Hi @PrabhuK
What do you mean by special characters? These characters all look like valid ASCII characters to me.
Can you please explain what you mean by "radius role name"?
In what context is the Checkpoint log relevant to ISE? Are you using ISE as the RADIUS server for Checkpoint Device Administration?
In ISE we don't talk about roles. Perhaps this is Checkpoint terminology that relates to the RADIUS attributes that are handed back during Authorization to allow admins to get the correct RBAC? You need to check your ISE Authorization Policies and Profiles to see what ISE is returning to the Checkpoint.
