Custom-queue problem

[santipongv]

I have a T3 connection from point A to point B. I have custom-queue configured on Router A on T3 connection but not on Router B. Will this cause packets to drop? Do I need to configure the same custom-queue on both side of the connection?

If you only configure it at one end, that does not mean that the other end will drop those packets. What will happen, though, is that you will not have appropriate prioritisation happening at the other end. However, if the congestion is only present on the router where you have applied custom queueing, the absence of custom queueing at the other end will not be a problem.

Hope that helps - pls do rate the post if it does.

While I feel that best practices for queuing is to have equivalent queuing configured on both ends of the connection, I do agree with Paresh that in certain circumstances where congestion is present only on one end of the connection that queuing configured only on that end is sufficient.
