So in my network the computers and servers can ping the router and the router can ping them, but the switch can't ping the router

This is my switch

Here is your problem. You need to put a layer 3 (IP address) on Vlan 1 if your going to use that as your management vlan. Then you can either create another sub-interface on the router for vlan 1 or you can just put an ip address on fa0/0 on the router in the Vlan 1 subnet. In production I dont recommend using vlan 1 for management. If you do decide to change the native vlan then make sure you change it on the sub-interface on the router and also on the trunk port on the switch.


interface Vlan1
no ip address
shutdown

What would you recommend the IP address to be on vlan 1 then?

[auglan]

Whatever subnet you want for your management vlan.


Keeping with your ip scheme now:


10.1.3.0/24


Router interface:

10.1.3.1 255.255.255.0


Switch Interface:

10.1.3.2 255.255.255.0


Also don't forget to no shut the vlan 1 interface if you decide to use it.

Ok I did that and the switch still can't ping the gateway or the serial port on the router... but the computers and servers can. And I did the no shut command on the switch and the router.

even set the default gateway on the switch to see if that would work but nope nothing it can't ping the router.
