Custom Queuing - Byte-Count vs Packet Limit in a Queue

Good morning all. I hope everyone is very well.

I have just configured the below, and it shows that I can have, both byte-count, and a packet-count for Queue 5.

What takes precedence for the scheduler to move onto the next queue?

Kind regards,

Ken

You can define either or both of byte count or packet count to define a threshold for custom queuing at which it should move on to the next queue. It is my understanding that when you have both byte count and packet count configured the first one to get satisfied will cause it to move on to the next queue.

If you do not define which queue is the default custom queuing will treat queue 1 as the default.

Re: Custom Queuing - Byte-Count vs Packet Limit in a Queue

Also, What happens if you do not speficify a default queue within custom queueing?

Priority queueing just whackes it in the normal queue does it not? Custom queuing? just a thought :)

Below I remove it.

Dual3#sh queueing custom

Current custom queue configuration:

List Queue Args

11 5 default

11 1 protocol ip list 15

11 2 protocol ip tcp port 8080

11 3 protocol ip udp port netbios-dgm

11 4 protocol ip tcp port telnet

11 1 byte-count 5000

11 2 byte-count 1250

11 4 byte-count 4000

11 5 byte-count 2000 limit 40
