SMDS

This section is used to configure SMDS (Switched Multi-megabit Data Service) parameters for either the interface specified or for multiple interfaces using the default sections as explained in Appendix , "Default Sections and Default Values." SMDS is a connectionless, packet-switched service that offers LAN-to-LAN connectivity across a wide area at up to 1.544 Mbps. SMDS is enabled in the Link Config section.

Syntax Description

WAN slot:port

Ports are numbered starting with 0, so for a module with one port, the port is 0. For theVPN 5008 chassis, slot 0 is the far left slot. For the VPN 5002 chassis, slot 0 is the top slot.

Keywords

After entering the configure command for the section, enter one or more of the following keywords.

StationAddress = String	The StationAddress keyword is used to configure the SMDS physical station address. The address is assigned by the service provider and follows the E.164 format (i.e., 64-bit/15-digit addressing). The station address must start with the letter C and be followed by at least 10 digits.The missing digits will be filled in with F. The address should be entered exactly as it is assigned by the service provider.
IPMulticast = String	The IPMulticast keyword is used to configure the IP multicast address. This address is the SMDS group address assigned by the service provider and follows the E.164 format. The multicast address must start with the letter E and be followed by at least 10 digits. The missing digits will be filled in with F. The address should be entered exactly as it is assigned by the service provider.
PollingFrequency = Number	The PollingFrequency keyword specifies the interval that the router uses to poll the SMDS switch. The interval is specified in seconds and must be between 0 and 30. If the switch does not respond to the polling, the router will eventually declare the SMDS link down and start dropping packets designated for that interface. A value of 0 will disable the polling mechanism. Disabling the polling mechanism will automatically declare the SMDS link up. Note   The keepalive mechanism is also referred to as "heartbeat exchange" in the SMDS literature.

Examples

The following is an example of a valid StationAddress setting:

StationAddress = C130.3302.1310
 

The following is an example of IPMulticast setting:

IPMulticast = E130.3302.4139
