These two settings are often confused:
set span ?
...
portadmin Set portadmin to enable or disable the Spanning Tree
algorithm on one or more ports
portenable Set the port status on a port
...
portadmin stops processing (both RX and TX) of STP BPDUs on the selected port.
Effectively this separates two STP "domains".
portenable will stop bridging on the specified port. You don't want this.

Subject: [enterasys] two questions concerning vrrp and stp
Hello,
I have two questions concerning the configuration of vrrp and stp:
1. Is it recommended to disable ip redirects on l3 interfaces when
using VRRP?
I know that recommendation from cisco (with hsrp) to prevent ip
redirects to physical interface ip addresses which cancels the
redundancy function. Does anybody know if "no ip redirects" is
recommended respectively working well also when using DFEs with VRRP?
2. How to deactivate STP BPDUs (in and out) on a switchport?
Is the command "set spantree portenable <Port> disable" the best way to
isolate two single connected stp domains from each other when l3 is not
possible?
Best Regards and many thanks in advance,
