a port-channel group use configuration from “interface port-channel x”

Goal is to prefer the direct links from ENCS to the External Switch for “Traffic towards/from LAN”. In ENCS back-to-back connection, Spanning tree cost is HIGH for MST group carrying “Traffic towards/from LAN”. This config will block one of the ENCS back-to-back interfaces for breaking the loop for MST group carrying “Traffic towards/from LAN”.

Status of MST instances.

For MST instance 1, “Traffic between the VNFs”, back-to-back portchannel link is root and forwading state.

For MST instance 2, “Traffic from/towards the LAN”, links connected to External Switch are in forwarding state, path via back-to-back portchannel link is “Blocking state”. If one of the Links fail between ENCS and External switch, portchannel path for MST instance 2 will be unblocked.

From the above summary output, MST instances indicates ID and associated VLAN, and then displays all interfaces as part of VLAN instances. This behaviour differs from the way MST instances are displayed on other Cisco switching platforms.

External Switch MST Configuration


Note

It is recommended that VLAN 996-998 is not allowed through the interfaces connecting to ENCS-Left and ENCS-Right. As a result, the external switch MSTP does not participate for VLAN 996-998.

VLANs carrying “Traffic between the VNFs” are NOT sent to the External Switch.

MST instance priority and MST link COST are kept default in the External Switch.

MST Priority and COST Configuration in ENCS ensure the External switch is the root and the Interfaces in the External switch connecting to ENCS are in Forwarding state.


Note

VLANs carrying traffic between VNFs are not used in external switch and not configured in any interface.

CIMC Secure Overlay Support

Table 7. Feature History

Feature Name

Release Information

Description

CIMC Secure Overlay Support

NFVIS 4.4.1

This feature enables you to recover NFVIS when it becomes unresponsive. CIMC periodically monitors NFVIS health and when NFVIS health check fails, CIMC establishes a secure tunnel to the remote location. You can then log in to CIMC from the remote site to troubleshoot and recover NFVIS.

The CIMC secure overlay feature is a disaster recovery feature to recover an unresponsive NFVIS. NFVIS is managed from a remote location using a secure (IPsec) tunnel. If NFVIS hangs and does not recover by itself, you must reboot or reinstall NFVIS. With this feature, CIMC periodically monitors NFVIS health. CIMC gets NFVIS secure tunnel details when a secure tunnel is set up from NFVIS to the remote location. When NFVIS health check fails, CIMC waits for an hour by default for NFVIS to recover by itself. If NFVIS does not recover, CIMC establishes a secure tunnel to the remote site.

CIMC can access the remote site at the same NFVIS external IP address. At the remote site, you can log in to CIMC and do the necessary troubleshooting to recover NFVIS. After NFVIS is back up, the CIMC secure tunnel is broken and secure tunnel is established between NFVIS and the remote site again.


Note

For this feature to work:

  • Secure IPSec tunnel should be configured on NFVIS.

  • The feature should be enabled in CIMC during deployment.

The following example shows how to enable secure overlay feature on CIMC:


ENCS# scope ipsec-tunnel 
ENCS/ipsec-tunnel# show detail 
    Enable Failover: no
    NFVIS Down Timeout: 3600
    Tunnel Status: NO_TUNNEL
    Seconds to Failover: 0
ENCS/ipsec-tunnel# set ?
  cli                     CLI options
  nfvis-down-timeout      Number of seconds CIMC waits before starting ipsec tunnel to remote
  tunnel-failover-enable  Enables failover of ipsec tunnel when NFVIS is down

ENCS/ipsec-tunnel# set tunnel-failover-enable yes
ENCS/ipsec-tunnel# set nfvis-down-timeout 3600
ENCS/ipsec-tunnel# commit
ENCS/# show detail 
    Enable Failover: yes
    NFVIS Down Timeout: 3600
    Tunnel Status: NO_TUNNEL
    Seconds to Failover: 0 
ENCS/ipsec-tunnel# show
Enable Failover NFVIS Down Timeout Tunnel Status    Seconds to Failover
--------------- ------------------ ---------------------- -------------------
 yes             3600               TUNNEL_ESTABLISHED     0      

The CIMC tunnel status can be one of the following:

  • TUNNEL_ESTABLISHED = all ok and remote can login to CIMC

  • TUNNEL_CONFIG_MISSING = IPsec config was not transferred to CIMC

  • TUNNEL_ERROR = Runtime error

  • UNKNOWN_ERROR

CIMC TACACS Support

Table 8. Feature History

Feature Name

Release Information

Description

CIMC TACACS Support

NFVIS 4.2.1

CIMC TACACS configuration support enabled on NFVIS.

