VLANs 
RS400 
179 
ROS™  v3.5 
The VLAN Identifier is used to identify the VLAN in tagged Ethernet frames according to IEEE 
802.1Q.  
VLAN Name 
Synopsis: Any 19 characters 
Default:  
The VLAN name provides a description of the VLAN purpose (for example, Engineering VLAN). 
Forbidden Ports 
Synopsis: Any combination of numbers valid for this parameter 
Default: None 
These are ports that are disallowed to be members of the VLAN. 
Examples: 
None - all ports of the switch are allowed to be members of the VLAN 
2,4-6,8 - all ports except ports 2,4,5,6 and 8 are allowed to be members of the VLAN 
IGMP 
Synopsis: { Off, On } 
Default: Off 
This parameter enables or disables IGMP Snooping on the VLAN.  
MSTI
 
Synopsis: 0 to 16
 
Default: 0
 
This parameter is only valid for Multiple Spanning Tree Protocol (MSTP) and has no effect, if 
MSTP is not used. The parameter specifies the Multiple Spanning Tree Instance (MSTI) that the 
VLAN should be mapped to. 
Note:  If IGMP Snooping is not enabled for the VLAN, both IGMP messages and multicast streams will be 
forwarded directly to all members of the VLAN. If any one member of the VLAN joins a multicast 
group then all members of the VLAN will receive the multicast traffic
