5.4.5 Administration - Management
5.4.5.1 Administration - Management – IP Configuration
The IP Configuration Page is used to configure the Ethernet interface and Management IP Connectivity.
Figure 52 – IP Configuration
(a) By default, management connectivity to a terminal is by fixed IPv4 address. The default IP address for
an “A” terminal is 192.168.0.21 and the default IP address for a “B” terminal is 192.168.0.22. Changes to
the IP address are protected by rollback which requires confirmation within expiry time limit, or else
changes will be rolled-back.
(b) If it is desired to set up a VLAN for management, this should be entered in the “Management VLAN Id”
box with a value from 1 up to 4095, and by setting the “Management VLAN Priority” with a value from
0 to 7. Management VLAN priority may take values from 0 to 7, with 0 being lowest priority, and 7
being highest. “DEI” stands for “Drop Eligible Indicator” within IEEE 802.1Q. The option “DEI Enabled”
sets the DEI Enabled bit, which indicates to other network devices (such as routers) that this VLAN has
low priority, and in case of system overload, these frames may be dropped to reduce congestion. If a
Management VLAN is entered, this will be enabled on pressing the “Apply” button: note that this is
likely to result in loss of GUI connection to the terminal, and the PC or router will need to be
reconfigured to use the same Management VLAN which has just been applied to the terminal. If VLAN
Filtering is enabled on GUI page “VLAN Config”, then it is important to make sure that both terminals of
the link are configured to use a VLAN for management, and this VLAN is listed in the “Allowed VLAN’s”
table.
(c) When DHCP is selected, the terminal’s IP Address, Subnet Mask and Default Gateway are acquired from
a DHCP server. When DHCP is selected these fields are greyed out. When using DHCP the terminal
cannot be managed until the DHCP client has started up and acquired an IP Address.
5.4.5.2 Administration Management – SNMP
The SNMP Configuration Page is used to configure the SNMP Agent, see below.