TACACS+ is a security protocol that provides centralized validation of users attempting to gain access to a router or network access server. TACACS+ services are maintained in a database on a TACACS+ server running, typically, on a UNIX or Windows NT workstation. You must configure a TACACS+ server before you configure the TACACS+ features on your network access server and make them available.

On the TACACS+ server, ensure you configure Cisco attribute-value (AV) pair privilege level (priv-lvl) for Cisco Integrated Management Controller (CIMC) service for the minimum privilege level of administrators and operators.

In CIMC TACACS configuration, privilege level 14 is assigned to the administrator role, and privilege level 9 is assigned to the operator role. This means a user with privilge level 14 or higher has admin privileges when the user logs into the system, and a user with privilege level 9 or higher has all privileges of an operator at the time of login.

Privilege level below 9 has the read-only privileges.

These two are optional arguments. By default admin-priv is 15 and oper-priv is 11.

To configure a TACACS server on CIMC:


Server /# scope tacacs
Server /tacacs# set tacacs-server ip-address
Server /tacacs*# set tacacs-key <keystring>
Server /tacacs*# set tacacs-enable yes
Server /tacacs*# set admin-priv 12
Server /tacacs*# set oper-priv 5
Server /tacacs*# commit
Server /tacacs# show detail

To verify the TACACS+ server configuration:


Server/tacacs# show detail

tacacs Settings:
    Server domain name or IP address:
    Enable tacacs: yes
    shared-secret key: ******
    admin-priv: 14
    oper-priv: 10

For more information about this feature, see TACACS+ Server.

Verifying LTE PIM Module Network Connectivity

After Cisco Catalyst 8200 UCPE boots up with a supported LTE PIM and a carrier SIM card, you can verify if the LTE PIM module is connected to the carrier network using the show cellular 1/0 details command.

The following example shows how to verify if the LTE PIM module is connected:


C8200-NFVIS# show cellular 1/0 details
details IPv4 address =     101.144.109.57  <-- IP address obtained
details Default Gateway Address =  101.144.109.58
details Interface subnet mask =  255.255.255.252
details Interface name =   int-CELL-1-0
details Interface Status =  up
details DNS IP Address =   101.224.173.135
details Modem Status =     Call_Connected  <-- Cellular call connected
C8200-NFVIS#

For a successful network connection:

  1. The LTE PIM module should be able to obtain an IP address.

    • Example here is 101.144.109.57.

    • If the SIM card has a dynamic IP address, this IP address would change over time. This works the same way as dynamic IP address assignment with wired network.

  2. Modem status should show as Call_Connected.

  3. Ping to any public IP network should be successful (8.8.8.8).

If any of the above are incorrect, see the troubleshooting section below.

LTE PIM Module LED

For information on LTE PIM module's LED colors and behaviors, see LTE LED Details.

Online Insertion and Removal (OIR) of LTE PIM Module

You can replace the LTE PIM module without affecting the Cisco Catalyst 8200 UCPE platform system operations with the online insertion and removal (OIR) operation. OIR commands are issued before removing and after installing an LTE PIM. When you perform OIR, use an identical or another variation of LTE PIM module to replace the original one.

Command

chassis compute inventory pim-modules units 0/1/0 [reload | start | stop]


Note

Removing the LTE PIM module without executing the chassis compute inventory pim-modules units 0/1/0 stop command is not supported.

DM Log Collection on LTE PIM Module

Diagnostic Monitor (DM) is a Qualcomm proprietary protocol. Diagnostic software tools, such as Sierra Wireless SwiLog and Qualcomm QXDM, are based on DM protocol. These tools can be used to capture data transactions between the modem and the network over the RF interface, which makes them useful tools for troubleshooting 3G and 4G data connectivity or performance issues.

To start DM log collection

The following example shows how to start DM log collection using the dm-log enable command: 

C8200-NFVIS# config terminal
Entering configuration mode terminal
C8200-NFVIS(config)# controller cellular 1/0
C8200-NFVIS(config-cellular-1/0)# dm-log enable
C8200-NFVIS(config-cellular-1/0)# commit
Commit complete.
C8200-NFVIS(config-cellular-1/0)# end
C8200-NFVIS#

Note
DM log rotation is enabled by default.

To stop DM log collection

The following example shows how to stop DM log collection using the no dm-log enable command: 

C8200-NFVIS# config terminal
Entering configuration mode terminal
C8200-NFVIS(config)# controller cellular 1/0
C8200-NFVIS(config-cellular-1/0)# no dm-log enable
C8200-NFVIS(config-cellular-1/0)# commit
Commit complete.
C8200-NFVIS(config-cellular-1/0)# end
C8200-NFVIS#

To view DM log collection status

The following example shows how to view the status of DM log collection using the show cellular 1/0 status command: 

C8200-NFVIS# show cellular 1/0 status

To retrieve the collected DM log file

Download the system's tech-support file.

