In a VSX environment, what is the purpose of the command vsx-sync dhcp-relay?

• A. Synchronizes DHCP relay settings between VSX peers
• B. Enables DHCP server on the primary switch
• C. Clears DHCP leases on both switches
• D. Starts a new DHCP relay process

Answer: (A)

In a VSX setup, keeping configuration consistent between the two switches is essential for reliable operation. The vsx-sync dhcp-relay command makes sure the DHCP relay settings are the same on both VSX peers, so DHCP requests are forwarded in the same way no matter which switch handles them. This prevents situations where one member relays to a server while the other does not, which could cause IP address assignment failures or inconsistent behavior. It doesn’t enable a DHCP server on a switch, doesn’t clear DHCP leases, and doesn’t start a new DHCP relay process—the command’s role is simply to synchronize the existing relay configuration across the VSX pair.
