I am trying to add a DHCP server to a switch (config in text). The DHCP server is not responding on the VLAN interface. Does anyone know a way to resolve this? “show dhcp” server gives the following:

 

IPv4 DHCP server is inactive
DNS server(s): 8.8.8.8
Lease duration: 0 days 2 hours 0 minutes
Active leases: 0
IPv4 DHCP interface status:
Interface Status
————— ——

Subnet: 10.10.8.0/22
Range: 10.10.8.101 to 10.10.8.149
DNS server(s): 8.8.8.8
Default gateway address: 10.10.8.1
Active leases: 0

Hi Christopher,

 

Thank you for writing to the forum. In the config snippet, the "dhcp server ipv4" is missing under interface VLAN 10. Here, I am assuming that you require VLAN 10 to lease out the IP addresses based on IP addressing scheme.

More about the configuration can be seen here: https://eos.arista.com/eos-4-23-1f/dhcp-server-on-eos/

If it does not work, please share the output of:

Hope that helps,

Thank you,
