SN10K:

IP Interfaces and Internal Subnets

 

This article explains usage of the internal network subnets of SN10100, SN10200 and SN10300 products.  These products need to use private internal subnets for communication between internal modules, and communication units and servers.

 

These subnets must not conflict with other subnets assigned to the other IP interfaces of the units, including management (MGMT0), and VOIP IP interfaces.

 

Procedure to change the internal subnets:

V2.8 or above:

Reset Host Role and change internal IP Addresses 

V2.7 or below:

Contact Support@patton.com for instructions

 

IP Interface table:

* Not all units support changing this subnet


General information:

 

'int0' subnet:

  • Usage
    • This subnet is used for communication between Embedded host and Teleco board within the unit.

  • Products using this subnet
    • This subnet is used by all SN10100 and SN10200 products.
    • This subnet is not used by SN10300 products.

  • Default IP / Netmask
    • The default IP / Netmask for this subnet is: 172.31.1.1 / 255.255.255.252 (range 172.31.1.1 - 172.31.1.3).

  • Support for changing this subnet
    • This subnet cannot be changed on most SN10100 and SN10200 Units.

Inter-Unit private 'eth0' and 'eth1' subnets:

  • Usage
    • These subnets are used for reliable and redundant communication between Units of the system (between two SN10100 or SN10200 in 1+1 mode, or between servers and Units of a SN10300 system)

  • Products using these subnets
    • These subnets are used by SN10100 and SN10200 units configured in 1+1 mode. They are not used in Standalone mode.
    • These subnets are used by all SN10300 systems.

  • Default IP / Netmask
    • The default IP / Netmask for 'eth0' subnet is: 172.16.0.0 / 255.254.0.0 (range 172.16.0.1 - 172.17.255.255)
    • The default IP / Netmask for 'eth1' subnet is: 172.18.0.0 / 255.254.0.0 (range 172.18.0.1 - 172.19.255.255)

Note that these subnets use a large netmask, allowing each shipped Unit to have a unique IP address on these subnets set in production. This is very convenient, because it allows you to add a new 'off-the-shelf' SN10300 Telecom Unit to an existing SN10300 system without manually changing the IP address of eth0 and eth1 interfaces. It also allows inserting a new 'off-the-shelf' unit (or replacement unit) in a SN10100 or SN10200 1+1 system without manually changing the IP addresses.
