Setting Match Conditions for Class Maps
Step 5 In the Match Condition Type field, select the match condition type for this class map and configure any
match-specific criteria as described in Table 12-10.
Table 12-10 RTSP 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.
RTSP Header The name and value in an RTSP header are used to establish a match condition.
1. In the Header Name field, specify the header in one of the following ways:
– To specify an RTSP header that is not one of the standard RSTP headers, select the first
radio button and enter the RTSP header name in the Header Name field. Valid entries are
unquoted text strings with no spaces and a maximum of 64 characters.
– To specify one of the standard RTSP headers, select the second radio button and select
one of the RTSP 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 RTSP 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.
RTSP URL A URL or portion of a URL is used to establish a match condition.
1. In the URL Expression field, enter a URL, or portion of a URL, to match. The ACE performs
matching on whatever URL string appears after the RTSP method, regardless of whether the
URL includes the host name. The ACE supports regular expressions for matching URL
strings. See Table 12-33 for a list of the supported characters that you can use in regular
expressions.
2. In the Method Expression field, enter the RTSP method to match. Valid entries are unquoted
text strings with no spaces and a maximum of 64 alphanumeric characters. The method can be
either one of the standard RTSP method names (DESCRIBE, ANNOUNCE,
GET_PARAMETER, OPTIONS, PAUSE, PLAY, RECORD, REDIRECT, SETUP,
SET_PARAMETER, TEARDOWN) or a text string that must be matched exactly (for
example, STINGRAY).
Source Address The source IP address is used to establish a match condition.
1. In the Source Address field, enter the source IP address for this match condition in
dotted-decimal format, such as 192.168.11.1.
2. In the Source Netmask field, select the subnet mask for the source IP address.
