Problem with etherchannel on a Cisco 2960S

Hello everybody,

 

I need to make a etherchannel because a don't have a lot of ethernet card.

 

This is my configuration and a some "show command" to help you to identify, I hope so, my problem.

 

C2960S#sh etherchannel 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
     d - default port


Number of channel-groups in use: 2
Number of aggregators:             2

Group  Port-channel  Protocol    Ports
------+-------------+-----------+-----------------------------------------------
1       Po1(SU)           LACP       Gi1/0/27(P) Gi1/0/28(P) (This is a etherchannel between my 2960S and my 3750G. This 3750G is VTP server and a 2960S is VTP client and all VLAN are declared)
2       Po2(SU)            -         Gi1/0/22(P) Gi1/0/23(P) Gi1/0/24(P) (This, This is the etherchannel between my ESXI v5 server)

If I do a sh int trunk, this trunk It's ok:

C2960S#sh int trunk

Port         Mode                Encapsulation  Status         Native vlan
Po1           on                  802.1q           trunking       1
Po2           on                  802.1q           trunking       1

Port         Vlans allowed on trunk
Po1           1-4094
Po2           1,4,6,100

Port         Vlans allowed and active in management domain
Po1           1,3-7,10-12,50,99-100,801
Po2           1,4,6,100

Port         Vlans in spanning tree forwarding state and not pruned
Po1           1,3-7,10-12,50,99-100,801
Po2           1,4,6,100

This is my cisco 2960 configuration:
interface Port-channel2
description ESX_VLAN_TRUNK_2
switchport trunk allowed vlan 1,4,6,100
switchport mode trunk
switchport nonegotiate

interface GigabitEthernet1/0/22
switchport trunk allowed vlan 1,4,6,100
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-group 2 mode on
!
interface GigabitEthernet1/0/23
switchport trunk allowed vlan 1,4,6,100
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-group 2 mode on
!
interface GigabitEthernet1/0/24
switchport trunk allowed vlan 1,4,6,100
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-group 2 mode on

 

Other show:

Port-channel: Po2
------------

Age of the Port-channel   = 0d:02h:43m:04s
Logical slot/port   = 5/2            Number of ports = 1
GC                      = 0x00000000       HotStandBy port = null
Port state            = Port-channel Ag-Inuse
Protocol              =    -
Port security        = Disabled

Ports in the Port-channel:

Index   Load   Port      EC state         No of bits
------+------+------+------------------+-----------
   0      00      Gi1/0/21 On                     0

Time since last port bundled:    0d:00h:02m:48s    Gi1/0/21
Time since last port Un-bundled: 0d:00h:02m:51s    Gi1/0/21

 

port-channel load-balance src-dst-ip is configured on my Cisco 2960S-G

 


After the configuration has been placed, it can not ping or access to the console with the administration IP address.
The only way is to shutdown all interfaces except one and then you can access the console. If after I do a no sh in another interface, the communication down immediatly.

 

VMWare,
- Load balancing is set to "Route based on IP hash", "State links", "yes", "yes"
- All adapters are reported as active
- Full duplex & speed to 1000 for each adapter
- The VLANID 6 is said to "Management Network"
- A port group server VLANID100
- Etc. ..

 

I admit not knowing what to do.

 

If everyone can help me, it'll be fine.

 

Thank
