All LACP ports in the same trunk group must be either all static LACP or all dynamic LACP. Before removing a port from a trunk, Hewlett Packard Enterprise recommends that you either disable the port or disconnect it from the LAN. counters. The cluster has 2 AHV nodes and the new switch is Aruba 6300. LACP is used for the collective handling of multiple physical ports that can be seen as a single channel for network traffic purposes. ) When the other port becomes active again, the replacement port goes back to blocked (Port Status is "Blocked". Do you have more ports than port 15 on your Trk1? For completeness, a Trunk in ArubaOS Switch is what in some other switches is called a portchannel or etherchannel, it's bundling Currently facing one weird scenario about LAG configure success, but when cable plug out and plug in, all interface in same LACP's forwarding state become LACP-Block, Consider that a Trk1 logical interface made of two physical interfaces 1/51 and 1/52 (your trunk 1/51, 1/52 trk1 lacp definition) is automatically seen by the Spanning Tree topology The port being blocked is the result of LACP failing. Hi, we have 2 These ports (1/A1 & 8/A1) form a trunk group, trk1, running "dt-lacp". LACP requires PDUs, so if you're out of buffers, they'll get dropped just like everything else. When I configure both ports to a dynamic link-aggrgation, the port on the 2930f does not come up. As soon as I installed Switch 2 on site in To enable LACP on a static-trunked port: Use the no trunk <port-number> command to disable the static trunk assignment. Only solution which worked was rebooting of 7250s. I have 4 Aruba 2930F, two in VSF on one side, and the other two in VSF on the other side. 2) How do I configure trunking(as in cisco) to pass multiple vlans . Hi, I faced this issue twice in the past 2 weeks. Hendrik. All the interfaces see each other and the LACP is up and sees the peer. speed) is compared to the existing port properties.
