dhcp is slow to deliver IP

[arodriguez_47]

Good morning, I have a problem with my ISR 4221 Router.

Cisco IOS XE Software, Version 16.12.03
Cisco IOS Software [Gibraltar], ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9_IAS-M), Version 16.12.3, RELEASE SOFTWARE (fc5)

when delivering ip addresses by dhcp, they take between 40 and 49 seconds.
Is there a way to decrease this? in other routers it gives it to me to the second

this log gives me after 40 seconds

how is the user connected ? how is your topology?

router--switch---user ? then looks like you need to configure on switchport portfast to minimize the delay.

or is the users from VPN ?

[arodriguez_47]

Hi Balaji

I am connected to a switch that goes directly to the router portfast is activated and the same thing happens. I connect a 2901 router with the same settings and the dhcp works out of the box.

Hello,

actually, it would be good to see the entire running configuration (sh run)...

Either way, what happens if you stop/start the dhcp service ?

4221(config)#no service dhcp

4221(config)#service dhcp

Hello

Wha tis the switch doing?

Does it have any security polices applied to it, check for physcal errors on the switch interaces, cabling etc.

[arodriguez_47]

Hello
The wiring is ok, when I replace the isr 4221 with a 2901 router, the dhcp works without problems

[balaji.bandi]

 I connect a 2901 router with the same settings and the dhcp works out of the box.

You mean instead of "ISR 4221 Router."  it works as expected  when you use in place of 4221 with 2901 router ?

Do you mind share full ISR 4221 Router. config here
