How to Monitor Traffic on Cisco Nexus 3548 Switch

[JustinChitalian]

Hello,

I was wondering if there is a way to monitor the packets going through specific ports or IPs on the Switch.

MORE INFORMATION:
We have a PTP GM200 clock setup broadcasting a PTP signal at 192.168.1.231, we are using an Emergent Camera at 192.168.1.110 and we have our server at 192.168.88.11. The netmask for everything is 255.255.0.0. 
Everything is connected to a Cisco Nexus 3548 Switch.

We are experiencing an issue where the PTP stop receiving at the camera after about 172s after recording. 

So we were hoping to track the traffic between the camera and the PTP to see if we can see if we can capture any packet loss near the the time the PTP cuts out. 

THANKS!
