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?

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.

[/TD] [/TR] [/TABLE] 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. Sober.

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. Sober a5500.txt E5500G_1.txt

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.
