There is physical loop detected on Extremex250e-24t switch,due to this entire network went down at one of our customer site.
Is anybody can help me how to block the port if the loop is detected on the switch?

So that in future if physical loop detected on the switch then port will automatically blocked it.

please let me know the procedure for the same.

Thanks in advanced!!!

Hi,

to complete the testing you need to update EXOS to a version that actually supports disabling ports via ELRP. EXOS version 12.0 does not provide this feature. The first EXOS version to provide this feature was 12.5.3.

The recommended EXOS version for X150 and X250 switches is EXOS 15.3.5.2-patch1-9 (see http://documentation.extremenetworks.com/hw_sw_compatibility/HardwareSoftwareCompatibility/r_exos-re...). You should consider upgrading to that firmware version.

Best regards,
Erik

i am doing simulation in our lab with x150-24t switch version 12.0.2.25.But some of the commands are not supported like "disable-port duration 300" is not taking it after log.

"configure elrp-client disable-ports exclude PORTLIST" and this is also not taking it.

Could you please suggest what should i do to complete this testing?

Hi,

the x250e is supported by EXOS 15.3, but not by newer EXOS versions. In 15.3, ELRP is configured with:
configure elrp-client periodic VLANNAME ports PORTLIST interval 1 log disable-port duration 300 enable elrp-client This configuration can disable every port on which an ELRP PDU is received.
configure elrp-client disable-ports exclude PORTLISTIf you have an older EXOS version, the commands might be a bit different, but in this case you should upgrade to the supported EXOS 15.3 anyway.

Best regards,
Erik
