Cant access my management VLAN address of my switch

[hshabany]

We have purchased a Cisco 3650 switch. The switch is working fine and I can access it through an IP address in the default VLAN but I am unable to access it through out management VLAN (254). I have 4 other Cisco 3560 switches that I can access just fine through 254 VLAN. I have allowed the 254 VLAN in the trunk but that didn't help. I am not sure what I am missing here.

FYI - The line protocol is down on vlan 254 for the access switch, so adding a default static on the core won’t make any difference and will have no bearing on inter-lvan communication as ip routing is already enabled
