How to troubleshoot Layer 2 related issues?

L4 Transporter

Hi,

I am a newbie here, How to troubleshoot Layer 2 related issues?  In a cisco switch, these counters are available for viewing,

1464790846 unicast packets  0 multicast packets  0 broadcast packets
1464790846 input packets  865795486189 bytes
9820 jumbo packets  0 storm suppression packets
0 runts  0 giants  0 CRC  0 no buffer
0 input error  0 short frame  0 overrun   0 underrun  0 ignored
0 watchdog  0 bad etype drop  0 bad proto drop  0 if down drop
0 input with dribble  0 input discard
0 Rx pause

How do I find these related matters on the Palo Alto Firewalls?

Thanks in advanced,

Ernest

Hi,

Thanks for the reply,

Our setup contains 2 10 gig ethernet ports which form the aggregated ethernet channel?  What is the best way to troubleshoot L2 issues in each 10 gig ethernet port?  How to identify if the ethernet ports are getting any L2 ethernet errors?

Thanks,

Ernest
