Router redundancy protocols

Virtual Router Redundancy Protocol Extended (VRRPE) – see “Configuring VRRP and VRRPE” on
page 22-1.

Virtual Router Redundancy Protocol (VRRP) – see “Configuring VRRP and VRRPE” on page 22-1.
The following tables list the Layer 3 Switch IP parameters, their default values, and where to find configuration
information.
NOTE:
For information about parameters in other protocols based on IP, such as RIP, OSPF, and so on, see the
configuration chapters for those protocols.
When Parameter Changes Take Effect
Most IP parameters described in this chapter are dynamic. They take effect immediately, as soon as you enter the
CLI command or select the Web management interface option. You can verify that a dynamic change has taken
effect by displaying the running-config. To display the running-config, enter the
show running-config
or
write
terminal
command at any CLI prompt. (You cannot display the running-config from the Web management
interface.)
To save a configuration change permanently so that the change remains in effect following a system reset or
software reload, save the change to the startup-config file.
•
To save configuration changes to the startup-config file, enter the
write memory
command from the
Privileged EXEC level of any configuration level of the CLI.
•
To save the configuration changes using the Web management interface, select the Save link at the bottom of
the dialog. Select Yes when prompted to save the configuration change to the startup-config file on the
device’s flash memory. You also can access the dialog for saving configuration changes by clicking on
Command in the tree view, then clicking on Save to Flash.
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
Table 16.2 lists the IP global parameters for Layer 3 Switches.
Table 16.2: IP Global Parameters – Layer 3 Switches
Parameter
Description
Default
See page...
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.
