I'm receiving packets from another switch in the lan ; (more than 15 switches) and one of them is using STP instead of RSTP (like all the other switches do). I saw this by using 'debug spanning general' on my catalyst:
06:23:30: RSTP(327): Fa0/48 rcvd STP BPDU, changing to STP modeHow can I check the source of this packet?
thank you.
