Sorry Mate, but you'll have to provide more information than this.

Just want to give you some info that my parole officer and my "shrink" has taken away my "mind-reading" pills after they received numerous complaints from the not-so-intelligent-intellligence community.

i  Create vlan 10   DHCP scope for the service port of the  Cisco WiSM in Supervisor 720 ( wism 1 installed in first switch6509)

and create vlan 20 for wism 1 managment and AP managment .

i need ask these two vlan created to wism 1 for first switch6509 itself can be used

  the same in wism 2 in second 6509 or it must  create new two vlan id  for wism 2 installed in second swich6509

note two switches 6509 connected by vss technology.

please advice .

You've created a DHCP scope for VLAN 10 (service port) and VLAN 20 (management and AP-manager IP address) for one WiSM and you want to know if this will work with a second WiSM on a 2nd chassis of a VSS?

On paper, it will work.  In practice, WHY?  Why do a DHCP in the first place?  I know it's fairly easy to configure a DHCP scope but that adds another process in configuration and maintenance of your WiSM.

Thanks for the ratings.

Hi Mohammad,

  First, VSS redundancy it's completly independent for WiSM redundancy.

  What you can do it's configure both WiSM at same mobility group, so you have a cluster with two controllers. With all APs registered on it, you can share half of your APs at WiSM-A and the other half at WiSM-B, because Primary, Secondary and Terciary controller settings are AP independent, So you have redundancy for you LWAPP wireless network.

  Now, for VSS, you have your L2 and L3 unified at 6500 series switch. This config it's independent of anything, and you'll have to know how you wanna have the L3 of your network, making the virtual interfaces across VSS system.

  You can take a look at this document, just to understand it: http://www.cisco.com/en/US/partner/products/hw/modules/ps2706/products_tech_note09186a0080a6c202.shtml