To configure DM log non-default filter

  • SCP the DM log filter onto C8200-UCPE-1N8.

    scp <username>@<server_ip>:<dm_log_filter_file> intdatastore:<dm_log_filter_file>

    Example:

     scp admin@192.19.145.241:/home/gpsmask.sqf intdatastore:gpsmask.sqf

  • Configure specific DM log filter.

    dm-log filter-path /data/intdatastore/uploads/<dm_log_filter_file>


    Note

    To enable DM log collection with DM log filter, need to issue “commit” twice:

    1st time: after configure DM log filter

    2nd time: after enable DM log collection

    Example:

      
C8200-NFVIS# config terminal
  Entering configuration mode terminal
  C8200-NFVIS(config)# controller cellular 1/0
  C8200-NFVIS(config-cellular-1/0)# dm-log filter-path /data/intdatastore/uploads/gpsmask.sqf
  C8200-NFVIS(config-cellular-1/0)# commit <-- need to execute before enable DM log 
  Commit complete.
  C8200-NFVIS(config-cellular-1/0)#
  C8200-NFVIS(config-cellular-1/0)# dm-log enable
  C8200-NFVIS(config-cellular-1/0)# commit <-- need to execute again
  Commit complete.
  C8200-NFVIS(config-cellular-1/0)# end
  C8200-NFVIS#

Note
When you use an invalid filter or mistype the filter's name, a DM log file of 0 byte size will be created.

To remove DM log filter

The following example shows how to remove DM log filter using the no dm-log filter-path command: 


C8200-NFVIS# config term
Entering configuration mode terminal
C8200-NFVIS(config)# controller cellular 1/0
C8200-NFVIS(config-cellular-1/0)# no dm-log filter-path
C8200-NFVIS(config-cellular-1/0)# commit
Commit complete.
C8200-NFVIS(config-cellular-1/0)# end

Firmware Upgrade LTE PIM Module’s Modem

From time to time, the LTE PIM's modem requires firmware upgrade to obtain fixes for cellular modem's issues. Firmware upgrade on the LTE PIM module can be done with the following procedure.

  1. Obtain firmware and/or OEM PRI files and put them into a server the C8200-UCPE-1N8 can SCP from.


    Note

    You can find the latest firmware files at https://www.cisco.com/c/en/us/support/interfaces-modules/lte-wireless-wan-interfaces/series.html

    Caution

    Use only Cisco certified firmware. Using a firmware version not certified by Cisco may impact the wireless service provider network adversely.

  2. SCP the firmware or OEM PRI files from the external source to /data/indatastore/uploads folder of the C8200-UCPE-1N8.

    scp <username>@<server_ip>:<fw_file> intdatastore:<fw_file>

    Example:

    scp admin@192.19.145.241:/fw_folder/WP76xx_02.28.03.01_ATT_002.071_000.spk intdatastore:wp7603_02.28.03.01_ATT.spk

  3. Firmware upgrade the LTE PIM's modem.

    cellular 1/0 upgrade-firmware path /data/intdatastore/uploads/


    Note

    • Firmware upgrade process will take up to 15 minutes. During this time the modem will be unusable. Please do not remove power or reload the C8200-UCPE-1N8 during the firmware upgrade process.

    • Firmware upgrade status can be seen with show cellular 1/0 status command.

  4. Delete the firmware or OEM PRI files from the /data/indatastore/uploads folder of the C8200-UCPE-1N8.

    system file-delete file name /data/intdatastore/uploads/<fw_file>


    Note

    • There can only be 1 firmware/OEM PRI file in the /data/indatastore/uploads folder for each firmware upgrade process.

    • For EM74xx modems' firmware upgrade, only have 1 .CWE and 1 .NVU files in the folder.

    • For WP76xx modems' firmware upgrade, only have 1 .SPK file in the folder.

    • For EM74xx modems' and WP76xx modems' OEM PRI upgrade, only have 1 .NVU file in the folder.

Enabling Debug to Troubleshooting LTE PIM Module

    Before you configure, check with your cellular network carrier for the correct values.

  • Verify cellular back-off feature is running or not. When this feature is running, it means that the LTE PIM module is performing necessary back-off operations in order to work smoothly with the provider network. The network provider side initiates this back-off request and the reason for such action depends on the code.

