Cisco Wireless LAN Controller (WLC) are classified as Routers instead of Switches (WAPs also don't get discovered) - Known Error

Cisco Wireless LAN Controller (WLC) are classified as Routers instead of Switches (WAPs also don't get discovered) Description Cisco Catalyst 9800 Wireless LAN Controllers (WLC) are classified as Routers [cmdb_ci_ip_router] instead of Switches [cmdb_ci_ip_switch]. This means:

The CI is inserted in the Router table, with incomplete data The Network Switch Pattern's WAPs extension doesn't run, so cmdb_ci_wap_network CIs don't get created There is no out-of-box OID record for the following, so it is up to the SNMP - Classify sensor to realise that the device is to be treated as a Switch, but thinks it is a Router instead.

Discover a Cisco Catalyst 9800 Wireless LAN Controller. e.g. a WLC Cisco C9800-L-F-K9 Actual behaviour: The CI will be put in the Router table, and the WAP CIs are not created. Or an existing Switch CI will be reclassified as Router.

Expected behaviour: Cisco WLC devices should always be classified as Switch

Workaround This problem is currently under review and targeted to be fixed in a future release. Subscribe to this Known Error article to receive notifications when more information will be available.

To workaround the Classifier sensor issue, you can adding the 4 OIDs to the instance. Update set sys_remote_update_set_a5bfbc711be1b590cc0feb13604bcb88.xml contains the 4 OIDs listed above.
