Configuring the Local Area Network Switch

---

This chapter provides a brief overview of the local area network (LAN) switches (Cisco Catalyst Switch family) in your solution. The LAN switch connects the Cisco MGC hosts to the media gateways (MGWs) or to the Cisco Signaling Link Terminals (SLTs). A LAN switch is not provided with the Cisco MGC.

LAN Switch Overview

The LAN switch is used in the Cisco MGC node to extend virtual LANs (VLANs) across platforms through backbone Ethernet connections, when necessary.

Figure 5-1 illustrates an example of a fault-tolerant control signaling network using dual Cisco Catalyst LAN switches.

Note Make sure that the duplex on the Cisco catalyst port is correctly configured and that there is no duplex mismatch between the switch and the shelf controller (SC) network interface card (NIC). Otherwise, some SS7 messages, although received at the SC NIC, might be ignored by the SC call processing engine.