    The following example shows how to verify if the LTE PIM module's cellular back-off feature is running or not, use the show cellular 1/0 connection command: 

    
C8200-NFVIS# show cellular 1/0 connection
Profile 3, Packet Session Status = ACTIVE
Call end mode = None
Session disconnect reason type = None(0)
Session disconnect reason = None(0)
PDN 0
Back off timer is NOT running  <-- cellular back-off feature is not running
Back off error count = 0
Back off timer index = 0
Back off timer array (in minutes) = 0 1 1 1 5 10 15 30 60
Cellular interface back-off is not enforced
Period of back-off = 0 minute(s)
C8200-NFVIS#

    If the LTE PIM module has cellular back-off feature running, verify that the cellular profile is configured correctly. If it is configured correctly and you continue to see cellular back-off feature running, check with your cellular network carrier for the reason of back-off.

    For more information on cellular back-off feature, see Cellular Back-Off.

  • Verify that there is a routing table for LTE PIM module's cellular interface or cellular-br. The following example shows how to verify the same using the support show router command: 

    
C8200-NFVIS# support show route
default via 101.144.109.58 dev cellular-br metric 10  <--- default route is through the cellular-br
10.20.0.0/24 dev int-mgmt-net-br proto kernel scope link src 10.20.0.1
166.144.109.56/30 dev cellular-br proto kernel scope link src 166.144.109.57
192.168.1.0/24 dev lan-br proto kernel scope link src 192.168.1.1
192.168.10.0/24 dev csxbr proto kernel scope link src 192.168.10.11
C8200-NFVIS#

    If there are multiple default routes, ensure that the cellular-br metric is lower than the other default route.

  • Troubleshooting your LTE PIM for cellular network connectivity can also be done through the LEDs located at the front of the LTE PIM module. For more information on the LED behaviors, see 4G LTE-Advanced LEDs.

Support for 40G Dual Port and Quad-Split NICs on Cisco Cloud Services Platforms

Table 11. Feature History
Feature Name Release Information Description

Support for 40G Dual Port and Quad-Split NICs in Cisco Cloud Services Platforms

NFVIS 4.7.1

Starting from this release, the 40G network interface card (NIC) supports dual port modes on Cisco Cloud Services Platform (CSP).

Prerequisites for 40G Dual Port and Quad-Split NICs on Cisco CSP

  • Remove the physical network interface card (PNIC) from all networking configurations such as DPDK and SRIOV networks.

  • Remove the PNIC from all bridges.

  • Remove the PNIC from the port channel.

  • Remove the PNIC or virtual functions (VF) of the PNIC from any deployed VM.

Restrictions for 40G Dual Port and Quad-Split NICs on Cisco CSP

  • Plug-n-play of the 40G NIC card is not supported.

  • The breakout and unbreakout commands should not be executed when a Backup and Restore function is in progress.

  • The breakout and unbreakout commands should not be executed when a Factory Default function is in progress.


Note

In a NFVIS Backup and Restore, the NIC card configuration mode must be the same on both the source system and the destination system. If the NIC card configuration is different, the restore command is rejected. For more information, see Appendix.

Information About 40G Dual Port and Quad-Split NICs on Cisco CSP

This feature enables the 40G NIC to support two modes on Cisco CSP:
  • 2x40 mode – two ports of 40G speed each.
  • 4x10 mode – four ports of 10G speed each.

You can convert the 40G NIC from 2x40G mode to 4x10G mode and vice-versa using the breakout commands.

Configure 40G Dual Port and Quad-Split NICs on Cisco CSP Using the CLI

To display the current PNIC modes and adapter information, use the following breakout commands:

nfvis# show pnic-breakout

nfvis# show nic
To change the PNIC mode from 2x40 to 4x10, use the following breakout command:
nfvis# hostaction pnic-breakout device 1 mode 4x10
To change the PNIC mode from 4x10 to 2x40, use the following un-breakout command:
nfvis# hostaction pnic-breakout device 1 mode 2x40

In case of a Return Material Authorization (RMA) of the NIC, you can forcefully breakout or un-breakout between the 2x40G mode and 4x10G mode. For more information on the RMA solution for a 40G NIC, see Appendix.

To forcefully breakout from 2x40 mode to 4x10 mode, use the following command:
nfvis# hostaction pnic-breakout force device 1 mode 4x10
To forcefully un-breakout from 4x10 mode to 2x40 mode, use the following command:
nfvis# hostaction pnic-breakout force device 1 mode 2x40

Configuration Examples for 40G Dual Port and Quad-Split NICs on Cisco CSP

  1. The following example shows how to change the PNIC mode from 2x40 to 4x10:
    
nfvis# hostaction pnic-breakout device 1 mode 4x10 
Warning: Will reboot the system after the mode is changed on the 40G PNIC. All PNIC configuration like adminstatus, duplex, lldp, promiscuous, speed, sriov, track-state will be lost and set to default.
Are you sure you want to perform the PNIC breakout?  [no,yes] yes
