Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M) - DHCP Server

[victorinorj]

Hello!

I need help configuring a DHCP server on a C4507R ( Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M)).
The SVIs are configured on this switch.
vlan interface configuration
vlan5 interface
description mkp
ip address 10.2.5.254 255.255.255.0
no ip redirects
ip pim dense-mode
!
DHCP Server Configuration.
ip dhcp pool teste_pela_rede_video_conf
network 10.2.5.0 255.255.255.0
default-router 10.2.5.254

The cat4000 cannot configure the exclusion of the ipadress the interface vlan5.
The pool will deliver the ipaddress the interface vlan5. How to avoid?

Hi @victorinorj ,

This is a quote from the IOS configuration guide.

"The IP address configured on the router interface is automatically excluded from the DHCP address pool."

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dhcp/configuration/12-4/dhcp-12-4-book/config-dhcp-server.html

So, you should be fine.

no need exclude, the client/server after get same IP of SVI, it will send G-ARP and SW will reply and hence the IP will reject and client will get new IP.
