Hi, The problem here is im not able to access 2 out of 5 vlans from my CE 500 switch .

All the vlans are configured in cisco 4506 core switch.

Whereas i am able to access all these Vlans in my cisco 2960 switch .

When i check the VTP status in CE 500 and cisco 4506 respectively the following is the output :

CISCO 4506 SWITCH

i couldn't see the domain name :nizwa in ur CE500, so can you configure that & giv the domain name & lemme know the feed back

hi , i just changed the vtp domain name to : nizwa .

After 30 secs the complete network went down .

i could not access the core switch 4506 console .

i had to restart both the switches to restore the network.

kindly revert. it s bit urgent

thanks ...

hey magesh,

assigning the vtp domain name nizwa to the client switch doesn't affect the entire network t go down, can you enable vtp transparent on the switches & send
