Etherchannel problem on 4500 switch

[m_tarawneh]

hi,

i have a 4500 switch that has two etherchannel groups each group with 5 gig interfaces, each group is connected to a brocade blade switch, only 2 interfaces are up at a time while the other interfaces has the status (is up, line protocol is down (suspended)), LACP is the protocol used and the interfaces are configured as trunk, any idea how to have all interfaces up?

Try below commands , on Cisco make the mode on and switch portnegotiate

interface GigabitEthernet0/47
switchport mode trunk
switchport nonegotiate
channel-group 5 mode on
!
interface GigabitEthernet0/48
switchport mode trunk
switchport nonegotiate
channel-group 5 mode on

interface Port-channel5
switchport mode trunk
switchport nonegotiate

on foundry , use the command to group the ports together( port e 10 ,e 11 are the ports in brocade).Also tag this ports with all vlans

trunk ethe 10 to 11
