the ports i removed from the Default vlan, say 1,2,3 are masters in different lacp sharing group. I did not just lose connection via ssh... all servers connected to the switch, including the distribution switch it is uplinked to also did because those ports are tagged in different vlan. What I mean by "shutdown" is that connections were lost to the entire switch as soon as i effected this change << "configure vlan "Default" delete ports 1,2,3 >>
