JBoeldt · November 28, 2018, 5:17am

The SM’s Network page is used to configure system networking parameters and VLAN parameters. Parameter availability is based on the configuration of the SM Network Page for Bridge Mode.

Attribute	Meaning
General
Network Mode	NAT: The SM acts as a router and packets are forwarded or filtered based on their IP header (source or destination). Bridge: The SM acts as a switch and packets are forwarded or filtered based on their MAC destination address. Router: The SM acts as a router and packets are forwarded or filtered based on their IP header (source or destination) using specific static routes and IP aliases configured by the operator.
IP Assignment	Static: Device management IP addressing is configured manually in fields IP Address, Subnet Mask, Gateway, Preferred DNS Server and Alternate DNS Server. DHCP: Device management IP addressing (IP address, subnet mask, gateway, and DNS server) is assigned via a network DHCP server, and parameters IP Address, Subnet Mask, Gateway, Preferred DNS Server and Alternate DNS Server are unused.
IP Address	Internet protocol (IP) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network. Note If Device IP address Mode is set to DHCP and the device is unable to retrieve IP address information via DHCP, the device management IP is set to fall back to IP 192.168.0.1 (AP mode), 192.168.0.2 (SM mode), 192.168.0.3 (Spectrum Analyzer mode) or the previously-configured static Device IP Address. Units may always be accessed via the Ethernet port with IP 169.254.1.1. 169.254.1.1 is a local IP and is independent of the NAT local subnet or the wireless IP.
Subnet Mask	Defines the address range of the connected IP network. For example, if IP Address, Subnet Mask, Gateway, Preferred DNS Server and Alternate DNS Server are configured to 255.255.255.0, the device will belong to subnet 192.168.2.X.
Gateway	Configure the IP address of a computer on the current network that acts as a gateway. A gateway acts as an entrance and exit to packets from and to other networks.
Preferred DNS Server	Configure the IP address of the preferred server used for DNS resolution.
Alternate DNS Server	Configure the IP address of the alternate server used for DNS resolution.
IPv6 Assignment	IPv6 Assignment specifies how the IPv6 address is obtained. Static: Device management IP addressing is configured manually in fields IPv6 Address and IPv6 Gateway. DHCPv6: Device management IP addressing (IP address and gateway) is assigned via a network DHCP server, and parameters IPv6 Address and IPv6 Gateway are unused. If the DHCPv6 server is not available previous static IPv6 address will be used as a fallback IPv6 address. If no previous static IPv6 address is available, no IPv6 address will be assigned. DHCPv6 will occur over the wireless interface by default.
IPv6 Address	Internet protocol version 6 (IPv6) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network. IPv6 addresses are represented by eight groups of four hexadecimal digits separated by colons.
IPv6 Gateway	Configure the IPv6 address of the device on the current network that acts as a gateway. A gateway acts as an entrance and exit to packets from and to other networks.
Ethernet Port Security	Disabled: When disabled, any number of devices (MAC Addresses) can connect via the SM’s Ethernet (LAN) port. Enabled: When enabled, the number of devices (MAC Addresses) that can connect via the SM’s Ethernet (LAN) port can be restricted with the fields below.
Secure MAC Limit	Specify the maximum number of unique devices (MAC Addresses) that can connect via the SM’s Ethernet (LAN) port. Range is 1 – 254 devices.
MAC Aging Time	Specify the aging timer in seconds. The aging timer will determine the duration for which the SM will maintain the MAC Address in its bridge table. The timer is restarted any time traffic from a specific MAC address is received on the LAN port. Once the timer expires, the MAC Address is removed from the SM’s bridge table.
Virtual Local Area Network (VLAN)
Management VLAN	Enabled: The SM management interface can be assigned to a Management VLAN to separate management traffic (remote module management via SNMP or HTTP) from user traffic (such as internet browsing, voice, or video). Once the management interface is enabled for a VLAN, an SM’s management interface can be accessed only by packets tagged with a VLAN ID matching the management VLAN ID. A VLAN configuration establishes a logical group within the network. For the network operator, this provides flexibility in network segmentation, simpler management and enhanced security. Disabled: When disabled, all untagged IP management traffic is allowed to the device.
Management VLAN ID	Configure this parameter to include the device’s management traffic on a separate VLAN network. For example, if MGMT VLAN ID is set to 2, GUI access will only be allowed from frames tagged with VLAN ID 2. This parameter only takes effect if the MGMT VLAN parameter is enabled.
