The default buffer sizes allow the router to handle packets with maximum
address overhead and data size for any network variable message and explicit
messages with up to 40 bytes of data; this is large enough for any network
management or network diagnostic message.
For RTR-10 routers with version B firmware, Table 4 shows the transaction
record configurations for receive and transmit transactions, and the buffer
configurations for input buffers, output buffers, priority buffers, and non-priority
buffers.
