Basic IP parameters and defaults – Layer 3 Switches
Changes to memory allocation require you to reload the software after you save the changes to the
startup-config file. When reloading the software is required to complete a configuration change
described in this chapter, the procedure that describes the configuration change includes a step
for reloading the software.
IP global parameters – Layer 3 Switches
lists the IP global parameters for Layer 3 Switches.

IP state
The Internet Protocol, version 4
Enabled
NOTE: You cannot
disable IP.
n/a
IP address and
mask notation
Format for displaying an IP address and its network
mask 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
Class-based
NOTE: Changing this
parameter
affects the
display of IP
addresses, but
you can enter
addresses in
either format
regardless of the
display setting.
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.
The IP address
configured on the
lowest-numbered
loopback interface.
If no loopback interface
is configured, then the
lowest-numbered IP
address configured on
the device.
Maximum
Transmission
Unit (MTU)
The maximum length an Ethernet packet can be
without being fragmented.
1500 bytes for Ethernet
II encapsulation
1492 bytes for SNAP
encapsulation
Address
Resolution
Protocol (ARP)
A standard IP mechanism that routers use to learn
the Media 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
MAC address in an ARP reply.
Enabled
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.
Disabled
