We are deploying two Bras pppoe licensed to 24,000 sessions each. The problem is that when mass authentication begins to arrive the CPU goes up and it locks up everything and the $
To have an example below, I only have 4,000 sessions to authenticate and the impression it gives is that we have a lot more sessions than this are attempts ...
Today each has 300 sessions and 5% cpu. If you release a Vlan with more than 500 pppoe users, the cpu goes up and does not authenticate everyone and gets the CPU staying at 99%.
What can it be?
PTA : Locally terminated sessions
FWDED: Forwarded sessions
TRANS: All other sessions (in transient state)
