setup with 2 CSM

olesvanherman — Thu, 22 Sep 2005 16:05:08 GMT

Hi,

I have 2 x (cisco 6509/sup720/CSM).

I try to setup vlan with FT setup:

r1:

module ContentSwitchingModule 7

ft group 1 vlan 9

priority 30

preempt

vlan A server

ip address 10.0.99.2 255.255.0.0

r2:

module ContentSwitchingModule 7

ft group 1 vlan 9

priority 20

preempt

vlan A server

ip address 10.0.99.3 255.255.0.0

When I reboot module 7 on r1, I see right

logs (so I believe FT works).

Now the problem:

I need to give a default gateway for

my vlan A (network 10.0.0.0/16).

I would like to use 10.0.99.1 for gateway.

So:

r1#conf t

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

r1(config)#mod csm 7

r1(config-module-csm)# vlan A server

r1(config-slb-vlan-server)#alias 10.0.99.1 255.255.0.0

it pings. great. I reboot csm on r1,

10.0.99.1 doesn't ping. it's normal since

I setup nothing on r2.

But what have I add on r2 ?

I can't add this:

r2#conf t

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

r2(config)#mod csm 7

r2(config-module-csm)# vlan A server

r2(config-slb-vlan-server)#alias 10.0.99.1 255.255.0.0

If I add it, I have arpwatch alerte because

r1 fights with r2 for 10.0.99.1.

I have no idea how can I have a high

availbility gateway.

Thanks for help

PS. there is lot of mistakes in your docs 2.1 from 2002:

1.)

conf t

mod csm 7

vlan 9 ft

(there is not possibility to setup ft, only

client and server).

2.) you propose to setup interface vlan 136

in csm module. It isn't possible.

3.) alias ip addr A.A.A.A doesn't exist.

alias A.A.A.A exists

4.) etc etc.

could you get a 'sho mod csm x ft' and a 'sho mod csm x ft detail' on both r1 and r2 when r2 is supposed to be active and post the info to this forum.

Thanks,

Gilles.

Hi Gilles,

The problem is resolved. Vlan 9 didn't work

well and 2 FT were actived.

Thanks

you need to configure the units so they act together as alternates for each other. On r1 you would have the following config:

module ContentSwitchingModule 7

ft group 1 vlan 9

priority 30 alt 20

preempt

vlan A server

ip address 10.0.99.2 255.255.0.0 alt 10.0.99.3 255.255.0.0

alias 10.0.99.1

On R2 you just need the following:

module ContentSwitchingModule 7

ft group 1 vlan 9

priority 20 alt 30

preempt

then on R1 issue the following command:

hw-module csm 7 standby config-sync

This will sync the configs and then if you issue the following command on each you should see mirror images of them.

show run mod 7
