I have a problem with some switchs in the Campus.
the iphones lose connection with the callmanager and the connection between a Laptop and the switch also lose ( no ping to ip address for int vlan).
This disconnection is about 3 minute.
In the moment of the problem , I connected to the switch by console and I get this result of show-techsuport ( attached).
Please can someone see the show tech and help me to know the source of problem
Thanks in advance
