Well, the trunk works for VLAN 1, seemingly OK......

 

Thes are Cisco CS3020 blade switches. Ithought they did encapsulation
802dot1q by default ?

 

The HP shows this:

 

ROOT-LAB10# show lacp

                           LACP

   PORT   LACP      TRUNK     PORT      LACP      LACP

   22     Active    Trk1      Down      No        Success

   38     Active    Trk2      Up        Yes       Success


My LACP uplinks are on 21&22 and 37 & 38. I currently have 1 down because
switch is pulled on Cisco side.

What mode of trunking is the HP switch doing?   I believe by default Cisco
does ISL for trunk mode.   If the HP is doing dot1q then you need to define
that on the Cisco side since ISL is default:

 

interface x/y

 switchport trunk encapsulation dot1q

 switchport mode trunk

 

 

 

Hope this helps.

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.

Anyone can help?????

 

VLAN 1 is 10.10.0.x

VLAN 2 is 172.18.32.x

VLAN 3 is 192.168.1.x

 

I can only ping 10.10.0.x n VLAN 1, so traffic moves accros these
LACP/etherchannel fine, but only for that VLAN.
