IP Global Parameters – Layer 3 Switches
Table 15.1 lists the IP global parameters for Layer 3 Switches.
Parameter Description
IP state The Internet Protocol, version 4
IP address and Format for displaying an IP address and its network
mask notation mask information. You can enable one of the
following:
•
•
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.
Address A standard IP mechanism that routers use to learn
Resolution the Media Access Control (MAC) address of a device
Protocol (ARP) 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 Lets you specify a maximum number of ARP packets
limiting 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.
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 An ARP entry you place in the static ARP table.
entries Static entries do not age out.

addresses, but you
can enter addresses in
