ELRP Egress Port Disable

When a loop is detected via ELRP, an option to disable the port where the packet egressed was added to suppress the loop in ExtremeXOS 16.1. All existing functionalities supported on disabling the port where the packet ingressed are supported on this enhancement as well. A log message or SNMP (Simple Network Management Protocol) trap will be generated based on the configuration. The user must specify a holdtime or keep the port disabled until a user enables it.

ELRP egress blocking enhancement adds the following value:

More efficient bandwidth utilization.
Better loop protection in MLAG (Multi-switch Link Aggregation Group) environment. If an edge device is dual-homed to an MLAG pair and this edge device loses its LAG (Link Aggregation Group) configuration, ELRP will be able to prevent the loop by disabling egress port.
