Just looking to bounce this off anyone in the know.
As I learn more about Juniper CoS in Junos, it appears to me that a Juniper device comes by default acting as a Behavior Aggregate classifier on each interface that has an ip address enabled. I'm saying this since I have IP's on 3 interfaces, and I'm seeing Junos assign a default classifier to each of those logical units. I'm saying BA since I understand a BA classifier is one assigned using class-of-service classifier like I see here. and not the other type MFC (multi-field classifier) which uses a firewall filter I'm wondering if the BA classifier stops working once an MFC is applied. It sure seems to in testing. I feel like I've seen a diagram at some point or document stating that MFC comes before BA in the CoS process chain. but I'm not sure. If anyone has that link/doc please send it. I'd like to know for sure. Oh, btw, were in the world is all this default CoS stuff derived from? I'd like to think it's in a file somewhere that I can see in shell perhaps. But maybe not. Maybe it's actually compiled into the Junos operating systems itself. Or is there a way to see "show configuration" with a special option that shows automatic/default stuff like all this CoS info? The available default classifiers. root@srx-1> show class-of-service classifier | grep classifier Classifier: dscp-default, Code point type: dscp, Index: 7 Classifier: dscp-ipv6-default, Code point type: dscp-ipv6, Index: 8 Classifier: dscp-ipv6-compatibility, Code point type: dscp-ipv6, Index: 9 Classifier: exp-default, Code point type: exp, Index: 10 Classifier: ieee8021p-default, Code point type: ieee-802.1, Index: 11 Classifier: ipprec-default, Code point type: inet-precedence, Index: 12 Classifier: ipprec-compatibility, Code point type: inet-precedence, Index: 13 Classifier: ieee8021ad-default, Code point type: ieee-802.1ad, Index: 41 The ipprec-compatibility classifier I find assigned to enabled interfaces. root@srx-1> show class-of-service interface | grep "object|classifier|logical" Logical interface: ge-0/0/0.0, Index: 74 Object Name Type Index Classifier ipprec-compatibility ip 13 Logical interface: ge-0/0/1.0, Index: 75 Object Name Type Index Classifier ipprec-compatibility ip 13 Logical interface: irb.0, Index: 73 Object Name Type Index Classifier ipprec-compatibility ip 13 Details of the classifier I see assigned to my enabled interfaces. root@srx-1> show class-of-service classifier name ipprec-compatibility Classifier: ipprec-compatibility, Code point type: inet-precedence, Index: 13 Code point Forwarding class Loss priority 000 best-effort low 001 best-effort high 010 best-effort low 011 best-effort high 100 best-effort low 101 best-effort high 110 network-control low 111 network-control high (no user defined cos config is present) root@srx-1> show configuration class-of-service | display set root@srx-1> Aaron aar...@gvtc.com _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
