It is difficult to catch it, I have seen 36.6 on bcmRX process, that is
the only thing that goes high.
This is I suppose related to IRQ load on CPU0 ~20%
There is almost no IP configuration on that switch except of management
on vlan Default.
The only features used are:
- elsm on 12 ports
- eaps - 3 rings
- vlan statistics - 2 vlans are monitored on one of the ports in slot-2
- 644 vlans
I have noticed a problem with Cacti.
look:
+ Running data query [1].
+ Found type = '3' [SNMP Query].
+ Found data query XML file at
'/usr/local/share/cacti/resource/snmp_queries/interface.xml'
+ XML file parsed ok.
+ Executing SNMP get for num of indexes @ '.1.3.6.1.2.1.2.1.0' Index
Count: 705
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1' Index
Count: 0
+ No SNMP data returned
However when I use classical snmpwalk it works fine !
Cacti works great with x450 with 12.4 - have no idea if there is any
relation here, but it is strage.
Besides - switch seems to work fine ;)

Yeap, no support purchased ;)
