Lancom Systems 1681V 62001 Benutzerhandbuch

LANCOM 1681V

Scope of features: as of LCOS version 8.2x

TACACS+

Support of TACACS+ protocol for authentication, authorization and accounting (AAA) with reliable connections and encrypted 

payload. Authentication and authorization are separated completely. LANCOM access rights are converted to TACACS+ levels. 

With TACACS+ access can be granted per parameter, path, command or functionality for LANconfig, WEBconfig or Telnet/SSH. 

Each access and all changes of configuration are logged. Access verification and logging of SNMP Get and Set requests. 

WEBconfig supports the access rights of TACACS+ and choice of TACACS+ server at login. LANconfig provides a device login 

with the TACACS+ request conveyed by the addressed device. Authorization to execute scripts and each command within them 

by checking the TACACS+ server’s database. CRON, action-table and script processing can be diverted to avoid TACACS+ to 

relieve TACACS+ servers. Redundancy by setting several alternative TACACS+ servers. Configurable option to fall back to local 

user accounts in case of connection drops to the TACACS+ servers. Compatibility mode to support several free TACACS+ 

implementations

Remote maintenance of 3rd party 

devices

A remote configuration for devices behind der LANCOM can be accomplished (after authentication) via tunneling of arbitrary 

TCP-based protocols, e.g. for HTTP(S) remote maintenance of VoIP phones or printers of the LAN. Additionally, SSH and Telnet 

client allow to access other devices from a LANCOM device with an interface to the target subnet if the LANCOM device can be 

reached at its command line interface

ISDN remote maintenance

Remote maintenance over ISDN dial-in with calling-number check

TFTP & HTTP(S) client

For downloading firmware and configuration files from a TFTP, HTTP or HTTPS server with variable file names (wildcards for 

name, MAC/IP address, serial number), e.g. for roll-out management. Commands for live Telnet session, scripts or CRON jobs

SSH & Telnet client

SSH-client function compatible to Open SSH under Linux and Unix operating systems for accessing third-party components from 

a LANCOM router. Also usable when working with SSH to login to the LANCOM device. Support for certificate- and password-

based authentication. Generates its own key with sshkeygen. SSH client functions are restricted to administrators with 

appropriate rights. Telnet client function to login/administer third party devices or other LANCOM devices from command line 

interface

Basic HTTP(S) file server

HTML pages, images and templates for Public Spot pages, vouchers, information pages of the Content Filter can be stored on a 

USB memory (FAT file system) in a specific folder as an alternative for the limited internal memory

Security

Access rights (read/write) over WAN or LAN can be set up separately (Telnet/SSL, SSH, SNMP, HTTPS/HTTP), access control list

Scripting

Scripting function for batch-programming of all command-line parameters and for transferring (partial) configurations, 

irrespective of software versions and device types, incl. test mode for parameter changes. Utilization of timed control (CRON) or 

connection establishment and termination to run scripts for automation. Scripts can send e-mails with various command line 

outputs as attachments

SNMP 

SNMP management via SNMP V2, new unified private MIB for all most current and future LANCOM devices with LCOS. Download 

link in WEBconfig

Timed control

Scheduled control of parameters and actions with CRON service 

Diagnosis

Extensive LOG and TRACE options, PING and TRACEROUTE for checking connections, LANmonitor status display, internal logging 

buffer for SYSLOG and firewall events, monitor mode for Ethernet ports

LANCAPI

Available for all LANCOM routers with integrated ISDN interface. LANCAPI provides CAPI 2.0 features for Microsoft Windows to 

utilize ISDN channels over the IP network

CAPI Faxmodem

Softmodem for Microsoft Windows that makes use of LANCAPI to send and receive faxes via ISDN

Statistics

Extensive Ethernet, IP and DNS statistics; SYSLOG error counter

Accounting

Connection time, online time, transfer volumes per station. Snapshot function for regular read-out of values at the end of a 

billing period. Timed (CRON) command to reset all counters at once

Export

Accounting information exportable via LANmonitor and SYSLOG
