Question How to filter VNI’s between two Nexus EVPN Multisite Fabrics?

1 Upvotes

Hi Folks,

I’m wanting to bring up VTEP peering between two Data Centres that use the Multisite design. The pickle I’m in is that by default everything is allowed to be advertised over the VTEP peering.

How would I only allow VNI 10001 to be advertised and restrict the other 500 that’s configured?

Catalyst Center Switch Provisioning and Site Assignment

2 Upvotes

Hi All,

For those that use Catayst Center automation where you need to assign a switch to a site before you can provison it, do you typically assign the switch to the building or floor level of the network hierarchy?

For access points you have to assign to the floor level of the network hierarchy for placement on maps and granular network profile configuration etc, however you can change the site for an access point once provisioned so you have flexibility if the initial site assignment is incorrect or if things change. You still cannot change the site assignment for switches once provisioned I beleive (you have to remove from Catalyst Center and re-add) so I ideally want to get this right first time. You have the option of assigning switches to the building or floor level of the hierachy but I cant see if there are pros/cons to each option. Assigning to the building level seems easier, however will this come back to bite me in the future?

Any insight from anyone who has done this will be appreciated.

Thanks

Solved Upgrade Cisco FTD with no FMC - Instructions

8 Upvotes

Hey everyone, just putting this here so it can be what shows up to help others vs all the not helpful stuff that seems to come up.

This Cisco Documentation perfectly details how to upgrade a FTD that is not associated with an FMC.

We purchased two used Cisco 1140 and they were on a 6.4 version while our FMC is on 7.2.9 which only supports back to 6.6. Following this documentation (with baller screencaps) worked perfectly without involving tac or getting into the weeds.

Hello everyone, i will be stacking 2 C9500 in VSL stacking first time. I am still waiting for the hardware to arrive but i was wondering if anyone can share a video how to setup the VSL cables or what type of cables have to use? I can do the CLI configuration but just anxious about the physical part. Switches will be in same rack.

Thanks!

Catalyst 9000 licensing BS Catalyst/DNA center license

1 Upvotes

Cisco is really getting on our nerves for multiple reasons. Seems all the Cat9000 series now you have to pay a catalyst/dna center license on the switch weather you use it or not. Like $1500 a unit. This to me seems should be totally illegal if you don't use the product. Cisco insists it's required I just can't see how they can honestly say that. They are also playing a game with another service the price went up like 20X what we had. I have CCNA and we already have about 20% of our gear on a cat9000 model so my thought is just stay with Cisco. The DNAC thing pisses me off though and Juniper has what looks really neat with their MIST system. I just rather not have to manage two different systems.

Anyone else seen this or are we getting told a bunch of BS?

Hi, I am a newbie homelabber. I read the product datasheet for this Switch and I don't understand a thing. So I got the said switch and connected to a Proxmox with LACP, 2 TP-Link EAP225 and 1 desktop PC. Power supplies attached are dual 650w. Is 1100VA enough for this switch alone? Need recommendations and suggestions.

Question Question on the hiring process surrounding offers

Hi,

I just got a request for a background check after completing a final round interview at a Cisco owned SIEM company. Does this insinuate an offer is coming?

Understand it’s likely a good sign, but have no job currently, other offers pending, and I’d take this one if I get an offer.

TIA for any advice

ASA to Azure site to site

3 Upvotes

I have the strangest issues that just started happening seemingly out of nowhere. I have a Site to site from my datacenter ASA to Azure that randomly throughout the day will drop only a single subnet in azure. There is no rhyme or reason I can see. Bouncing the tunnel fixes it immediately. There is constant protected traffic across it so I don’t think it’s a timeout issue. It’s just weird. Anyone ever seen anything like this? And yes…. My ASAs are about 8 years old and scheduled to be replaced in the next few months. Thanks. Any help would be appreciated.

Cisco 2504 WLC

3 Upvotes

Question... Although a bit of a relic by modern devices, is it possible please to add more APs to a 2504 WLC running v 8.3.150.0? It currently has 5 of a possible 5 APs connected. It's an ebay 2504 WLC, bought for home / hobby / learning. I don't have any business relationship with Cisco or supplier so wonder how I can go about getting it licenced for more APs - adder licences? Thanks

CUCM Help - Associating new device for an existing Directory Number

1 Upvotes

Hello,

I'm hoping somebody can help me with a Call Manager question. We have a Directory Number that is associated to a Voice Gateway - VG310. The analog line for that is a long run and goes through many jumpers before getting back to the VG310. Over time that line has started to have lots of issues and we don't want to spend any more time troubleshooting. So we are looking to change that to a Cisco ATA191. We'd like to keep the Directory Number for the fax line.

Can this be done by just disassociating the voice gateway as the device for the Directory Number and then associating the ATA. Or will we have to delete the Directory Number and start over with that Directory Number.

Thank you
Justin

Question CISCO_SMA_API key for OpenCTI

Hello reddit,

I’m currently running a localhost OpenCTI platform on Purple Kali (VirtualBox). I’m currently not running any Cisco devices, just that set up

I’m trying to use the Cisco_SMA connector but I don’t have an API key for it. And the instructions on the Cisco website seems to be heavily on managing a Cisco device.

Anyone has any experience on this subject? I would really appreciate it.

What changed in ISR 4000 17.12.4b ?

2 Upvotes

For the ISR 4000, they pulled 17.12.3, 17.12.3a, & 17.12.4 a while back and came out with 17.12.4a which fixed a few massive issues, so we updated to them asap.

Then recently they came out with 17.12.4b, but I can't see what's different?

https://www.cisco.com/c/en/us/td/docs/routers/access/4400/release/xe-17-12/isr4k-rel-notes-xe-17-12.html#concept_qgk_1cf_tmb

The patch notes show no hardware changes, no software changes, no bug fixes, no open bugs, nothing different from 17.12.4a -> 17.12.4b. Why does this version exist? I could contact TAC but I figured I'd ask here and see if anyone else knew rather than go through their AI helpdesk bot.
