It is Private frame-relay circuit.
yes. the cir is 512 kbps on remote site as well.
No. the host site has only one pvc which is to the branch office. so to
speak you can say the total pipe is 512 kbps.
The ISP is doing best effort. No QOS from ISP.
The traffic shapping is as follows:
map-class frame-relay shape
frame-relay cir 512000
frame-relay bc 2560
frame-relay be 0
frame-relay mincir 512000
no frame-relay adaptive-shaping
frame-relay fair-queue
frame-relay voice bandwidth 128000
frame-relay fragment 120
access-list 101 permit udp any any range 16384 32767
the bandwidth = 512kbps
This 512 kbps is (incoming + outgoing). One way (i.e incoming ) it is
256kbps. is this right assumption or is there a error in my judgement.
thx,
sam.
