Port aggregation between H3C and 3Com Switches?

[Sober]

Is it possible to aggregate ports between a H3C S5500-EI SFP switch and a 3Com 5500G-EI SFP switch?

I have tried linking two aggregate static ports on each switch but with no success.

[CyberNerd]

yes. can you post your config.

Thank you CyberNerd .

I have changed the H3C aggregation to dynamic on ports 1&2 and the 3Com to static on ports 5&6, will try connecting fibre later today when the students and staff have left.

I have attached two configuration files.

I think you need to set them up the same on both sides - mine are as below.

You should change the default snmp write password as well

 

ink-aggregation group 1 mode static

link-aggregation group 1 description switch

 

#

interface GigabitEthernet1/0/1

broadcast-suppression pps 3000

undo jumboframe enable

lacp enable

port link-aggregation group 1

apply qos-profile default

 

interface GigabitEthernet3/0/10

broadcast-suppression pps 3000

undo jumboframe enable

lacp enable

port link-aggregation group 1

apply qos-profile default

The H3C S5500-24F-EI will only allow dynamic with LACP enabled and Static with LACP disabled, that is through CLI or GUI?

 

I have tried H3C dynamic and 3com Static with LACP enabled also H3C Static and 3Com Manual with LACP disabled, the 3Com is OK with both set-ups and aggregate ports connecting but the H3C is anything but OK. H3C system log below:

I have checked the port settings on both switches i.e. duplex etc. are set the same, I will have another go tomorrow but I cannot re-set the H3C and start from scratch untill the college breaks up for Xmas.

 

Thanks again for your help.

my mistake - Set one side as static and the other as dynamic with lacp

[Sober]

Success, H3C dynamic and 3com Static with LACP enabled, I changed aggregated ports from 1&2 on H3C to 3&4. Ports 1&2 had been set up with IRF?
