This chapter explains the function and syntax of the SMDS commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Cisco IOS Wide-Area Networking Command Reference, Release 12.1.
To enable Address Resolution Protocol (ARP) entries for static routing over the Switched Multimegabit Data Service (SMDS) network, use the following variation of the arp global configuration command. To disable this capability, use the no form of this command.
arp ip-address smds-address smds
Syntax Description
ip-address IP address of the remote router. smds-address 12-digit SMDS address in the dotted notation nnnn.nnnn.nnnn (48 bits long). smds Enables ARP for SMDS.
To enable Switched Multimegabit Data Service (SMDS) on the desired interface, use the encapsulation smds interface configuration command.
encapsulation smdsSyntax Description
This command has no arguments or keywords.
To define a logical subinterface on a serial interface to support multiple logical IP subnetworks over Switched Multimegabit Data Service (SMDS), use the interface serial multipoint interface configuration command.
interface serial {interface | slot/port}.subinterface multipoint
Syntax Description
interface Interface number. slot/port Slot and port number related to specified subinterface (for Cisco 7000 and 7500 series routers). .subinterface Number for this subinterface; values in the range 0 to 255.
To display the individual addresses and the interface they are associated with, use the show smds addresses privileged EXEC command.
show smds addressesSyntax Description
This command has no arguments or keywords.
To display all Switched Multimegabit Data Service (SMDS) addresses that are mapped to higher-level protocol addresses, use the show smds map privileged EXEC command.
show smds mapSyntax Description
This command has no arguments or keywords.
To display statistics about Switched Multimegabit Data Service (SMDS) packets the router has received, use the show smds traffic privileged EXEC command.
show smds trafficSyntax Description
This command has no arguments or keywords.
To specify the Switched Multimegabit Data Service (SMDS) individual address for a particular interface, use the smds address interface configuration command. To remove the address from the configuration file, use the no form of this command.
smds address smds-address
Syntax Description
smds-address Individual address provided by the SMDS service provider. It is protocol independent.
To enable the Data Exchange Interface (DXI) version 3.2 support, use the smds dxi interface configuration command. To disable the DXI 3.2 support, use the no form of this command.
smds dxiSyntax Description
This command has no arguments or keywords.
Syntax Description
This command has no arguments or keywords.
To enable dynamic address mapping for Internet Packet Exchange (IPX) over Switched Multimegabit Data Service (SMDS), use the smds glean interface configuration command. To disable dynamic address mapping for IPX over SMDS, use the no form of this command.
smds glean protocol [timeout-value] [broadcast]
Syntax Description
protocol Protocol type. Only IPX is supported. timeout-value (Optional) Time to live (TTL) value. Value can be from 1 to 65535 minutes. The default is 5 minutes. This value indicates how long a gleaned dynamic map is stored in the SMDS map table. broadcast (Optional) Marks the gleaned protocol address as a candidate for broadcast packets. All broadcast requests are sent to the unicast SMDS address.
Syntax Description
protocol Protocol type. smds-address SMDS address. Because SMDS does not incorporate broadcast addressing, a group address for a particular protocol must be defined to serve the broadcast function.
To map the Switched Multimegabit Data Service (SMDS) address to a multicast address, use the smds multicast arp interface configuration command. To disable this feature, use the no form of this command.
smds multicast arp smds-address [ip-address mask]
Syntax Description
smds-address SMDS address in E.164 format. ip-address (Optional) IP address. mask (Optional) Subnet mask for the IP address.
To enable spanning-tree updates, use the smds multicast bridge interface configuration command. To disable this function, use the no form of this command.
smds multicast bridge smds-address
Syntax Description
smds-address SMDS multicast address in E.164 format.
To map an Switched Multimegabit Data Service (SMDS) group address to a secondary IP address, use the smds multicast ip interface configuration command. To remove the address map, use the no form of this command.
smds multicast ip smds-address [ip-address mask]
Syntax Description
smds-address SMDS address in E.164 format. ip-address (Optional) IP address. mask (Optional) Subnet mask for the IP address.
To configure a static map between an individual Switched Multimegabit Data Service (SMDS) address and a higher-level protocol address, use the smds static-map interface configuration command. To remove the map, use the no form of this command with the appropriate arguments.
smds static-map protocol protocol-address smds-address [broadcast]
Syntax Description
protocol protocol-address Address of the higher-level protocol. smds-address SMDS address, to complete the mapping. broadcast (Optional) Marks the specified protocol address as a candidate for broadcast packets. All broadcast requests are sent to the unicast SMDS address.
