Dual-mode ports question

I need to get the config running on a FES2402-PREM to a FCX648S-HPOE.  I have it figured out with the exception of dual-mode ports.  On the FES2402-prem I run a show vlan - pasted below.  Ports 13 and 14 are listed as dual-mode ports on multiple vlans.  On the FCX648S-HPOE (2nd pasted below) it gives an error when I try to add a dual-mode port to anything but the first vlan I type.  How do I add Dual-mode to multiple tagged ports on the FCX648S-HPOE, like the FES2402-PREM shows?  Thanks in advance.

 

PORT-VLAN 127, Name [None], Priority level0, Spanning tree Off
Untagged Ports: 3 4
Tagged Ports: None
Uplink Ports: None
DualMode Ports: 13 14

PORT-VLAN 1103, Name [None], Priority level0, Spanning tree Off
Untagged Ports: None
Tagged Ports: None
Uplink Ports: None
DualMode Ports: 13 14

PORT-VLAN 1104, [None], Priority level0, Spanning tree Off
Untagged Ports: 1 2
Tagged Ports: None
Uplink Ports: None
DualMode Ports: 13 14

 

FCX648SHPOE Router(config-if-e1000-1/1/14)#dual-mode 3
Port 1/1/14 has already been configured as dual mode on VLAN 2

Re: Dual-mode ports question

Dual mode works as follows

 

Start out with the port untagged in VLAN 1 by removing any VLAN tag or untagged configuration

 

Once all vlan info is gone, tag whatever vlan's you want to the ports one by one. Once you have all the VLAN's you want, then specify the VLAN you want untagged traffic on as your Dual mode VLAN.
