multi- and private-vlans


my admin asked me for configuring a multi-vlan on Cat6500 running Native IOS mode. I logged in, typed conf t, int fa4/30, switchport mode ? and what was very strange - I haven't seen a 'multi' clause. I was looking at CCO for some kind of vlan strategies which could have more or less the same functionality as multi-vlan on 29xx/35xx. I looked at private-vlan but I found only few links concerning this subject, i.e.

Could anyone give me any idea which could be worthy to look at (of course in multi/priv-vlans subject) ?

Re: multi- and private-vlans

Only the XL switches support multiVLAN ports. Why do you need this feature on your 6500? Is it to carry multiple VLANs to another switch/server? Check to see if the other switch/server NIC supports some kind of VLAN trunking. You can configure ISL and/or 802.1q trunks on the 6500's to carry multiple VLANs over a single link.

Re: multi- and private-vlans

Certainly, it's for connectiong the EMC appliance. Now it's connected via 3xGE To that switch there are several servers connected.

It is like this:

there are 3 EMC DataMovers connected via GE which are responsible for various services. One of them is a hot-swap mover, which can be used automatically when one of the two data movers will not work due to a failure.

My admin wants the two data movers to be in seperate vlans each, and the hot-swap data mover to be in lans which the first and second movers are.

In 29xx/35xx i would use multi-vlan. In 65xx I donna know what to do with this ugly emc devices :>
