Interface Status

ATM Status The Interface Status screen provides real-time information about the interfaces. To bring up this screen, from the OfficeConnect Remote 840 Manager home page, select Monitor > Interface Status. ATM interface information is displayed in the row containing the interface name atm:1 or hdlc:1.

The Oper Status column indicates whether the interface link is operationally up or down. If it is down, there may be a cabling problem. The Admin Status is set to up by default. If this field says down, then the interface has been disabled by a user and will not operate until it is re-enabled. Use CLI to enable or disable the operational state.

ATM Cell Status You can view real-time cell status from the ATM Status screen. To access this screen from the OfficeConnect Remote 840 Manager home page, select Monitor > ATM.
