To enable MAC-based forwarding in this situation, you must use a layer 3 device between the NetScaler and server. Check whether the STP status of the Eth-Trunk is blocking. This means it does not send LACPDU. If this is not the case, your LAGG did not form. So bring the Nexus switches to same running version and verify if the problem persists. The interfaces that constitute an Eth-Trunk interface are known as member interfaces, and the link corresponding to a member This example displays an LACP configuration of the physical interfaces. I7. Each router floods the LSP to all neighbors, who then store all LSPs received in a database => Step 4. To create a VSX LAG, use the interface lag multi-chassis command. A switching loop occurs when two switches have more than one direct connection. However on switch 1, this same port 19 shows in a "Forward" state and sure enough the LED is lit solid on that physical switch port. It's like saying you drive a Toyota. To display spanning-tree protocol parameter details in the CLI, enter the following commands: show spanning-tree interface. This can cause loops when connecting to an MS390 unless the bundles are configured on the MS390 first. Switch. In dynamic mode, LAGs are aware of their partners’ port-channel states as LACP packets are exchanged between them. Switch S2 did not use a compatible EtherChannel mode.
