We recently install a new clear channel DS3 and have installed an NM-1T# card and everything seems to be okay but I have noticed that some of our ping response times have increased. I have been looking at the dsu bandwidth on some of the sub-interaces and it is saying that the bandwidth is the full 45 meg ds3. I do have traffic-shape commands on each subinterface so that the actual bandwidth to each site is 768000. My question is, do I need to put dsu bandwidth commands in each subinterface so the bandwidth shows the correct bandwidth for each subinterface when I do a sho int command.
Example of the sho int command
Serial1/0.102 is up, line protocol is up
Hardware is DSXPNM Serial
Description: connected to xxxxxxxx
Interface is unnumbered. Using address of FastEthernet0/1 (192.168.xx.xxx)
I will do that. I have also noticed a difference in the MTU size and DLY usec between us and the site. The site MTU size is 1500 and my MTU size is 4470. The DLY at the site is 20000 and here it is 200 usec. Could this cause a significant increase in the response time? Thanks for your help
If the far (remote) side's physical link is T-1, you might try increasing your shaper to permit 1.5 Mbps. (Depending where the frame circuits are, often you won't see much of an issue going beyond CIR.)
What does the far (remote) side do with regard to QoS?
You might be able to monitor your shapers using a "show traffic-shape que". See if they are queuing traffic when you notice ping times increase.
Do the far (remote) sides terminate more than one PVC per site?
You might also need to tune your other traffic-shape values. When ping times increase, do they stay high or do they vary between high and low?
You shouldn't need to place dsu bandwidth statements within each subinterface, although an ordinary bandwidth statement can be useful for other higher protocols.
Is the DS-3 oversubscribed? I.e. do the sum of the PVC exceed its total bandwidth? If they can, its possible congestion is on the physical interface and not the PVCs.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
