IPX MLS

[cadams]

I am trying to disable mls IPX on a switch. The config file reads" set mls ipx enable" How do I disable it? Is it enabled by default?

[Prashanth Krishnappa]

What switch is it? If it's an CAT6000 with an MSFC in it, you'll need to do the following on the MSFC

MSFC15(config)#no mls ipx

BTW why do you want to disable MLS?

It's not that I want to disable MLS IP only IPX since we are no longer running that protocol.

Thank you for you help!

This did not solve my problem.

On the catalyst switch, did you enter "set mls disable ipx"

eg.

Console> (enable) set mls disable ipx

IPX Multilayer switching is disabled

Console> (enable)

I entered the information you gave me and this is what I got:

bldg3-c6500-1> (enable) set mls disable ipx

Unknown command "set mls disable". Use 'set mls help' for more info.

bldg3-c6500-1> (enable) set mls help

Set mls commands:

It does not seem to be working. I am using Cat OS Sw : 5.5(4b)

According to this link Catalyst 6000 family supervisor engine software version 5.2(1) CSX or later supports IPX MLS:

The CSX leads me to believe you can't enable ipx mls on your switch.

This is what I was refering to in my last post:

If you do a show mls ipx on your switch does it show it's enabled? How about any candidate packets?

If no, I don't think it's enabled.

Steve,

This is the info from the switch with a show mls:

bldg3-c6500-1> (enable) sh mls ipx

IPX Multilayer switching aging time = 256 seconds

IPX flow mask is Destination flow

IPX max hop is 255

Active IPX MLS entries = 0

IPX MSFC ID Module XTAG MAC Vlans

--------------- ------ ---- ----------------- ----------------

192.168.8.252 15 1 - -

bldg3-c6500-1> (enable)

I would like to disable this.

Dont worry about the above output. Once you disabled IPX MLS on the MSFC you have disabled it. If you observer the above output, you do not see a MAC address for the router. With IPX mls is enabled, here is what you would see

cs-c6009-22a> (enable) sh mls ipx

IPX Multilayer switching aging time = 256 seconds

IPX flow mask is Destination flow

IPX max hop is 255

Active IPX MLS entries = 0

I dont think you can disable it on the Supervisor side. There was a development bug filed to remove this line from Non-default configuration. Try upgrading to latest GD 5.5(16) and you should not see it. I tried the following in the lab MSFC here

Router#sh mls status

MLS global configuration status:

global mls ip: enabled

global mls ipx: enabled <<<<<------------

global mls ip multicast: disabled

current ip flowmask for unicast: destination only

current ipx flowmask for unicast: destination only

Router#conf terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#no mls ipx

Router(config)#end

Router#

Router#sh mls status

MLS global configuration status:

global mls ip: enabled

global mls ipx: disabled<<<<<------------

global mls ip multicast: disabled

current ipx flowmask for unicast: destination only
