“show interface gig0/0”, adjust the interface numbers appropriately.
Here is from one of my routers:
GigabitEthernet0/2 is up, line protocol is up
Hardware is BCM1250 Internal MAC, address is xxxx.xxxx.xxxx (bia xxxx.xxxx.xxxx)
Description: -Internal Network-
Internet address is xx.xx.xx.xx/xx
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 37/255, rxload 3/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full Duplex, 1Gbps, media type is RJ45
output flow-control is XON, input flow-control is XON
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 21w0d
Input queue: 0/75/0/223 (size/max/drops/flushes); Total output drops: 1262
Queueing strategy: fifo
Output queue: 0/40 (size/max)
30 second input rate 14604000 bits/sec, 9338 packets/sec
30 second output rate 146679000 bits/sec, 14297 packets/sec
3190992794 packets input, 225247867 bytes, 0 no buffer
Received 5349037 broadcasts (2747875 IP multicasts)
0 runts, 0 giants, 0 throttles
11 input errors, 0 CRC, 0 frame, 8 overrun, 0 ignored
0 watchdog, 12593127 multicast, 0 pause input
1945505025 packets output, 677645279 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
442 unknown protocol drops
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
As you can see, I’ve had 1262 output drops (tx discards) over the last 21 weeks… but it’s not something that really bothers me as this is an ISP Border router. The rate you’re seeing on your router is really quite low, not really something to be excessively worried about until those numbers go up into the tens or hundreds of packets per second.

"To know me is to fly with me."
From: observium [mailto:observium-bounces@observium.org] On Behalf Of Richard Müller Sent: Wednesday, April 06, 2016 1:02 PM To: observium@observium.org Subject: [Observium] Question Regarding CISCO and TX Discards
Hy Observium Community
I have a router, which is only accessible via SNMP from my company, and it shows up some TX-Discards
Just look on this picture:
Unfortunately the company who is administering the Router tells me that they do not see any error.
I really do not have a clue which kind of Tx Discards these are and how they can be shown in CLI.
Does anybody have a clue which “show” Command I have to tell the guy from the ISP that he is seeing these
kinds of errors, also.
It is a CISCO2911/K9 and it is a Gigabit Ethernet Interface.
Thanks in advance.
Richard