Management VLAN Priority	ePMP radios can prioritize VLAN traffic based on the eight priorities described in the IEEE 802.1p specification. MGMT VLAN Priority represents the VLAN Priority or Class of Service (CoS). Operators may use this prioritization field to give precedence to device management traffic. This parameter only takes effect if the MGMT VLAN parameter is enabled. Configure this parameter to set the value of the Priority code point field in the 802.1q tag for traffic on the management VLAN originating from the SM. The default value is 0.
Data VLAN	Enabled: A VLAN tag will be added to all untagged traffic entering the SM’s LAN port before sending it to the AP and remove tags in the opposite direction from traffic (tagged with Data VLAN ID) entering on the SM’s WAN port before sending to the SM’s LAN port. Disabled: When disabled, no changes are made to untagged traffic passing through the SM.
Data VLAN ID	Configure this parameter to include this VLAN tag to all untagged traffic entering on the SM’s LAN port before sending it to the AP and remove tags in the opposite direction from traffic (tagged with Data VLAN ID) entering on the SM’s WAN port before sending to the SM’s LAN port.
Data VLAN Priority	ePMP radios can prioritize VLAN traffic based on the eight priorities described in the IEEE 802.1p specification. Data VLAN Priority represents the VLAN Priority or Class of Service (CoS). Operators may use this prioritization field to give precedence to device user data. This parameter only takes effect if the Data VLAN parameter is enabled. Configure this parameter to set the value of the Priority code point field in the 802.1q tag for traffic on the Data VLAN originating from the SM. The default value is 0.
Membership VLANs	Configure the Membership VLAN Table to include the SM in one or more VLANs. When the SM receives a packet tagged from either the Ethernet (LAN) or Wireless (WAN) side with a VLAN ID which is contained in the Membership VLAN Table, the packet is forwarded and sent out the other interface. When the SM receives a packet tagged with a VLAN ID which is not present in the Membership VLAN Table, the frame is dropped (assuming there is at least one VLAN ID present in the Membership VLAN table or configured as a Data VLAN).
VLAN ID Begin	Configure the first VLAN ID for the VLAN range.
VLAN ID End	Configure the last VLAN ID for the VLAN range.
VLAN Mapping	Configure the VLAN Mapping Table to map the C-VLAN of traffic ingressing the Ethernet (LAN) port of the SM to a S-VLAN before being forwarded to the air interface on the UL. In the DL direction, the SM will automatically un-map the S-VLAN to the C-VLAN before forwarding the tagged packets to the Ethernet (LAN) interface of the SM.
C-VLAN	Configure the C-VLAN ID of the tagged traffic for which the mapping needs to occur Note The C-VLAN ID must be entered in the SM VLAN Membership VLAN table.
S-VLAN	Configure the S-VLAN ID to which the tagged traffic needs to be mapped to. Note The S-VLAN ID must be entered in the SM VLAN Membership VLAN table.
Ethernet Port
Ethernet MTU	Maximum Transmission Unit; the size in bytes of the largest data unit that the device is configured to process. Larger MTU configurations can enable the network to operate with greater efficiency, but in the case of retransmissions due to packet errors, efficiency is reduced since large packets must be resent in the event of an error.
Ethernet Port	Disabled: The primary Ethernet port is disabled Enabled: The primary Ethernet port is enabled
Port Setting	Manual: The LAN Ethernet port speed and duplex mode can be manually configured. Auto-negotiate: The AP auto negotiates the LAN Ethernet port speed and duplex mode with the device connected to it.
Port Speed	With “Ethernet Port Configuration”, the LAN Ethernet port speed can be forced to 1000 Mbps (only GPS Sync’d radio), 100 Mbps or 10 Mbps.
Port Duplex Mode	With “Ethernet Port Configuration”, the LAN Ethernet port duplex mode can be forced to Full or Half.
Auxiliary Port	Disabled: When disabled, the LAN Auxiliary port on the SM is shut down. Enabled: When enabled, LAN Auxiliary port on the SM is up and able to bridge traffic with the primary Ethernet port. Default value is Enabled.
Auxiliary Port Setting	Manual: The LAN Auxiliary port speed and duplex mode can be manually configured. Auto-negotiate: The AP auto negotiates the LAN Auxiliary port speed and duplex mode with the device connected to it.
