The log of one of our dsl-routers shows a lot of this messages:
*Oct 9 11:11:21 MEST: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to down
*Oct 9 11:13:49 MEST: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up
*Oct 9 11:14:52 MEST: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to down
*Oct 9 11:15:14 MEST: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up
No errors at the hardware interface.
How to debug this issue?
The config of the interface:
interface Dialer1
ip address negotiated
ip mtu 1492
encapsulation ppp
ip tcp adjust-mss 1000
dialer pool 1
no cdp enable
ppp authentication pap callin
ppp pap sent-username nc-xxxxxxx password 7 040A26502D0761
crypto ipsec client ezvpn WAHN-VPN
end
Thank you for your help
