Hi All I have been seeing some crazy stuff happening on a Cisco 887W Router since I brought it online. I am seeing the txload on the Dialer interface running at 255/255 the whole time, even with all LAN interfaces shut. Upon further investigation, I can see this is all ppp over atm traffic show interfaces d0 accounting Dialer0 Protocol Pkts In Chars In Pkts Out Chars Out IP 8481 686517 10750 4189699 PPP over ATM 0 0 13282269238568943991 2542327207066529655 #show int atm0 ATM0 is up, line protocol is up Hardware is MPC/AOE ATMSAR, address is c464.1356.0e80 (bia c464.1356.0e80) MTU 1600 bytes, sub MTU 1600, BW 1080 Kbit/sec, DLY 340 usec, reliability 255/255, txload 1/255, rxload 255/255 Encapsulation ATM, loopback not set Keepalive not supported Encapsulation(s): AAL5 4 maximum active VCs, 1024 VCs per VP, 1 current VCCs VC Auto Creation Disabled.

Cisco IOS Software, C800 Software (C800-UNIVERSALK9-M), Version 15.1(4)M3 Any idea's at all guys? I have a few of these routers with this issue, but yet on a slightly older model with same config everything is fine Many thanks
