Problem

LACP link between a 3750X and a 3Com 4500G.

Solution:

Cisco 3750X:

interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,2
 switchport mode trunk
!
interface GigabitEthernet1/0/1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,2
 switchport mode trunk
 channel-group 1 mode passive
!
interface GigabitEthernet1/0/2
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,2
 switchport mode trunk
 channel-group 1 mode passive
!

3Com 4500G:

system-view
link-aggregation group 1 mode static
link-aggregation group 1 description Link to Cisco
#
interface GigabitEthernet1/0/1
 port link-type hybrid
 port hybrid vlan 2 tagged
 port hybrid vlan 1 untagged
 broadcast-suppression pps 3000
 undo jumboframe enable
 stp edged-port enable
 lacp enable
 port link-aggregation group 1
#
interface GigabitEthernet1/0/2
 port link-type hybrid
 port hybrid vlan 2 tagged
 port hybrid vlan 1 untagged
 broadcast-suppression pps 3000
 undo jumboframe enable
 stp edged-port enable
 lacp enable
 port link-aggregation group 1

Show the config on the Cisco:

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: 1 Number of aggregators: 1

Group Port-channel Protocol Ports ------+-------------+-----------+----------------------------------------------- 1 Po1(SU) LACP Gi1/0/1(P) Gi1/0/2(P)

The 3Com complains that LACP isn't enabled on the remote partner, but the link comes up:
