I'm new to Cisco switches.
I have a 3750 switch as the core switch and three 2960 switches, each with a separate VLAN. I made the DHCP and VTP settings and other basic settings. A firewall is connected to switch 3750 at 10.10.10.10. The problem I have is that I can't connect to the 2960 switches via SSH and TELNET. The code I used to set the switches is attached. When I turn on the IP assigned to the VLans, I connect to the core switch.
Please help me how can I connect to the 2960 switches via SSH and TELENT?
And if in the code, something is wrong and it might be better, please tell me.

Change the svi interface address of the 2960 switch, keep the svi ID consistent with the subnet used by the 3750. Add default-gateway config, then you can TELNET to the switch in any other subnets.
#2960 config int vlan 1 no ip address shut ! interface vlan 31 ip address 10.10.31.2 255.255.255.0 no shutdown ! ip default-gateway 10.10.31.1
