Chapter 17 Link Aggregation When you enable LACP link aggregation on a port, the port can automatically negotiate with the ports at the remote end of a link to establish trunk groups. LACP also allows port redundancy, that is, if an operational port fails, then one of the "standby" ports become operational without user intervention. Please note that: • You must connect all ports point-to-point to the same Ethernet switch and configure the ports for LACP trunking. • LACP only works on full-duplex links. • All ports in the same trunk group must have the same media type, speed, duplex mode and flow control settings. Configure trunk groups or LACP before you connect the Ethernet switch to avoid causing network topology loops. 17.2.1 Link Aggregation ID LACP aggregation ID consists of the following information1: Table 39 Link Aggregation ID: Local Switch SYSTEM PRIORITY MAC ADDRESS KEY 0000 00-00-00-00-00-00 0000 PORT PRIORITY 00 Table 40 Link Aggregation ID: Peer Switch SYSTEM PRIORITY MAC ADDRESS KEY 0000 00-00-00-00-00-00 0000 PORT PRIORITY 00 PORT NUMBER 0000 PORT NUMBER 0000 180 1. Port Priority and Port Number are 0 as it is the aggregator ID for the trunk group, not the individual port. XGS4700-48F User's Guide
