ISDN PPP Multilink dialer load threshold

hallo

I have a main office with a cisco 2600 router connected to BRI interfaces.

Remote offices use cisco761 router to connect to main office cisco 2600.

The main office router must only respond to remote calls.

I need bandwidth on demand so when the load on a B channel passes a threshold a second B channel will be used.

* This is part of the cisco2600 config

!

interface BRI1/0

description 'connected to Bassano -Set'

no ip address

no ip directed-broadcast

encapsulation ppp

dialer pool-member 1

isdn switch-type basic-net3

isdn send-alerting

no cdp enable

ppp authentication chap

ppp multilink

!

interface Dialer1

description 'connected to Bassano'

ip address 192.168.101.1 255.255.255.0

no ip directed-broadcast

encapsulation ppp

dialer remote-name bassano761

dialer pool 1

dialer idle-timeout 300

dialer hold-queue 20

dialer-group 10

bandwidth ?

dialer load-threshold ?

dialer load-interval 30

set system bassano761

set switch net3

demand 1 threshold=0 duration=1 source=lan

demand 2 threshold=48 duration=1 source=both

timeout 1 threshold=0 duration=500 source=lan

timeout 2 threshold=48 duration=300 source=both

WHICH ARE THE VALUES FOR THE FOLLOWING PARAMETERS IF I WHANT THAT THE SECOND B CHANNEL GOES UP WHEN THE FIRST REACHES 60Kbps ?

bandwidth ?

dialer load-threshold ?

demand 2 threshold= ? duration=1 source=both

timeout 2 threshold= ? duration=300 source=both

THANKs

Re: ISDN PPP Multilink dialer load threshold

For 60% load, your threshold should be set to 255 * 0.6 = 1531. I dont think you need to set bandwidth as well.

Thanks.

Re: ISDN PPP Multilink dialer load threshold

You need to enter following command if you want the first link loaded to (threshold=60) 60kbps for continuously 300 secs (duration=300) before 2nd b channel will be dialed.

demand 2 threshold=60 duration=300 source=both

Here is the link which explains how to use that command and what are thoes parameters means.

Re: ISDN PPP Multilink dialer load threshold

Ok for the cisco760 but for cisco2600 dialer interface what are the values for:

- bandwidth

- dialer load-threshold

Can I use "bandwidth 128" and "dialer load-threshold 120" (60*255/128) ?
