Prerequisites; Default Link Aggregation Configuration - Nokia ESB26 User Manual

7.

Prerequisites

The following guidelines apply to LAG configuration:
• You do not need to do any changes to existing higher-layer protocols or
applications in order to use Link Aggregation.
• Links that cannot take part in Link Aggregation - due to their inherent
capabilities or the capabilities of the devices to which they attach, or due to
management configuration -operate as normal, individual links.
• LACP supports only point-to-point full-duplex links. Aggregations among more
than two devices (multipoint aggregations) and half-duplex operation are not
supported.
• All links in a Link Aggregation Group operate at the same data rate (e.g., 10
Mbps, 100 Mbps, or 1000 Mbps).
• The ports that participate in a LAG must all be of the same bandwidth. 10/100
BaseTx copper ports must belong to the same slot or device, but need not be
contiguous (e.g. – you may include ports 1/1/3 and 1/1/5 in a LAG without
including port 1/1/2).
• When the switch is connected to a LAN and Spanning Tree protocol is not
active, physically connect the aggregated ports ONLY after LAG configuration
is completed.
