I'm getting very scetchy results when attempting to perform layer 2 switching on my Cisco devices. I haven't tried with anything else yet.
I am attempting to configure a Spanning Tree / HSRP setup with a server on the access layer. I also tried with a vPC but am yielding the same results. In short, the mac-address table on my switches remains blank. I disabled ip routing and ensured the interfaces were up and that the vlans were properly tagged on each port but whenever I try to ping out, it doesnt even seem to try to leave the host machine (the VPC or server). I at first thought the issue was isolated to the VPC as I did for a short time manage to get HSRP / Spanning Tree to work and I even managed to get the core switches to ping eachother on their assigned VLAN IP. Saved the configs and stopping and restarting each node, they no longer can talk..
I decided maybe it was just an issue with my configs but I tried a similar setup in packet-tracer using layer 3 switches and it worked fine.
The switches are all L3 switches - using Cisco 3725's.
Here is my topology:
(ignore the two routers at the top, I removed the configs for those and decomissioned them from the setup, I just haven't updated the physical topology on those yet...all of the issues are happening L2) Here are my configs:
VPCS
Austin-CL-SW1:VPCS> ip 10.10.10.11/24 10.10.10.1

PC1 : 10.10.10.11 255.255.255.0 gateway 10.10.10.1
