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, X870 series switches.

Limitations

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.
