Topology Example Four 257
Chapter 19
z The priority of the VRRP instance on the local switch should be higher
than that of the master
z The pre-emption on the local switch must be enabled to allow the local
switch to take over as master when it is functional.
z AP and RF Settings
AP Settings
This topology has all the APs bootstrapping to the local switch on the
corresponding floor. This would mean that each of these APs need to know
the Local switch address that they need to bootstrap with (the lmsip).
In addition to this, a good practice is to configure the VLAN ID the clients
associating to the APs would be placed in to ensure uniformity among the
clients associating to the L2 connected APs and L3 connected APs. All RF
settings are configured on the master switch.
Requirements
z The configuration on the APs is the same for APs on the same floor but
the vlan-id and lms-ip differ for APs on the different floors. One
approach is to number the APs such that APs connected to local
switch have the same building and floor ID, but the APs on a different
switch will have a different floor ID, ex. APs connected to Local1 have
location ids 1.101.X, APs connected to Local2 have location ids
1.102.X and so on. The global configuration are then applied to location
1.101.0, 1.102.0 etc. where 0 is a wildcard.
z For each wildcard location (ex 1.101.0), the lmsip needs to be config-
ured to ensure that the APs bootstrap to the right local switch. Since
redundancy is used, this address would not the switch address of the
local but the VRRP instance address, ex. 10.1.101.1.10 for VLAN 101
on local 1
RF Settings
On the RF side three SSIDs are required under location 1.101.0, 1.102.0 etc.
The SSIDs, encryption, VLAN IDs and lms-ip settings as per the topology are
listed below.
