Attribute Meaning
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.
