Datasheet

Routing functions

Dynamic routing with RIPv2. Learning and propagating routes; separate settings for LAN and WAN. Extended RIPv2 including HopCount, Poisoned

Reverse, Triggered Update for LAN (acc. to RFC 2453) and WAN (acc. to RFC 2091) as well as filter options for propagation of routes. Definition

of RIP sources with wildcards

Dynamic routing

DHCPv6 client, DHCPv6 server, DHCPv6 relay, stateless- and stateful mode, IPv6 address (IA_NA), prefix delegation (IA_PD), DHCPv6 reconfigure

(server and client)

DHCPv6

Layer 2 functions

VLAN ID definable per interface and routing context (4,094 IDs) IEEE 802.1qVLAN

Packets sent in response to LCOS service requests (e.g. for Telnet, SSH, SNTP, SMTP, HTTP(S), SNMP, etc.) via Ethernet can be routed directly to the

requesting station (default) or to a target determined by ARP lookup

ARP lookup

Automatic discovery of network topology in layer 2 networks (Link Layer Discover Protocol)LLDP

COM port server

COM-port server for DIN and USB interfaces. For multiple serial devices connected to it, the server also manages its own virtual COM ports via

Telnet (RFC 2217) for remote maintenance (works with popular virtual COM-port drivers compliant with RFC 2217). Switchable newline conversion

and alternative binary mode. TCP keepalive according to RFC 1122 with configurable keepalive interval, retransmission timeout and retries

COM port forwarding

USB print server

Host port for connecting USB printers via RAW-IP and LPD; bi-directional data exchange is possiblePrint server (USB 2.0)
