Remote Diagnostic Tests on Edges

VeloCloud Orchestrator allows running various remote diagnostics tests on a selected Edge. The remote diagnostic information contains Edge-specific logs for analysis.

This topic contains the following sections:

ARP Table Dump

What is the purpose of this test?

Run this test to:
  • Verify the IP address to MAC address binding on the LAN/WAN interfaces that are connected to the Edge on which the test is run.
  • View the status of the ARP cache.

When can a user run this test?

The following are the scenarios when a user can run this test:
  • Clients in the same broadcast domain are not reachable.
  • Interface device not reachable.
  • Next hop is not reachable.

What to check in the test output.

Run the ARP Table Dump test on the required Edge. For instructions, see Run Remote Diagnostic Tests on Edges.

Following is an example of the test output:

Figure 1. ARP Table Dump
The output is limited to displaying 1000 ARP entries. Following are the possible ARP cache statuses:
  • Alive- Interface is reachable.
  • Dead- Interface is not reachable.
  • Refresh- Interface is trying to relearn the ARP.

To identify the cause for the device reachability issue:

  1. In the output of the ARP Table Dump test, verify the ARP cache status of the interface.

    If the status is of any value other than Alive, run the Clear ARP Cache test to clear the cache of the previously stored ARP value.

    Note: The user can clear the ARP cache for only one interface at a time.
  2. Run the ARP Table Dump test again to verify the IP address and the MAC address mapping on the LAN/WAN interface.
  3. If the problem persists, collect Diagnostic and Packet Capture bundles and contact Arista Customer Support. See Diagnostic Bundles for Edges with New Orchestrator UI.

Clear ARP Cache

What is the purpose of this test?

Clears specific interface-learned ARP entries from the ARP table.

When can the user run this test?

This test is run when there are stale entries in the ARP table dump test. For instructions, see Run Remote Diagnostic Tests on Edges.

What to check in the test output.

Run the Clear ARP Cache test on the required Edge. Following is an example of the test output:
Figure 2. Clear ARP Cache

Ping IPv6 Test

What is the purpose of this test?

Verifies if the next hop or an IPv6 address is reachable from the interface.

When can a user run this test?

Run this test to check the following:
  • IPv6 reachability
  • Packet Loss
  • RTT

For instructions, see Run Remote Diagnostic Tests on Edges.

What to check in the test output.

Run the Ping IPv6 test on the required Edge. Check if the output displays Reachable. For a successful PING test, the number of packets transmitted must equal the number received. If not, capture the Interface and Destination IP addresses to see where the packet is getting dropped. Following is an example of the test output:

Figure 20. List Active Firewall Sessions
Users can verify denied traffic of the firewall under Monitor > Firewall logs .
Figure 21. Firewall Logs

 

The Remote Diagnostics output displays the following information:
Table 2. Remote Diagnostics Field Descriptions
Field Description
Segment Specifies the segment in which the Edge processes the firewall session. Users can also filter the output based on a specific segment.
Src IP Specifies the source IP that initiated the firewall session.
Dst IP Specifies the destination IP of the firewall session.
Protocol Specifies the protocol used by the firewall session traffic.
Src Port Specifies the source port of the firewall session traffic.
Dst Port Specifies the destination port of the firewall session traffic.
Application Specifies the application that the Application engine/Deep Packet Inspection (DPI) engine identifies.
Firewall Policy Specifies the firewall rule that the session matches among the configured firewall rules.
TCP State Specifies the current Transmission Control Protocol (TCP) state of the session. In the output, users will see the current TCP state for each flow. There are 11 distinct TCP states as defined in RFC 793:
  • SERVER_LISTEN - indicates the initial state of the TCP FSM on the Edge. This state is not shown in the Remote Diagnostic output because it is the default state when the system creates a session for the flow's first packet. When the system detects a SYN packet, it immediately moves the flow to the SYN_SENT state.
  • SYN_SENT - Session moves to this state when users see a connection request SYN from the Client to the Server.
  • SYN_RECEIVED- indicates that the system detected a SYN+ACK packet from the server side.
  • ESTABLISHED - indicates a state after a 3-way handshake, completing Acknowledgement(ACK) from the Client side. Session is now ready for the data transfer phase.
  • CLIENT_FIN - From the ESTABLISHED state, the transition to CLIENT_FIN occurs after the system receives the FIN from the Client. In this state, only FIN or ACK retransmissions are allowed from the Client side. But on the Server side, all packets are allowed, except FIN packets, which move the state to CLOSING.
  • SERVER_ FIN - From the ESTABLISHED state, the system transitions to the SERVER_FIN state after receiving the FIN from the Server. In this state, only FIN or ACK retransmits are allowed from the Server side. But on the Client side, all packets are allowed, except FIN packets, which move the state to CLOSING.
  • CLOSING - indicates that the system received a FIN (Finish) packet from both the client and the server. In this state, only SYN packets can reopen the session.
  • CLOSED - indicates that the system received a Reset (RST) packet from either the client or the server to terminate the connection abruptly. After the Gateway identifies this state, it drops all subsequent packets for that flow unless it detects a new SYN packet to re-establish the session.
Bytes Sent Specifies the firewall session traffic from source IP to destination IP in Bytes.
Bytes Received Specifies the firewall session traffic from the destination IP to the source IP in Bytes.
Duration Specifies the age of the firewall session in seconds.

