Hi I have installed WS-X6348-RJ-45 card in Catalyst 6500/Sup32 and I saw increasing output drops on each FE interface. Currently I'm using only 3 ports on this card (Fa1/1, Fa1/2, Fa1/48). Avarage traffic level on each port is about 10-20Mbps. I also didn't saw large traffic peaks like >80Mb on MRTG graphs (with WithPeak option switched-on) of these ports.
So, what causing Output drops on this card ? Here is output of show interface: FastEthernet1/1 is up, line protocol is up (connected) Hardware is C6k 100Mb 802.3, address is 0001.c96a.8e84 (bia 0001.c96a.8e84) Description: Customer DataTech MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, reliability 255/255, txload 31/255, rxload 65/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s input flow-control is off, output flow-control is unsupported ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output never, output hang never Last clearing of "show interface" counters 7w3d Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 19674562 Queueing strategy: fifo Output queue: 0/40 (size/max) 30 second input rate 25559000 bits/sec, 10902 packets/sec 30 second output rate 12205000 bits/sec, 13481 packets/sec 24149904901 packets input, 10099290976969 bytes, 0 no buffer Received 7617 broadcasts (7617 multicasts) 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 0 multicast, 0 pause input 0 input packets with dribble condition detected 29324673054 packets output, 3831810881262 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 FastEthernet1/48 is up, line protocol is up (connected) Hardware is C6k 100Mb 802.3, address is 0001.c96a.8e86 (bia 0001.c96a.8e86) Description: sw3 MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, reliability 255/255, txload 105/255, rxload 51/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s input flow-control is off, output flow-control is unsupported ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output never, output hang never Last clearing of "show interface" counters 7w3d Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 2032436 Queueing strategy: fifo Output queue: 0/40 (size/max) 30 second input rate 20003000 bits/sec, 6993 packets/sec 30 second output rate 41324000 bits/sec, 7807 packets/sec 25171862715 packets input, 9131681778867 bytes, 0 no buffer Received 493121 broadcasts (160311 multicasts) 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 0 multicast, 0 pause input 0 input packets with dribble condition detected 28744492098 packets output, 19704727289126 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 interface FastEthernet1/1 description Customer DataTech switchport switchport access vlan 604 switchport mode access no ip address logging event link-status load-interval 30 no cdp enable spanning-tree portfast spanning-tree bpdufilter enable ! interface FastEthernet1/2 description MGMT SDH switchport switchport access vlan 2150 switchport mode access no ip address logging event link-status load-interval 30 speed 10 no cdp enable spanning-tree portfast ! ... interface FastEthernet1/48 description sw3 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 136,338,622,1810 switchport mode trunk switchport nonegotiate no ip address logging event link-status logging event bundle-status logging event trunk-status load-interval 30 speed 100 duplex full no cdp enable spanning-tree portfast trunk spanning-tree bpdufilter enable !
