Common external interface for the equipments is COM/Console/AUX port of the equipments Network: Server, Router, Bridge, Repeator, Switch Teleco: DSU/CSU, FLC, PBX, Media converters Power: UPS, Power Distribution Unit Controller: HVAC, Temperature control Remote Integrated Management over various equipments by using Console interface

  5. VTS Overview • Who need VTS? • IT professionals, Network administrators/managers • When is it useful? • Server crashes • Equipments is malfunctioning • Network is down • And more • Applications • Remote management of the IT/Telco equipments • Management of various equipments in IDC (Internet Data Center) • Management of co-location equipments • Server farm

  6. VTS Overview • Remote management over IT/TELCO devices • In-band access: LAN or Wireless LAN • Out-of-band access: dial-in access or broadband Internet access (ADSL/Cable) • User Interface • Intuitive Menu-driven console interface (System console/telnet/Web) • Linux Command-driven interface (Serial console/telnet) • Port functions • Port buffering (memory/ATA Flash) and Port sniffing • Multiple JTA support on web • PC Card support • ATA Flash card for the storage • LAN/WiFi/PSTN modem for the access • Security support • Authentication: SSH v1&v2, RADIUS, LDAP, TACACS+, (Kerberos) • User-level management: admin, port admin, user • IP filtering

  7. PCMCIA interface In-band management : Wireless LAN (802.11b) card Out-of-band management: PSTN/CDMA modem card Port buffering and configuration storage : ATA Flash card support RS232 console port connection Console port of the VTS In-band management : 10/100 Base-TX Out-of-band management: ADSL/Cable VTS Overview

  8. VTS Overview : Concept

  9. VTS Overview : Web interface

  10. VTS Technical Specification Embedded Connectivity

  11. VTS Technical Specification Embedded Connectivity

  12. VTS Technical Specification: PC Card support Ethernet ATA Flash Wireless LAN Modem Embedded Connectivity

  13. VTS Features & Benefits • Various Out-of-Band management support • PCMCIA interface • Wireless LAN, PSTN Modem, CDMA Modem • Protocols for directly connecting to Broadband Internet • ADSL/Cable • Secure management support • Security • SSH (Secure Shell) v2 • RADIUS accounting & authentication • IP-based packet filtering for preventing unauthorized access • Flexibility • Various combination of the system using PCMCIA support • e.g. ATA flash card with out-of-band management using ADSL • CDMA and LAN, PSTN and LAN, PSTN and ADSL/CATV and more • Price • Competitive price per port

  14. Internet Using the VTS and the application • Console server mode • Access the VTS serial port remotely using SSH/Telnet/Raw TCP VTS: 192.168.1.23 (211.134.23.10) Port: 192.168.1.23 (6001~6032) or 192.168.1.101~132 Out-of-Band In-Band Dial-in Remote PC Network Telnet/SSH Wireless LAN 192.168.1.21 192.168.15.56 210.34.111.9 Admin PC Remote PC Admin PC

  15. Using the VTS and the application • Port data logging NFS server or SYSLOG server Buffer size : Up to 3200KB in total System Memory Buffer size depends the server system Data stream Storage (ATA Flash card) Buffer size depends the memory space of the card Serial port Serial port

  16. Using the VTS and the application • Sniff mode • The VTS supports multiple users’ access over the serial port (sniff mode) • Sniff users’ right • Disconnect the session and make a main connection • Sniff data stream as an observer

  17. Using the VTS and the application • User authentication in access the serial port Local, RADIUS, LDAP, TACACS+, Kerberos

  18. Using the VTS and the application • Master/Slave clustering • One Master VTS can access Max. 16 Slave VTSs • Manage up to 544 serial port per Master

  19. Using the VTS and the application • Flash memory card configuration

  20. Using the VTS and the application • User Management

  21. Using the VTS and the application • VTS CLI • What is CLI? • Linux console (console, telnet/SSH) • Who can access the CLI? • Root user : All R/W • Admin user: Read-Only • What users can do thru CLI? • Edit VTS, Linux kernel configuration files • Run Linux command • Edit/Run Linux shell script • Run user program

  22. Using the VTS and the application • VTS utilities: • Editconf, saveconf, applyconf • Shell & shell utilities: • sh ash bash echo env false grep more sed which pwd • File and disk utils: • ls cp mv rm mkdir rmdir ln mknod chmod touch sync • gunzip gzip zcat tar dd df du find cat vi tail • mkdosfs mke2fs e2fsck fsck mount umount • System utilities: • date free hostname sleep stty uname reset • insmod rmmod lsmod modprobe • kill killall ps halt shutdown poweroff reboot telinit init • useradd userdel usermod whoami who passwd id su • Network utilities: • ifconfig iptables route telnet ftp ssh ping

  23. User Benefits • Maximize network efficiency & productivity • Remote Integrated Management over various equipments • Systematic approach • Always On-Line Management • Logging equipments’ messages to memeory • Delivery of equipments’ alarm messages by email • Delivery of the VTS log messages to syslog server or to NFS • Consistent management interface • Helps to forecast the problems by making various statistics data from the equipments’ log data • Reduce network down-time and Maximize network on-time • Reduce the total cost for the maintenance • Simplifies the maintenance by providing consistent management interface • Easier troubleshooting

  24. User Benefits • ROI(Return On Investment) calculation factor • User environment • Network Devices Server or the devices need to be managed • Cost: • Device Down Frequency/month • Average Up-time • Maintenance Labor cost • Number of the employee, percentage of the employee affected by the network down • Investment • VTS3200 1 unit for 32 devices • Result evaluation • Reduced network Down-time • Productivity of the employee work • Sales increase due to the improved network Up-time (On-line shopping mall)

  25. User application (Serial Communication) COM-Port redirector (Virtual serial port driver, Serial-TCP/IP conversion) 192.168.1.35 TCP/IP, Ethernet TCP/IP Serial Console port Ethernet 192.168.1.36 VTS Reference : Raw TCP • VTS Raw TCP mode and COM-port redirector Management PC COM11 : serial port on the PC HelloDevice VCOM Redirects COM11 data to the IP, 192.168.1.36 KT(Korea Telecommunication) DSU/CSU management IT/TELCO equipments
