Is there something new that I do not know about with newer Cisco gear. In order to manage my switch I usually have to assign a VLAN 1 interface and add a default route (or ip default-gateway) to access other subnets.
I plugged this switch in and simply gave it a VLAN 1 IP address (10.0.0.50 255.255.255.0) and I can magically reach things out side of my subnet.
This is a cheap 2960:
EDIT, The config is as follows:

An example of a ping out of subnet:
ping 10.191.4.39
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.191.4.39, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/6 ms
Best Answer
A router attached to one of the switch's active interfaces is probably performing Proxy ARP. Lacking a routing configuration, your switch is broadcasting an ARP request for 10.191.4.39. That address isn't on the local segment, but your router knows how to reach it. The router running Proxy ARP replies to the switch to say, "I can reach that for you; send packets for that address to me." You can confirm this by examining the configuration on the router.
