DESCRIPTION

EXAMPLE

 

supports both IGMP version 1 (IGMP-v1) and version 2 (IGMP-v2).

 

 

Press the [SPACE BAR] to enable IP Multicasting or select None

 

 

to disable it.

 

 

 

 

IP Policies

Create policies using SMT menu 25 (see the IP Policy Routing

2,4,7,9

 

chapter) and apply them on the Prestige LAN interface here. You

 

 

can apply up to four IP Policy sets (from twelve) by entering their

 

 

numbers separated by commas.

 

Edit IP Alias

The Prestige supports three logical LAN interfaces via its single

No

 

physical Ethernet interface with the Prestige itself as the gateway for

(default)

 

each LAN network. Press [SPACE BAR] to change No to Yes and

 

 

press [ENTER] to for menu 3.2.1

 

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to save your configuration, or press [ESC] at any time to cancel.

3.9VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers supplied by your telephone company. 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 Appendices for more information.

3.10 Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.

3.10.1 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.

3.10.2 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
