Hello, The FC in JUNOS is the same as qos-group in CSCO IOS - invisible internal-only field which travels along with packet content across the switch, but is never inserted in the actual packet. The FC has significance for choosing output scheduling, RED drop, marking. Of course there are

Hi Dan, Seems odd to me that this needs to be done. Documentation I've read appears to suggest that in PIR mode (no guaranteed-rate set) the per-queue guarantee/transmit rate is calculated from the shaper rate and when a queue exceeds it's guaranteed rate it is in excess, but this doesn't

That comment does not directly state it's in fabric side, the implication can be made, but it's not true. There is no external PHY, it's exactly like 4x10GE MIC, hence it must connect on WAN side. On 25 June 2015 at 19:07, Olivier Benghozi olivier.bengh...@wifirst.fr wrote: Hi Saku, Well,

Alexander, There is one thing (two, actually :-) I cannot understand, please bear with me. Does your fixed port classifier change the way frames are processed in the switch (queue assignment etc) or is this classification purely a marker? After you assign a forwarding-class with the first
