FlexBus 1500 Management Link

The management link in a chain of cascaded hubs must be connected to manage the stack as a single unit. This means that only hubs connected using the FlexBus 1500 can be controlled by an SNMP management agent. At most, 10 hubs can be managed and linked together using the FlexBus 1500 connection.

Hub ID Setting

In a stacked system, each hub should have a unique ID number to identify itself. The EtherHub-16i+automatically sets its Hub ID if attached to an SNMP management agent (EtherHub-16mi+) through the FlexBus 1500 port. However, for this automatic function to work, the Hub ID Setting before connecting to the agent should be set to the factory default (i.e., automatic hub

ID generation; where all Hub ID LEDs are blinking). When

the stack includes a EtherHub-16mi+, you can also select hub IDs using the EtherHub 1500 System Configuration Program via out- of-band or with AccView/Open via in-band communication.

Refer to Hub ID Setting in this chapter for more information.

ΦIf the Hub ID of EtherHub-16mi+is set to factory default (i.e, 0000), it will automatically set/change this ID number to 1 when used in a stand-alone configuration.

SNMP Backup Agent

The EtherHub 1500 system supports a management agent backup function. This special function allows the hub stack system to have two SNMP network management agent devices, wherein one agent is configured as a Master agent and the other as a Slave (Backup) agent. Normally, the agent in slave mode behaves as an EtherHub-16i+, but if the Master agent fails, the Slave agent takes over its functions. The data stored in the
