instance number is not required. For example, the following command configures the Spanning Tree mode
on port 1/24 for the flat mode instance:
-> spantree cist port 1/24 mode blocking
Mode for Link Aggregate Ports
Physical ports that belong to a link aggregate do not participate in the Spanning Tree Algorithm. Instead,
the algorithm is applied to the aggregate logical link (virtual port) that represents a collection of physical
ports.
To change the port mode for a link aggregate, use the spantree vlan mode or the spantree cist mode
command described above, but specify a link aggregate control (ID) number instead of a slot and port. For
example, the following command sets the port mode for link aggregate 10 associated with VLAN 755 to
blocking:
-> spantree vlan 755 linkagg 10 mode blocking
For more information about configuring an aggregate of ports, see Chapter 8, “Configuring Static Link
Aggregation,” and Chapter 9, “Configuring Dynamic Link Aggregation.”
