hold queue in and out

[Tshi M]

I am looking at a private line DS3 configuration and I notice that the serial interface is set as follows:

interface Serial1/0

ip address 10.1.1.1 255.255.255.252

encapsulation ppp

dsu bandwidth 44210

hold-queue 800 in

hold-queue 800 out

why would one decide to use hold-queue on a dedicated circuit?

To deal with traffic burst, so that the router will queue packets rather than dropping them.

800 for a DS3 seems reasonable, you can observe how much of that has been used, if ever, with "show interface".

Hope this helps, please rate post if it does!
