link aggregation down

[panos]

Hi,

We configured link aggregation but although switch side ports become up, on PaloAlto they are down.

Any idea ?

show interface ae1

Hi,

Could you please let me know what speed/duplex/state settings configured on S/W.

Thanks

I see : Configured link speed/duplex/state: auto/auto/auto

With Zone not configured you should see Runtime link speed/duplex/state: [n/a]/[n/a]/up, if the interface was UP.

Ethernet 1/21 and  1/22 seem to be SFP ports

Check if  similar behavior is observed on Non_SFP ports as well to rule out SFP issues.

Verify SFP compatibility . Ref :

Try to setup it manually on both sides (1000Mb/fullduplex).

In certain configuration it's helped me.

Hi Panos,

Ensure that we use static aggregation instead of using aggregation protocols like PAGP, LACP or GLBP on the swithces. PANFW only supports static aggregation.

Can you please share how the Issue resolved?

Hi,

They changed SFP type that used on PA and it worked.There was a mismatch of SFP types with switch.Thank you all for help.
