Configuring a static trunk or static LACP trunk group
IMPORTANT: Configure port trunking before you connect the trunked links between switches.
Otherwise, a broadcast storm could occur. If you need to connect the ports before configuring
them for trunking, you can temporarily disable the ports until the trunk is configured.
Syntax
trunk <port-list><trk1 ... trk144> trunk | lacp
Configures the specified static trunk type.
Example 77 Static trunk group
This example uses ports C4 to C6 to create a non-protocol static trunk group with the group name
Trk2.
(HP_Switch_name#) trunk c4-c6 trk2 trunk
Removing ports from a static trunk group
CAUTION: Removing a port from a trunk can create a loop and cause a broadcast storm. When
you remove a port from a trunk where spanning tree is not in use, HP Switch recommends that you
first disable the port or disconnect the link on that port.
Syntax
no trunk <port-list>
Removes the specified ports from an existing trunk group.
Example
To remove ports C4 and C5 from an existing trunk group:
(HP_Switch_name#) no trunk c4-c5
Port Shutdown with Broadcast Storm
A LAN broadcast storm arises when an excessively high rate of broadcast packets flood the LAN.
Occurrence of LAN broadcast storm disrupts traffic and degrades network performance. To prevent
LAN traffic from being disrupted, the use of fault-finder commands trigger a port disablement when
