I've been sick the last couple of days and although I've made time to study, I have not devoted time to posting my notes. So here are my latest notes from Narbik's StN workbook, starting with QoS.
- Priority queueing is processed like ACLs - top-down.
- "priority-list x [interface|protocol|default] queue [tcp|udp|acl]" assigns traffic to a queue
- "show queuing priority" shows priority queues
- "priority-list x queue-limit " alters queue sizes
- "custom queuing queue-list x" creates a custom queue much like a priority queue
- With custom queuing, bandwidth is allocated by assigning byte-counts in increments of 1500
- "hold-queue x out"WFQ packet limit for all queues
- To create a rate-limit ACL using IPP, add binary of IPP levels. binary 01 is IPP 0, bianry 10 is IPP 1, so mask if binary 11 or 3.
- "show interface | i Internet" shows all IP addresses (except secondary) with netmasks.
- "sh run | in no\ "shows disabled servers. (note: there is a space after \)
- rsvp must be done per interface along the path.
- test rsvp using "ip rsvp sender-host|reservation-host" from config mode.
- "ip rsvp sender" is used to proxy for another host.
- "ip rsvp reservation" is used to proxy for another reservation host.
- "frame-relay de-list x protocol ip tcp 80" can be used to assign protocols (such as HTTP) the de bit. Can be applied by using "frame-relay de-group x dlci y"
- You can enable "random-detect dscp-based" directly on the interface.
- ECN marks packets instead of dropping them.
Up next...3550/3560 QoS
