Comware

Hello All,

 

I am trying to craete  link aggregation on HP A5500-HI switch and so far I have used the following commands:

 

Dynamic link aggregation
system-view
interface bridge-aggregation 1
link-aggregation mode dynamic
quit

interface GigabitEthernet 1/0/23
port link-aggregation group 1
quit

interface GigabitEthernet 1/0/24
port link-aggregation group 1
quit

interface bridge-aggregation 1
port link-type trunk
port trunk permit vlan 10
quit

Check your link aggregation
display link-aggregation summary
display link-aggregation verbose Bridge-Aggregation 1

 

All those commands work without any issue however when I do display link-aggregation summary I can only see ONE PORT selected and other for UNSELECTED.

 

So when I looked at the logs I found the following error: Member port GigabitEthernet1/0/24 of aggregation group BAGG1 becomes INACTIVE because the port's speed is improper for being attached.

 

Does anyone here know what does this mean?

 

 

Thanks in advance

What do you have connected at the other end?  What version of Comware do you have installed in the switch?

What is the output if you do the following?

interface bridge-aggregation 1
display this

interface GigabitEthernet 1/0/23
display this

interface GigabitEthernet 1/0/24
display this

Also using "link-aggregation mode dynamic" means that you activate LACP (if im not mistaken).

If you want to setup a link aggregation towards another HP A-series switch using LACP isnt really needed.

I am connecting to a physical server it is a HP server DL360 (I think). Also how do I enable LACP?

Furthermore I just noticed this port 23 have speed of Auto [10M] where port 24 Auto [1000M]. Now I am thinking it could be cable as I have forced the NIC on the server to be 1000M Full Duplex. Any Idea?

Thanks

I think that IEEE states that for 1Gbit or higher you should use auto/auto (speed=auto, duplex=auto).

 

So make sure that both ports are set to the same speed and set the server to use auto/auto in order to get a proper link at 1Gbit/s.

 

This should do it for you:

 

int range gi 1/0/23 to gi 1/0/24

speed auto

duplex auto

quit

Yes, you have to enable LACP on the Server as well. Else the Server und Switch will not communicate.

I am not sure why it is only selection one port and not both: btw I have ran following commands:

int range gi 1/0/23 to gi 1/0/24

speed auto

duplex auto

quit

And Finally the following interface summery :

[sw1-GigabitEthernet1/0/23]display this
#

port link-mode bridge
port link-type trunk
port trunk permit vlan 1 10

return
