'''Nortel Simple Loop Prevention Protocol (SLPP)''' in [[computer networking]] is a [[Data link layer|layer 2]] protocol inventeted by [[Nortel]] to protect against network loops. SLPP uses a small hello packet to detect a network loops. The SLPP protocol checks packets from the originating switch and the peer switch in a [[SMLT]] configuration. Sending hello packets on a per VLAN basis allows SLPP to detect VLAN based network loops for un-tagged as well as tagged IEEE 802.1Q VLAN link configurations. Once a loop is detected, the port is shutdown.
