Clicking the Commit button applies any changes made on this page, but leaves the old
settings active until the next time the unit restarts. Clicking Make changes effective now
applies the changes and restarts SV1115IPEXT so the new settings take effect immediately.
Ethernet Address (MAC Address)
This is the Ethernet hardware address of this unit’s LAN/WAN port. It is set at the factory
and cannot be changed. You may need this number to configure your DHCP server.
Ethernet Bridging
When Ethernet bridging is enabled, the two Ethernet ports are virtually connected inside
the SV1115IPEXT. Packets arriving on either port that are not meant for it will be forwarded
out to the other port, when appropriate. IEEE-802.1d (“Spanning Tree Protocol”) is
implemented to avoid broadcast storms and to determine the topology of the network.
You may connect both the WAN and LAN ports to the same logical network through
redundant Ethernet switches. If one switch fails, the other will be used. When bridging
is enabled, both ports share the same configuration (DHCP or static IP addresses) and
the WAN port may not be separately configured. Using DHCP with Bridging increases
boot time, because the 802.1d (STP) algorithm must finish before the DHCP broadcast
can go out. To change this setting, select either Enabled or Disabled from the drop-
down menu and click Commit and Apply.
