L4 Transporter

Hi All,

After deploying PaloAlto in VWire mode the router getting hanged,.. again after rebooting the router again works fine for hours and again gets hanged (Router have 1G interface).

We have set the negotiation to "Auto" in both PaloAlto and router.. Can any one provide the troubleshooting steps or resolution for this issue.

PANOS is 6.0.0

Model 2050

(as customer says the existing sessions works fine but problem will be with the new sessions ).

Thank you,

Gururaj

Hello Gururaj,

1. Do you have configured any aggregation protocol on your router..?

2. Could you please verify the packet rate on both PAN and the connected router.

3. Please verify the interface of the router, if any L2 error counters increasing rapidly.

Additional info: Re: Limits of VWIRE?

Thanks

is this happening random times after reboot ?

Do you have any asymmetric traffic ?

Hi panos,

After rebooting the router everything works fine for few hours and again gets hanged ( the existing sessions works fine but problem will be with the new sessions as customer says).

Symmetric traffic only.

Thank you,
