Configuring the Local Area Network Switch
Revised: February 21, 2012, OL-18083-14
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 PGW 2200 Softswitch hosts to the media gateways (MGWs) or to the Cisco IP Transfer Point LinkExtender (ITP-L). A LAN switch is not provided with the Cisco PGW 2200 Softswitch..
LAN Switch Overview
The LAN switch is used in the Cisco PGW 2200 Softswitch node to extend virtual LANs (VLANs) across platforms through backbone Ethernet connections, when necessary.
Figure 6-1 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 Cisco PGW 2200 Softswitch network interface card (NIC). Otherwise, some SS7 messages, although received at the Cisco PGW 2200 Softswitch NIC, might be ignored by the Cisco PGW 2200 Softswitch call processing engine.
