The configuration and runtime scripts created are as follows:

•

S70Surviving_partner

Switch initialization script that is run at boot time. This

script will restart the switch with the original configuration given to

zspconfig

.

Optionally,

zspconfig

will run this script from the initial invocation.

•

zsp.conf.<n> -

zspconfig

configuration file that contains the configuration of

the sibling backup switches. The

<n>

is used to distinguish potentially more than one

backup switch. This configuration file is placed in

/tftpboot

, and is retrieved via

DHCP during configuration of the backup switch by

zspconfig

with the “

-u

” option

or, by a replacement switch on boot up.

•

vrrpd.conf -

Configuration script for the VRRP daemon. This configuration is

used when the S70Surviving_partner script launches vrrpd. There is a line in this file for
each virtual router address vrrpd will manage.

•

dhcpd.conf -

Configuration script used by

dhcpd

when the switch becomes

master.

dhcpd

is also used to give replacement switches their configuration scripts.

Namely a zsp_.conf<n> file that can be input to

zspconfig

with the

-u

flag.

•

dhclient.conf -

If

zspconfig

is executed with the

-u

flag, a dhclient.conf file

is created, and then dhclient is used to retrieve a

zspconfig

configuration file from the

/tftpboot area of the Master switch.

•

vrrpd.script -

Runtime script that executes each time the vrrpd changes state.

This script starts and stops

dhcpd

, and toggles down RAINlink ports to force the

RAINlink nodes to a new Master switch.

•

zlmd.script -

Runtime script executed by zlmd when a link goes up or down. This

script modifies the priority of the vrrpd that in turn may cause the VRRP Master to move
from one sibling switch to another.

After the scripts are created,

zspconfig

may run the

S70Surviving_partner

script to start

the Surviving Partner tasks. The tasks started are vrrpd, zlmd, and

dhcpd

.

The

vrrpd

and

zlmd

daemons run scripts to perform their actions. When

vrrpd

changes state

between Master and Backup, it runs a script that starts and stops

dhcpd

. When

zlmd

sees a link

go up or down, it runs a script that communicates with

vrrpd

via

vrrpconfig

.

Example HA Switch Configuration

The following walks through a basic Surviving Partner configuration typical for an HA setup.
Assume an HA chassis with multiple hosts, such as single-board CPUs, and two switches
configured for Surviving Partner. Each of the hosts has two Base Ethernet ports providing a link
to each of the Base switches and up to four fabric Ethernet ports providing links to each of the
Fabric switches.

Each host runs Linux bonding drivers (or ZNYX OA Node software with embedded RAINlink)
with the ports configured for failover. An interlink provides communication between the Base
switches. Another interlink provides communication between the Fabric switches.
