The configuration to support this scenario is similar to
1. Configure the string and assign contracts for the strings and services.
2. If the same string is used by more than one service, and you want to allocate a certain

using the urlcont command.
>> # /cfg/slb/virt 1/service 80/http/urlcont <URL path ID> <BW Contract number>
Note: When assigning
cfg/slb/layer7/lb/cont
even if Contract 2 has higher precedence.
Example Configuring Security Management
BWM can be used to prevent Denial of Service (DoS) attacks that generate a flooding of "necessary
evil" packets. BWM limits the rate of TCP SYN, ping, and other disruptive packets. BWM can alert the
network manager when soft limits are exceeded.
In this example, a filter is configured to match ping packets, and BWM is configured to prevent DoS
attacks by limiting the bandwidth policy rate of those packets:
1. Configure Alteon as usual for SLB (see
— Assign an IP address to each of the real servers in the server pool.
— Define an IP interface on Alteon.
