I am seeing increasing input queue drops on a 7600 running 12.2(33)SRC5 on a SPA-2X1GE in a 7600-SIP-400. #sh int g1/1/1 GigabitEthernet1/1/1 is up, line protocol is up Hardware is GigEther SPA, address is 001d.7170.3500 (bia 001d.7170.3500) Description: Internet address is x.x.x.x/yy MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 72/255, rxload 46/255 Encapsulation ARPA, loopback not set Keepalive not supported Full Duplex, 1000Mbps, link type is force-up, media type is SX output flow-control is unsupported, input flow-control is unsupported ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 01:44:10 Input queue: 0/75/1707/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 183245000 bits/sec, 41346 packets/sec 5 minute output rate 283924000 bits/sec, 55078 packets/sec 256319513 packets input, 149816057859 bytes, 0 no buffer Received 5 broadcasts (0 IP multicasts) 0 runts, 1707 giants, 0 throttles 1707 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 0 multicast, 0 pause input 308870586 packets output, 193458081331 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier, 0 pause output 0 output buffer failures, 0 output buffers swapped out I also ran "sh int g1/1/1 switching" and it looks like the RP is dropping the packets. #sh int g1/1/1 switching GigabitEthernet1/1/1 Throttle count 0 Drops RP 1706 SP 0 SPD Flushes Fast 0 SSE 0 SPD Aggress Fast 0 SPD Priority Inputs 7257 Drops 0 Protocol Path Pkts In Chars In Pkts Out Chars Out Other Process 0 0 0 0 Cache misses 0 Fast 0 0 0 0 Auton/SSE 15978 958680 0 0 IP Process 80379934 7498092736 42273104 3084247027 Cache misses 0 Fast 68341283 5017154676 1197481 86714780 Auton/SSE 401843915443 245108148367129 516300637842 386876899705145 DEC MOP Process 0 0 31700 2440900 Cache misses 0 Fast 0 0 0 0 Auton/SSE 0 0 0 0 ARP Process 15978 958680 15866 951960 Cache misses 0 Fast 0 0 0 0 Auton/SSE 0 0 0 0 Any advice on troubleshooting? I looked at http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a0080094791.shtml and "show buffers input-interface g1/1/1 header" does not display any data and performing "debug ip packet" on a production router may not be in my best interests. :) - -- Devon -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkwrYxwACgkQWP2WrBTHBS+BUACfQ65VbBf9rWz7p2z952IvRp5q LpQAn0iRMn5Gv4vB26f+zcs8+ZwB1W5x =+tUx -----END PGP SIGNATURE----- _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
