Hey folks, I'm sure to you it's peanuts, but I'm a bit puzzled (most likely because of the lack of knowledge, I bet).
I'm buying an IP backbone from VNZ (presumably MPLS). I get a MLPPP hand off on all sites, so I don't do the actual labeling and switching, so I guess for practical purposes what I'm trying to say is that I have no physical control over the other side of my MLPPP links.
When I transfer a large file over FTP (or CIFS, or anything else), I'd expect it to max out either one or both T1, but instead utilization on the T1s is hoovering at 70% on both and sometimes MLPPP link utilization even drops below 50%. What am I'm not gettting here?
I seem to be in a similar situation as you (but with AT&T). I have not noticed any unexpected missing bandwidth. I don't see any specific problems with your config, but I'll include mine in hopes it will be useful: controller T1 0/0/0 framing esf linecode b8zs channel-group 0 timeslots 1-24 ! controller T1 0/0/1 framing esf linecode b8zs channel-group 0 timeslots 1-24 ! class-map match-any imaging match access-group 112 class-map match-any rdp match access-group 113 class-map match-any voice match ip dscp ef match access-group 110 ! policy-map private_wan class voice priority percent 60 set ip dscp ef class rdp bandwidth percent 32 set ip dscp af31 class imaging bandwidth percent 4 set ip dscp af21 class class-default bandwidth percent 4 set ip dscp default ! interface Multilink1 ip address x.x.x.38 255.255.255.252 no keepalive no cdp enable ppp chap hostname xxxxxxx ppp multilink ppp multilink fragment disable ppp multilink group 1 max-reserved-bandwidth 100 service-policy output private_wan ! interface Serial0/0/0:0 no ip address encapsulation ppp no cdp enable ppp chap hostname xxxxxxxxxx ppp multilink ppp multilink group 1 max-reserved-bandwidth 100 ! interface Serial0/0/1:0 no ip address encapsulation ppp no cdp enable ppp chap hostname xxxxxxxxxx ppp multilink ppp multilink group 1 max-reserved-bandwidth 100 ! access-list 110 permit ip any 10.0.0.0 0.0.255.255 access-list 110 permit ip 10.0.0.0 0.0.255.255 any access-list 110 permit icmp any any access-list 112 permit ip any host x.x.x.x access-list 113 permit ip any host x.x.x.x
