Setting up a 1335 as a DHCP Server for Multiple Subnets

Jump to solution

Hello,

  I am trying to verify a current configuration in a 1335. I have 4 vlans in this 1335 10,50,192 and 200 I need the Netvanta to be a DHCP server for vlan 192 (customer data network) and 200 (voice network). Just want to make sure the DHCP scopes look correct before deployment. Ports 16-24 configured for voice the two DHCP Scopes.

Thanks

Thank you for asking this question, and for attaching the configuration.  Based on the information you provided, the configuration appears to be correct.  It will act as a DHCP-server for VLANs 192 and 200 (here is the Configuring QoS in AOS document for reference).

I have a couple recommendations.  First, I would remove the command ip helper-address 192.168.200.2 from the VLAN 200 interface.  Since, you do not appear to be doing any form of UDP-relay, this command should be removed.  Second, depending on what phones you are using, you may need to disable LLDP.  If the phones do not support LLDP-MED (here is the Configuring LLDP-MED in AOS document for reference), then you should remove this functionality from the interfaces:

ROUTER-NAME(config-swx 0/x)# no lldp send-and-receive

Please, reply if you have additional questions about this topic area.
