SNMP Connectivity Requirements
Some conditions must be met to set up the Constellation radio for SNMP
connectivity:
• A minimum of two subnets is required.
• If StarView or any SNMP management station is connected directly to
the Constellation Ethernet port, a 10BASE-T straight cable is required.
• An additional subnet is required for every enabled Ethernet port on a
remote radio. This is so accurate and reliable routing across the
Ethernet and Netcom interface can occur.
• Repeaters only require one IP address.
• For every site where the radio’s Ethernet port is enabled, the AUX port
must also be set to Ethernet.
• It is advisable to always enable RIP II on the radio.
• A reboot of the SPU shelf is required after any change to IP connectivity
information to enable the changes (non-traffic-affecting).
• Dual terminals require one IP address for each terminal.
• RIP II updates take a minimum of five minutes to broadcast updates.
Allow enough time for changes to broadcast across your network.
• If a router between the StarView PC and first radio is required, you may
need to enter static routes on the StarView PC to reach all Ethernet
subnets contained within the radio network.
