Pour que l'EtherChannel fonctionne avec LACP, il faut être active/active ou active/passive. mode 1 (active-backup) Active-backup policy. 4. Unlike manual LAG, LACP can detect not only link disconnections but also more subtle issues such as link layer errors or connection mismatches. Passive —LACP mode that places a port into a passive negotiating state in which the port responds to LACP packets that it receives but does not initiate LACP negotiation. The fallback timer specifies the period the LAG waits to receive a peer PDU. switch(config-lag-if)# no lacp mode active. The interfaces with the highest LACP interface priority become active interfaces. Dynamic LAG or LACP: The local device and the peer device automatically maintain the aggregation states of the member ports, resulting in link failure being quickly detected by exchanging the PDU. Virtual Local Area Network (VLAN) passing on both sides should match. LACP is an open protocol, published under the 802. xxx-fg1 (AggPath) # set lacp-mode ? static Use static aggregation, do not send and ignore any LACP messages.
