Multilink Performance Question

[thessick]

We have a remote site connected with four T1's in a multilink bundle. All four circuits are a bundle member and are showing no errors.

interface Multilink1

ip address 170.x.x.x.255.255.252

ppp multilink

ppp multilink group 1

.

.

.

interface Serial0/0

description NorthHills T1 #2

no ip address

encapsulation ppp

keepalive 10 3

no fair-queue

ppp multilink

ppp multilink group 1

Using Qcheck, the best performance I can get is 3Mbps. I would expect somewhere between 3 and 6.

Locally we see 90Mbps between stations.

Performance expectations?

Tuning suggestions?

Diagnostics?

Thank You

I suggest taking apart one of the T1s out of the bundle with different IP addres scheme (another x.x.x.x 255.255.255.252) and try to stress it out and watch counters and errors, repeating for each single T1. A quick status is shown using the following command:

show ppp multilink

Hope this helps,
