Dell Force10 E600i FTOS Version 8.4.1.5 Configuration Guide for ExaScale - Page 530

www.dell.com | support.dell.com Important Points to Remember • On ExaScale, LACP is supported on 200 physical ports. Use static LAGs for the remaining ports to avoid unpredictable results. • LACP enables you to add members to a port channel (LAG) as long as it has no static members. Conversely, if the LAG already contains a statically defined member (channel-member command), the port-channel mode command is not permitted. • A static LAG cannot be created if a dynamic LAG using the selected number already exists. • No dual membership in static and dynamic LAGs: • If a physical interface is a part of a static LAG, then the command port-channel-protocol lacp will be rejected on that interface. • If a physical interface is a part of a dynamic LAG, it cannot be added as a member of a static LAG. The command channel-member gigabitethernet x/y will be rejected in the static LAG interface for that physical interface. • A dynamic LAG can be created with any type of configuration. • There is a difference between the shutdown and no interface port-channel: - The shutdown command on LAG "xyz" disables the LAG and retains the user commands. However, the system does not allow the channel number "xyz" to be statically created. - The command no interface port-channel channel-number deletes the specified LAG, including a dynamically created LAG. This command causes all LACP-specific commands on the member interfaces to be removed. The interfaces are restored to a state that is ready to be configured. Note: There will be no configuration on the interface since that condition is required for an interface to be part of a LAG. • Link dampening can be configured on individual members of a LAG. Refer to Link Debounce Timer for more information. • LACP cannot add an interface to a LAG if one of the LAG members is shut down on the remote interface. If a remote LAG member is shut down, Message 1 appears on the local system when you attempt to add a member. In this case, enable all members of the LAG on the remote system, and then add any new members on the local system. • FTOS might not synch connected and static routes learned via LACP to the secondary RPM. Configure redundancy protocol lacp to synch LACP states between RPMs. Message 1 LACP Remote Port Down Error Message % Error: This port property does not match with other LAG member. 530 | Link Aggregation Control Protocol
