Two directly connected S series switches cannot communicate with each other after link aggregation is configured

0

Link aggregation on S series switches (except the S1700) increases bandwidth and balance load among member interfaces. When two directly connected S series switches cannot ping each other, you need to check the router and IP address configuration.

Can VSs directly communicate with each other
Each VS can be considered an independent device. VSs cannot directly communicate even if they reside on the same physical device. VSs can directly communicate only when they are connected using physical ports, similar to the direct communication between physical devices.

ARs configured with IPSec on two private networks cannot communicate with each other
The possible causes are as follows: 1. The public addresses of two IPSec-enabled ARs cannot be pinged. 2. There is an error in the data flow to be encapsulated with the IPSec header or both IPSec and NAT are performed for the same data flow. You can run the display acl all command to check ACL matching. If both IPSec and NAT are performed for the same data flow, use either of the following method to prevent data flow overlapping: -Ensure that the destination IP address denied in the ACL rule referenced by NAT is the destination IP address in the ACL rule referenced by IPSec. By doing so, the device does not perform NAT on the data flow protected by IPSec. -The ACL rule referenced by IPSec matches the NAT-translated IP address. 3. The AR incorrectly learns private routes. The outbound interface of the route to the destination private network is not the public network interface enabled with IPSec.

Can two network segments that cannot communicate with each other be configured for two network ports of the VCN3000?
No. There can be only one VCN3000 service IP address. The two service network ports can be configured to work in active/standby or load balancing mode and show the same service IP address.
