Foundry Switch and Router Installation and Configuration Guide
8 - 12
December 2000
•
Upgrade boot or flash code.
•
Archive boot or flash code or a configuration file on a TFTP server.
•
Load the system using flash code and a configuration file stored on a TFTP server. (This occurs as part of
the BootP or DHCP process.)
NOTE:
Certain boot upgrades may require you to install new firmware. Contact your reseller or Foundry
Networks for information.
See “Updating Software Images and Configuration Files” on page 7-1 for more information about using TFTP on
Foundry devices.
Simple Network Time Protocol (SNTP)
Foundry devices can use either of two time and date sources:
•
An on-board system clock.
•
An external SNTP server. The server can be on the same sub-net or a different sub-net.
If you have access to an SNTP server, Foundry Networks recommends that you use the SNTP server as the time
and date source. Using an SNTP server ensures that all devices that use the SNTP server have a consistent time
and date. In addition, the settings on the system time counter are not retained across power cycles. The counter
has to be reset following each power-up. If the device is configured to reference an SNTP server, the device
automatically sets its time counter according to the SNTP server after a system reset.
Regardless of the time and date source you use, you can configure the time zone of the time and date. You also
can enable daylight savings time, which is disabled by default.
See “Setting the System Clock” on page 10-12 for more information about setting the time and date.
Domain Name Server (DNS) Resolver
The DNS Resolver feature allows you to use just a host name rather than a fully-qualified domain name when you
use Telnet, ping, and trace-route commands. To configure the feature, you specify the domain name, then specify
the IP addresses of up to four DNS servers that have authority for the domain.
For example, if you define the domain “newyork.com” on a Foundry device, you can initiate a ping to a host on that
domain by specifying only the host name in the command. You do not need to specify the host’s entire domain
name.
As an example, here are two CLI commands. The first command uses only the host name. The second
command uses the fully-qualified domain name for the host.
BigIron# ping nyc01
BigIron# ping nyc01.newyork.com
See “Configuring Domain Name Server (DNS) Resolver” on page 15-23 for information about configuring this
feature.
SNMPv2c Support
Foundry devices support SNMPv2c, including support for GetBulk requests. The SNMPv2c support is enabled by
default and cannot be disabled. Thus, you do not need to perform any configuration on the device to use the
feature. SNMPv1 also is enabled by default.
NOTE:
You can disable all SNMP access to the device if needed. See “Disabling SNMP Access” on page 3-8.
To use this enhancement, you need an SNMP management application that is capable of sending GetBulk
requests. See the documentation for your application for more information.
