Interopmode issue with McDATA switch

I have configured Brocade switch with interopmode 2 to migrate McDATA (McDATA Fabric mode)...

I am getting E-port segmented with zone conflict message on Brocade

15  15   640f00   id N1   Online      FC  E-Port segmented,(zone conflict)


Prior to change of interopmode I have done cfgdisable, cfgclear, cfgsave at brocade, configured IM 2 with safe zone ON.

Brocade FOS : v6.4.3d , McDATA is on Firmware Version: 09.08.01

please suggest...

Re: Interopmode issue with McDATA switch

"cfgmcdtmode" command, can you verify if McDATA Config mode is enable or disable.

Additional, i see in switchshow output, the segmented port is set as N1, keep in mind 8G SFP+ not support 1GB FC.

If you have in McDATA Switch 1Gbits SFP, the you must use is 5100 a 4G SFP
