What Are Common Troubleshooting Methods for Direct Connect?

Connectivity Issues
If network connectivity is abnormal after you have connected the leased line to the endpoint device, perform the following steps to locate the fault:
- Verify that the network device is connected correctly, auto-negotiation is disabled for the optical port, and the port speed and full-duplex mode are configured correctly.
- Verify that optical signals can be normally transmitted and received.
Network Issues
If the connection fails to work normally after you created a virtual interface to connect your on-premises network to the loud, perform the following steps to locate the fault:
- Verify that the local gateway can be pinged from the remote gateway and that the VLAN of the intermediate device is configured correctly.
- Verify that IP addresses of the local and remote gateways are in the same CIDR block and are configured on the VLAN sub-interfaces.
- If static routing is used, verify that the next hop or outbound interface of the static route is configured correctly.
- If BGP routing is used, verify that:
- BGP ASN, BGP MD5 authentication key, and BGP peer IP address are configured correctly.
- BGP ASNs on both gateways are different.
- There are no more than 100 BGP routes propagated through the virtual interface.
- There are no rules for prohibiting TCP port 179 or dynamic TCP ports.
Routing Issues
If static routes have been delivered for the virtual interface or a BGP peer relationship has been established, perform the following steps to locate the fault:
- Verify that the routes between your gateway and your on-premises network are reachable.
- Verify that the routes to your on-premises network are propagated and correctly configured in the remote subnet of the virtual interface, and that BGP routes are used to route traffic to your on-premises network if you select BGP routing.
- Verify that the VPC CIDR block is correctly configured on the virtual gateway.
- Verify that the security group and network ACL rules allow inbound and outbound traffic.
