Can some one help me here if I am missing anything to check.
Our Palo Firewall got a vwire configured with interfaces eth1/5 & eth1/6.
eth1/5 is directly connected to eth1/2 of cisco switch and eth1/6 is directly connected to xe-0/0/1 of juniper router.
On switch eth1/2 flappings were observed (below are sample logs which were repeatedly seen for 6 mins) but firewall didn't log port going down, expectation here is firewall should log link down event as its other end of the link was down.
My question here is, are these below logs truly indicate that switch port physically went down or its just saying logical down but not physically down. are they any logs or commands i can run on switch to check whether switch port physically went down or not. On firewall we have this brdagent.log which shows logs for port power detection, do we have anything on switch to identify port power status??
only one interface in port channel and lacp here is in active mode
