CCNA2 (Chapter10)

The administrator needs to do nothing, because Cisco routers send log messages for all severity levels to the console by default. Refer to curriculum topic: 10.2.3 By default, Cisco routers and switches send log messages for all severity levels to the console.

syslog service timestamps Refer to curriculum topic: 10.2.2 Syslog service timestamps provide the ability for log messages to be time-stamped. Syslog severity levels provide the ability for an administrator to filter out log messages. Syslog facilities and service identifiers provide administrators with an event identification and categorization system.

- The IP address of the time source for the router is 192.168.1.1. - The router is attached to a stratum 2 device. Refer to curriculum topic: 10.2.1 The show ntp status command displays information about how NTP is operating on the device. The output shows that the router clock is synchronized with the NTP server with the address of 192.168.1.1. NTP is hierarchical. The router is a stratum 3 device, therefore it's time source is a stratum 2 device. Authoritative time sources in the NTP system are located at stratum 0.

Reload the router Refer to curriculum topic: 10.3.4 The installation steps are as follows: 1. purchase the license key 2. use the license accept end user agreement command to accept the EULA 3. use the license boot module command to activate the license 4. reload the router 5. use the show license all command to verify the installation

syslog security levels Refer to curriculum topic: 10.2.2 Syslog severity levels provide the ability for an administrator to filter out log messages. Syslog service timestamps provide the capability for log messages to be time-stamped. Syslog facilities and service identifiers provide administrators with an event identification and categorization system.

Router(config)# no cdp run Router(config-if)# cdp enable Refer to curriculum topic: 10.1.1 CDP should be used carefully. It is frequently necessary to control which interfaces are running CDP. A good way to do this is to disable CDP in global configuration mode with the no cdp run command, and then to configure specific interfaces with the cdp enable command. CDP is configured on an interface with a single command for both sending and receiving advertisements. LLDP allows configuration of either the send or receive functions with separate transmit and receive commands.

uck9 Refer to curriculum topic: 10.3.5 The uck9 package is for Cisco Unified Communications, which includes support for voice over IP and video.

One advantage of viewing syslog messages on a syslog server is the ability to perform detailed searches through the data. Refer to curriculum topic: 10.2.3 In order for syslog messages to be viewed, a syslog server must be installed on a computer in the network. There are several freeware and shareware versions of syslog, as well as enterprise versions for purchase. Network administrators can easily navigate the large amount of data that is compiled on a syslog server. One advantage of viewing syslog messages on a syslog server is the ability to perform granular searches through the data. A syslog server is a database of informational messages that are received from network devices.

Refer to curriculum topic: 10.2.2

a combination of the product ID, the serial number, and the hardware version Refer to curriculum topic: 10.3.4 Beginning with IOS 15.0, Cisco modified the process of package licensing. In order to obtain a license for a technology package, the Unique Device Identifier is required along with the Product Activation Key (PAK). The UDI is a combination of the product ID (PID), the serial number (SN), and the hardware version (VID).

0x2102 Refer to curriculum topic: 10.3.1 The default configuration register setting on a Cisco router is 0x2102. This can be seen by executing the command router# show version.

Messages with severity level of 6 or higher appear only on the router console output. Refer to curriculum topic: 10.2.3 When these commands are issued, the only messages that appear on the syslog server are those with severity level of 5 or lower. The messages with severity level of 6 or higher appear on the router console output, but do not appear on the syslog server output because the logging trap command limits by severity level the syslog messages that are sent to the syslog server.

The IP address of the neighbor Refer to curriculum topic: 10.1.1 The show cdp neighbors detail command will display the IP address of the neighbor. The show cdp neighbors command displays the platform, capabilities, and name of neighbors, but does not specify IP addresses.

60 days Refer to curriculum topic: 10.3.5 Evaluation licenses are good for a 60 day period. After 60 days the evaluation license will automatically change to a Right-To-Use license.
