I need some help understanding my spanning tree results.I have 2 routers connected to each other, and 3 switches in a loop. So R3-SWA-SWB-SWC-R2 and back to R3.I have set R3 as the root with the lowest priority 8192 , R2 next lowest 12284, and switch...
I have a 9300x-12Y (R3) with 12 25g fiber ports and it has a C9300X-NM-8M network module with 8 multigig ports.I have a switch (SWITCHA) plugged into TE1/1/1 via copper which is trunked and working as normal.I plugged in another switch (SWITCHB) to f...
The basic oddity is that when I run show ntp status or show clock the time is 10 hours off, but some switches that sync with it are correct. Is this a display bug of some sort where it shows the wrong time, but is actually right?I have a 3850 and a 3...
I am seeing what appears to be a botnet (mainly Brazil IPs) trying to brute force connect to my ASA on port 443. Hundreds of thousands of attempts per day, but slow enough not to trip threat detection. Ive created a acl group to block control plane ...
I am attempting to change our service policy to allow us to bypass firepower inspection for certain traffic like VOIP. However, Im a bit confused as to the effect running certain commands would have. Someone else set this up a long time ago with the ...
Fun follow up. Came in this morning with fixed spanning tree paths and users were complaining about slow speed. I traced it a bad 10g fiber connection which was not being used because of the path cost was wrong. But now its right, but the cable is ba...
I think the issue may be R2 is using long path cost method instead of short. I dont have anything faster than 10g so is there any danger in changing it from long to short? Or better to change everything to long?
They are all layer 3 switches, yes. The two routers are layer 3 switches. Thats why the confusion. I did just move everything from PVST to rapid-pvst, Do I need to somehow force a recalc of the cost?I have several switches choosing the higher cost as...
