Port aggregation between H3C and 3Com Switches?

[JCCC]

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.

Shouldnt be a problem. Can you post the relevant configurations?

[JCCC]

Attached the two config files.

The 3Com 5500G_SFP_EI connect ok but the H3C complains and then loses connection, I then plug a link fibre back into a non aggregate port  to reconnect?

The H3C S5500_24F_EI Aggregate ports are not configured properly?

[Fredrik Lönnman]

The H3C is configured with LACP dynamic and the 3Com is static. Change the 3com to dynamic, should work.

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?

[Fredrik Lönnman]

Uhm, weird. I see no IRF in your configs? Also, on the 5500EI I'm pretty sure IRF is only available on the 10G ports.
