Feature similar to Cisco IP SLA and track

Hi I new in Extreme stuff. Pls advise how can I configure to change default route based on ping check. Something similar to cisco ip lsa and tracking. Flow redirect doesn't meet my requirements , I need to change default route because it is propagated by ospf to others switches. Thanks in advance

You can use the keyword "protection ping"


configure iproute add protection ping
configure iproute add protection ping

if both gateways anwer you have a l3 load balancing.

The "ping" protection on a static route is supported in 16.1, 21.1 or later. You can modify parameters (interval and number of miss) for the ping protection with the following command.

# configure iproute protection ping interval miss

If you have an earlier EXOS you can still use upm:

Below a script, that does similar by disabling an Port to an ISP:

create upm profile pingtest

set var primeport 31
# the port of the primary ISP router
set var target
# the target IP address used to determine the health of connectivity to the
# primary ISP
set var CLI.OUT 0
ping count 1 vr vr-default $target
set var pinglist $TCL(split ${CLI.OUT} "\n")
delete var CLI.OUT
set var pingrespln $TCL(lsearch -glob $pinglist *received*)
set var pingresp $TCL(lindex $pinglist $pingrespln)
set var pingnorcv $TCL(regexp -nocase {0 packets received} $pingresp)
if ($pingnorcv == 1) then
disable port $primeport
create log entry "Failed Uplink "
disable upm profile pingtest

create upm timer pingtest
configure upm timer pingtest profile pingtest
configure upm timer pingtest after 1 every 1

Thank you for responses. I have ExtremeOS, protection ping is available from 16.1.3. By the way it isn't meet requirements completly, I want to ping host which I can define. Andre thank you for the script. What in case that route became available?
