Appendix B: SNMP MIB Controls
Description of Figure B-1:
• Building #1 has one main network server that links all three floors together.
• Building #2 has one main network server with the network domain of 254.168.2.xxx.
Different methods of connection:
NOTE: Access control from the controller setup is disabled (allowing all access).
Connection within the same network domain. (Refer to the diagram above Building #1 in Figure B-1.) For example:
• The Ethernet PoE Gigabit Injector is connected to the network domain of 192.169.1.xxx located on the 1st floor. All computers
connected to the network domain of 192.168.1.xxx can communicate with the Ethernet PoE Gigabit Injector.
• The Ethernet PoE Gigabit Injector remains connected on the network domain of 192.168.1.xxx. Since Building #1 has a main
network server that links all three floors together, the computers on the second (192.168.2.xxx) and third (192.168.3.xxx) floors
can also communicate with the Ethernet PoE Gigabit Injector.
Connection between different network domains. (Refer to the diagram above Building #2 in Figure B-1.) For example:
• The Ethernet PoE Gigabit Injector is connected to the network domain of Building #1 (192.168.1.xxx) would like to communicate
with the Ethernet PoE Gigabit Injector from Building #1. Building #1 must configure the main network server to allow access
from an outside source, in this case Building #2. Building #1 must be able to support UDP port 161, for SNMP. Once the access
is allowed, Building #2 can communicate with the Ethernet PoE Gigabit Injector.
