Hi

sh vlan
Status and Counters - VLAN Information
Maximum VLANs to support : 256 Primary VLAN : DEFAULT_VLAN Management VLAN :
VLAN ID Name | Status Voice Jumbo ------- -------------------------------- + ---------- ----- ----- 1 DEFAULT_VLAN | Port-based No No 50 PR_DC_TO_DR_DC_34_Mbps | Port-based No No 51 HRS_Ground_Floor | Port-based No No 52 SECRETARIAL_Depart | Port-based No No 53 Commerical_Depart | Port-based No No 54 Administrator_Vlan_54 | Port-based No No 55 ITS_SAP_CG | Port-based No No 56 Finance_Deaprt | Port-based No No 57 Marketing_Depart | Port-based No No 58 corporate | Port-based No No 100 dhun-ptp | Port-based No No All are working good without any issues. when i check the logs i see all lthe vlan going to disable state and then again getting enabled within sec. not sure what will be happening inthe environment. i am having all the access switches as HP 2626 and 2530.

Hi,
could you provide us more information? What version of STP are you running? Is anything changed in your global config (timer)? Do you have a root configured?
Could you post the first half (before the interfaces) of "show spanning-tree" show spanning-tree topo-change-history received show spanning-tree topo-change-history originated

Spanning tree version MSTP,no we have not done any changes to the STP configurations..we have not configured root.
what ever configuration came by default we are using the same.
