| yes it does support mls with 32 10/100 MB and 2 GBIC ports check the name on cisco site | |
|
| Thanks,haseeb_eng.But I don't know how to configure it,and I don't know where is the Cisco's paper.Could you give a URL here? | |
|
| hmmmmm
not sure if haseeb is referring to the layer3 module.
Features
The Catalyst 4000 Layer 3 Services module provides multiprotocol switching and routing for the Catalyst 4000 family switches.
The 32 10/100 Ethernet interfaces on the module provide full Layer 2 feature support and are configurable from the Catalyst 4000 family switch supervisor engine.
however, note that later on it state
Unsupported Features
The following major features are not supported on the Catalyst 4000 Layer 3 Services module:
Multilayer Switching (MLS)

it is the first link on the search result for *4006 mls* @ cisco | |

| Maybe I didn't make it clear.It is Cisco 4006 with Supervisor Engine III. | |

| The 4006 does not support proper MLS, meaning that it doesn't make layer 3 forwarding in hardware like the 5xxx or 6xxx series. It does, however, support layer three routing in the chassis through a couple of facilities.
With the SupII, you can use the Layer 3 services modules (a seperate line card) that haseeb mentioned. The L3 engine has two logical gig ports to the sup engine. create an etherchannel with these (careful which ports you choose, because it's not logical) and trunk all your VLANs up the channel. Create sub-interfaces on your port channel, assign your VLANs and IP addresses to the subs and route away.
The new SupIII is IOS based and features L3 services in the supervisor. Configuring it is pretty much like configuring L3 on the 3550s or a MSFC or RSM. (But it's not MLS). You just create vlan interfaces and assign your L3 properties there. The cool thing about the SupIII is that all your switching and routing configuration is done at the same place.
Hope this helps.

You posted the module type while I was responding. Take a look at the documentation for the code for the SupIII:

| Hasseb_eng,
This is what the my first link says:
""Multilayer Switching and NetFlow Data Export
Multilayer Switching (MLS) scales Layer 3 performance to high-performance link speeds by extending the MLS concept introduced in Cisco IOS software to LAN switching hardware. MLS requires a Catalyst 5000 family switch with a Supervisor Engine III and NetFlow Feature Card (NFFC) or NFFC II. NetFlow Data Export allows you to export MLS flow information to an RMON probe for analysis.
There are three MLS feature sets supported:
IP unicast MLS
IP multicast MLS
IPX unicast MLS""
This is why I wrote it appears the 4000 doesn't support it. If anybody has found something contrary to this, please post it and we'll all discuss it. | |

| I also found this document
http://www.cisco.com/univercd/cc/td...tm#xtocid642913
This document entitled "Configuring IP Multilayer Switching" has a section "Software and Hardware Requirement" which lists the different kind of switches that could be used but the Catalyst 4000 series is not listed. | |

| As you have noticed the 4006 doesn't support the 5000 - 6000 - 8000 vlan configuration. You need to define your vlans with a Port-channel 1.x .
As with most sub-interfaces information in the parent is rather slim. So configuring Port-channel 1 is best not done.
==============================
==========
G1 and G2 are the on-board external GB uplinks. Internally there is a G3 and G4 which communicates to the switch module. I have installed 7 of these devices without a hiccup using this configuration. There may be a better design... Currently I have upto 23 Port-channels defined .
You may have also noted that the 4006 does not support ISL, this product was not Cisco developed. I have NOT had the opportunity to config the newer Sup III. This config may not be valid with the Sup III.

| We can use any external device for mls ? | |

| Please try the following link
MLS -
http://www.cisco.com/cgi-bin/Suppor...layer_Switching
MLS - System Requirements
http://www.cisco.com/cgi-bin/Suppor...em_Requirements
Bookmark these and use them as a starting off point.
Note: as good / wonderful as Cisco's documentation is, they always cannot keep up with harware or software upgrades in all of their documentation.
A lot of experimentation in your lab is the best way to test out configurations. Try MLS with a set of known compatible devices. Once you have that down pat, move those configs to your other devices, making what ever changes are needed. If it works, great; but you better check it under stress before production.
You could also check with TAC to validate your configuration. This way you won't have a career ender. | |

| Hi,thanks everyone! I checked the cisco's configure paper and found layer 3 switching in C4006-s3 is called CEF,and it is default enabled.we need no commands to configure it. |
