Description

Following error could be seen on ACX/PTX EVO router

eventd: could not bind to address x.x.x.x: Cannot assign requested address

eventd: Trying bind to default address

eventd: bind: Invalid argument

 

 

 

 

Symptoms

The reason is we have configured management-instance, thus syslog will be sourced only from interfaces only within instance mgmt_junos.

But the configured address x.x.x.x is from lo0 is in inet.0 table, this error is reported

 

Solution

There’re several workarounds for this:

  1. To filter out this log

https://supportportal.juniper.net/s/article/QFX10K8-eventdcould-not-bind-to-address-xxxxCant-assign-requested-address-syslog-messages

 

set system syslog file messages match "!(.*eventd.*bind*)"

set system syslog file messages any any

 

  1. Use default-address-selection

remove “set system syslog source-address x.x.x.x”

add "set system default-address-selection"

There is PR1774292 to allow syslog sent out from inet.0 while management-instance configured.

This is going to be fixed in
