[j-nsp] EX3300 mac-address aging counter stuck for several mac addresses

[Octavio Alfageme]

Hello everyone,

I have several EX3300s suffering from a strange problem. They run Junos
12.3 and they are far away from their scalability numbers in terms of
number of mac-addresses (6K at maximum) and thorughput. They are mainly
traversed by pppoe subscribers. From time to time and not for every
subscriber, when I run a 'show ethernet-switching table', I see that 'age'
counter is completely stuck and neither goes to zero when the mac is 'seen'
nor goes on growing in case the mac address is not 'seen'. The only way to
return to a normal situation is manually clearing the mac-address entry.
Have you ever had an issue like this in the EX family?

Thanks in advance

Kind regards

Octavio
