Cisco switch buffer size
WebDec 2, 2024 · A buffer, conceptually, is simply a place to store, or enqueue, data until it is transmitted out of the interface. On Catalyst 9000 Series Switches, the word buffer has two uses. The system buffer as a whole is otherwise known as the packet buffer complex (PBC) of the ASIC. The word buffers can also refer small unit of the PBC. WebThe problem with Cisco routers is that when you enable logging, the default size of the log is only 4096 bytes. With a log file this big it can typically only store about 60 messages. If your router is very busy these 60 messages will quickly scroll out of the buffer and be replaced by the next 60 messages of events going on with your router.
