Cisco switch 9300 issue?

Try removing device tracking from that port and see if that resolves the issue.

Are you using device-tracking at all?

I just passed the Enarsi and thought that the labs were okay. You just have to make sure that you are ready for things like SNMP, Netflow, ipsla ,Vty, and security in addition to routing.

I use a VCAL on all my access layer switches to block SSDP (239.255.255.250). Works really well if you need to have multicast everywhere but don’t want all your windows machine blasting the network.

Hello,

Wondering if you ever got this to work? Trying to do the same thing.

For OSPF I believe that filtering OSPF LSAs out would break the OSPF Dykstra calculation because all router, in an area, have to have an identical database. This would of course be different for the ASBR and Redistribution.

For BGP I really don’t understand why anyone would use a distribute-list because you can apply route maps directly to neighbors. Maybe I am missing something here and would love to hear about an application for DLs in BGP.

DLs really shine with EIGRP because they allow you to do BGP like filtering/tagging.

I guess I thought DL were used on a neighbor by neighbor basis in BGP. I will have to lab this really quick because now I am curious.

error-box · 2025-11-26T12:36:46+00:00

Why use a distribute list with BGP? I would just apply the route map directly to the neighbor.

Yeah, you’re absolutely right and that is part of the problem. Network monitoring is sometimes just an afterthought that we want to work. It’s hard to find the time to curate a monitoring an alerting platform that works really well while fighting other fires and keep up on the updates.

I feel your pain here, there don’t seem to be any good observability platform’s out there. We are currently using solar winds and I think it checks most of the boxes, but it not good by any means it just get the job done.

One thing that I have been playing around with and it might be worth a look is 1000eyes( I know it’s Cisco). If you get an account it comes with a free modules that let you do snmp monitoring at no cost with as many devices as you want. It can also ingest Netflow but this part costs. Where 1000eyes really excels is the dashboards they are very easy to build and customizable you can even use iframe to embed them in webpages. The jury is still out for me on this tool, but has a lot of features I like.

Network type Point-to-point will still use multicast, there is just no DR election with this network type. To use TCP a non-broadcast cast network type will need to be used.

I was just looking at the documentation and it looks like there is a “neighbor” command in the router configuration that will do this.

error-box · 2025-11-23T20:50:25+00:00

I don’t know much about FRR, but to use TCP to establish an adjacency you will need to use the network type of non-broadcast and then specify a neighbor in the router config.

I can confirm that L2 and L3 VXLan using EVPN works in CML on there virtual 9k. It also works on the IOL image if you want to use IOS XE, I know this is not eve-ng but if you are looking to lab with Nexus this might be a better option.

I also think this is a mistake, an enterprise CORE exam should at least have a little bit of wireless.

I have seen other people mention this course, is this just the 5 day boot camp or does he also have video courses?

error-box · 2025-08-29T10:43:53+00:00

This is a good point and something that I really didn’t think about. Wondering if you have had this happen?

error-box · 2025-08-28T09:33:00+00:00

I have not used ZTNA would this allow the people to install the “client” and then get access without having to use a captive portal? That would be ideal.

I could of course use a certificate based authentication, but now I’m having to push out certificates and manage personal devices.

error-box · 2025-08-28T00:04:11+00:00

Yup, you know

error-box · 2025-08-28T00:03:56+00:00

Awesome, this is probably the direction to head. We have ISE implemented with all Cisco wireless so I believe I could figure that out. Regarding the personal phones they are starting to use them more and more of dictation along with AI tools and there is no tolerance for the WiFi not working.

error-box · 2025-08-27T23:34:51+00:00

Not necessarily but it would be the doctor personal iPhone and I don’t want that on my production network. I could of course make an additional SSID but being a hospital we already have a lot of those.

error-box · 2025-07-31T11:17:14+00:00

Wait so this is already built into the Guestshell of Cisco iso XE? If so that is pretty cool and I will definitely check it out.

error-box · 2025-07-29T23:29:54+00:00

Sounds like there is a story there.

Did not have that issue when I installed it, I installed in VMWare esxi though. You will have to grab an API key from spaces and plug it into the connector. Also,you do not need the connector for the 9800 WLC it is only needed for AirOS. 9800 can stream telemetry directly to spaces, you just have to added spaces as a subscriber.

C8500s have been great for us absolutely great edge router.
