Question
Does EXOS switches have equivalent function for “Uplink Failure Detection” of Juniper – JunOS?
Environment
  • EXOS all
Answer
Uplink Failure Detection is a useful function for a switch to have if it should monitor the uplink port and propagate it’s state to other access port. It is especially used when servers are using network adapter teaming. While EXOS switches don’t have same native function, you can make a simple UPM script and use it as an alternative.
Below is an example of UPM script.
 
1. Monitor Link Down
create upm profile MnLinkDn
if ($EVENT.LOG_PARAM_0 == "%uplink%") then
disable ports %downlink%
endif
.
enable upm profile MnLinkDn
create log filter MnLinkDn
configure log filter MnLinkDn add events vlan.msgs.portLinkStateDown
create log target upm MnLinkDn
enable log target upm MnLinkDn
configure log target upm MnLinkDn filter MnLinkDn
 
2. Monitor Link Up
create upm profile MnLinkUp
if ($EVENT.LOG_PARAM_0 == "%uplink%") then
enable ports %downlink%
endif
.
 
enable upm profile MnLinkUp
create log filter MnLinkUp
configure log filter MnLinkUp add events vlan.msgs.portLinkStateUp
create log target upm MnLinkUp
enable log target upm MnLinkUp
configure log target upm MnLinkUp filter MnLinkUp
