Chapter 30: IGMP Snooping Commands

Note the following before using this command:

❑You must first create the protected ports VLAN by giving it a name and a VID before you can add ports. Creating a VLAN is accomplished with CREATE VLAN PORTPROTECTED on page 466.

❑Both command syntaxes perform the same function. The difference is that with syntax 1 you can add ports of only one type, tagged or untagged, at a time. With syntax 2, you can add both at the same time.

❑If you are adding an untagged port to a group, the port cannot be an untagged member of another protected port VLAN. It must be an untagged member of the Default_VLAN or a port-based or tagged VLAN. To remove a port from a protected port VLAN, use DELETE VLAN on page 467.

❑You cannot add a new uplink port to a VLAN if the VLAN has already been assigned an uplink port. Instead, you must delete the existing uplink port(s) using the DELETE VLAN on page 467 and then re-add the uplink port(s) using this command.

❑You cannot add ports to an existing group. To modify an existing group, you must delete the group by removing all ports from it, using DELETE VLAN on page 467, and then add the ports back to the group using this command.

Examples

The following command uses syntax 1 to specify that port 11 is to be an untagged uplink port for the protected ports VLAN called InternetGroups:

add vlan=InternetGroups ports=11 frame=untagged group=uplink

The following command accomplishes the same thing using syntax 2:

add vlan=InternetGroups untaggedports=11 group=uplink

The following command uses syntax 1 to create group 4 in the InternetGroups VLAN. The group will consist of two untagged ports, 5 and 6:

add vlan=InternetGroups port=5,6 frame=untagged group=4
