Step 2: When a Cisco Catalyst 4507R+E is configured with two Supervisor Engine 7L-E, 7-E, or 8-E modules,
configure the switch to use Stateful Switchover (SSO) when moving the primary supervisor functionality between
modules. SSO synchronizes active process information as well as configuration information between supervisor
modules, which enables a fast transparent data plane failover.

To enable SSO mode you must have a license level of ipbase or entservices operating
on the switch supervisors. You can check the current license level of operation with a
show version command.
Tech Tip
Procedure 2 Configure LAN switch universal settings
Within this design, there are features and services that are common across all LAN switches, regardless of the
type of platform or role in the network. These are system settings that simplify and secure the management of
the solution.
This procedure provides examples for some of those settings. The actual settings and values will depend on your
current network configuration.

Setting Value
Domain Name cisco.local
Active Directory, DNS, DHCP Server 10.4.48.10
Authentication Control System 10.4.48.15
Network Time Protocol Server 10.4.48.17
Step 1: Configure the device hostname to make it easy to identify the device.

Step 2: If the switch VTP mode has been changed from default, configure VTP transparent mode. This design
uses VTP transparent mode because the benefits of dynamic propagation of VLAN information across the
network are not worth the potential for unexpected behavior resulting from operational error.
VLAN Trunking Protocol (VTP) allows network managers to configure a VLAN in one location of the network and
have that configuration dynamically propagate out to other network devices. However, in most cases, VLANs are
defined once during switch setup with few, if any, additional modifications.

Step 3: Enable Rapid Per-VLAN Spanning-Tree (PVST+). Rapid PVST+ provides an instance of RSTP (802.1w) per
VLAN. Rapid PVST+ greatly improves the detection of indirect failures or linkup restoration events over classic
spanning tree (802.1D).
