I'm using CisocWorks 2000 with Common services 2.2 with IDU 3.5. When I try to check the connectivity between LMS & my core switch (6500-E) through SNMP, it gets failed. But I'm getting syslog messages & also able to see the inventory of this switch. Besides this all other devices are accessible including 7609 routers. The Supervisor Engine version is same on both 6500 & 7600.
There is a firewall between the server & switch. I've opened the snmp ports on the firewall also.
