After the OAM dashboard service activates, network operators must manually populate the Network Segment Table with IP address details. The Network Segment (NS) then retrieves the information from the Network Segment table (NST) through the config-agent.

The NS maintains the IP association details in a table termed Network Service Association table (NSAT), which is used during the switchover, or when the pod re-requests for an IP address using the same name.

Command Syntax

The available command syntax is based on the chosen networkSegmentType.

Command Parameters


General Parameters (All Network Segment Types)

ParameterLength/RangeDescription

networkSegmentTable

1-23<Name> – The Network Segment Table name for the system.

ipNameV4

1-23

<IPv4 list name> – The list of IPv4 names containing the IP addresses and 'Start' and 'End' IP addresses. 

  • ipList <IP Address> – Enter the list of IP addresses in space-separated format.
  • ipRangeEnd <Ending IP address>
  • ipRangeStart <Beginning IP address>

ipNameV6

N/A

The list of IPv6 names.

networkInterfaceName

N/A

The name of the network interface.

  • mgt0
  • pkt0
  • pkt1

networkSegmentType

N/A

The network segment type for this configuration.

  • OAM  – distributes configuration information to relevant pod instances
  • PFE – When configured, enables Packet Front-End functionality.
  • SC – All types of Media (RTP and X3) land on SC directly
  • SG – When configured, enables the interfacing for non SIP signaling communication. 
  • SLB – Acts as the single entry/exit point for all SIP Signaling to the SBC CNe.

Modified: for 12.1.2

prefixV4

0 - 32<V4 prefix> – The IPv4 prefix for this Network Segment Table.

prefixV6

0 -128<V6 prefix> – The IPv6 prefix for this Network Segment Table.

vlanId

2 - 4094<TAG> – The VLAN TAG assigned to this Network Segment Table.

OAM-specific Parameter

ParameterLength/RangeDescription

networkName

0-255

Specify the primary and secondary (as applicable) network name.

  • primary – Enter the name of primary network. 
  • secondary – Enter the name of secondary (port-redundancy case) network. 

PFE-specific Parameters

ParameterLength/RangeDescription

pfeID 

N/ASpecify a PFE ID.

portRanges

1-23

<Name> – Enter a unique Port Range name, and then specify its parameters.

  • applicationType – Specify the application type for this Network Segment Table.
    • media

  • transport – The protocol type for this Port Range:
    • tcp
    • udp

state

N/A

The Administrative state of the Network Segment Table. You can only change the Network Segment Table when it is disabled, and your changes only take effect once the state changes back to "enabled."

  • disabled (default)
  • enabled

Packet Front-End for Cloud Native SBC (CNe)

Users can configure the networkSegment type "PFE" to set up the Packet Front-End for SBC CNe. Only the PFE and OAM network segment types are allowed in the PFE-based SBC CNe solution.

The following parameters are added to the network segment table to support SBC CNe:

  • PFE ID
  • applicationType
  • rangeStart
  • rangeEnd
  • transport
  • state

For more information on PFE for CNe, refer to: Packet Front-End for Cloud Native SBC.

Command Syntax

Example
% set system networkSegmentTable pfe-pkt0 networkSegmentType PFE pfeID <1-15> networkInterfaceName <pkt0 | pkt1> prefixV4 <0-32> vlanId <0-4095> ipNameV4 <name> ipList <IP Address> portRanges <range name> rangeStart <1-65535> rangeEnd <1-65535> applicationType <signaling | media | signalingGateway> transport <udp | tcp> state <enabled | disabled>
