Trunk group configuration rules, Cfg/port x/cur | HP 445946-001

Ports and trunking

1.Read the configuration rules provided in the “Trunk group configuration rules” section.

2.Determine which switch ports (up to six) are to become trunk members (the specific ports making up the trunk).

3.Ensure that the chosen switch ports are set to enabled, using the following command:

/cfg/port x/cur

4.Trunk member ports must have the same VLAN configuration.

5.Consider how the existing spanning tree will react to the new trunk configuration. See the “Spanning Tree Protocol” chapter for spanning tree group configuration guidelines.

6.Consider how existing VLANs will be affected by the addition of a trunk.

Trunk group configuration rules

The trunking feature operates according to specific configuration rules. When creating trunks, consider the following rules that determine how a trunk group reacts in any network topology:

•All trunks must originate from one device, and lead to one destination device. For example, you cannot combine a link from Server 1 and a link from Server 2 into one trunk group.

•Any physical switch port can belong to only one trunk group.

•Trunking from non-HP devices must comply with Cisco® EtherChannel® technology.

•All trunk member ports must be assigned to the same VLAN configuration before the trunk can be enabled.

•If you change the VLAN settings of any trunk member, you cannot apply the change until you change the VLAN settings of all trunk members.

•When an active port is configured in a trunk, the port becomes a trunk member when you enable the trunk using the /cfg/l2/trunk x/ena command. The spanning tree parameters for the port then change to reflect the new trunk settings.

•All trunk members must be in the same spanning tree group and can belong to only one spanning tree group. However if all ports are tagged, then all trunk ports can belong to multiple spanning tree groups.

•When a trunk is enabled, the trunk spanning tree participation setting takes precedence over that of any trunk member.

•You cannot configure a trunk member as a monitor port in a Port Mirroring configuration.

•A monitor port cannot monitor trunks; however, trunk members can be monitored.
