OK, so now we have:
CISCO-SW2#show etherchannel summary
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
d - default port
Number of channel-groups in use: 2
Number of aggregators: 2
Group Port-channel Protocol Ports
------+-------------+-----------+-------------------------------------------
----
1 Po1(SU) LACP Gi0/20(P) Gi0/22(P)
And this seems fine, for the bundle, successfully.
show vlans still shows:
VLAN Name Status Ports
---- -------------------------------- ---------
-------------------------------
1 default active Gi0/1, Gi0/2, Gi0/4, Gi0/5
Gi0/7, Gi0/9, Gi0/10, Gi0/11
Gi0/12, Gi0/13, Gi0/14,
Gi0/15
Gi0/16, Gi0/17, Gi0/23,
Gi0/24
2 DMZ active
3 VLAN0003 active
So, VLAN 1 will talk. I can be on the Cisco switch, 10.10.0.13 for example,
and ping 10.10.0.13 (root) with no problem, obviously. However, I have other
vlans, 2,3,100......and they are on other IP segments, 172.x.x.x and
192.x.x.x and I cannot ping the root switch and nor can they talk to other
machines on the same segments.
My esx hosts are indeed configured on 10.10.0.x, but they have virtual
switches that have nics on those other segments and they used to talk fine.
Since unknown changes to Cisco, now they do not. I am at the switch console,
and cannot ping those vlans. !!!

In your case, the port channel should be configured between the external
ports and your external switch.
The blade servers should not be part of the port channel. If you have a
blade which is using more than one slot, you can create another Port channel
between the Internal ports and the blade servers. You can't use the same
port-channel between multiple devices.
What you can do is :
++ remove the port-channel from port1 to 16.
++ Use one or 2 port channels between the blade center switches and your
core switches
Po1 (G0/20-22) connected to HP Core1
Po2 (G0/23-24) connected to another Blade Switch (Internal port) or
connected to HP-CORE2 direclty
Depends if you wa

I have (2) Cisco blade switches running in redundant mode and each is
connected to the same HP ROOT switch on the other end. Each blade switch
has an LACP / Etherchannel link of 2 cables going to the HP root. STP
enabled on the Cisco's.
Noticed this on my Cisco-SW1 today:
Group Port-channel Protocol Ports
------+-------------+-----------+-------------------------------------------
----
1 Po1(SU) LACP Gi0/1(I) Gi0/2(I) Gi0/3(I)
Gi0/4(D) Gi0/5(D) Gi0/6(I)
Gi0/7(D) Gi0/8(I) Gi0/20(P)
Gi0/22(P)
This shows that gi 0/20 & 0/22 are in use and bundled in port channel as
they should be. My blade servers (gi 0/1 - 0/8) (some of which are down I
know) show (I) independant? Can anyone advise why?
Also, anyone know why a server like gi 0/1 for example will not talk on
multiple vlans?
I mean, they are set correctly on the HP, as I can ping out fine to those
vlans over there. Here is the Cisco config for those vlans. Cisco talks on
VLAN 1 fine. But Vlans 2 & 3, it doesnt.
