Prioitise traffic on Cisco 877 and 1841 ADSL VPN routers?

whiteford · ‎11-09-2007

Hi, not sure if this is possible, but the 877 and 1841 ADSL routers I use in VPN mode, can I prioitise certain traffic over the VPN? They mostly use Citrix and outlook, I was wondering if these could be top of te list?

If all of your tunnel traffic is not being encrypted, we need to add this statement to match GRE traffic For example:

access-list 122 permit gre any any. This doc along with this statement will guarantee that all tunnel traffic and all encrypted traffic will have bandwidth set aside for it. You can check to make sure that this traffic is being matched with the following command:

show policy-map interface

Another thing to remember, QoS is on a hop-by-hop basis. Meaning that just because we set aside bandwidth out of this router, it does not mean that these packets are guaranteed any bandwidth at hops along the path.
