3.12 Checking the Status of the Uplink Port
This topic describes how to check the status of the uplink port to ensure that the interconnection
between the UA5000 and the upper layer device is in the normal state, thus ensuring the normal
communication.
Prerequisites
l The UA5000 must be powered on and must start working.
l The uplink port must be connected to the related upstream device, and the connection line
and the upstream device must work in the normal state.
Procedure
l When the independent upstream mode is used, proceed as follows:
– If the control board is PVMB, run the display fe command to check whether the service
uplink port (ETH1 port) on PVMB is in the normal state.
– If the control board is PVMD, run the display up-linkport workmode command to
check the type of the upstream service port, and then run the display fe command to
check whether the service uplink port on PVMD is in the normal state.
l In the integrated upstream mode, when checking the status of the internal communication
port, proceed as follows:
– If the control board is PVMB, and the upstream IPMB board is in slot 2, run the
display fe active ETH0 command to check whether the internal communication port
(port ETH0) between PVMB and IPMB is in the normal state.
– If the control board is PVMB, and the upstream IPMB board is in slot 3, run the
display fe active inner_FE1 command to check whether the internal communication
port (inner_FE1 port) between PVMB and IPMB is in the normal state.
– If the control board is PVMD, and the upstream IPMB board is in slot 2, run the
display fe active inner_FE0 command to check whether the internal communication
port (inner_FE0 port) between PVMD and IPMB is in the normal state.
