Is there a cisco document that can help me identify closer the output of this command? For example, if I useSwitch#show controller ethernet-controller tw1/0/8 phyTw1/0/8 (if_id: 16)----------------------------------------------------00e0 : 1140 Cont...
Had an odd issue with VTP not passing on a trunk interface. All devices are on the same vtp domain.My VTP server is a 9606 VSS pair running 17.06.04. Have 100+ C9300 field switch stacks. Running either 17.12.04 or 17.03.05. I have a new C9606 VSS...
I have unexpected behavior from connected field devices. For redundancy, there are field devices that have two Ethernet ports and act as bridges. One port will be to my 9300 switch, second port to another field device, and daisy chain maybe two-fiv...
It is not listed as effecting 17.06.03, but I have two C9300-48UXM switches where this is affecting. Very infrequent. Switch#sho log | inc temp Apr 15 2023 19:46:28.305: %THERMAL-2-THERMAL_YELLOW_THRESHOLD: Switch 3 R0/0: cmand: Hotspot temperature ...
I have a C9500 setup as erspan-destination. I know it is receiving the traffic because as soon as I direct a erspan-source to it, the cpu process goes up. But the C9500 won't dump the traffic on to the destination port. I have a C9300 setup exactl...
I did run across a best practice somewhere that if not using it, disable it to close a potential security issue. I have had it disabled on all of my chassis for over three years. No issues.
I was able to update the 9606 to 17.15.04. I removed vlan 1 from the trunk and validated that VTP updates were still passing. So is definitely a bug with 17.15.01 in a very specific hardware configuration. But looking at my original post I see I n...
Sorry, C9300 series, mix of C9300-48U and 48UXM. 48U where we are limited to 10Mb since 48UXM can't go below 100Mb, or where we have an old rack that a 48UXM wouldn't fit in. This plant is only 75 years old.
Let me re-phrase. There is nothing wrong with the switch. This is a configuration issue I inherited. Many years ago (20+) the switch interfaces had to be hard coded because the field devices were not capable of auto-negotiation. Over time, many f...
