ICX 7150 switch LAG issues - odd error on one switch - same tag type

[david_field_19o]

Hello All,

Hopefully and easy one for someone but being new to Brocade OS its got me stumped.

I have 2 x 7150s and trying to build a LAG.  
Switch 1 I have LAG up and operational ports 1/3/2 and 1/3/4

telnet@BasementStack1#sh lag
Total number of LAGs:          1
Total number of deployed LAGs: 1
Total number of trunks created:1 (127 available)
LACP System Priority / ID:     1 / 78a6.e141.3f96
LACP Long timeout:             90, default: 90
LACP Short timeout:            3, default: 3
=== LAG "1stFlr" ID 1 (dynamic Deployed) ===
LAG Configuration:
   Ports:         e 1/3/2 e 1/3/4
   Port Count:    2
   Lag Interface: lg1
   Trunk Type:    hash-based
   LACP Key:      20001


Switch 2 cant add port 1/3/2 and get error 
Error - port lg1 and port 1/3/2 must have the same tag type


MariansStack2(config-lag-ToBasment)#sh lag

Config Snip

Switch 1
lag 1stFlr dynamic id 1
 ports ethe 1/3/2 ethe 1/3/4


Switch 2
lag ToBasment dynamic id 1
 ports ethe 1/3/4

Iv'e checked vlans etc.. and neither port is in any of the vlans. so Default

Can anyone advise what the error means?  running  SW: Version 08.0.61aT211

Thanks in advance
