As it seems, the physical link is simply failing. Check cabling and connectors.
STP requires that you select the root bridge - it should be (one of) your most central switch(es). If you don't configure a root bridge it will be the switch with the lowest MAC address - essentially random.
A random root bridge that gets disconnected from the rest triggers a ...
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 ...
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-...
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 ...
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 ...
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 ...
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 22.214.171.124 255.255.255.0 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 ...
My list of tips would be:
make sure you have the right serial port (COM3), the right cable (blue Cisco - other brand will probably not work).
Connect to another cisco device, to make sure your cable, serial adapter and settings are working.
Set your speed to 115200. Lower speed communication will appear as garbage, but you will see something.
the ISP router needs to have a route to the 192.168.10.0/24 subnet via the RV320.
The RV320 needs a default route via the ISP router.
You need firewall rules in the RV320 permitting or denying communication between the VLANs and to/from the Internet. Note that as long as the ISP router is inside your LAN, your clients can just as well use that router.
The Cisco 2610 is not only end-of-life (in 2012) but it's also rated at just 20,000 packets/s, so there's little sense putting GE ports in it (there's only a 16-port FE module).
You seriously need to replace that router.
Is this possible or am I best off keeping these separate from my main network simply for learning purposes and upgrading to a Gigabit ...
I'd share my 2 cents about the above configuration. Single ASA & 2 routers might not be the ideal architecture. For the goal you're trying to achieve, most implementations involve 2 ASAs configured in active/standby mode as shown below.
You can easily punch a few Policy Based Routing commands and configure the interface path for certain source and ...
Holding the button in for 10 seconds or more is basically the same thing as performing a factory reset. I would hope somebody has the configuration backed up somewhere and can easily dump it back on the switch.
The software version that you are running on your WLC is not compatible with the 3700 series access points. You need to upgrade your code to at least 126.96.36.199 which is what Cisco indicates is the first version of code to support that AP platform.
You can find the compatibility matrix from Cisco here.
I want devices connected to VLAN 10 to have no ability to communicate with the internet or any other VLANs on the switch.
Simply do not connect a router to that VLAN. Each VLAN is a contained link-layer segment and without a router, that VLAN can't communicate with anything outside.
You can still trunk the VLAN across multiple switches without a problem.
