AW: [j-nsp] queueing on juniper interface (dscp classifier)

Wed May 19 04:16:45 EDT 2004

Assuming that you deploy eFPCs on your system, class resp. queue counters
can be viewed by "show interface fe-0/1/0 extensive". If you use standard
FPCs no counters are maintained. By "show chassis hardware" you can check
whether you have standard or eFPCs.

Betreff: [j-nsp] queueing on juniper interface (dscp classifier)

Hi
How can I check the queueing or check if the classification (classifier
inet-precedence VIDEO) is used on the router interface:

cisco-----------------------juniper----------------cisco

class-of-service { 
classifiers { 
inet-precedence VIDEO { 
forwarding-class assured-forwarding { 
loss-priority high code-Ponys af21; 
} 
}

on the cisco it's show policy-map interface and the dscp af21 is used !!!
Thx 
Charly
