IP Protocols

The hub supports the following IP protocols:

UDP (User Datagram Protocol)

Provides non-guaranteed delivery service over IP. The hub
implements a full UDP stack. Supports IP fragmentation maximum
packet size of 1520 bytes.

ARP (Address Resolution Protocol)

Allows discovery of the hardware address associated with a given
IP address

ICMP (Internet Control Messages Protocol)

Provides error and control messages. A Ping packet is a type of
ICMP packet.

SNMP (Simple Network Management
Protocol)

Allows management of a network node by another node. The hub
provides full support of SNMP and implements several standard
MIBs as well as product-specific MIBs.

BOOTP (Boot Protocol)

Allows a network node to automatically obtain its IP configuration
from a central BOOTP server; an alternative to individually
configuring each node. Also used to trigger a  TFTP firmware
download.

TFTP (Trivial File Transfer Protocol)

support.

Telnet
