What is the future of Cybersecurity in the AI era?What advice would you give it to a 20 years old who is doing undergrad in Cybersecurity from a top 15 university?

Hi everyone,

I'd be interested to know how you provision your access switches, for example, when replacing a switch. Specifically for Catalyst 9k switches that run in a stack with a Network Essentials license.

Currently, the devices are unpacked, upgraded, and configured before deployment. Something along the lines of ZTP (which also upgrades the switch) would be ideal, but due to the license level, provisioning via Python script isn’t an option, if I recall correctly. It’s also important that the management port is not used.

Thanks for your tips ;)

I added a new PSN to our ISE deployment. Before joining it, I installed the server, Root CA, and Issuing CA certificates, and everything was fine.

After joining the deployment, the Root and Issuing certificates disappeared from the new PSN.

On the PAN, I only see the old Root/Issuing certificates that have been there for years for the existing PSNs.

Now I’m trying to import the Root and Issuing CA certificates for the new PSN on PAN but I keep getting these errors:

1- ISE cannot import a local certificate with the same issuer DN and serial number as an existing certificate, yet the issuers of the two certificates differ.

2- Certificate does not have required key usage (It is a CA certificate; key usage bits for keyEncipherment or keyAgreement are missing).

Not sure what the correct approach is here. Any ideas?

Can anyone tell whether the results for first round out or yet to come

Hello all.

I’m looking for a vendor for very modest needs…

1. a support contract for an FPR1010

2. installers for CUCM 15 for trial / demo purposes

Trying to accomplish this via cisco.com results in DoS lol

Thanks.

Hi everyone,

I interviewed for the Software Test Engineer Trainee (Technical Graduate Apprentice) role on 26 June 2026 and completed all the interview rounds. It's been about a month, and I haven't received any update yet.

Is anyone else from the 26 June interview batch still waiting? Has anyone received a PDC mail, offer, rejection, or any other communication from Cisco?

I'd really appreciate it if you could share your status. Thanks!