IPv6 Clear ND Cache

What is the purpose of this test?

To clear specific interface learned neighbor entries and their associated Layer 2 information, run the IPv6 Clear Neighbor Discovery (ND) cache command.

    • Reachable - This status indicates that the system recently updated the neighbor information and is currently using it for active communication.
    • Stale - This status indicates that the system collected neighbor information in the past but is not currently utilizing it for active traffic.

IPv6 Route Table Dump

What is the purpose of this test?

The IPv6 Route Table Dump command lists the entire IPv6 routing table.

When can you run this test?

Run this test if the user wants to verify the Route in the Forwarding Information Base (FIB) table of IPv6. The user can run the test by specifying any of the following options:

Next Hop Name Specifies the name of the next hop device.
Destination Name Specifies the name of the destination device.
Lost Reason Specifies the codes for different reasons the route is lost to the next preferred route on the Edge.
(Not) Reachable Reason Specifies the reason for the route being reachable or not reachable.
Note: An unresolved route, learned over multi-hop BGP, might point to an intermediate interface.
The following table lists the reason codes and the corresponding description:
Table 4. Reason Code Descriptions
Reason Code Description
PR_UNREACHABLE For overlay routes, the remote peer, whether Gateway or Edge, is unreachable.
IF_DOWN The egress interface is down.
INVALID_IFIDX The egress interface if-index for this route is invalid.
SLA_STATE_DOWN The state given by IP SLA tracking is down.
HA_STANDBY While the local Edge acts as a Standby, it marks all routes synced from the Active node as reachable to provide operational convenience.
LOCAL_MGMT Management routes are always reachable.
LOOPBACK The Loopback IP address is always reachable.
SELF_ROUTE Self IP routes are always reachable.
RECUR_UNRES The system marks recursive routes as reachable to enable recursive resolution, which provides greater operational convenience.
VPN_VIA_NAT vpnViaNat routes are always reachable.
SLA_STATE_UP State given by IP SLA tracking is up.
IF_RESOLVED Egress interface is up and resolved.
PR_REACHABLE For overlay routes, the remote peer, whether Gateway or Edge, is reachable.

Flush DNS Cache

What is the purpose of this test?

Although the system triggers a DNS cache cleanup every 10 minutes, it only removes entries with a Time-to-Live (TTL) of zero or less. The DPI-based entries are initially cached with a TTL of 24 hours and remain in the cache for at least that long, preventing new entries from being learnt. This prevents reliable DNS lookups to support domain-based business policies. The Flush DNS Cache test clears the cache, freeing space for new entries and ensuring domain-based business policies remain reliable.

When can you run this test?

To clear all DNS cache entries from a specific Edge, run the Flush DNS Cache test on that Edge. For instructions, see Run Remote Diagnostic Tests on Edges.

What to check in the test output?

To confirm that the Edge has successfully cleared all DNS cache entries, users should run the Flush DNS Cache diagnostic test and then review the DNS table.

The following is an example of the test output:
Figure 25. Flush DNS Cache

Flush Flows

What is the purpose of this test?

To flush all current active sessions/specific flows in the device.

When can you run this test?

When specific traffic is not hitting the correct business policy or is having issues with the specific flow.

Run the Flush Firewall Sessions test on the required Edge, specifying the Source or Destination IP address or both. For instructions, see Run Remote Diagnostic Tests on Edges.

What to check in the test output?

