The problem :
SNMP utilty reads MIB ports
information on router(Accelar)(what MAC connected what port).
It gets just ports from specific
VLAN and not gets all ports(in my case I have 2 VLANS,so
I can not get 50% of ports!).
I tried to do "walk" on all rapid-city(Accelar's MIB) and then "find" connection information on
specific MAC -> (I knew that this MAC is connected to Accelar to diffrent VLAN),but i find nothing.
