I have a Cisco 2950 switch. I am running a data and voice VLAN. I have my last 2 ports set for trunking and I am pulling both vlan information from a 3650 Switch. Right now all my data traffic goes Thurugh but not my voice vlan. Am I doing something wrong?

I need to run a “snake test” on a Cisco switch. Assuming I have 8 interfaces, how would I construct a configuration in Cisco IOS to perform a snake test? [In case you don’t know, a snake test is where you connect ports 2 and 3, ports 4 and 5, ports 6 and 7, with Ethernet cables and inject traffic into port 1 so that the packets will traverse the snake. Packets enter port 1, go out port 2 and into port 3, go out port 4 and into port 5, etc.
