Hi NetPro,
anyone who has the experience about the below logs ? i have configured the root bridge to the switch and HSRP configured as well.
Dec 12 15:40:24.556 CCT: %STANDBY-6-STATECHANGE: Vlan10 Group 1 state Standby -> Active
Dec 12 15:40:24.564 CCT: %STANDBY-6-STATECHANGE: Vlan10 Group 1 state Active -> Speak
your reply will be highly appreciated.
thanks.
regards,
jack

Hi,
Look at Sample Debug Output and Troubleshooting Procedure
Reference: http://www.cisco.com/en/US/tech/tk648/tk362/technologies_configuration_example09186a0080093f93.shtml
I hope this helps.
Best regards.

Hello Jack,
the local router has changed state from standby to active because it has missed three HSRP hellos from neighbor.
Then it receives again a better hello from the neighbor and it reverts to non active state
This can be seen sometimes for different reasons: the neighbor router cpu is high or the link is full. or the neighbor interface has flapped
Hope to help

Jack, it means that the routers running HSRP for this vlan experienced a change in state. The standby router went active, and then to speak.
Did the other router in the HSRP group fail? Is tracking enabled on an interface that may have gone down? Was another router added to the HSRP group?

Hi Victor,
both switches in the hsrp group. but, funny thing is only switch 1 had this logs . whereby sw 2 not even received any fail msg.
12-16-2008 03:03 AM
Hello Jack,
this means that only the local missed the other's switch hellos
no link faiure on the other device.
check the incoming traffic volume and if you have input errors of any type
Hope to help

Hi Qiuslar,
thanks for your information, what can i do after checking the input traffic volume ?
this logs show on the vlan10 having the flapping from Active->Standby.
your information will be helping me a lots.
thanks.

This HSRP member has changed from standby to active (means this was standby other was active), So if this is also active now can you check are both active for vlan 10?
If only one is active and one is standby for vlan 10 then you have just missed the error message on other switch.
Do you have only vlan 10 here or there are more vlan?
12-16-2008 06:16 AM
hi viyuan,
yes, this switch only contained 3 vlans (vlan 10, 20 and 30).
so, only sw 1 had received the Active->Standby logs. sw 2 has no suspicious logs shown.
so, now the sw 1 is standby and sw 2 is active.
thanks.

"These error messages describe a situation in which a standby HSRP router did not receive three successive HSRP hello packets from its HSRP peer. The output shows that the standby router moves from the standby state to the active state. Shortly thereafter, the router returns to the standby state. Unless this error message occurs during the initial installation, an HSRP issue probably does not cause the error message. The error messages signify the loss of HSRP hellos between the peers. When you troubleshoot this issue, you must verify the communication between the HSRP peers. A random, momentary loss of data communication between the peers is the most common problem that results in these messages. HSRP state changes are often due to High CPU Utilization. If the error message is due to high CPU utilization, put a sniffer on the network and the trace the system that causes the high CPU utilization.
There are several possible causes for the loss of HSRP packets between the peers. The most common problems are physical layer problems or excessive network traffic caused by spanning tree issues"
These error messages can be due to high CPU utilization or physical/spanning tree problem.
U can check CPU utilization?
What to check in physical problem see this link

sw 1:
193 state changes, last state change 5d19h
130 state changes, last state change 23:44:00
Sw2
23 state changes, last state change 1y1w
17 state changes, last state change 1y1w
Your switch 1 is changing state too much, can you check the followiong command for Sw1
show interface vlan10
show interface vlan20
show processes cpu
show ip interface brief
Also check the interface for errors to which this Sw1 is connected

193 state changes, last state change 5d19h
130 state changes, last state change 23:44:00
Vlan10 was changed 5d19h before
vlan20was changed nearly a day before.
Stable at this moment. Looks like you have to log CPU utilization high or errors when HSRP state change to troubleshoot it.
12-17-2008 10:52 PM
i just curious, vlan 10 and 20 were using for years, nobody has changed the configuration.
any possibilities reason ?
