Hi,
Can someone explain what could be causing these input errors
WS-C4503 to CBS3020
Cable did test good and re punch connection today
thanks,
GigabitEthernet2/3 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet Port, address is 001e.7ad7.81d2 (bia 001e.7ad7.81d2)
Description: To Blade CBS3020
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
reliability 255/255, txload 4/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 1000Mb/s, link type is auto, media type is 10/100/1000-TX

I just found my input errors are cause by Rx-No-Pkt-Buff. I will move the port to a different group and see if this resolved the issue

Hi,
Can you hardcode the interface to Gig with full duplex on both sides of the connection?
Then clear counters and test again.

That does not help for lack of buffer errors, as the OP stated.

Hi,
can you show the output by the command「show int g2/3 count err」

For thos interested
I was able to match the input errors with Rx-No-Pkt-Buff with the show interface gig 2/3 and the sh int gig 2/3 counters detail. This is when I found out the module was oversubscribe 8:1
Table 5-7 Oversubscribed Port Groupings for Module WS-X4424-GB-RJ45 | |||||
1, 2, 3, 4 | 5, 6, 7, 8 | 9, 10, 11, 12 | 13, 14, 15, 16 | 17, 18, 19, 20 | 21, 22, 23, 24 |
Can someone explain how to calculate 2:1 ratio actullay it is for this module
WS-X4648-RJ45V+E
Thanks
Serge
