Protocols can describe low-level details of machine-to-machine interfaces (e.g., the order in which bits and bytes are sent across a wire) or high-level exchanges between programs (e.g., the way in which two programs transfer a file). Some protocols are IP, IPX, DECnet, AppleTalk, EtherTalk, SNMP, SMTP.

PT-MISM
SFP/XFP Port MISMatch. One of several alarm types that may be reported by a "show alarm" command on an ADVA RayExpress optical switch. The PT-MISM alarm is raised when a replaced device does not share the capabilities of the original device, or the alarm is raised when the data rate of a device will not support the service provisioned for that port. This alarm can happen because you are using a non-ADVA SFP or XFP. It's non-service-affecting, but you may want to clear the alarm by issuing a "initiate inventory sfp xxx" command (remember that the command will reboot the shelf processor, so you'll lose connectivity for 45 seconds or so, without affecting traffic).
