I am looking for the Hybrid equivalent of NativeIOS's "no switchport"
command. First a historical example:
In Hybrid it is easy to get identical behavior when creating VLAN
interfaces at the MSFC. At layer-2 (CatOS) we'd enter:
set trunk 1/1 off
set vlan 111 1/1
and on the MSFC
int vlan 111
ip addr 1.1.1.1 255.255.255.0
To do the same thing in Native IOS the approx equiv would be
int gig 1/1
switchport mode access
switchport access vlan 111
int vlan 111
ip address 1.1.1.1 255.255.255.0
========
BUT: if we want to limit our STP instances, then we might do the following
in NativeIOS:
int gig 1/1
no switchport
ip address 1.1.1.1 255.255.255.0
So the question is: How would we achieve the same functionality in Hybrid
mode? Clearly we don't have any spanning tree BPDU's showing up on 1/1 in
this 2nd example, and all the other STP issues that come along.... so
there's good reason to want to do this [a pure layer-3 connection].... but
the only thing I can come up with in Hybrid would be the same as in example
#1 above, with a "clear trunk x/y 111" on EVERY other trunk interface....
What a pain! I can't find a global command which says "always remove VLAN
111 from any/every trunk interface".... so do y'all know of a command like
this, or a different method of achieving the same thing?
