Please help to solve such case:
Host A is connecting to C2960 which is in turn connected to C4503.
A server is connecting to C4503 also.
Host A IP: 10.114.128.x /24
Server IP: 10.114.128.x /16
C4503 management IP: 10.114.128.x /16
C2960 management IP: 10.114.1.x /16
The whole network is using a flat Lan, i.e. one vlan.
Why Host A cannot access C2960 or C4503 but can communicate with server?
