IP global parameters – Layer 2 Switches
Description
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
A Layer 3 network interface address
NOTE: Layer 2 Switches have a single IP address
used for management access to the entire
device. Layer 3 Switches have separate IP
addresses on individual interfaces.
The IP address of a locally attached router (or a router
attached to the Layer 2 Switch by bridges or other
Layer 2 Switches). The Layer 2 Switch and clients
attached to it use the default gateway to
communicate with devices on other subnets.
A standard IP mechanism that networking devices
use to learn the Media Access Control (MAC) address
of another device on the network. The Layer 2 Switch
sends the IP address of a device in the ARP request
and receives the device MAC address in an ARP reply.
The amount of time the device keeps a MAC address
learned through ARP in the device 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.
The maximum number of routers (hops) through
which a packet can pass before being discarded.
Each router decreases a packet TTL by 1 before
forwarding the packet. If decreasing the TTL causes
the TTL to be 0, the router drops the packet instead of
forwarding it.
A domain name (example: brocade.router.com) you
can use in place of an IP address for certain
operations such as IP pings, trace routes, and Telnet
management connections to the router.
A list of gateways attached to the router through
which clients attached to the router can reach DNSs.
The IP address the Layer 2 Switch uses as the source
address for Telnet, RADIUS, or TACACS/TACACS+
packets originated by the router. The Layer 2 Switch
uses its management IP address as the source
address for these packets.
Default
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.