Verify that the flows flushed match the flows seen. This would create a minor and temporary blip in the network.

The following is an example of the test output:

Figure 26. Flush Flows

Flush NAT

What is the purpose of this test?

To remove all the existing Network Address Translation (NAT) entries from the device.

When can you run this test?

Run this test if the NAT table contains an improper NAT entry or if users have NAT-related issues. For instructions, see Run Remote Diagnostic Tests on Edges.

What to check in the test output?

When users flush the NAT table, the system immediately clears all active translation entries, which disrupts current traffic flows.

The following is an example of the test output:

Figure 27. Flush NAT

MY Traceroute

What is the purpose of this test?

MTR (My Traceroute) is a diagnostic tool that combines Ping and Traceroute. Like Traceroute, it discovers the path to the destination and also sends packets continuously and measures latency and packet loss, similar to ping.

This tool helps to diagnose the network problem by highlighting packet drop, latency, and it also helps to identify the problem location (destination or intermediate hops issue).

When can the user run this test?

Run the MTR (My Traceroute) test to the specified destination with configurable ports and protocols for understanding routing or network reachability issues. For instructions, see Run Remote Diagnostic Tests on Edges.

What to check in the test output.

Run the MTR (My Traceroute) test on the required Edge by specifying the following parameters:
  • Segment - Select the specific segment to run the MTR (My Traceroute) test.
  • Destination - Specify the destination IP address or hostname to check network reachability.
  • MTR Using - Select a WAN/VLAN/LAG interface as source interface for the selected segment. The drop-down list filters and displays interfaces bounded to the selected segment.
  • Packet Count - Specify the count of MTR packets to be sent to the destination. The supported range is between 1 to 100, with the default value of 10.
  • Protocol - Select the protocol (ICMP/TCP/UDP) for sending the MTR packet. The default is ICMP.
  • Source Port - Specify the Source port for the MTR packet. This is optional for ICMP protocol.
  • Dest Port - Specify the Destination port for the MTR packet. This is optional for ICMP protocol. The default Traceroute Destination port is 33434.
  • Path - Select the path for the MTR traffic. The supported options are Direct, Multipath, NVS via Edge or NVS via Gateway, if configured. The default value is Direct. For NVS via Edge or NVS via Gateway, select the NVS tunnel.

Following are the examples of the test output:

    State Description
    Idle BGP resources are initialized by the router. BGP inbound connection attempts are refused. BGP initiates a TCP connection to the peer.
    Connect BGP waits for the 3WHS to complete. If successful, the OPEN message is sent to the peer, and BGP moves to the OpenSent state. If unsuccessful, BGP continues to the Active state. However, if the ConnectRetry expires, BGP remains in this state, with the timer being reset and a new 3WHS being initiated.
    Active The ConnectRetry timer is reset, and BGP returns to the Connect state.
    OpenSent BGP waits for an OPEN message from its peer. Once received, BGP moves to the OpenConfirm state.
    OpenConfirm BGP waits for a keepalive message from its peer. If the message is received before the timeout expires, BGP moves to the Established state. Otherwise, BGP transitions to Idle.
    Established Both peers exchange UPDATE messages. If there is an error within any of the UPDATE messages, the BGP peer sends a NOTIFICATION message and enters the Idle state.

NTP Dump

What is the purpose of this test?

Run this test to verify the date, time, and NTP server details used by the Edge.

When can you run this test?

Run this test if users have issues with the date and time in logs and the system time. The system uses UTC timestamps to maintain a consistent reference point across globally distributed networks. For instructions on how to run a remote diagnostic test on Edges, see Run Remote Diagnostic Tests on Edges.

What to check in the test output?

The following is an example of the test output:
Figure 79. NTP Dump

In the output, check the following:

  1. Verify that the date and time are correct in UTC format.

  2. Verify that the system peer matches the one mentioned in the NTP configuration.
  3. The Leap Indicator indicates if an impending leap second is to be inserted or deleted in the last minute of the current day. Therefore, if the leap second occurs, the NTP client running is one second ahead or the seconds mentioned in the leap indicator than the actual time.
  4. Stratum is the distance between Edge and NTP server. Lesser the Stratum number closer the server is. If the Stratum number is above 16 then it is considered to be unsynchronized.
  5. If the clock is unsynchronized, change the NTP server or PCAPs to determine whether the Edge receives the NTP sync request.
