Would someone mind letting me know what L2 protocols run on a Cisco switch by default. (.e.g CDP, STP, DTP) I need to build an exhaustive list of all L2 protocols.
Thank you very much
It's really going to depend on the model and software version of the switch. CDP and STP are both enabled on all switches that I can think of. As for DTP, it depends on the switch. Also, the version of STP running on the switch by default will depend on the model and software version of the switch.
