IP Profiles Overview

You can configure an IP interface dynamically by creating a profile. A profile is a set of characteristics that acts as a pattern that can be dynamically assigned to an IP interface. You can manage a large number of IP interfaces efficiently by creating a profile with a specific set of characteristics. In addition, you can create a profile to assign an IP interface to a virtual router.

A profile can contain one or more of the following characteristics:

• access-route—Enables the creation of host access routes on an interface
• address—Configures an IP address on an interface
• auto-configure—Configures the interface for auto-configure mode
• auto-detect—Configures the interface for auto-detect mode
• directed-broadcast—Enables directed broadcast forwarding
• filter-options-all—Enables filtering of packets with IP options on an interface
• igmp—Configures an Internet Group Management Protocol (IGMP) interface
• ignore-df-bit—Specifies that the don’t-fragment bit is ignored
• inactivity-timer—Configures inactivity time for IP interfaces
• inspection—Associates an inspection list to the interface for firewalling
• mtu—Configures the maximum transmission unit for a network
• nat—Configures the interface as inside or outside for Network Address Translation (NAT)
• policy—Assigns a policy to the ingress or egress of an interface
• redirects—Enables transmission of Internet Control Message Protocol (ICMP) redirect messages
• route-maps—Configures the interface for route-map processing
• source address validation—Verifies that a packet has been sent from a valid source address
• tcp adjust-mss—Adjusts maximum packet sizes on TCP connections when path maximum transmission unit detection is not sufficient
• unnumbered—Configures IP on this interface without a specific address
• virtual-router—Specifies a virtual router to which interfaces created by this profile will be attached
