[j-nsp] SRX CoS Bandwidth
Hi, Can anybody explain the QoS operation of a SRX when a higher priority queue is in negative credit and a lower priority queue is in positive credit yet has traffic to transmit? The documentation suggests: "Transmission Scheduling The packets in a queue are transmitted based on their transmission priority, transmit rate, and the available bandwidth. By default, each queue can exceed the assigned bandwidth if additional bandwidth is available from other queues. When a forwarding class does not fully use the allocated transmission bandwidth, the remaining bandwidth can be used by other forwarding classes if they receive a larger amount of offered load than the bandwidth allocated." Yet we have observed starvation of lower priority queues in preference to higher (not strict-high). This appears to be at odds with say the MX or J-series routers mode of operation. Thanks for your help, Tim. ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
Re: [j-nsp] SRX for MPLS
Interesting/ disappointing to read that the top end SRXs don't support MPLS as it is clearly the intention to deploy MPLS to the edge with the smaller SRXs. So what is Juniper's solution for concentration points in the network e.g. head offices etc? Do the large SRXs have no support for "Family mpls" in any fashion? Is it on the roadmap (the statement below would suggest it is)? And if so when can it be expected?

The top end SRX don't yet support the MPLS feature as yet.

Re: [j-nsp] Load balacing issue - M7i
It may depend on the environment you are trying to perform load sharing
in, but we were informed by J-TAC that the M7i CFEB could not perform
MPLS loadsharing across 2 equal cost paths - I'd love to be proved wrong
;-) An Enhanced CFEB would be required :(
May be worth checking with J-TAC for your particular case.
Cheers,
Tim.

Re: [j-nsp] Path MTU Discovery - MPLS VPN
Thanks Masood, I have an FE associated with the VRF on the CE/PE router with a /26 assigned and so I assume I meet that requirement? Should path MTU check work within the MPLS cloud ie. Say a link from the P to PE has a reduced MTU? IS there any general info out there that would help? I had a look at the RFC.

[j-nsp] Path MTU Discovery - MPLS VPN
Hi, I've been trying to get Path MTU Discovery working for M/J-series, appreciate that the M-series requires vrf-mtu-check setting.

[j-nsp] MPLS/VPN PE RPM Probes
Hi, Has any body experience of setting up RPM probes between MPLS/VPN PEs whilst using AS PIC for time stamping and CoS? I've tried to put the SP interface into the VPN without success, hence the return route is unknown to the far end. Using M-series on 8.1 code, it doesn't look like I can change probe source address when using the SP :-( Any other ideas?

[j-nsp] Police Averaging Interval
Hi, Just wondering in any body knows what the time interval is, over which the policer statement calculates the Bandwidth, similarly the period for the burst size? Been digging around the documents and there are a couple of methods which describe how to set burst size... Any decent references?
