SEM910
The SEM will report back the time it took to the save the information. Reset the SEM by typing:
reset<CR>
The SEM can also be reset by cycling power. Whenever a reset is executed on the SEM, the
telnet session will be lost. It will take the SEM about 30 seconds to reinitialize after a reset or
after cycling power.
Note: Failure to save and reset will result in the factory defaults being used.
Filtering
The SEM910 includes provision for filtering of multicast and broadcast packets. In many
networks, there is sufficient multicast and/or broadcast packets to slow the overall performance
of the SEM. Based on the number of broadcast and multicast packets, they can consume a
substantial amount of the RF bandwidth. By turning filtering on, the SEM will ignore these
packets and limit transmission to packets with specific device addresses. In some instances, it
will be desired to have the SEM transmit the multicast and broadcast packets; in this instance
filtering should be disabled. Note that filtering broadcast packets also filters multicast packets
but filtering multicast packets does not filter broadcast packets. To filter broadcast and multicast
packets use the bridge filter command:
bridge filter bcast<CR>
Refer to the section
Bridge Commands
for details of the filter commands.
DHCP
A DHCP server can set the SEM IP address as well as the default route IP address. This is
accomplished by setting the desired default route IP address in the DHCP server using Option 3.
A DHCP server will not overwrite a previously entered default router IP address in the SEM. If a
DHCP server is not used to set the default router IP address, one must be entered using the
route
command. See the previous section for details of the route command. If an IP address has
previously been entered into the SEM but a DHCP server is to be used to assign an IP address, it
will be necessary to set the IP address in the SEM to 0.0.0.0 using the
ip
command.
