3Com 8800 Link Aggregation (LACP)

[daz306td]

Hello all,

I wondering if anyone has any experience with configuring Link Aggregation (LACP) on a 3Com 8800? As I understand Link Aggregation there are two modes - active and passive. If I have configured the LACP group between two ports how can I tell what mode the group is configured with?

Many Thanks in advance.

You can try:
display link-agg summ
display link-agg verbose
This one will display Aggregation Type and Loadsharing Type

display link-agg interface g1/0/1

not sure if this helps or not but here is a basic config example:

Manual Link Aggregation

Switch A:
[switcha]link-aggregation group 1 mode manual
[switcha]int gigabit1/0/1
[switcha-GigabitEth1/0/1]speed 1000
[switcha-GigabitEth1/0/1]duplex full
[switcha-GigabitEth1/0/1]port link-aggregation group 1
[switcha-GigabitEth1/0/1]int gigabiteth1/0/2
[switcha-GigabitEth1/0/2]speed 1000
[switcha-GigabitEth1/0/2]duplex full
[switcha-GigabitEth1/0/2]port link-aggregation group 1

Switch B:
[switchb]link-aggregation group 1 mode manual
[switchb]int gigabit1/0/1
[switchb-GigabitEth1/0/1]speed 1000
[switchb-GigabitEth1/0/1]duplex full
[switchb-GigabitEth1/0/1]port link-aggregation group 1
[switchb-GigabitEth1/0/1]int gigabiteth1/0/2
[switchb-GigabitEth1/0/2]speed 1000
[switchb-GigabitEth1/0/2]duplex full
[switchb-GigabitEth1/0/2]port link-aggregation group 1

LACP is the "DHCP" way of setting it up.
To do this, enable LACP on each of the aggregate link ports. thats it.
