When I configure my laptop to 10.137.32.146 and plug into int fa0/1, why can I communicate to whatever is plugged into 0/24, but cant ping the vlan ip address of .157?

When you say "Communicate" with any other device on 0/24 do you mean PING (ICMP)?

From what I can see your range of addresses within that VLAN should be 10.137.32.145 - 10.137.32.158 with .159 being the broadcast address. Layer 3 (routing) is enabled? I may be barking up the wrong tree but can you ensure that the VLAN is up.

what I can do is plug a synced up DSL modem into port 24, and my laptop into port 1.  the laptop is provisioned as 10.137.32.146 255.255.255.240.  I can authenticate a PPPOE session from my laptop to the internet and browse, but I cant ping my switch.  The end goal here is to serve some microwave equipment in the subnet you describe, and also be able to manage the switch itself.

Changed e0/24 to port-type nni and could ping it with ethernet configured in the subnet range, and still browse the internet with a ppp session on a different network.
