interface down

[LizaRajjab]

Hi,

i have problem show interface down 

ethernet1/10            73    ukn/ukn/down(autoneg)

i can see error in brdagent logs as below.

anyone know what is reason this interface down?

Hi @LizaRajjab ,

What kind of device are you connected to on that port and is it copper/fiber? I would verify the cables and ports you are using are solid. Try swapping out cables and trying a different port.  Next, Id recommend verifying the connecting devices' speed/duplex settings to ensure they match what is configured on your Palo.

@LizaRajjab,

You can be a bit more precise by looking at power levels of the interface in the CLI using show transceiver-detail <interface> and taking a look at the Rx and Tx power levels. Generally when you see a port bounce like that it's going to be a layer1 issue, so once you've verified power levels verify connectivity between the PAN's interface and wherever it's actually connected.
