Chapter 7 WAN Setup VC-based Multiplexing In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical. LLC-based Multiplexing In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs. 7.6.3 VPI and VCI Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for more information. 7.6.4 IP Address Assignment A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and ENET ENCAP gateway. IP Assignment with PPPoA or PPPoE Encapsulation If you have a dynamic IP, then the IP Address and Gateway IP Address fields are not applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and not the Gateway IP Address field. IP Assignment with RFC 1483 Encapsulation In this case the IP address assignment must be static. IP Assignment with ENET ENCAP Encapsulation In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and Gateway IP Address fields as supplied by your ISP. However for a dynamic IP, the P-794H acts as a DHCP client on the WAN port and P-794H User's Guide 129

virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be

dominant in environments where dynamic creation of large numbers of ATM VCs is

LLC-based Multiplexing

In this case one VC carries multiple protocols with protocol identifying information

being contained in each packet header. Despite the extra bandwidth and

processing overhead, this method may be advantageous if it is not practical to

have a separate VC for each carried protocol, for example, if charging heavily

depends on the number of simultaneous VCs.

7.6.3

VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel

Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255

and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM

traffic). Please see the appendix for more information.

7.6.4

IP Address Assignment

A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP

assigns you a different one each time. The Single User Account feature can be

enabled or disabled if you have either a dynamic or static IP. However the

encapsulation method assigned influences your choices for IP address and ENET

ENCAP gateway.

IP Assignment with PPPoA or PPPoE Encapsulation

If you have a dynamic IP, then the

IP Address

and

Gateway IP Address

fields

are not applicable (N/A). If you have a static IP, then you only need to fill in the

Address

field and not the

Gateway IP Address

field.

IP Assignment with RFC 1483 Encapsulation

In this case the IP address assignment must be static.

IP Assignment with ENET ENCAP Encapsulation

In this case you can have either a static or dynamic IP. For a static IP you must fill

in all the

IP Address

and

Gateway IP Address

fields as supplied by your ISP.

However for a dynamic IP, the P-794H acts as a DHCP client on the WAN port and
