Standalone ELRP gives you the ability to send ELRP packets, either periodically or on an ad hoc “one-shot” basis on a specified subset of VLAN (Virtual LAN) ports. If any of these transmitted packets is received back then standalone ELRP can perform a configured action such as sending a log message to the system log file, sending a trap to the SNMP (Simple Network Management Protocol) manager, and disabling the port where the looped packet arrived.
ELRP uses QP8 to send/receive control packets over the network to detect loops, so it is advisable to not use QP8 in for user traffic in the network.
Configure ELRP packet transmission on specified VLANs.
Specify some or all the ports of the VLAN for packet transmission. Each VLAN must be configured individually for ELRP.
Note
Reception of packets is not limited to any specific ports of the VLAN and cannot be configured.
Save and restore standalone ELRP configuration across reboots.
Request non-periodic or periodic transmission of ELRP packets on specified ports of a VLAN.
