Cisco 886G DHCP interface reset

[Joris Deprouw]

Hello,

We have a Cisco 886G router connected to the internet. The router receives an ip address.

We experience however a problem when the lease time expires.

The router does not send a DHCP request to renew it's ip address in time. This causes an interface reset, and connectivity loss, after the lease time of 8 hours.

Has anyone experienced this problem?

We are running IOS 880data-universalk9-mz.151-3.T.bin

Config on DHCP receiving interface is:

interface VlanX
description To Internet MODEM
ip address dhcp
ip access-group TEST in
!

Thanks,

Best Regards,

joris
