Campbell has been a hate figure for Spurs fans since he left in 2001
Portsmouth intend to make an official complaint to the Football Association over insults aimed at Sol Campbell by Spurs fans at Fratton Park last Sunday.
Campbell, who chose to leave Tottenham on a free transfer to rivals Arsenal in 2001, was subjected to prolonged abuse.
Complaints from Portsmouth fans were made to Hampshire Police, who initially said they could not take action due to the huge number of Spurs fans involved.
The FA said it will ban for life any fans it can prove were connected.
FA director of communications Adrian Bevington told BBC Radio 5 Live: "This is disgusting, vile abuse - whether it is homophobic or racist, any abuse of that nature is simply not acceptable. We have to have a zero tolerance approach to it.
"The FA, the clubs and the police are working together to identify the individuals.
"There were hundreds of people shouting that abuse at Fratton Park last week and it is very difficult to walk in and try to eject people in that situation.
"What we have to do now is make sure those individuals are identified using CCTV or any other means.
"They need to be identified, publicly arrested - so there is an example made - and banned for life from attending football matches."
