config slb global synguard
config slb global synguard max-unacknowledged-SYNs <number>
Description
Configures the the SYN-guard feature.
Syntax Description
Default
The default value is 50.
Usage Guidelines
If the number of half-open connections exceeds the number specified, the switch immediately ages out
the half-open connections. This only applies to connections from the same source IP address.
SYN-guard is disabled by default. To enable SYN-guard, use the following command:
enable slb global synguard
SYN-guard is automatically enabled if you configure a
max-unacknowledged-SYNs
value greater than 0.
A
max-unacknowledged-SYNs
value of 0 automatically disables SYN-guard.
Example
The following command configures the SYN-guard feature to age out half-open connections from the
same source IP address when the number of connections exceeds 30:
config slb global synguard max-unacknowledged-SYNs 30
History
This command was first available in ExtremeWare 6.1.
Platform Availability
This command is available on all “i” series platforms.
max-unacknowledged-SYNs
Specifies the number of half-open connections that the switch allows. The
range is 10 to 4000.
