Hi All

After deploying WAAS , i.e. WAE-302 module in Cisco 2811 Router on core and edge with default setting and running wccp on the router , network is dead slow .

Core and edge network are connected with dedicated 2MB lease line.

License is Transport.

I can see traffic optimizing on WAE core and Edge but netwrok is dead slow.

Any suggestions.

Regards

What was changed on the routers during this implementation? Only configuring the module, enabling wccp 61/62 and enabling redirection on the LAN/WAN interfaces?


Were additional routes added? Is it possible a routing loop was introduced? Do you see a reasonable number of connections on the WAEs?


I suggest looking at the following to see if any problems are indicated:


On the routers:

show ip wccp - should see most packets redirected via CEF


On the WAEs:

show wccp gre - look for any high counters that don't look right

type-tail syslog.txt 50 - look for messages indicating possible problems



If the network is slow I am assuming routing is OK. What applications specifically are slow?


if you disable WCCP in the WAE, is it still slow?


are the slow applications being optimized.

capture a trace of a transaction between the client and server on the WAE.


tethereal -s 1600 -w edge.dat -R "ip.addr eq x.x.x.x"
