Symptom
Our DHCP Smart Relay documentation contains this guideline: "In a vPC environment with DHCP smart relay enabled, the subnet of the primary and secondary addresses of an interface should be the same on both Cisco NX-OS devices."
This could be incorrectly read to mean that the primary and secondary addresses of a single interface should be in the same subnet.
Conditions
This problem affects anyone who reads our DHCP configuration guides: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/93x/security/configuration/guide/b-cisco-nexus-9000-nx-os-security-configuration-guide-93x/b-cisco-nexus-9000-nx-os-security-configuration-guide-93x_chapter_01110.html
Workaround
There are no workarounds for this documentation issue.
Further Problem Description
I suggest amending the bullet point to read "If DHCP Smart Relay is enabled in a vPC environment, primary interface IP addresses should share a subnet between the peers. Secondary interface IP addresses should also share a subnet between the peers."
