we need to enable 802.1x authentication on ex3300 switches, of which we have a lot. The switches have the recommended version Junos 12.3R12-S15 We use a configuration with supplicant multiple and mac radius. see part of configuration:
vitsol@sw-B6# show protocols dot1x
I had to turn off VSTP for authentication to work , when I used VSTP, the users the switch was continuously sending requests to RADIUS server and the switch didn´t accespt RADIUS answer. When I switch off VSTP the authentication worked properly 3 months and now switch cannot authenticate printers. I get error message:
Nov 30 07:51:26.543756 queried vid:12
Nov 30 07:51:26.543800 CreateSession: MAX mem usage limit for sessions exceeded. Skipping Auth For MAC: -.
It seems that some buffer is full. Does somebody know where is problem?
