igmp filtering

=

profile <name>

=

Specifies a name (up to 32 alphanumeric characters) for this IGMP

profile name followed by start-addressand end-address

 

 

parameters.

start-address

=

Specifies the starting multicast IP address for a range of multicast IP

 

 

addresses that you want to belong to the IGMP filter profile. IP

 

 

address in the range 224.0.0.0 to 239.255.255.255 are used for IP

 

 

multicasting.

end-address

=

Specifies the ending multicast IP address for a range of multicast IP

An example is shown next.

47.4 Enabling STP

Use the spanning-treeor the mrstp commands to enable and configure STP on the Switch. The difference between the commands is that spanning-treeonly allows you to set up one spanning tree configuration and the mrstp command allows you to set up multiple ones.

Syntax:

spanning-tree

spanning-tree priority <0-61440>

spanning-tree hello-time <1-10> maximum-age <6-40> forward-delay <4-30> spanning-tree <port-list> path-cost <1-65535>

spanning-tree <port-list> priority <0-255> and

mrstp <treeIndex> <cr>

mrstp <treeIndex> priority <0-61440>

mrstp <treeIndex> hello-time <1-10> maximum-age <6-40> forward-delay -> <4-30>

mrstp interface <port-list> <cr>

mrstp interface <port-list> path-cost <1-65535> mrstp interface <port-list> priority <0-255> mrstp interface <port-list> treeIndex <1-4>
