I have set up a new switch, I can connect to it thru a web browser or telnet to it thru the network, but when I try to connect to it thru CNA 5.5 I can connect without a problem but it shows up as an unsupported device and I can't do any configurations to it. I am able to configure other 2950, 2960, and 3560 devices without an issue but this is the first 2960s model I have worked with. Is there an issue between CNA and this model that needs to be addressed? The 2960s is running the latest IOS.
Please refer to the CNA Release Notes at http://www.cisco.com/en/US/docs/net_mgmt/cisco_network_assistant/version5_0/release/notes/OL12210a.html .
Specifically, under "New Features" (for Release 5.5, November 2009) you should see the line "Catalyst 2960 switches (WS-C2960-48PST-S, WS-C2960-24PC-S, WS-C2960-24LC-S, and WS-C2960-48PST-L)". Absence of any reference to the 2960S models implies that they are not supported on the current CNA release.
Cisco management products are pretty tightly integrated with both the device's capabilities and typically rely on a given model's unique SNMP OID to tailor the management product's presentation and manipulation of the target device. New products will almost always lag in their support on the network management platforms.
CNA is typically updated once or twice a year, so 5.5 is about due for an update by that timetable. (Not any inside information about a new release here, just an observation and educated guess.)
Hope this helps. Please rate helpful posts.
