I just re-certified with my CCNA yesterday and since I'm kind of used to sacrificing time to study to re-cert, I think now might be the best time to move onto CCNP. Everything I did for my CCNA studies I did in either Packet Tracer or in EVE-NG, but...

I'm doing some spanning-tree training and I'm wondering if it's possible, in the packet tracer software, to set the MAC address of a 3650 switch. I don't want to just set 1 interface, because I want to control (not via priority but via MAC address) ...

Hello Experts!I'm setting up a new vpn tunnel to a partner. ASA on our side Palo Alto on theirs. When the tunnel connects, it seems to run fine. However, should the tunnel go down, it will not come back up unless they initiate the traffic. They c...

I would like to setup sort of a single source of truth for time on the network. Our WatchGuard box at HQ already has pool.ntp configured on it and our servers are then getting NTP data from the WatchGuard. I'd like to also have the ASA 5525, who is...

We have a "critical security finding" even though our ASA SSLVPN web portal login page is shutdown on our ASA 5525. The "test" that is done is an http get is sent to https://<external IP>:443/+CSCOE+/logon.html and a response is returned. The respo...

True, I could just use the first few bits of the MAC and that's likely what I'll do since I can't adjust the MAC within packet tracer. Just IMHO but its still easier to see that AAAA is lower than BBBB or CCCC than it is to see that 0006 is lower th...

Yes, I'm aware. The point of the lesson is that, with all switches having the same priority, the MAC address is the tie-breaker for determining the lowest bridge ID.

Yes, I'm aware that I could adjust root bridge based on priority but this is for training purposes so I want the priorities to be the same. Just to make it easier for training, I would have liked to be able to set the MAC addresses to something like...

Thanks for your reply, perhaps you missed it but the issue has been resolved. There was a filter in AWS that was preventing my traffic from getting to the hosted PA.

Hello everyone. I do believe we finally have a resolution to the issue. It appears that the issue was twofold. One on my side and one on their side. From my side, this was a migration of a VPN tunnel with an existing partner. I completely forgot...
