We have an ASR 9010 running IOS-XR v 5.1.3. We see a high level of input
discards:
TenGigE0/1/1/7 is up, line protocol is up
Interface state transitions: 25
Layer 1 Transport Mode is WAN
MTU 9028 bytes, BW 10000000 Kbit (Max: 10000000 Kbit)
reliability 255/255, txload 13/255, rxload 99/255
Encapsulation ARPA,
Full-duplex, 10000Mb/s, link type is force-up
output flow control is on, input flow control is on
Carrier delay (up) is 100 msec, Carrier delay (down) is 4000 msec
loopback not set,
ARP type ARPA, ARP timeout 04:00:00
Last input 00:00:00, output 00:00:00
Last clearing of "show interface" counters 1d13h
30 second input rate 3886868000 bits/sec, 392410 packets/sec
30 second output rate 527057000 bits/sec, 154557 packets/sec
55223825999 packets input, 63505398737673 bytes, 116320028 total
input drops
0 drops for unrecognized upper-level protocol
Received 111 broadcast packets, 1499584 multicast packets
0 runts, 0 giants, 0 throttles, 0 parity
10 input errors, 5 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
The config on the interface looks like this:
interface TenGigE0/1/1/7
mtu 9028
ipv4 unreachables disable
ipv6 nd dad attempts 5
ipv6 address 2001:798:28:20aa::6/126
monitor-session No1 ethernet
flow-control bidirectional
carrier-delay up 100 down 4000
load-interval 30
flow ipv4 monitor fmp-nfsen sampler fsm-nfsen ingress
transport-mode wan
ipv4 access-group catch13-ing ingress
!
Any clue would be helpful for us to begin to debug this issue.
Thanks,
Hank
