2.5.14 Single IP
This switch provides a new management tool for user to manage a group of LAN switches by an IP
agent method. “Single IP” is the name, meaning that the administrator can access other network
devices through one single IP device. There are two management modes ,”Agent mode” and
“Stacking mode”, to utility the function.
Different from the method of router's NAT (from virtual IP domain to real IP domain), single IP provides a
reverse access (from real IP domain to virtual IP domain) by an IP-forwarding technology. With this
IP-agent method, network administrator can remotely control his far-side hosts without being there, for he
can access the private domain hosts through the agency of one real IP switch with “Single IP”.
There are maximum 32 sets of information of network devices stored in the single IP switch and 16
sets in Stacking switch. Basically these network devices should provide http or telnet service for the
single IP switch to forward those protocol packets; meanwhile SNMP protocol can be also passed
through if they support SNMP service.
More over, this single IP switch has no exclusiveness, meaning that administrator can group up
network devices of any type (router, switch, server...) or brand without worrying their incompatibility.
However, for stacking switch, only the switches of the same model can detect each other and transfer
information to their partner, so it won’t support other network devices. This is the major difference
between single IP agent mode and stacking mode. Please read Chapter 5 for more applications.
Web UIs of “Agent Management” and “Stacking Management” look similar. In these pages, user can
add or delete managed network devices here. If user disables the IP agent function, that is, he sets the
management mode to “Agent Slave” or “Stacking Slave” in the IP setting webpage, this item will not
show up in the main menu.
