switchport community
community
Add port to community (port isolation group).
Ports within a single community can exchange traffic only
with each other and other unprotected ports (without
'switchport protected-port' setting).
- community: community name.
Restore the default value. In this case, protected port is an
isolated port (does not belong to any community), and it can
exchange traffic only with unprotected ports (without
'switchport protected-port' setting).
switchport protected
{gigabitethernet gi_port |
fastethernet fa_port |
port-channel group}
gi_port: (1..3/0/1..28);
fa_port: (1..3/0/1..24);
group: (1..8);
By default, routing is
performed via learnt MAC
address database (FDB).
Put the port into Private VLAN Edge mode. Disable the learnt
MAC address database (FDB) routing and direct all unicast,
multicast and broadcast traffic to the uplink port.
Enable the learnt MAC address database (FDB) routing.
