IP global parameters
Parameter Description
IP state The Internet Protocol, version 4
IP address and mask Format for displaying an IP address and its network mask
notation information. You can enable one of the following:
•
Class-based format; example: 192.168.1.1 255.255.255.0
•
Classless Interdomain Routing (CIDR) format; example:
192.168.1.1/24
Router ID The value that routers use to identify themselves to other routers
when exchanging route information. OSPF and BGP4 use router
IDs to identify routers. RIP does not use the router ID.
IP Maximum The maximum length an Ethernet packet can be without being
Transmission Unit fragmented.
(MTU)
Address Resolution A standard IP mechanism that routers use to learn the Media
Protocol (ARP) Access Control (MAC) address of a device on the network. The
router sends the IP address of a device in the ARP request and
receives the device's MAC address in an ARP reply.
ARP rate limiting Lets you specify a maximum number of ARP packets the device
will accept each second. If the device receives more ARP packets
than you specify, the device drops additional ARP packets for the
remainder of the one-second interval.
ARP age The amount of time the device keeps a MAC address learned
through ARP in the device's ARP cache. The device resets the
timer to zero each time the ARP entry is refreshed and removes
the entry if the timer reaches the ARP age.
NOTE: You also can change the ARP age on an individual
Proxy ARP An IP mechanism a router can use to answer an ARP request on
behalf of a host, by replying with the router's own MAC address
instead of the host's.
Static ARP entries An ARP entry you place in the static ARP table. Static entries do
not age out.
