Hi, Here is description of M6348: Link Aggregation with support for up to 48 LAGs total, up to 18 of which can be dynamic, aggregated links, 8 dynamic aggregated links per switch and up to 8 member ports per aggregated link; LACP support (IEEE 802.3ad), LLDP-MED You can have max 18 LACP port-channels, other must be static (channel-group port-channel-number mode on)
  I am trying to create a Hyper-V HA cluster with 10 blades in an m1000 with two m6348 switches on fabric B. I am trying to create two 802.3ad LACP teams on each blade to handle the VLANs required. When I try to configure ports 1/g19, 2/g19 I get the error message below. Am i doing something wrong? Surely I can create LACP teams on more then 9 blades? Any help appreciated.   interface ethernet 2/g19 switchport mode general switchport general acceptable-frame-type tagged-only switchport general allowed vlan add 20,30 tagged exit console(config)#interface eth 2/g19 console(config-if-2/g19)#channel-group 19 mode auto Unable to convert static Port-channel to Dynamic.
