A layer-2 switch does not look at the layer-3 IP address on a packet to switch the layer-2 frames, and it only uses the MAC addresses on the frames for switching. The layer-3 interface on the switch is for switch management. It is like another host on the LAN, and it will not update its ARP table unless it communicates with a host at layer-3.
Switches use a ...

Perhaps you're familiar with physicist Richard Feynman explaining why he can't explain magnetism in some other way:
"I can't explain that attraction in terms of anything else that's familiar to you. For example, if I said the magnets attract like as if they were connected by rubber bands, I would be cheating you. Because they're not connected by rubber ...

Chances are that the given switch does not understand SNMP Community String Indexing and thus discards your SNMP request because of a "wrong" community string.
Still, your attempt at snmpwalk with an indexed snmp community string seems to be technically correct, according to the examples given at https://www.cisco.com/c/en/us/support/docs/ip/simple-network-...

Are these bytes or queues or potatoes? I couldnt find anyting online.
Cisco maintains documentation on its devices. For example, it took me about 30 seconds to find this by searching for cisco 3850 softmax buffer. I have higlighted the relavant text from Catalyst 3850: Troubleshooting Output drops:
The Default Buffer allocation for a 1GB port is 300 ...

Configuring a single router with OSPF does nothing but waste CPU cycles on a router. Routing protocols do not route, they exchange routing information with other routers running the same routing protocol.
Also, if all you have is a single network, then routing is completely unnecessary because routers route packets between networks, not from a network back ...

It is because you are dealing with ICMP which terminates at an interface on the Asa. In addition to your ACL, you need to permit to the interface with this command
“icmp permit 100.0.10.0 255.255.255.0 outside”
See cisco.com/c/en/us/td/docs/security/asa/asa-command-reference/… for full syntax.
Yes it is annoying that on the ASA you need to execute this ...
