2.1.1.1 DHCP
The default DHCP is off, so Default IP or user defined IP is used when this machine is turning-ON, but if this
switch needs an IP assigned from DHCP server, user may click the square field and then press “ Apply “ to get
an IP which will be assigned by DCHP server “. User must be aware that if he enables DHCP from web page,
and if the DHCP server is working, then after enabling DHCP, he will lose contact of the web page, because
the IP address has been changed. At this moment, go through terminal mode and check configuration of
IP, then get Dynamic IP to return to web page.
2.1.1.2 Relocate HTTP port number
The default port number of HTTP command is 80, but unauthorized users may intrude this switch if he knows
the IP of this switch. Network manager may relocate this port number to other value, from 1024 to 65535, the
same idea as above, once network manager change the value of HTTP’s port number, he will lose contact and
he must regain web page by command modified as below:
http://192.168.1.100:port_value
2.1.1.3 Tag VLAN management group (CPU port)
At first time you turn on this device, all ports belong to default VLAN ID group (VID = 1), so they can
communicate to each other, and hence any port can be used as web management port to talk with CPU port
inside. But, for example, assume user uses port 1 as web management port, then user create VLAN ID = 10 on
port 7,8 and create another VLAN ID = 20 on port 5,6, now 3 VLAN groups will be shown on VLAN group table
after he press “ Apply “ button. If VLAN 10 and VLAN ID 20 must be isolated, then user must delete member
port 5,6,7,8 in default VLAN group (VID = 1). Be aware that CPU port still remains on VID = 1 group now, user
can only perform web management through one of 4 ports, that is port 1,2,3,4, but if user want to perform
web management from other port in existing different VLAN group, for example port 8 in VID =10, then
after creating new VLAN groups, he must go to system configuration page, and select Tag VLAN
Management Group to 10 by pressing “ Apply “ command, then move RJ-45 ( web management port )
from port 1 to port 8, then user can perform web management from new RJ-45 port again. But if user forgets
which group that CPU belongs to, there are two ways to solve this condition below.
(1) Through console port, check configuration of IP if he gets password
(2) Press “ Reset ” button few seconds , let system return to default settings, that is,
---- >> IP address = 192.168.1.100; … VID = 1, all settings return to factory default
