Hi,
Currently trying to configure two HP C7000 Chassis ports bundled into one EtherChannel, trunking multiple VLANs on a Cat9300
When we configure the interfaces with channel-group 10 mode on, both links come up bundled into the port channel but the hosts on the VM side are inaccessible.
When we configure the interfaces with channel-group 10 mode active, one interfaces goes suspended and one stays up and bundled.
The HP config is very basic and only used VLAN tagging and the LACP seems to be set and the timer set to short.
Group: 10
----------
Group state = L2
Ports: 2 Maxports = 16
Port-channels: 1 Max Port-channels = 16

Channel group = 10 Mode = Active Gcchange = -
Port-channel = Po10 GC = - Pseudo port-channel = Po10
Port index = 0 Load = 0x00 Protocol = LACP
Flags: S - Device is sending Slow LACPDUs F - Device is sending fast LACPDUs.
A - Device is in active mode. P - Device is in passive mode.

Don't have a switch in the HP side. They just use Shared Uplink Sets.

anyway now you know why the bundle not form, the HP use different Dev-ID and Dev-ID need by Cisco to know that this port is for this port-channel and that port is for other port-channel.
and why it accept with Mode ON because Mode ON no read this detail it put port to port-channel and later you will face issue like yours "no connectivity".
