Distributed Tunneling Configuration

The Distributed Tunneling mode, also known as AP-AP tunneling mode, is used to support L3 roaming for wireless clients
without forwarding any data traffic to the wireless switch.
In the AP-AP tunneling mode, when a client first associates with an AP in the wireless system the AP forwards its data using
the VLAN forwarding mode. The AP to which the client initially associates is the Home AP . The AP to which the client roams
is the Association AP .
When a client roams to another AP in a different subnet the Association AP tunnels all traffic from the client to the Home AP
using a CAPWAP L2 tunnel. The Home AP injects the traffic received over the tunnel into the wired network. If a client roams
to another AP in the same subnet then the tunnel is not created, and the new AP becomes the Home AP for the client.

Table 330: SNMP Traps (Cont.)
Description
If you enable this field, the SNMP agent sends a trap for one of the following reasons
associated with a peer switch
• Peer Switch Discovered
• Peer Switch Failed
• Peer Switch Unknown Protocol Discovered
• Configuration command received from peer switch. (The switch need not be Cluster
Controller for generating this trap.)
If you enable this field, the SNMP agent sends a trap when the RF scan detects a new AP,
wireless client, or ad-hoc client.
If you enable this field, the SNMP agent sends a trap when the switch discovers a rogue AP.
The agent also sends a trap every Rogue Detected Trap Interval seconds if any rogue AP
continues to be present in the network.
If you enable this field, the SNMP agent sends a trap for one of the following reasons:
• This switch has become Cluster Controller
• Rogue Client detected
• Rogue Client(s) continue to exist, after every Rogue Detected Trap Interval seconds
• Maximum number of Managed APs in the peer group exceeded
If you enable this field, the SNMP agent sends a trap if the operational status of the Unified
Switch (it need not be Cluster Controller for this trap) changes. It sends a trap if the Channel
Algorithm is complete or the Power Algorithm is complete. It also sends a trap if any of the
following databases or lists has reached the maximum number of entries:
• Managed AP database
• AP Neighbor List
• Client Neighbor List
• AP Authentication Failure List
• RF Scan AP List
• Client Association Database
• Ad Hoc Clients List
• Detected Clients List
