Re: junos config commit question

[Nick Suan via NANOG <nanog () nanog org>]

I was actually interested to see if the EX series would let me do this, and it turns out that if STP is enabled on any 
of the switch interfaces, it won't: 


tevruden@core-02# delete interfaces 

{master:0}[edit]
tevruden@core-02# commit check 
[edit protocols rstp]
  'interface'
    XSTP : Interface ge-0/0/0.0 is not enabled for Ethernet Switching
error: configuration check-out failed
{master:0}[edit]
tevruden@core-02# rollback 
load complete

{master:0}[edit]
