I'm running a Catalyst 6513 switch with Native IOS installed. I have created a EtherChannel bundle for an HP Blade server running with two clustered (teamed) NICs. The configurations are as follows:
interface Port-channel100
no ip address
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2
switchport mode trunk
end
!
interface GigabitEthernet10/35
description XPQASRV13 (Cable No.35)
no ip address
speed 100
duplex full
switchport
switchport trunk allowed vlan 2
switchport mode trunk
channel-protocol lacp
channel-group 100 mode active
end
!
interface GigabitEthernet11/42
description XPQASRV13 (Cable No.90)
no ip address
speed 100
duplex full
switchport
switchport trunk allowed vlan 2
switchport mode trunk
channel-protocol lacp
channel-group 100 mode active
end
!
The problem is that running the interfaces at 1GiG causes the two NICs to insert and de-insert on the network every second but forcing them to 100 Meg makes them perform normally. These are connected using Cat5e cables which are 1GIG certified. What could be the cause for this problem?
