Please post the switchport config from the 3750.

Which vlan is the controller's management address on?
On the controller, is the management interface configured as tagged or untagged?
Best practice is to specify a native vlan on the Catalyst's switchport, and leave the management interface untagged.
05-07-2009 09:37 AM
The management interface is untaged an is on vlan 1 which is the default vlan of the switch.
05-07-2009 09:53 AM
back to gam's response..
Under the controller-->interfaces-->managment interface-->Vlan Identifer
What do you have in the VLAN Identifer "0" or "1" ?
Normally when you cant access the managment interface its 90% of teh time a tag issue. At least that has always been what i seen ...

pls check the new config of both devices

I never used VLAN 1 on the controllers. Ive always used "other non-vlan 1" VLANs and the native statements.
Try this ... move the switch port to access and see if you can hit the controller. If you can you know you have a miss match.
Although you shouldnt have to use the native stament for VLAN1 but you can also try adding that and see if you can hit it ...
Also put something else on the switch and see if you can hit that device ...
btw... are you plugged into port 1 on the controller to your switch... thats what you have the man interface pointing at !?

Am using untagged vlan on the controller which is vlan 0 by default.i have use it as an access it does not hit it....
But thanks so much i have got it i used the management port on the trunk and u see it ping the switch verse versa
05-07-2009 12:20 PM
come again? you used the managment port on the trunk?
05-07-2009 11:40 PM
Yes. I used the managemen port which is port 1 and i connected it to the trunk port of the switch which is port f1/0/24 on the switch.I used a cross over Cable.
