Combinations

Combinations of classifications are limited to grouping items together into a contract. For
example, if you wanted to have three different virtual servers associated with a contract, you
would specify the same contract index on each of the three virtual server IP addresses. You can
also combine filters in this manner.

Precedence

If a frame qualifies for different classifications, it is important to be able to specify the classifi-
cation with which it should be associated. There are two mechanisms to address classifica-
tion—a per-contract precedence value and a default ordering. If a contract does not have an
assigned precedence value, then the ordering is as follows:
1. Layer 7 applications (for example, URL, HTTP, headers, cookies, and so forth)
2. Layer 4 services on the virtual server
3. Filter
4. VLAN
5. Source Port/Default Assignment

Bandwidth Classification Configuration

Any item that is configured with a filter can be used for BWM. Bandwidth classification is per-
formed using the following menus:
n
/cfg/slb/filt is used to configure classifications based on the IP destination
address, IP source address, TCP port number, UDP, UDP port number, or any filter rule.
n
/cfg/slb/virt is used to configure classifications based on virtual servers.
n
/cfg/port is used to configure classifications based on physical ports.
(In case of trunking, use /cfg/trunk.)
n
/cfg/vlan is used to configure classifications based on VLANs.
n
/cfg/slb/layer7/lb is used to configure classification based on URL paths.
To associate a particular classification with a contract, enter the contract index into the "cont"
menu option under the applicable configuration menus.
