half duplex or full duplex configuration for MDS9124 management port?

[dennis.dai]

Hi All,

Is it possible to set the management port of mds 9124 about half or full duplex configuration?

I want to correct following error:

Jun 13 10:27:20.799 GMT: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on GigabitEthernet4/18 (not half duplex), with mtw1pc02bs0(FOX1450G8QG) mgmt0 (half duplex).

it seems mds 9124 set his port to half duplex.

You may want to check this thread :

Else try the following :

switch# config terminal

switch(config)#

switch(config)# interface mgmt0

switch(config-if)# switchport duplex full

switch(config)# exit

switch#

switch# copy running-config startup-config

Also, I would suggest you check what the counterpart of your MDS switch mgmt interface is set to (i.e. is it set to autoneg, then try setting it to fix speed/duplex or the other way around).

Hi Dennis,

You might have hit bug CSCte76880 (http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCte76880)

Configure both interfaces to auto duplex achieve a full duplex connection as a workaround, or upgrade to 4.2(7e) or 5.0(4d) where the fix has been integrated.

Best Regards,

Hi Dennis,

is there a reason you're not using auto detect?

Hi Kris,
