Attribute Meaning
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.
Point-to-Point Protocol over Ethernet (PPPoE)
PPPoE Point-to-Point Protocol over Ethernet: Used for Encapsulating PPP
frames inside Ethernet frames.
Service Name An optional entry to set a specific service name to connect to for the
PPPoE session. If this is left blank the SM accepts the first service
option that comes back from the Access Concentrator specified
below, if any. This is limited to 32 characters.
Access Concentrator An optional entry to set a specific Access Concentrator to connect to
for the PPPoE session. If this is blank, the SM accepts the first Access
Concentrator which matches the service name (if specified). This is
limited to 32 characters.
