ELRP + UPM = Number of UPM Events in Queue for execution

[AlexanderT]

Hello!

I want to execute UPM after every LOOP detect without Queue.

Now, I see couple of loops , but UPM executes with Queue.

Hello Pavel, you dont solve the loop, you temporary remove the vlan and add it back after which the loop starts again.I suggest you disable with UPM the port reported by ELRP so the loop will not return.

Why do you think 'the loop don't solved' after 1 minute, for the time that vlan was removed from port ? It can be very temporarily loop created by some rebooting device for example.

If only one packet received by ELRP why need I shut the port and wait for admin to recover? (Again, it is not edge port, it is some peering, interconnect, and so on. Here are couples or tens vlans, and if one of its loop, the others must work )

It's way better the box to recover automatically by itself , and if loop detected again than block/remove vlan again.

Here is how it works on D-Link switches , flawlessly I think :

Ок, then UPM is not what I need.

But what tools I need to run commands in parallel or so ?

Here is what I want to do every time when LOOP detected :

configure vlan $EVENT.LOG_PARAM_1 delete ports $EVENT.LOG_PARAM_7
set var temp $TCL(after [expr 60*1000])
configure vlan $EVENT.LOG_PARAM_1 add ports $EVENT.LOG_PARAM_7 tagged

Hello Pavel, what do you mean you want to execute UPM without queueu ? A UPM profile is always run by adding it to the current UPM scheduler and run as soon as possible.
