Hi Scott,
What do you mean by "reserved queues"? WFQ is there too... so... Are you
talking about priority queue by LLQ?
Or what are you referring to?
Thanks in advance,
Best Regards,
Hunt

That's correct. RTP is UDP stuff (primarily voice), while TCP is...
Well... TCP. :)
The queuing isn't very forgiving there. :) No reserved queues, but only 16
dynamic queues?Apparantly not much will happen on this line! But you want
to allow a good amount of RTP through...

Subject: Compression mystery
Hi Group,
I saw the following config from a VoIP config...
Would you know what is the differnece between "ip tcp header-compression
iphc-format" & "ip rtp header-compression iphc-format"?
Is it the first one is used to compress TCP "data" traffic, whereas the
latter one is used to compress "RTP traffic" e.g. voice?
interface Multilink1
ip unnumbered Ethernet1/0
no ip directed-broadcast
ip tcp header-compression iphc-format <--- This?
no ip mroute-cache
fair-queue 64 16 0
no cdp enable
ppp multilink
ppp multilink fragment-delay 10
ppp multilink interleave
multilink-group 1
ip rtp header-compression iphc-format <--- & this?
ip rtp priority 16384 16383 48
And what does iphc-format do?
Any help / ideas would be greatly appreciated.
Regards,
Hunt
