Hi All, I have a strange flow issue for a number of our ATM customers. The config is identicle for all customers but what I'm finding is that flows for certain customers are not being collected in the download direction to the customer. 1/ Working example: Me pinging customer RED's IP (210.15.230.BB) from my shell (210.15.210.XX): > ping 210.15.230.BB PING 210.15.230.BB (210.15.230.BB): 56 data bytes 64 bytes from 210.15.230.BB: icmp_seq=0 ttl=62 time=4.902 ms 64 bytes from 210.15.230.BB: icmp_seq=1 ttl=62 time=4.498 ms
I'm seeing bi-drectional flows, all is good: agr1-ks-mel#sh ip cache flow | inc 210.15.210.XX Gi0/0.11 210.15.210.XX AT1/0.303693 210.15.230.BB 01 0000 0800 5 AT1/0.303693 210.15.230.BB Gi0/0.11 210.15.210.XX 01 0000 0000 5 Interface config for customer RED: interface ATM1/0.303693 point-to-point description Customer RED bandwidth 4000 ip address 210.15.230.AA 255.255.255.224 ip flow ingress atm route-bridged ip no atm enable-ilmi-trap pvc 10/208 ubr 4096 encapsulation aal5snap 2/ Non Working Example Me pinging customer BLUE's IP (210.15.225.KK) from my shell (210.15.210.XX): > ping 210.15.225.KK PING 210.15.225.KK (210.15.225.KK): 56 data bytes 64 bytes from 210.15.225.KK: icmp_seq=0 ttl=61 time=9.820 ms 64 bytes from 210.15.225.KK: icmp_seq=1 ttl=61 time=9.379 ms Only seeing one way flow in the upload direction, not so good (because we don't bill for this data). agr1-ks-mel#sh ip cache flow | inc 210.15.210.XX AT1/0.305357 210.15.225.KK Gi0/0.11 210.15.210.XX 01 0000 0000 5 Interface config for customer BLUE: interface ATM1/0.305357 point-to-point description Customer BLUE bandwidth 2000 ip address 210.15.225.JJ 255.255.255.224 ip flow ingress atm route-bridged ip no atm enable-ilmi-trap pvc 10/356 ubr 2048 encapsulation aal5snap I don't get it. Identicle configs but we don't see bi-directional flows for customer BLUE??? Here's the physical ATM config: interface ATM1/0 bandwidth 155000 no ip address ip flow ingress no ip mroute-cache load-interval 30 no atm auto-configuration no atm ilmi-keepalive no atm address-registration no atm ilmi-enable no atm enable-ilmi-trap We are running 12.2(31)SB13 on a 7301. Just wondering if anyone's seen this before or have any ideas what might be causing this. Thanks.
