Shows SMDS (Switched Multi-megabit Data Service) configuration and status.
show smds {config | runtime | state | statistics}
config | The show smds config command will display the SMDS configuration parameters for all the ports where SMDS is activated. |
runtime | The show smds runtime command will display the current SMDS configuration parameters for the particular WAN ports. The runtime values should be the same as those shown by the show smds config command. |
state | The show smds state command will display the state of the SMDS link for every port. The state can be Up or Down. A dash (-) is used to indicate that SMDS is not configured for that port. |
statistics | The show smds statistics command will display SMDS statistics. For statistics about the physical port that is sending or receiving SMDS encapsulated packets, use the show statistics serial command. |
The following sections describe the display contents for each command.
The show smds config display includes the following information:
Port | This column displays the physical interfaces where SMDS is activated. |
Station Address | This is the SMDS station address assigned by the service provider to the SMDS link for this interface. |
IPmulticast | This is the IP multicast address assigned to this interface. It is the same as the SMDS group address assigned by the SMDS provider to the link for this port. |
KeepAlive | This shows whether keepalive is activated or not and what the polling frequency is. |
The show smds statistics display includes the following information:
in | The number of packets with SMDS encapsulation that have been received through that particular WAN port. |
out | The number of packets with SMDS encapsulation that have been transmitted through that particular WAN port. |
heartbeat in | The number of keepalive answer packets received from the SMDS switch. |
heartbeat out | The number of keepalive poll packets sent by the router to the SMDS switch. |
discard | The number of packets with SMDS encapsulation that have been discarded from that particular WAN port. The number of discarded packets should be equal to the total number of err packets. The various err tallies signify encapsulation errors and may indicate an incorrect configuration or a problem with the SMDS switch. |
The following sections show an example for each command.
The following example displays are for the show smds config command:
Port Station Address IPmulticast Wan0 C111.1111.1111.FFFF E303.4444.4444.FFFF KeepAlive 10 Wan1 C222.2222.2222.FFFF E303.5555.5555.FFFF KeepAlive Off
The following example displays are for the show smds state command:
