mgmt interface on the 3750x connected to ASA

[talalaec02585]

Hello everyone! There is a small network, a Cisco ASA 5515-x edge device and two Cisco 3750-x switches. 

 icmp allowed on the ASA. Switch (1/0/48) connected to GigabitEthernet0/1 device ASA. The PC connected to the port 1/0/1 Switch1 is ping successfully from ASA. The management interface (vlan101) on the switch does no ping from ASA. The switch doesn't have any access list.
What could be the problem?

Hello

you have native vlan 101 in the switchport tunk however the sub-interface on the asa .101 isn’t native it’s tagged to vlan 101 so change the native vlan to 1 on the switchport and you should gain connection
