Use SLPP Guard with SMLT to provide additional loop protection to protect wiring closets from erroneous connections.
SLPP Guard requires Simple Loop Prevention Protocol (SLPP) to be configured in the core of the network. SLPP detects loops in the SMLT network. Because SMLT networks disable Spanning Tree (STP), Rapid Spanning Tree (RSTP), or Multiple Spanning Tree Protocol (MSTP) for participating ports, SLPP Guard provides additional network loop protection, extending the loop detection to individual edge access ports.
SLPP Guard can be configured on MLT or LAG ports. If the edge switch with SLPP Guard enabled receives an SLPP-PDU packet on a port, SLPP Guard operationally disables the port for the configured timeout interval and appropriate log messages and SNMP traps are generated. If the disabled port does not receive any SLPP-PDU packets after the configured timeout interval expires, the port automatically reenables and generates a local log message, a syslog message, and SNMP traps, if configured.
