■
Use to enable a directed broadcast address in a profile.
■
Example
host1(config-if)# ip directed-broadcast
■
Use the no version to remove the directed broadcast address from the profile.
■
See ip directed-broadcast
ip mtu
■
Use to assign the MTU size sent on an IP interface.
■
Example
host1(config-if)# ip mtu 5000
■
Use the no version to remove the assignment from the profile.
■
See ip mtu
ip redirects
■
Use to enable the sending of redirect messages if the software is forced to resend
a packet through the same interface on which it was received.
■
Example
host1(config-if)# ip redirects
■
Use the no version to remove the assignment from the profile.
■
See ip redirects
ip tcp adjust-mss
■
Use to modify the maximum segment size (MSS) for TCP SYN packets traveling
through the interface. The router compares the MSS value of incoming or outgoing
packets against the MSS adjustment value. For any packet that contains an MSS
value larger than the MSS adjustment value, the router replaces the MSS option
with the configured adjustment value. If the packet does not contain an MSS
value, the router assumes a value of 536 for the packet MSS on which to base
the comparison.
NOTE: The purpose behind using MSS is to alleviate problems with Path MTU
Discovery (PMTUD) and resulting “black hole” detection issues. (See RFC 2923, “TCP
Problems with Path MTU Discovery,” for additional information about the “black
hole” scenario.)

Example
host1(config-if)# ip tcp adjust-mss 5000