Auxiliary Port Speed	With “Auxiliary Port Configuration” set to Manual, the LAN Auxiliary port speed can be forced to 1000 Mbps (only GPS Synchronized radio), 100 Mbps or 10 Mbps.
Auxiliary Port Duplex Mode	With “Auxiliary Port Configuration” set to Manual, the LAN Auxiliary port duplex mode can be forced to Full or Half.
Auxiliary Port PoE	Disabled: When disabled, the LAN Auxiliary port on the SM will not provide proprietary PoE out. Default value is Disabled. Enabled: When enabled, LAN Auxiliary port on the SM will provide proprietary PoE out to power external PoE devices such as another ePMP radio or a PoE camera.
Broadcast/Multicast Traffic Shaping
Broadcast Packet Limit	Enabled: This allows the user to set the Broadcast Packet Rate below. Configure this parameter to limit the amount of broadcast packets that will be allowed on the ingress of the radio’s Ethernet port. Set the packets per second value to limit the impact of events such as broadcast storms. Disabled: There is no limit on the amount of broadcast traffic that will be allowed into the ingress of the radio’s Ethernet port.
Broadcast Packet Rate	Set the packets per second value to limit the amount of broadcast traffic that will be allowed on the ingress on the radio’s Ethernet port. The packets per second limit can be set individually on each ePMP radio. The range is 100 to 16000 packets per second. The default is 1000.
Multicast Group Limit	Configure the maximum number of simultaneous multicast groups that the SM will allow from devices below it. The default is 3.
Multicast VLAN	Enabled: A VLAN tag will be added to all untagged multicast traffic entering the SM’s LAN port before sending it to the AP and remove tags in the opposite direction from traffic (tagged with Multicast VLAN ID) entering on the SM’s WAN port before sending to the SM’s LAN port. Disabled: When disabled, no changes are made to untagged multicast traffic passing through the SM.
Multicast VLAN ID	Configure this parameter to include this VLAN tag to all untagged multicast traffic entering on the SM’s LAN port before sending it to the AP and remove tags in the opposite direction from multicast traffic (tagged with Multicast VLAN ID) entering on the SM’s WAN port before sending to the SM’s LAN port.
Multicast VLAN Priority	ePMP radios can prioritize VLAN traffic based on the eight priorities described in the IEEE 802.1p specification. Multicast VLAN Priority represents the VLAN Priority or Class of Service (CoS). Operators may use this prioritization field to give precedence to device multicast data. This parameter only takes effect if the Multicast VLAN parameter is enabled. Configure this parameter to set the value of the Priority code point field in the 802.1q tag for traffic on the Multicast VLAN originating from the SM. The default value is 0.
Advanced
Spanning Tree Protocol	Disabled: When disabled, Spanning Tree Protocol (802.1d) functionality is disabled at the SM. Enabled: When enabled, Spanning Tree Protocol (802.1d) functionality is enabled at the SM, allowing for the prevention of Ethernet bridge loops.
DHCP Servers Below SM	Disabled: This blocks DHCP servers connected to the SM’s LAN side from handing out IP addresses to DHCP clients above the SM (wireless side). Enabled: This allows DHCP servers connected to the SM’s LAN side to assign IP addresses to DHCP clients above the SM (wireless side). This configuration is typical in PTP links.
NAT Helper For SIP	Disabled: When disabled, the SM does not perform any deep packet manipulation on the SIP request packet from a SIP Client. Enabled: When enabled, the SM in NAT mode replaces the Source IP within the SIP request to the Wireless IP of the SM. Please note that this translation is often times handled by the SIP server so this option may not always be needed.
LLDP	The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol (as specified in IEEE 802.1AB) used by ePMP for advertising its identity, capabilities, and neighbors on the Ethernet/wired interface. Disabled: ePMP does not Receive or Transmit LLDP packets from/to its neighbors. Enabled: ePMP can Receive LLDP packets from its neighbors and Send LLDP packets to its neighbors, depending on the LLDP Mode configuration below. Note LLDP packets are Received/Transmitted ONLY to the neighbors on the Ethernet Interface of the ePMP radio.
LLDP Mode	Receive and Transmit: ePMP sends and receives LLDP packets to/from its neighbors on the Ethernet/LAN interface. Receive Only: ePMP receives LLDP packets from its neighbors on the Ethernet/LAN interface and discovers them.
