Duplicate MAC Addresses for VPCS in Remote and Local Environments

[fresvel]

Description: When creating a VPCS instance in GNS3 both locally and remotely, the system assigns the same MAC address to both instances, causing a MAC address duplication. This issue occurs despite the expectation that each instance of VPCS, whether local or remote, should have a unique MAC address. The duplication of MAC addresses leads to network connectivity issues.

Steps to Reproduce:

Create a VPCS instance to run locally in GNS3.
Create a VPCS instance to run remotely (on a remote server).
Check the MAC address of both VPCS instances (using the show ip command or a similar method).
The MAC address of both instances will be the same.

Expected Behavior: Each VPCS instance, whether local or remote, should automatically be assigned a unique MAC address when created.

Actual Behavior: The MAC address is duplicated between the local and remote VPCS instances, leading to network issues.

Environment:

GNS3 Version: 2.2.50
Operating System Local: Rocky Linux 9.5
Operating System Remote: Windows 11

Additional Notes:

This issue is observed when creating VPCS instances in a network using both local and remote setups.
There is no apparent way to change the MAC address manually via the GNS3 GUI for VPCS instances.
