set USER_NAME [substr $attr_value 0 "@"]
log "AAA ID: $attr_value User: $USER_NAME"
persist uie $USER_NAME
if { ($USER_NAME ends_with "a") or ($USER_NAME ends_with "b") }
{
log "Username $USER_NAME ends with a|b"
pool RADIUS_POOL member 10.20.0.201
}
elseif { $USER_NAME ends_with "t"}
{
log "Username $USER_NAME ends with t"
pool RADIUS_POOL member 10.20.0.202
}
else {log "Username $USER_NAME"}
}
default { binary scan $rest_string $ff attr_value rest_string }
}
}
}
}
The problem is, that if we remove the default pool from the VS configuration, the traffic is never sent to the backend server.
