Hi,
We have a pair of S4810 and N4032 switches in our lab. So we've configured vlt and mlag with a mesh topology.
Although it seems working, following lacp ungroup/group messages appear on the force10 console. As soon as I disabled/shutdown one of the lacp port then it stops dropping any new message.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-UNGROUPED: PortChannel-011-Ungrouped: Interface Te 0/1 exited port-channel 11.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-GROUPED: PortChannel-011-Grouped: Interface Te 0/1 joined port-channel 11.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-UNGROUPED: PortChannel-011-Ungrouped: Interface Te 0/1 exited port-channel 11.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-GROUPED: PortChannel-011-Grouped: Interface Te 0/1 joined port-channel 11.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-UNGROUPED: PortChannel-011-Ungrouped: Interface Te 0/1 exited port-channel 11.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-GROUPED: PortChannel-011-Grouped: Interface Te 0/1 joined port-channel 11.
4d17h13m: %STKUNIT0-M:CP %LACP-5-PORT-UNGROUPED: PortChannel-011-Ungrouped: Interface Te 0/1 exited port-channel 11.
Any help would be appreciated. Also, partial config on both n4032 and s4810 config can be seen below.
