Re: Multilayer Switching [7:24595]
I am now very confused. On the 6509, if I put show mls rp, it said MLSs was globally disable. When I turned on MLS on both global and interface mode (include vlans that have NAT), it took just fine. Now I issued show mls rp interfaces, VLANs with NAT didn't appear on the list of interfaces enabled for MLS, though those VLANs took the command without error. On Cisco documentation, it says the above set of commands are only for CAT 5000 platform; and that MLS will be automatically disable on VLANs running NAT. It also says that MLS is enabled by default on 6509s. Issuing a command show mls status on 6509 MSFC will show the output below. However, if you do a ? browsing after show mls, you won't see a subcommand status. But if you just type the whole command show mls status, it doesn't give any error, but yield the output below: MLS global configuration status: global mls ip: enabled global mls ipx:enabled global mls ip multicast: enabled current ip flowmask for unicast: destination only current ipx flowmask for unicast: destination only According to this, I assume 6509 has both MSFC and sup. engines enlabled for MLS, but I am not sure if VLANs with NAT still running MLS... How should I check it? What about Multicast MLS for NATed VLANs? Thomas N. MADMAN wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

You can go to the switch prompt to check MLS by using the command . There are other options with this command. Thomas wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Multilayer Switching [7:24595]
IF you have that vlan off then the ip nat inside statement is useless I would assume. If infact the ip nat inside statement is doign something, I would assume the vlan to be on...

Re: Multilayer Switching [7:24595]
Sorry all for the confusion. I mean I could not enable MLS on VLANs that are running NAT. When I put mls rp ip on VLAN interfaces that have NAT running, I didn't get any error message. However, when I did the show mls rp interfaces I didn't see VLANs with NAT on the list of VLANs running MLS. Patrick Ramsey wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Multilayer Switching [7:24595]
If the nat cause the problem (although I doubt it), perhaps you can try by shutting the nat of after clearing all cache entries before hand ? use the clear ip nat trans * command to do that, or you can also specify certain host if you like. One fenomena that I heard in 6500, is that when you define a vlan and there is nothing on physically at that VLAN (no physical machine connected), the vlan interface is regarded as off. I don't know if this is true or not, but that's what I've heard.
