Oversized package
HI Guys,
i am facing an issue with a switch dell N1548, we have a separate network just for surveillance cameras and all our 160 ip cameras are distribuited in 7 switches of the the same model, all the Switchs trunk port are showing me oversized packed and some of them are dropping package, i checked each port connected the cameras and not seeing any problem, it seems the problem is when the pachage arrives at the trunk port and charge the MTU size of the pachage them the problem starts, any ideia what may causing this mtu change ?
ps. please check the attach to check the error.
bes regards,

Hi Daniel,
the Jumbo Frame was enabled before since it not worket i disabled it again, about the packet capture i do not tried yet and the firmaware is up to date, in those switches we have all IP cameras running over POE, so the size packet is the default 1500 MTU, the only problem shows in the trunk port i guess it change the header with the 4 bits for Vlan pachage so it means it change all pachage and the errors begin.
best regards,
