I am trying to Etherchannel two ports where the NIC's are teamed and the ports will not come up...what am I doing wrong?
I configured the two ports as follows
channel-group 195 mode active
port-channel load-balance src-mac
and I set the teamed NIC as follows
Team Type: 802.3ad Dynamic with Fault Tolerance
Transmit Load Balancing Method: Destination IP Address
The port now shows disabled when I do show int status and when I show config it shows shutdown. I ran the no shut on both ports but nothing changed.
here are the show int outputs and the show etherchannel
interface GigabitEthernet9/35
switchport
switchport access vlan 3
switchport mode access
no ip address
shutdown
spanning-tree portfast
channel-group 195 mode active
interface GigabitEthernet10/35
switchport
switchport access vlan 3
switchport mode access
no ip address
shutdown
spanning-tree portfast
channel-group 195 mode active
6513#show etherchannel 195 sum
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
Number of channel-groups in use: 4
Number of aggregators: 4
Group Port-channel Protocol Ports

Here is a helpful link. I think you might want to no shut your ports before connecting the server and configuring the etherchannel. You have selected channel mode active, but may want to try mode on.

Try to enable the ports. They are shutdown

Burleyman,
Can you post the configuration of "interface port-channel 195" ?

From past experience especially with HP NIC teaming for fault-tolerance I specifically configure the etherchannel to mode on.
Incidentally I have come across issues with etherchannels failing to establish when you have subsequently reconfigured the actual port-channel after configuring it logically on the physical interface. For example add vlans if L2.
In these cases I initiated a 'shut' then a 'no shut' on the port-channel. Verify that PO195 is a switchport, and the appropriate vlan has been specified.
Regards
Allan.
Pls rate this post if you find it helpful.

Etherchannel "mode on" is only valid with HP NIC Teaming modes "Switch-assisted Load Balancing (SLB)" and "Dual Channel".
Any HP NIC Teaming type with "802.3ad" in it's title uses 802.3ad LACP to establish the channel. Therefore, the switch must be configured to also use LACP (mode active or mode passive).
In summary, "etherchannel mode active" is the correct config for "Team Type: 802.3ad Dynamic with Fault Tolerance".
The 80+ page HP Teaming whitepaper below provides all the details.

Based on the provided config, I agree that the problem is related to the interfaces being shut.
