Cisco UC500 series Configuration Manual page 7

This template for a LAN topology also supports running the IOS firewall feature
set on the UC500 platform although the firewall configuration is not covered in
this document.
Considerations for this topology include:
• The "WAN" segment between the Managed Access Router and the
UC500 is assumed to be in the 1.1.100.0/24 subnet but can be modified
based on deployment options. The subnet can be modified by the VAR or
end-customer so long as the subnet changes are addressed in the UC500
"WAN" interface and routing configuration.
• Some providers may also provide a publicly routable address for UC500
rather than use a private IP address. This has the benefit of avoiding
"NATing" for IP traffic at the Managed Access Router and can simplify
remote access to the UC500, via VPN or SSH or telnet.
•
"VLAN 1", "Voice VLAN 100", and the subnets depicted can be
modified by the VAR or end-customer to suit customer requirements.
• PCs may or may not be attached through Cisco IP phones according to
customer preference, but the maximum number of ports supported by
UC500 is 48.
• Inline power support for the IP phones is provided by UC500.
• The UC500 provides routing for all devices in VLANs 1 and 100, and also
NATs the 192.168.10.0/24 subnet for the data VLAN 1 to allow access to
the internet.
