what is the command to enable the cge0 device?

Our cge0 device was disabled as part of troubleshooting a networking issue.  What is the command to enable and disable the device?  I thought it would be server_ifconfig - but if I list all the interfaces the cge devices are not listed.

[nasadmin@EMCCTRL nasadmin]$ server_sysconfig server_2 -virtual -i fsn0
server_2 :
*** FSN fsn0: Link is Up ***
active=trk0 primary=trk0 standby=cge2

[nasadmin@EMCCTRL nasadmin]$ server_sysconfig server_2 -virtual -i trk0
server_2 :
*** Trunk trk0: Link is Up ***
*** Trunk trk0: Statistical Load Balancing is IP ***
