How to Obtain IP Parameters for the STB NIP 2311
EIO0000000051 6/2010 77
Assigning a Fallback IP Address
If the STB NIP 2311 module can not (or is not configured to) obtain an IP address
from a BootP server, DHCP server, or stored IP address, it assigns itself a fallback
(or default) IP address. If a BootP or DHCP server later assigns an IP address, the
BootP or DHCP assigned IP address replaces the fallback IP address:
Frame Format Priorities
The STB NIP 2311 module supports communications in the Ethernet II and 802.3
frame formats. (Ethernet II is the default.)
This table describes the BootP and DHCP behavior of the STB NIP 2311 module
when the Auto-select frame format is used:
Server Type Method
BootP When communicating with a BootP server, theSTB NIP 2311 module makes four Ethernet II frame
format requests, followed by four 802.3 frame format requests. If the NIM completes this cycle of
requests before it receives IP parameters from the BootP server, it simultaneously:
z assigns fallback IP parameters
z continues to make BootP requests until the BootP server assigns IP parameters
DHCP When communicating with a DHCP server, the STB NIP 2311 module makes four requests using the
Ethernet II frame format, then makes four requests using the 802.3 frame format. If the STB NIP 2311
completes making this cycle of requests before it receives an IP address from the DHCP server, it
simultaneously:
z assigns a fallback IP address, and
z continues to make DHCP requests until the DHCP server assigns IP parameters.
