Добрый всем день!
Помогите разобраться с etherchannel-oм!

На catalyst3750 сделал так:

interface Port-channel10
switchport access vlan 100
switchport mode access

interface GigabitEthernet1/0/5
switchport access vlan 100
switchport mode access
channel-group 10 mode active

interface GigabitEthernet1/0/6
switchport access vlan 100
switchport mode access
channel-group 10 mode active

На сервере с Red Hat Linux как тут http://www.subversity.net/networking/cisco-redhat-link-aggre...

Но линк не поднимается...
На свитче:

catalyst#sh ip int br
Port-channel10         unassigned      YES unset  down                  down

потом -
catalyst#sh interfaces port-channel 10 status

Port      Name               Status       Vlan       Duplex  Speed Type
Po21                         notconnect   175          auto   auto
Почему "notconnect"?

catalyst#sh lacp 10 counters
             LACPDUs         Marker      Marker Response    LACPDUs
Port       Sent   Recv     Sent   Recv     Sent   Recv      Pkts Err
---------------------------------------------------------------------

Gi1/0/6     3847   0        0      0        0      0         0

"LACPDUs" только - Sent / Receive -0

catalyst#sh etherchannel sum
Flags:  D - down        P - 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
        u - unsuitable for bundling
        w - waiting to be aggregated
        d - default port

Number of channel-groups in use: 1
Number of aggregators:           1

Group  Port-channel  Protocol    Ports

10     Po10(SD)        LACP      Gi1/0/5(s) Gi1/0/6(s)

Почему интерфейсы Gi1/0/5(s) Gi1/0/6(s) - suspend?
