Re: Layer 2-7 Switch Module for IBM eServe BladeCenter config

Nice Idea, but that would only work if the port communications are on independent processes and don't need to go to the same server.  I'm going to check that further and the newest firmware had a "service SIP" with could help with lowering the port numbers.

To get around the 8 ports limitation on the VIP you need can create
another VIRT with the same IP and a different virtual server number and
add the remaining 4. HTH.

	BladeCenter config problem

We are setting up a new office Communicator in our network and it
requires a SLB for the Enterprise pool.

I was thinkin of yousing an old "Layer 2-7 Switch Module for IBM eServer
BladeCenter" witch I replaced a year back on or primary webcluster.

The problem I am haveing with the config is that the Enterprise pool
requires 12 ports but the SLB only allows for 8.

I was intending to do a non port loadbalancing but I am haveing prolems
configuring the box for that.

*************************************

The ports I need are:

TCP 5060, TCP 5061, TCP 5065, TCP 5069, TCP 5071, TCP 5072, TCP 5073,
TCP 5074, TCP 8404, TCP 135, TCP 443 and TCP 444.

*************************************

Now the current config I have is:

/c/l3/if 1
        ena
        addr 10.1.2.200
        mask 255.255.255.0
        broad 10.1.2.255
/c/l3/gw 1
        ena
        addr 10.1.2.254
/c/slb/adv
        mnet 10.1.2.0
        mmask 255.255.255.0
/c/slb/real 1
        ena
        rip 10.1.2.41
        weight 10
/c/slb/real 2
        ena
        rip 10.1.2.42
        weight 10
/c/slb/group 1
        health icmp
        add 1
        add 2
/c/slb/port INT8
        server ena
/c/slb/port INT9
        server ena
/c/slb/port EXT1
        client ena
        server ena
        intersw ena
/c/slb/virt 1
        ena
        vip 10.1.2.50
        layr3 ena
/c/slb/virt 1/service 5060
        group 1
        pbind clientip
/c/slb/filt 1
        ena
        action allow
        vlan any
/c/slb/port EXT1
        filt ena
        add 1

*************************************

The problem I cant seem to get past is that even if I do "layr3 ena" I
still have to assign the "group 1" inside a virt 1/service (5060).  I
have confirme the SLB is functioning on the specified port 5060.

Is there any way to do this without ports?, Just a straigt IP
loadbalancing without any ports assigned?

I  know my firmware is old (20.2.2.7) and fully intend to update it but
first I like to know if this is possible.
