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.
