• L2 QoS (Layer 2 QoS) – Use the drop-down list to select this feature as Off, VLAN only, Port
only, or VLAN & Port.
L
L2 QoS can be enabled only when the optional IP Packet Processor is disabled.
• Dedicated Management Port – This feature is available in Managed Switch Mode, but it is
unavailable when VLAN Mode is Enabled or when the optional IP Packet Processor is
enabled.
Use the drop-down list to select Port 1, Port 2, Port 3, or Port 4 as the Dedicated
Management Port. If Port 1 (2,3,4) - Local Only is selected, management is restricted to LAN
only. Note that, when the optional IP Packet Processor is Enabled, the drop-down list
displays Disabled as the sole listed option. When VLAN is Enabled, the drop-down list
displays all options as described previously, but the selections are non-functioning.
• 2048 Ethernet Frame Size – This feature is supported only on modems with Hardware
Revision 2.X or higher.
Use the drop-down list to select this feature as Disabled or Enabled.
• IP Gateway (applicable only in Managed Switch Mode), and Traffic/Mgmt IP Address (and
subnet mask) – Configure the modem’s IP Addresses using these fields.
• MAC Learning (applicable only in Managed Switch Mode) – Use the drop-down list to select
MAC Learning as On or Off.
• L3 QoS (Layer 3 QoS) – This feature is operational only when the optional IP Packet
Processor card is installed and enabled.
Use the drop-down list to select the L3 (Advanced) QoS as Off, Max/Priority, Min Max, or
DiffServ.
• Working Mode – Use the drop-down list to select the Working Mode as follows:
o Managed Switch – Primarily intended for operation in a point-to-point topology,
Managed Switch Mode is Comtech’s IP modem intelligent networking solution. It allows
a link to be set up with minimal configuration (no specific routes need to be configured).
When the optional IP Packet Processor is either not installed or is installed but
disabled, Managed Switch Mode provides support for Layer 2 QoS, and Dedicated
Management Port or VLAN.
When the optional IP Packet Processor is installed and enabled, advanced features are
available, such as Layer 3 (Advanced) QoS, Header and Payload Compression, Streamline
Encapsulation (SLE), and Encryption. Most are supported only under “Admin” user
access.
