Severity: 4-Minor

Symptoms

UDP profiles have a setting to set the Maximum Buffer Packets for UDP connections. This value cannot be modified with an iRule.

Impact

Unable to dynamically change the max buffer packets setting in an iRule.

Conditions

-- UDP profile is used. -- You need to dynamically change the max buffer packets setting in an iRule.

Workaround

None

Fix Information

You can now dynamically change the max buffer packets setting in an iRule. The setting is UDP::max_buf_pkts

Behavior Change

A new iRule command has been added, UDP::max_buf_pkts. This allows you to dynamically override the maximum number of packets setting in the UDP profile.
