TCP MSS clamping configuration commands
Specify the following CLI (under existing interface <iftype> <ifname>):
Note: For a given interface and protocol (IPv4 or IPv6), you can configure only one type of MSS clamping.
ip tcp-mss mtu- For IPv4, sets TCP maximum MSS to interface MTU, less default IP and TCP header sizes.
ipv6 tcp-mss mtu- For IPv6, sets TCP maximum MSS to interface MTU, less default IP and TCP header sizes.
ip tcp-mss mtu-minus <value>- For IPv4, sets TCP MSS to interface MTU, less default IP and TCP header sizes, and with subtraction of an an additional value that you specify. Where
<value>is a number in the range from 1 to 65535. ipv6 tcp-mss mtu-minus <value>- For IPv6, sets TCP MSS to interface MTU, less default IP and TCP header sizes, and with subtraction of an additional value that you specify. Where
<value>is a number in the range from 1 to 65535. ip tcp-mss limit <value>- For IPv4, set TCP MSS to a specific value. Where
<value>is a number in the range from 1 to 65535. ipv6 tcp-mss limit <value>- For IPv6, set TCP MSS to a specific value. Where
<value>is a number in the range from 1 to 65535.
