Kaspersky SD-WAN

Managing links

You can view the links in one of the following ways:

• To view the table of links established from a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, and select the Links tab.
• To view the table of all links, go to the Infrastructure menu section, click Management → Configuration menu next to the controller, and go to the Links section.
• To view the graphical topology with all links, go to the Infrastructure menu section, click Management → Configuration menu next to the controller, and go to the Topology section.

When viewing the table of links, information about the links is displayed in the following table columns:

• Source is the name, DPID, and OpenFlow port number of the CPE device that is the link source.
• NAT/Disjoint src is the IP address and port of the link source, separated by a colon.
• Source IP/port is the topological attribute of the link source, responsible for sending information about SD-WAN interfaces to the controller. Possible values:
  • N (Disabled. SD-WAN interface information is not sent to the controller).
  • NAT/PAT (the SD-WAN interface is behind NAT or PAT).
  • WAN disjoint (the SD-WAN interface is connected to an isolated network).
• Destination is the name, DPID, and OpenFlow port number of the CPE device that is the link destination.
• NAT/Disjoint dst is the IP address and port of the link destination, separated by a colon.
• Destination IP/port is the topological attribute of the link destination, responsible for sending information about SD-WAN interfaces to the controller. Possible values:
  • N (Disabled. SD-WAN interface information is not sent to the controller).
  • NAT/PAT (the SD-WAN interface is behind NAT or PAT).
  • WAN disjoint (the SD-WAN interface is connected to an isolated network).

  If necessary, you can hide all columns except Source, Source IP/port, NAT/Disjoint src, Destination, Destination IP/port, NAT/Disjoint dst by clicking the settings icon and selecting Show tunnel IPs in the menu.

• Last resort indicates whether the controller uses this link as the last resort when calculating the path, regardless of the monitoring indicators:
  • Y
  • N
• Threshold monitoring determines whether threshold monitoring on links is used. Possible values:
  • Y (monitoring enabled).
  • N (monitoring disabled).
• Encryption is the link encryption status. Possible values:
  • Configured
  • On
  • Off
• CFM is the time interval for sending control packets when Connectivity Fault Management is running. This column displays two values in the <value 1>/<value 2> format:
  • <value 1> is the time interval for sending control packets that you specified when you enabled CFM on the CPE device.
  • <value 2> -is the time interval for sending control packets that is currently being used. One of the following time intervals can be used for sending control packets:
    • The time interval for sending control packets that you specified when you enabled CFM on the CPE device. If you specify different time intervals for sending control packages on CPE devices, the largest of the specified time intervals is used. For example, if you specified 300 milliseconds as the control packet interval on CPE 1, and one second on CPE 2, the control packet interval is 1 second.
    • The time interval for sending control packets that you specified when you enabled CFM on the link. The time interval for sending control packets set for the link overrides the time intervals for sending control packets set on CPE devices. For example, if you specified 300 milliseconds as the control packet interval on CPE 1, one second on CPE 2, and 10 seconds on the link between CPE 1 and CPE 2, the resulting time interval for sending control packets is 10 seconds.

    Manually specified values in this column are underlined.

• MTU is the MTU value of the link.
• Errors/second is the number of errors per second on the link.
• Utilization (%) is the load of the link as a percentage of the bandwidth of the source service interface.
• Latency (ms) is the delay time in milliseconds for traffic transmitted through the link.
• Jitter (ms) is the jitter time in milliseconds for traffic transmitted through the link.
• Packet loss (%) is the percentage of traffic packet loss on the link.
• Speed (Mbit/sec) is the speed of traffic transmission through the link in Mbps.
• Cost is the link cost.

The actions you can perform with the table are described in the Managing solution component tables instructions.
