Cisco Catalyst 6500 GVRP

Trying to enable GVRP on a Cisco 6500.  Cisco docs say just type "set gvrp enable".  "set" is not a command available.  Also, it says to run this command from "Console> (enable)" mode.  As far as I can tell this is not the same as "Router#" mode.  Any help would be appreciated.   Here are the module and software versions:

GVRP is a Layer2 protocol so you probably need to be in the switch part of the box and not the router mode.  You should be able to type "enable" to get to that level.
hbrumfieldAuthor Commented:
Not sure what you mean.  When I login (either telnet or console), the prompt says Router>
Then I type enable, enter enable password and the prompt changes to Router#

Thanks in advance for help.
I was thinking this worked like all the other L2/3 switches I have used that have a command level for switch commands and another, with the router prompt, for router commands. It looks like Catalysts with IOS don't use the set and clear commands like the CatOS. They might not support GVRP either.

Do you know of it is possible to boot the Cat 6500 from either the cisco IOS or CatOS?

Don JohnstonInstructorCommented:
GVRP is only available on 6500s if they're running CatOS. Your switch is running IOS so you can't run GVRP.

Since CatOS is being depreciated (nice way of saying abandoned), I wouldn't change your operating system just to get GVRP.

Thanks for the info.  Basically I am trying to get a Dell Powerconnect 6248 trunk port to work with our Cisco 6500.  I found this posting below which led me to think that I needed to enable GVRP.  Any thoughts?

Don JohnstonInstructorCommented:
GVRP is designed to automatically remove unneeded VLANs from trunks.

What is the config for the 6500 port going to the Dell?

Should be something along the lines of:

int g3/5
 switchport trunk encap dot1q
 switchport mode trunk

You should be able to easily configure both switches to tag the common connection for the VLANs you want shared between them.

Thanks for the help.  I will try it tonight or tomorrow and let you know if it works.
u need to been privilaged mode.

router> (enable mode)
router#   <<<<<<<<<<<<<<<<<<<<<< u need to be in here to make any changes.
router(config)# configuration mode

Please follow this doc is for GVRP for IOS
hbrumfieldAuthor Commented:
Unfortunately, the 6500 is running IOS, not CatOS which is required to use GVRP.  Following "donjohnson's" commands allowed the Dell to talk to the cisco.
