After ports are preprovisioned, Link Aggregation Groups (LAGs), multilink-bundles (IMA), or Bundle Protection Groups (for example IMA BPGrps), can be configured to increase the bandwidth available between two nodes.
All physical links or channels in a LAG/bundle combine to form one logical connection. A LAG/bundle also provides redundancy in case one or more links that participate in the LAG/bundle fail. For command syntax for multilink bundles, see Configuring multilink PPP bundles. To configure channelized port for TDM, see Configuring channelized ports. To configure channelized port for Sonet/SDH high speed channels (ASAP MDAs only), see Configuring SONET/SDH port parameters. For command syntax for LAG, see Configuring LAG parameters.
