Hello, we are thinking we may be running up to this bug here on our core C1300 switches https://bst.cisco.com/quickview/bug/CSCwp39029The topology is that we have 2 Catalyst 1300's with an LACP between them, with multiple other Catalyst 9300 and 2960...
Hello, I am trying to help a new client resolve their VoIP issues of phones cutting in/out. The phones are Yealink phones and are connected to Catalyst 9200 switches, which then uplink to 2 core 1300 switches. Right now I have configured a separate V...
Hey folks I'd like some clarity on what exactly the option "Switchport Mode" means in the GUI config of a CBS250. Specifically it's on the "VLAN Management -> VLAN Settings" page. The options are either Layer 2 or Layer 3, with a default of 2. The he...

Our CPU input rate is always between 100-150pps. We actually RMA'd the original switch about a month ago, the replacement switch crashes too, except this time when it crashes even the console is not available. The switch must be physically hard unplu...
Glad you got your case solved, but we absolutely do not have any sort of configuration you mention (hosts using the switch as default gateway when the firewall is in the same subnet). Once again, we NEVER see CPU usage above 15%
Disabling STP is awful advice IMO..... to be honest I don't believe Cisco's assertion about CPU usage for a single second. If a switch falls over at 10% CPU USAGE, then it is a flawed device. Our own experience mirrors that of user Pieman, we never s...
