Setting Match Conditions for Class Maps
Step 6 Do the following:
• Click Deploy Now to deploy this configuration on the ACE and to return to the Match Condition

Note If you click Deploy Now, the ACE drops the traffic and then restarts it, even if you have not
made changes. If you have not altered existing match conditions, click Cancel instead of
Deploy Now to ensure uninterrupted traffic.
• Click Cancel to exit this procedure without saving your entries and to return to the Match Condition
table.
• Click Next to configure another match condition for this class map.

Table 12-11 SIP Server Load Balancing Class Map Match Conditions
Match Condition Description
Class Map A class map is used to establish a match condition.
In the Class Map field, select the class map to use for this match condition.
SIP Header A SIP header name and value are used to establish a match condition.
1. In the Header Name field, specify the header in one of the following ways:
– To specify a SIP header that is not one of the standard SIP headers, select the first radio
button and enter the SIP header name in the Header Name field. Enter an unquoted text
string with no spaces and a maximum of 64 characters.
– To specify one of the standard SIP headers, select the second radio button and select one
of the SIP headers from the list.
2. In the Header Value field, enter the header value expression string to compare against the
value in the specified field in the SIP header. Valid entries are text strings with a maximum of
255 alphanumeric characters. The ACE supports regular expressions for matching. If the
string includes spaces, enclose the string with quotes. All headers in the header map must be
matched. See Table 12-33 for a list of the supported characters that you can use in regular
expressions.
Source Address The source IP address is used to establish a match condition.
1. For the IP Address Type, select either IPv4 or IPv6 for the address type.
2. In the Source IP Address field, enter the source IP address for this match condition in the
format based on the address type (IPv4 or IPv6).
3. For an IPv4 source address, in the Source Netmask field, select the subnet mask of the IP
address.
For an IPv6 source address, in the Source Prefix-length field, enter the prefix length for the
address.
