Boot Sequence and SCSN Communication
On initial boot, the SCRN performs the following boot sequence and communicates with the
SCSN. This sequence takes about 1 minute to complete. When completed, all devices are
reachable:
Figure 10 SCRN Boot Sequence
Sequence description:
1. When the SCRN is powered on, the device sends a DHCP Request to the network
DHCP server to get IP information.
2. The DHCP server is configured to use vendor option 43. The server responds with the
IP addresses of the SCRN and the SCSN (the master of the SCRN).
The following example shows a sample configuration from a DHCP server:
option space SPIDERCLOUD;
option SPIDERCLOUD.access-controller code 102 = string;
option SPIDERCLOUD.access-controller "10.1.30.99;";
