Hub is not receiving an SNMP frame.
In a stacked system where a Master and Slave agent exist, the SNMP LED of the active agent will blink if an SNMP frame is received. Normally, this would mean that the Master agent’s SNMP LED will be ON. However, if the Master agent fails, the Slave agent’s SNMP LED should light up. See the section on Master Agent in Chapter 4 for related information.
