poller.php delets ports

Hey Guys,

the Poller.php in my Environment will automaticly delete every port which is detected some moments before.

For example: Cisco Catalyst 2960-S (Poller)

8)()Adding: Gi1/0/29(10129)()Adding: Gi1/0/30(10130)()Adding: Gi1/0/31(10131)()Adding: Gi1/0/32(10132)()Adding: Gi1/0/33(10133)()Adding: Gi1/0/34(10134)()Adding: Gi1/0/35(10135)()Adding: Gi1/0/36(10136)()Adding: Gi1/0/37(10137)()Adding: Gi1/0/38(10138)()Adding: Gi1/0/39(10139)()Adding: Gi1/0/40(10140)()Adding: Gi1/0/41(10141)()Adding: Gi1/0/42(10142)()Adding: Gi1/0/43(10143)()Adding: Gi1/0/44(10144)()Adding: Gi1/0/45(10145)()Adding: Gi1/0/46(10146)()Adding: Gi1/0/47(10147)()Adding: Gi1/0/48(10148)()Adding: Gi1/0/49(10149)()Adding: Gi1/0/50(10150)()Adding: Te1/0/1(10201)()Adding: Te1/0/2(10202)()Adding: Nu0(12001)()Adding: Fa0(12002)()
