On a side note:The securestack family will allow thing slike $-, bu no spaces when configuring port alias's

Port ge.1.47 port-alias-&,$@
If they are not avaialbe at this time the these items would be considered a C4 (or care request).
If this is something you wish for on any of the Extreme switches then I would recommend opening a ticket with the GTAC and requested this feature.
I also believe that you can request a feature request in case management section
follow the sites below
http://www.extremenetworks.com/
http://support.extremenetworks.com/
select my case management then select open a case
The request would be processed with feedback
The more the merrier
Thanks,
