We have around 16 switches(2 core (3560 and 14 * 2900 access switches) in network and all got hang for more then 20 mins.. we tried to connect through console of all switches but failed.. except 4 switches...
I checked the log of core switches and found conflict of HSRP ip for one VLAN.. there are around 20 L3 vlans interface/HSRP configured.
If it is due to HSRP conflict, will this cause all siwtches hang(hanged for more then 20 mins and came up after restart) except 4 access switches????
Plz let me know what all could be the possibilities...
I am also suspecting that there might be earting(power issue) which could cause switch in hang state but could not find any specific doc..
Is there any doc which can confirm that if there is power issue it can cause the switch in hang !!!!
