Redundancy Cluster Prerequisites
Before you start configuring redundancy clusters, make sure you have the following:
 Two ShoreTel Mobility Router 4000 Series appliances
 Each Mobility Router has a unique IP address and hostname.
 Both Mobility Routers are running the same image of ShoreTel Mobility system software
(Version 2.0 or later).
 Both Mobility Routers are in the same subnet.
 Virtual IP address, which is a separate IP address that the two Mobility Routers share and is the
management IP address for the two Mobility Routers
 (Secure Remote Voice and secure enterprise services only) Secure Remote Voice virtual IP
address, which is a separate IP address that the two Mobility Routers share. This IP address is the
IP address that mobile devices access if the address is publicly accessible. It can also be an
internal IP address if you are using NAT on a firewall.
 Verify that the switch ports that are connected to the Mobility Routers meet one of the following
requirements:
 If Spanning Tree Protocol (STP) is enabled on the switch ports that are connected to the
Mobility Routers, portfast must also be enabled.
 STP is disabled on the switch ports that are connected to the Mobility Routers.
Redundancy Cluster Scenarios
How you configure a redundancy cluster depends on the scenario. The following are the scenarios in
which a redundancy cluster can be formed:
 Two new or factory-default Mobility Routers that are to be configured as a redundancy cluster.
(See “Creating a Cluster with Two New Mobility Routers” on page 230.)
 A Mobility Router has already been configured with users who are provisioned, and you want to
add a new Mobility Router to form a cluster. (See “Creating a Redundancy Cluster with a
Configured Mobility Router and a New Mobility Router” on page 233.)
 A Mobility Router that has already been configured with provisioned users and is configured for
remote access (Secure Remote Voice or secure enterprise services).
