Port channel issue

[mramirez-t]

So I'm trying to connect an HP Blade Chassis to our core switch, a Cisco 4500, WS-C4500X-16.  These are set up as a stack.  The chassis has two NICs that need to connect, so I'm connecting them to te1/1/10 and te2/1/10.  If I connect the two NICs to each port without a port-channel, all VMs on the Chassis are communicable across all VLANs, since these ports are trunks.  If I add them to the port-channel, all communication fails.  Not sure what I'm missing.  This is the config that I have which is working.

XXX-4500INT-01#sh run int te1/1/10
Building configuration...

Current configuration : 158 bytes
!
interface TenGigabitEthernet1/1/10
description Uplink to HP Chassis
switchport mode trunk
switchport nonegotiate
no lldp transmit
no lldp receive
end

XXX-4500INT-01#sh run int te2/1/10
Building configuration...

Current configuration : 158 bytes
!
interface TenGigabitEthernet2/1/10
description Uplink to HP Chassis
switchport mode trunk
switchport nonegotiate
no lldp transmit
no lldp receive
end

XXX-4500INT-01#sh run int po5
Building configuration...

Current configuration : 100 bytes
!
interface Port-channel5
description Uplink to HP Chassis
switchport
switchport mode trunk
end

This is the config that I have when I was using port-channel:

XXX-4500INT-01#sh run int te1/1/10
Building configuration...

Current configuration : 158 bytes
!
interface TenGigabitEthernet1/1/10
description Uplink to HP Chassis
switchport mode trunk
channel-group 5 mode on
end

XXX-4500INT-01#sh run int te2/1/10
Building configuration...

Current configuration : 158 bytes
!
interface TenGigabitEthernet2/1/10
description Uplink to HP Chassis
switchport mode trunk
channel-mode 5 mode on
end

XXX-4500INT-01#sh run int po5
Building configuration...

Current configuration : 100 bytes
!
interface Port-channel5

end

How is the other end configured? Have you tried 

channel-group 5 mode active?

Rather that just 'on'?

[mramirez-t]

If I add channel-group 5 mode active to te1/1/10, the communication works.  As soon as I do the same for te2/1/10, te2/1/10 goes into suspended mode and communication fails.  So, it doesn't like the fact that I'm adding both interfaces to the channel-group.

Without the port channel configured and interfaces up, can you post output of

show int status

from the Cisco end. 

how is the HP end configured?

You could run a debug also on the cisco end before bringing up the etherchannel and then look at the output.

From the cisco switch

debug etherchannel

debug lacp

(if using mode active)

term mon

bring up etherchannel and see any output that might give some idea if the issue.

I left te1/1/10 in the channel after the last post.  After adding te2/1/10, below.  No output for about 5 minutes.

Do you have any other port channels to the HP chassis?

Not that familiar with them tbh. How are the two nics on that end grouped? Nic Teaming or something else? Do you have access to the HP side also to check the configuration?

remember to remove the debugs for now on the Cisco switch.

Hello,

I have an issue with port-channeling also.

I am trying to connect Dell SCv3020 to my core switch Cisco 4500-X. When I am creating port channel all ports from channel are going in suspended mode. In the switch log i see LACP currently not enabled on the remote port.

Also on the storage i have messages:

"Data Center Bridging is supported on this port but no TLVs have been received from the switch. Please make sure that DCB is enabled and configured on the switch."

and

"Link Layer Discovery Protocol is supported on this port but no TLVs have been received from the switch. Please make sure that LLDP is enabled and configured on the switch.

After hundred of tests i discover that this switch is not in compatibility list for this storage.

Any chance to still make a port group?
