Hardware-Assisted ELRP

Hardware-assisted ELRP allows ELRP to detect loops faster and to support more ELRP clients.

Supported Platforms

ExtremeSwitching X450-G2, X460-G2, X670-G2, X440-G2, X465, X590, X620, X690, X695, X870, 5320, 5420, 5520 series switches.

For hardware-assisted ELRP:

Only front panel ports can be configured as the loopback port.
Only disabling ingress port is supported after a loop is detected.
MLAG ports are not supported.
Software ELRP and hardware-assisted ELRP cannot operate simultaneously.
Only standalone clients are supported.
Not supported on dynamic VLANs.
Maximum loop detection interval is determined by each platforms hardware capability. For most platforms, an ELRP packet is 70 bytes.
Non-periodic requests are not supported.
Extended Edge Switching is not supported.
