Hi Parnassus,
Thanks for your response
All the switches (HP) are located at IDC in multiple racks and all are connected to the L3 Switch (Cisco)
All the switches (HP) are configured with multiple VLAN's and also configured the Trunk port on all switches to allowed multiple VLAN traffic.
When we are trying to Shutdown the one of the Switch, the Servers are also goes Down which are connected to the another switch
I dont know why this may happen and we are expecting that it is due to allowing of the multiple VLAN's traffic between switches and when we are trying to remove the trunk port the same issue occured again (Servers down at another switch).
Please suggest the recommendations to rectify this issue.
