My server reported event 1123. It seems to relate to switch. Need to know how to set more detail logging for the switch to see if there is any packets loss

Hi,


Look at the interface stats on the switch for the server ports,

Show interface fa0/1

FastEthernet0 is up, line protocol is up

Hardware is Lance, address is 0060.3ef1.702b (bia 0060.3ef1.702b)

.....

115331 packets input, 27282407 bytes, 0 no buffer

Received 93567 broadcasts, 0 runts, 0 giants, 0 throttles

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

0 input packets with dribble condition detected

143782 packets output, 14482169 bytes, 0 underruns

0 output errors, 1 collisions, 5 interface resets

0 babbles, 0 late collision, 7 deferred

0 lost carrier, 0 no carrier


perhaps you have a routing issue, or perhaps you have errors on

your switch ports, bad cable etc ....... need more information on your setup.


You can monitor a port on a switch via a span session:

You can use various debug commands; see here http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_25_sea/command/reference/debug.html


HTH - Please rate if it does.
