Enable Management High Security Feature
This parameter is used to set the security level to either Low (unchecked) or
High (checked). A High security setting will block CLI and Web GUI modem
access, thus preventing unauthorized remote connections.
Caution: Once this parameter is enabled and activated in the modem, neither
the CLI nor the Web GUI can be used to disable High Security.
Disabling must be performed using the modem’s front panel.
Port Base
The Port Base sets the starting IP port addressing for all VMS messages.
Changing this address base will affect the entire network requiring configura-
tion changes to all modems. Leave this setting at default 49152 to avoid unnec-
essary configuration changes. Altering this setting is necessary ONLY if
network port addressing is in contention.
IP Address Mode
The SLM-5650A can be configured for either Single or Dual IP address mode:
• Choosing Single mode sets the modem to accept all traffic—data, VMS,
and management—that utilizes the Local IP Address of the Network
Processor card for this modem. The Management IP address is ignored.
• Selecting Dual mode requires that data and VMS traffic be directed to the
Local address, while CLI and Web GUI communications must utilize the
Management address of the NP card. This provides additional security for
remote connections.
Note that this mode is also utilized when operating in a redundant
configuration; both the online modem and the offline modem must be set
for Dual IP addressing. For more information on using the SLM-5650A in
redundancy configurations, refer to the pertinent redundancy switch
Installation and Operation Manual.
Specify the Local/Traffic IP Address and subnet mask to be used for the NP
card for this modem.
When using Dual mode, also specify an independent Management IP Address
and subnet mask to be used for the NP card for this modem.
Port VLAN
Enabling the Port VLAN feature assigns a specific Ethernet port on the SLM-
5650A for use by a specific VLAN independent of the user or system that is
attached to the port. All users attached to the port should be members of the
same VLAN.
