I've got a pair of hosted Cisco ASA 5525's in an HA pair that are being replaced. It's a bit of a weird situation because the hosting company owns the devices but they don't manage the devices. Because they don't manage the devices, they won't perf...

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...

Yeah, I think I'm just going to have to pay them to move the cable to the secondary and wipe them separately.

Appreciate the attempted assist but I get a [FAILED] error when I try that.ASA-Primary# failover exec standby write eraseErase configuration in flash memory? [confirm][FAILED]

Which would be a reasonable approach, but I actually only have access to 1 of the devices now. Just sort of a single patch into the primary device. Hosting company would probably charge me to move the cable to the secondary device too. So stupid t...

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.
