Hi Guys,
I have ran in a wierd situation where my HSRP active router changed its state from ACTIVE to Speak with out any high priority box being introduced.
Logs

Can some one explain why did the Active Switch SW01 for VLAN191 went from active to speak mode while there was no change done in topology and all remains same.
