66  MES3000 Ethernet switch series 
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 |

port-channel group} 
gi_port: (1..8/0/1..24);  
te_port: (1..8/0/1..4); 
group: (1..24); 
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. 
ip internal-usage-vlan vlan_id 
vlan_id: (1..4094)/no 
reserve 
Reserve VLAN for internal use on the interface. 
no ip internal-usage-vlan 
switchport default-vlan tagged 
Define the port as tagging in the default VLAN. 
no switchport default-vlan 
tagged

Table 5.38 —Global configuration mode commands 
Enter the VLAN configuration mode. 
default interface {vlan vlan_id 
| range vlan vlan_list} 
vlan_id: (1..4094); 
vlan_list: (1..4094) 
Resets  configuration  of  a  VLAN  interface  or  a  range  of  VLAN 
interfaces to default. 
- vlan_id – VLAN ID 
-  vlan_list  –  list  of  VLAN  IDs  To  define  VLAN  range,  enter  values 
separated by commas or separate starting and ending values with 
a hyphen '-'.
