. Example NodeBuilder Device Template for the Router 5000
You can also use this template to export a specific domain configuration (limited
to domain 0) along with a receive transaction timer (typically, 768 ms) and a
location string.
Buffer Configurations
The NodeBuilder FX Development Tool issues an error if you try to build a target
with too large a buffer configuration. For Series 3100 routers, buffering is
constrained by available RAM, but the Router 5000 has sufficient RAM for
buffering (see
Router 5000 Message Buffers
on page 15). However, large buffer
counts (for example, greater than 15) can create conditions where messages
become backed up in the router.
When defining the NET buffer sizes, you must consider the other router-half:
the input buffer size for Side A should be as large as Side B’s output buffer size.
Likewise, the input buffer sizes for Side B should as large as Side A’s output
buffer size. When a router-half forwards a packet to a router half that cannot
accommodate the size of the packet, that packet is dropped.
Creating a Pre-Configured NME File
To create a pre-configured router image:
1.
Use a programming tool to program the NME file produced by the
NodeBuilder FX Development Tool into the router-half
2.
Bring the router-half up and configure it to the desired state
3.
Use a programming tool to extract the configured router image (read the 2
KB EEPROM image), and save it for subsequent device programming
Note
: The Router 5000 firmware ignores all versioning information and
application code components in the NME file.
