Two stacked M6348 with 4 port broadcom nics - Unable to create more than 18 port channels for LACP teams
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.
Maximum allowable dynamic Port-channels already present in the system.
console#show interfaces port-channel

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)

Yea, I ended up finding that yesterday. Strange limitation, I wonder why? Anyway not a huge deal to do generic trunking. I was just not associating the dynamic with lacp and generic trunking with static.
Thanks!
