Cannot disable vstack on switch

[CartoGraph]

Hello everybody,

I'm trying to disable at all vstack on a C3560 and the command "no vstack" doesn't work.

Does anybody know how to disable it? and close the port 4786?

PORT     STATE SERVICE
4786/tcp open  unknown

Switch(config)#no vstack
% Incomplete command.


Switch(config)#no vstack ?
  basic             Enable vstack director
  config            Configure default configuration file
  dhcp-localserver  Configure vstack dhcp parameters
  director          Configure director's IP address
  group             Configure a group for vstack
  hostname-prefix   Specify hostname prefix for Client
  image             Configure default image file
  join-window       Configure time interval to enable director
  vlan              Configure vstack management vlan

Thank you!!!

ranjit123-
You need to apply the ACL blocking the port on VLAN1. Documentation in this thread shows an example. NOTE that if you have an older version of IOS that has VSTACK there, but not able to be disabled, the blocking of the port with the ACL is your only option, SHORT of upgrading your device to a newer IOS that actually has the DISABLE command.

hi, I applied in all interfaces but still showing listening

SW#show tcp brief all | i 4786
049772BC *.4786 *.* LISTEN

this worked for me.

the switch still listens for TCP 4786, but it's closed/no response when i tried to telnet 4786.

#show tcp brief all | i 4786
0355FD0C *.4786 *.* LISTEN

Restart and Use the command "no vstack" or "no vstack config" to disable Smart Install.
