Licenses on page 146.
Figure 74 Working of RMP
By default, the data frames the mesh portal receives on its mesh link are forwarded according to the bridge
table entries on the portal. However, frames received on mesh private VLAN (MPV) are treated differently by
the remote mesh portal. These frames are treated the same as frames received on a split SSID and are routed
rather than bridged. Mesh points obtain DHCP addresses from the corporate network. then register with the
controller using these IP addresses. When these mesh points send and receive PAPI control traffic from the
main office controller, it controls these mesh points just as if they were on a local VLAN. PAPI traffic containing
keys and other secret information receives IPsec encryption and decryption when it is forwarded to the
controller through the VPN tunnel.
Not all traffic from a mesh point is sent on the mesh private VLAN. When a mesh point bridges data received
via its Ethernet interface or from clients connected to an access radio VAP, the mesh point does not tag the
frame with the mesh private VLAN tag when it sends the data through mesh link to the remote mesh portal.
Note that the mesh point may still tag the frame depending on the VLAN of the virtual AP and the native VLAN
specified in the system profile. Care must be taken to assign the MPV value so that it does not clash with any
local tags assigned in the mesh network. In this scenario, the portal performs the default operation and bridges
the frame based on its bridge table. Traffic destined to the Internet is recognized as such by the remote mesh
portal based on ACL rules. This traffic is NATed on the remote mesh portal’s Ethernet interface.

(RMPs) on page 659
Understanding the AP Boot Sequence
The section describes the boot sequence for mesh APs in detail. Depending on its configured role, the AP
performs a slightly different boot sequence.
