4.2.4 Setting the number of users who can simultaneously log in
The number of users who can simultaneously log in to the router can be changed
using a configuration definition command (CLI type 1) (router) (see Configuration
Guide, router). However, notice that the number of users who can log in using a Web
browser cannot be changed. An example of a setting is shown in the figure below.
Figure 4-5 Setting the number of users who can simultaneously log in
An overview of operation of simultaneous login is described below.
A The message "Sorry, too many users are logged in" is displayed on the screen
when the user logs in when the numbers of users who can simultaneously log in
has reached the maximum. (This message may not be displayed depending on
the state of the network). In this case, login will fail.
When two or more users simultaneously log in, they may not be able to log in
even if the number of users who log in is less than the number of limited users.
When a dial-up PPP connection is made using a modem (see Section 4.8 "Setup of
Dial-Up Networking with Remote Operation Terminal"), users connected for PPP
connections are not counted in for the number of login-user accounts.
Even if number of users who log in simultaneously is changed, session of users
which already logged in remains connected.
4.2.5 Limiting login from a remote operation terminal
Login from a remote operation terminal to the router can be limited by the setting
below. After setting, confirm whether to log in from the remote operation terminal to
the router.
4.2.5.1 Setting an IP address permitting login
The IP address of a terminal that in advance permits access using a configuration
definition command (CLI type 1) (router) (see Configuration Guide, router) must be
registered to enable access from the remote operation terminal to the router. A
maximum of 128 IPv4 addresses and subnet masks, or IPv6 addresses and prefixes
that permit an access can be registered. For access from the terminal (not registered
using configuration definition information) that permits no access, an "Unknown
host address <IP address>" message indicating the existence of access is displayed
on other terminals which are already logged in.
